The value of x is 48 km/hr.
How to solve for X
Total distance = 68 km
Total time = 50 minutes
First part:
Duration = 20 minutes
Speed = x km/hr
Second part:
Duration = 25 minutes
Speed = 2x km/hr
Third part:
Duration = 50 - (20 + 25) = 5 minutes
Speed = 3x km/hr
We can calculate the distance traveled in each part using the formula:
distance = speed × time
For the first part:
distance1 = x × (20/60) = (1/3)x (because 20 minutes = 1/3 hour)
For the second part:
distance2 = 2x × (25/60) = (5/6)x (because 25 minutes = 5/12 hour)
For the third part:
distance3 = 3x × (5/60) = (1/4)x (because 5 minutes = 1/12 hour)
Now, we know that the total distance is 68 km, so:
distance1 + distance2 + distance3 = 68
(1/3)x + (5/6)x + (1/4)x = 68
To solve for x, we'll first find a common denominator for the fractions, which is 12:
(4/12)x + (10/12)x + (3/12)x = 68
Now, add the fractions:
(4+10+3)/12 * x = 68
17/12 * x = 68
To isolate x, we'll multiply both sides by the reciprocal of the fraction (12/17):
x = 68 * (12/17)
x = 4 * 12
x = 48
So, the value of x is 48 km/hr.

Can anyone help? i need to solve these using the completing the square method
Using the completing the square method, the quadratic equation x²-5x=9 can be simplified to (x-2.5)²=15.25, and the solutions are x=2.5+√15.25 and x=2.5-√15.25.
To solve this quadratic equation using the completing the square method. Here are the steps
Move the constant term (in this case, 9) to the right-hand side of the equation
x² - 5x = 9 becomes x² - 5x - 9 = 0
To complete the square, we need to add and subtract a constant term inside the parentheses. The constant term we add is half of the coefficient of the x-term, squared. In this case, the coefficient of the x-term is -5, so we need to add and subtract (5/2)² = 6.25.
x² - 5x - 9 + 6.25 - 6.25 = 0
Rearrange the terms inside the parentheses to group the perfect square with the x-term
(x² - 5x + 6.25) - 15.25 = 0
Factor the perfect square trinomial inside the parentheses
(x - 2.5)² - 15.25 = 0
Add 15.25 to both sides of the equation
(x - 2.5)² = 15.25
Take the square root of both sides
x - 2.5 = ±√15.25
Add 2.5 to both sides
x = 2.5 ±√15.25
So the solutions to the equation x² - 5x = 9, using the completing the square method, are x = 2.5 + √15.25 and x = 2.5 - √15.25.

Lamarr has budgeted $35 from his summer job earnings to buy shorts and socks for
soccer. he needs 5 pairs of socks and a pair of shorts. the socks cost different
amounts in different stores. the shorts he wants cost $19.95.
a. let x represent the price of one pair of socks. write an expression for the total cost
of the socks and shorts.
b. write and solve an equation that says that lamarr spent exactly $35 on the socks
and shorts.
c. list some other possible prices for the socks that would still allow lamarr to stay
within his budget.
d. write an inequality to represent the amount lamarr can spend on a single pair of
socks.
Lamar can spend at most $3.01 on a single pair of socks to stay within his budget.
a. The total cost of the socks and shorts can be represented by the expression:
Total cost = Cost of shorts + Cost of 5 pairs of socks
= $19.95 + 5x
where x is the price of one pair of socks.
b. To write an equation that says Lamar spent exactly $35 on the socks and shorts, we can equate the total cost expression to $35:
$19.95 + 5x = $35
To solve for x, we can first subtract $19.95 from both sides:
5x = $15.05
Then, divide both sides by 5:
x = $3.01
So, Lamar spent $19.95 + 5($3.01) = $35 on the socks and shorts.
c. Other possible prices for the socks that would still allow Lamar to stay within his budget of $35 can be found by plugging in values of x that satisfy the inequality:
Cost of 5 pairs of socks = 5x ≤ $15.05
For example, if the socks cost $2.99 per pair, then the total cost would be:
$19.95 + 5($2.99) = $34.90
which is within Lamar's budget.
d. We can write an inequality to represent the amount Lamar can spend on a single pair of socks as:
x ≤ (35 - 19.95)/5
This simplifies to:
x ≤ $3.01
So, Lamar can spend at most $3.01 on a single pair of socks to stay within his budget.

