Question HelpQuestion 28: Video1
Answer:
88%
Step-by-step explanation:
(73+75+84+x)/4=80
x4 to both sides
73+75+84+x=80x4
73+75+84+x=320
232+x=320
x=320-232
x=88
Answer:
88
Step-by-step explanation:
80*4 = 320 320- (73 + 75 +84 ) = 88 we can cross out 320/80 = 32/8 and 232/320 = 232 /4 (320/4) and divide each side by 4 = 58 / 80 then 29/40 = 40-29 = 11 then decimalise /10 = 1.1 then multiply 80 * 1.1 = 88

The down payment makes the monthly loan payment fit into Isabel's budget. Besides this benefit, do you
think saving for a down payment on the car was worth it for Isabel? Useeach monthly payment with and
without a down payment) to find the difference of the total amount paid for the car in each scenario to
justify your answer.
Answer:
students should use the monthly payment provided if no down payment is made to find the total amount she'll pay over the course of her loan.
Step-by-step explanation:
Edmentum Financial Math Unit3 Activity on yt 20:58
Answer: Yes, it is worth putting the down payment down as it ends up saving her roughly $865.60.
Step-by-step explanation:
Yes, I think it was worth saving up to put a down payment down. I think this because over time it lowered her interest rate causing her to safe roughly just under a thousand dollars. Without the down payment she would have payed a little under 25 thousand dollars, but with the down payment she is now instead paying a total of just under 24 thousand dollars. I found this out from multiplying the amount she was paying per month based off of if it was with or without a down payment ($412.22 per month without the down payment, and 314.46 per month with the down payment of 5000 dollars) then I would multiply those numbers by 12 and then 5. 12 representing the amount of months per year she is paying and the 5 representing the total amount of years it will take to have it payed off. If it has to be exact though, then the exact dollar amount that the with down payment and without the down payment would be $865.60. That number represents the total she saved when making the down payment after the five years.

One number exceeds another by 20 and their sum is 30. Find the two numbers.
Answer:
25 & 5
Step-by-step explanation:
x+x+20=30
2x+20=30
2x=10
x=5
x+20=25
If One number exceeds another by 20 and their sum is 30 then the two numbers are 5 and 25.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that One number exceeds another by 20 and their sum is 30.
By the given data the two numbers are x+20 and x
As the sum of two numbers is 30
x+x+20=30
Add the like terms
2x+20=30
Subtract 20 on both sides
2x=10
Divide both sides by 2
x=5
So the two numbers are 5 and 5+20 which is 25
Hence, the two numbers are 5 and 25.

Answer:
72
Step-by-step explanation