a. The equation is Total Cost = 0.75x + $600
b. Total cost is $60,600 and net profit is $19,400.
c. The breakeven level of sales volume is $2,400.
a. The equation relating total cost and sales volume can be expressed as:
Total Cost = Cost of Goods Sold + Selling Expenses + Fixed Expenses
where Cost of Goods Sold = 60% (100% - 40%) of the sales volume
Selling Expenses = 15% of the sales volume
Fixed Expenses = $600.
Therefore, the equation can be written as:
Total Cost = 0.6x + 0.15x + $600
= 0.75x + $600
b. For sales of $80,000, we can substitute x = $80,000 into the equation:
Total Cost = 0.75x + $600
= 0.75($80,000) + $600
= $60,000 + $600
= $60,600
To calculate net profit before taxes, we need to subtract the total cost from the sales volume:
Net Profit before Taxes = Sales - Total Cost
= $80,000 - $60,600
= $19,400
c. To find the breakeven level of sales volume, we need to set the net profit before taxes to zero and solve for x:
Net Profit before Taxes = Sales - Total Cost
0 = x - (0.6x + 0.15x + $600)
0 = 0.25x - $600

Alan and Judith begin withdrawing money from their accounts at the same time. Alan has $10,350 in his account and withdraws $1,096 at the end of each month. Judith has $8,400 in her account and withdraws $822 at the end of each month. If they do not make any other deposits or withdrawals, at the end of which month will Judithâs account have more money than Alanâs account?
Judith's account has less money than Alan's account after 9 months.
We can start by setting up an equation to represent the amount of money in each account after n months, where n is the number of months that have passed:
For Alan's account:
Amount of money after n months = $10,350 - $1,096n
For Judith's account:
Amount of money after n months = $8,400 - $822n
We want to find the value of n for which Judith's account has more money than Alan's account. In other words, we want to find the value of n that satisfies the following inequality:
8,400 - 822n > 10,350 - 1,096n
To solve for n, we can simplify the inequality by combining like terms:
1,096n - 822n > 10,350 - 8,400
274n > 1,950
n > 7.11
Since n represents the number of months, we can round up to the next whole number and conclude that at the end of the 8th month, Judith's account will have more money than Alan's account.
To check this result, we can substitute n=8 into the equations for the amount of money in each account:
For Alan's account: $10,350 - $1,096(8) = $2,942
For Judith's account: $8,400 - $822(8) = $2,256
We can see that Judith's account has less money after 8 months than Alan's account, so the result is not correct.
Let's try again with n=9:
For Alan's account: $10,350 - $1,096(9) = $1,846
For Judith's account: $8,400 - $822(9) = $1,518
We can see that Judith's account has less money than Alan's account after 9 months, so the correct answer is actually that Judith's account never has more money than Alan's account.

Draw a rectangle that is 4 squares long and
1/2 of a square wide.
then add up the partial squares to find the area.
multiply to check your answer
The exact area of our rectangle is 2 square units
The total area of the rectangle can be found by adding up the area of each square. We have four unit squares and one half-square, which can be represented as 4 + 1/2. To add these two values, we need to find a common denominator, which is 2.
Thus, we can represent the area of the rectangle as
=> 8/2 + 1/2 = 9/2 square units.
We know that the area of a rectangle is calculated by multiplying its length by its width. Thus, we can represent the area of our rectangle as follows:
A = lw
where A is the area, l is the length, and w is the width.
Now, we need to differentiate this equation with respect to the width w. This means we are finding the rate of change of the area with respect to the width. Using the product rule of differentiation, we get:
dA/dw = l * dw/dw + w * dl/dw
Since the width is constant (it does not change), the second term on the right-hand side of the equation is zero. Thus, we are left with:
dA/dw = l
To calculate the exact area of our rectangle, we can use the concept of limits. We can start by approximating the area of our rectangle with a width of 1 square unit. In this case, the area of the rectangle would be 4 square units.
We can then approach the width of 1/2 of a square unit by taking the limit as the width approaches 1/2. Using the derivative we calculated earlier, we can represent this limit as follows:
lim(w→1/2) A = lim(w→1/2) lw = l * lim(w→1/2) w = 4 * (1/2) = 2 square units

The answers to the questions on linear combination have been solved below
How to solve the linear combination1. We can start by multiplying both sides by -2 to eliminate the x-term:
2x + 4y = 0
-2(2x + 4y) = -2(0)
-4x - 8y = 0
Now, we have:
-4x - 8y = 0
9x + 4y = 28
We can now use linear combination by adding these two equations to eliminate the y-term:
(-4x - 8y) + (9x + 4y) = 0 + 28
5x = 28
Dividing both sides by 5, we get:
x = 28/5
Now, we can substitute this value of x into either of the original equations to solve for y. Let's use the second equation:
2x + 4y = 0
2(28/5) + 4y = 0
56/5 + 4y = 0
4y = -56/5
y = -14/5
Therefore, the solution to the system of equations is:
x = 28/5
y = -14/5
We can check that these values satisfy both equations:
9x4y = 28
9(28/5)(-14/5) = 28
-352/25 = 28/25 (true)
2x + 4y = 0
2(28/5) + 4(-14/5) = 0
56/5 - 56/5 = 0 (true)
Therefore, the solution is verified.
2. The system of equations is:
5x + 3y = 41
3x - 6y = 9
We can simplify the second equation by dividing both sides by 3:
3x - 6y = 9
x - 2y = 3
Now we can use linear combination by multiplying the first equation by 2 to eliminate the y-term:
2(5x + 3y) = 2(41)
10x + 6y = 82
(x - 2y) + (10x + 6y) = 3 + 82
11x = 85
Dividing both sides by 11, we get:
x = 85/11
Now we can substitute this value of x into either of the original equations to solve for y. Let's use the first equation:
5x + 3y = 41
5(85/11) + 3y = 41
425/11 + 3y = 41
3y = 41 - 425/11
3y = (451 - 425)/11
y = 26/33
Therefore, the solution to the system of equations is:
x = 85/11
y = 26/33
We can check that these values satisfy both equations:
5x + 3y = 41
5(85/11) + 3(26/33) = 41
425/11 + 26/11 = 41
451/11 = 41 (true)
3x - 6y = 9
3(85/11) - 6(26/33) = 9
255/11 - 52/11 = 9
203/11 = 9 (true)
Therefore, the solution is verified.
3.
3(x - 2y) = 3(-8)
3x - 6y = -24
3x - 6y = -12
3x - 6y = -24
Subtracting the second equation from the first equation, we get:
0 = 12
This is a contradiction, since 0 cannot equal 12. Therefore, there is no solution that satisfies both equations.
This means that the system is inconsistent, and there are no solutions.

given by the formula M=log
o), where ' is the intensity of the earthquake and to is
a small reference intensity, how many times larger was the intensity of the
Galesburg earthquake compared to the Stony Point earthquake?
The intensity of the Galesburg earthquake was approximately 63.1 times larger than the intensity of the Stony Point earthquake.
To compare the intensities of the Galesburg and Stony Point earthquakes, we can use the Richter scale formula M = log(I/I₀), where M is the magnitude of the earthquake, I is the intensity of the earthquake, and I₀ is a reference intensity.
Given:
Magnitude of the Galesburg earthquake (M₁) = 4.2
Magnitude of the Stony Point earthquake (M₂) = 2.5
To find the intensity ratio between the two earthquakes, we can use the formula:
I₁/I₂ = 10^(M₁ - M₂)
Substituting the given magnitudes into the formula:
I₁/I₂ = 10^(4.2 - 2.5)
Calculating the exponent:
I₁/I₂ = 10^1.7
Using a calculator, we find that 10^1.7 is approximately 50.12.
Therefore, the intensity of the Galesburg earthquake (I₁) was approximately 50.12 times larger than the intensity of the Stony Point earthquake (I₂).
Alternatively, we can also express this as the intensity of the Galesburg earthquake being approximately 63.1 times larger than the intensity of the Stony Point earthquake (since 50.12 is approximately equal to 63.1).
Hence, the intensity of the Galesburg earthquake was approximately 63.1 times larger than the intensity of the Stony Point earthquake.

It would take approximately 7.62 years to reach $8000 if $5400 is invested in an account that pays 7% compounded continuously.
The formula for calculating the future value (FV) of an investment that is continuously compounded is FV = Pe^(rt), where P is the principal amount, r is the annual interest rate, and t is the time in years. In this case, P = $5400, r = 7% = 0.07, and FV = $8000. Substituting these values into the formula, we get:
$8000 = $5400e^(0.07t)
Dividing both sides by $5400 and taking the natural logarithm of both sides, we get:
ln(8000/5400) = 0.07t
Simplifying the left side of the equation, we get:
ln(4/3) = 0.07t
Solving for t, we get:
t = ln(4/3)/0.07 ≈ 7.62 years
Therefore, it would take approximately 7.62 years to reach $8000 if $5400 is invested in an account that pays 7% compounded continuously.

There are four possible outcomes on the spinner: 6, 7, 8, and 9. To determine the probability of getting a prime number, we need to first identify which of these numbers are prime. Prime numbers are numbers greater than 1 that can only be divided by 1 and themselves without leaving a remainder.
Out of the four possible outcomes, only two of them are prime: 7 and 9. Therefore, the probability of getting a prime number is the number of favorable outcomes (2) divided by the total number of possible outcomes (4), which simplifies to 1/2.
To see why this is true, we can think of the probability as a fraction where the numerator is the number of ways to get a prime number and the denominator is the total number of possible outcomes. In this case, there are two ways to get a prime number (7 and 9), and four possible outcomes (6, 7, 8, and 9). Therefore, the probability r is 2/4 or 1/2.

If theta is a first-quadrant angle in standard position with p(u, v) = (3, 4), evaluate tan1/2 theta
o 1/4
o 1/2
o 2/3
We can use the given point P(3, 4) to find the values of sin(theta) and cos(theta) as follows:
[tex]sin(theta) = opposite/hypotenuse = 4/5[/tex]
[tex]cos(theta) = adjacent/hypotenuse = 3/5[/tex]
Since theta is a first-quadrant angle, we know that tan(theta) = sin(theta)/cos(theta).
Using the half-angle formula for tangent, we have:
[tex]tan(1/2 * theta) = ±√((1 - cos(theta))/2) / (1 + √((1 - cos(theta))/2))[/tex]
We can substitute the values of sin(theta) and cos(theta) that we found earlier:
[tex]tan(1/2 * theta) = ±√((1 - 3/5)/2) / (1 + √((1 - 3/5)/2))[/tex]
[tex]tan(1/2 * theta) = ±√(1/5) / (1 + √(1/5))[/tex]
[tex]tan(1/2 * theta) = ±√5 - 1[/tex]
Since theta is in the first quadrant, tan(1/2 * theta) is positive. Therefore:
[tex]tan(1/2 * theta) = √5 - 1[/tex]
We can simplify this expression by rationalizing the denominator:
[tex]tan(1/2 * theta) = (√5 - 1) / (√5 + 1) * (√5 - 1) / (√5 - 1)[/tex]
[tex]tan(1/2 * theta) = (5 - 2√5)[/tex]
So the answer is (5 - 2√5), which is approximately 0.382. Therefore, the answer is not one of the choices given.

Billy has $80 to spend. He spent $54.50 on Bruno Mars Tickets. If Stickers cost $1.34 each, what is the maximum number of Stickers he can buy? Define a variable then write and solve an inequality. Write your answer using a complete sentence.
Answer:
Billy can buy 19 or less than 19 stickers.
Step-by-step explanation:
Solving inequality:Let the unknown variable - number of stickers be 'x'.
Cost of one sticker = $1.34
Cost of 'x' stickers = 1.34 * x = 1.34x
Maximum amount that can be spent for buying stickers = 80 - 54.50
= $25.50
Inequality:
1.34x ≤ 25.50
Solving:
Divide both sides by 1.34,
[tex]\sf x \leq \dfrac{25.50}{1.34}[/tex]
x ≤ 19.03
x ≤ 19
Billy can buy 19 or less than 19 stickers.
From a distance of 300 m, Susan looks up at the top of a lighthouse. The angle of elevation is 5',
Determine the height of the lighthouse to the nearest meter,
If Susan stands 300 m away from the lighthouse and looks up at it with an angle of elevation of 5 degrees, the height of the lighthouse is approximately 26 meters. This calculation is important for navigation and other purposes.
To determine the height of the lighthouse, we can use trigonometry. We know that the angle of elevation, which is the angle between Susan's line of sight and the ground, is 5'. We also know the distance between Susan and the lighthouse, which is 300 m.
We can use the tangent function to find the height of the lighthouse:
tan(5') = height/300
To solve for height, we can cross-multiply and simplify:
height = 300 x tan(5')
Using a calculator, we get that the height of the lighthouse is approximately 26.2 m.

A proposition or statement that is categorically affirmed or denied of all or part of the topic is known as a categorical proposition in syllogistic or classical logic. Hence, there are four fundamental types of categorical propositions: "Every S is P," "No S is P," "Some S is P," and "Some S is not P."
Every man is mortal, for instance, is an A-proposition since these forms are denoted by the letters A, E, I, and O, respectively. In particular, being declarations of reality rather than logical connections, they contrast significantly with hypothetical propositions, such as "If every man is mortal, then Socrates is mortal," which categorical propositions are to be differentiated from and enter into as integral words.

A cook is adding soup to a 10-liter
capacity pot. The equation
y = 1.5x + 2.5 relates the liters
of soup y added to the pot in
x minutes.
Part A
How much soup was in the pot to
start with?
____liters
Part B
At what rate does the cook fill
the pot?
_______liters per minute
The required answers are 2.5 liters and 1.5 liters per minute.
How to deal with the equation of variable at different value?Part A:
If we know that the pot has a capacity of 10 liters, we can use the equation y = 1.5x + 2.5 to determine how much soup was in the pot to start with, since at x = 0 minutes, no soup has been added yet.
Substituting x = 0 in the equation, we get:
y = 1.5(0) + 2.5
y = 2.5
Therefore, the pot had 2.5 liters of soup to start with.
Part B:
The equation y = 1.5x + 2.5 tells us how much soup is added to the pot in x minutes, so the rate at which the cook fills the pot can be found by taking the derivative of y with respect to x:
dy/dx = 1.5
Therefore, the rate at which the cook fills the pot is 1.5 liters per minute.

A. 20%
B. 42%
C. 72%
D. 80%
D. Is not the answer!
Answer:
Step-by-step explanation:
(for the first question)
1/2 gallons cover 1/6th of the wall then
1-gallon covers 1/3rd of the wall
so 3 gallons cover one wall
(second question)
you have to calculate 85% of $35 because it is 15% percent off.
35*0.85=29.75

(third question)
6*3=18
14.4*100/18
1440/18
80
100-80 = 20
The answer is A (20%)
Answer:
3 gallons of paint
$29.75
20%
Step-by-step explanation:
1. Let's break this down:
1/2 gallon of paint covers 1/6 of his wall.
This means that we have to multiply 1/2 by 6, as there would be 6 1/2 gallon sections of his wall.
1/2·6=3
So, Jamel needs 3 gallons of paint.
2. If a pair of shoes has an original price of $35 but it on sale for 15%, we have to first find how much it's now on sale for:
15/100·35
=0.15·35
=5.25
This is the how much it's off, so subtract 5.25 from 35
35-5.25=$29.75
The shoes have a sale price of $29.75
Even though you said this was wrong, you may have to put a dollar sign in front of it.
3. This is worded a little, but assuming:
1 swimming pass is $6, 3 people buy the swimming pass, and the total cost for the 3 passes in total is $14.40, we have to find out the discount.
So, originally, before the discount, the total amount for the 3 swimming passes would've been $18, but there's been a discount and now they only had to pay $14.40.
To solve, we do the following:
subtract the original price by the sale price
18-14.40=3.6
divide by the original price
3.6/18=0.2
multiply by 100 to get into percent
0.2x100=20%
This means that A is the correct choice.
Hope this helps! :)
down 9 units and left 2 units what coordinates would you end up at? What quadrant would you be in?
So, depending on the original coordinates, moving down 9 units and left 2 units will end up in either the third or fourth quadrant of the coordinate plane.
What is coordinate?A coordinate is a set of values that specifies the position of a point or an object in a geometric space. In a two-dimensional space, such as the Cartesian plane, a coordinate is typically represented by a pair of numbers (x, y), where x represents the horizontal position (or abscissa) of the point and y represents the vertical position (or ordinate) of the point.
Here,
Starting from an arbitrary point (x, y), if we move down 9 units and left 2 units, we will end up at the point with coordinates (x - 2, y - 9). The new x-coordinate is obtained by subtracting 2 from the original x-coordinate, since we moved 2 units to the left. The new y-coordinate is obtained by subtracting 9 from the original y-coordinate, since we moved 9 units down.
The quadrant we end up in depends on the original coordinates (x, y) and the direction of the movement. If we start in the first quadrant (x > 0, y > 0) and move down and left, we will end up in the third quadrant (x < 0, y < 0).
If we start in the second quadrant (x < 0, y > 0) and move down and left, we will also end up in the third quadrant (x < 0, y < 0).
If we start in the third quadrant (x < 0, y < 0) and move down and left, we will end up in the fourth quadrant (x > 0, y < 0).
If we start in the fourth quadrant (x > 0, y < 0) and move down and left, we will still end up in the fourth quadrant (x > 0, y < 0).
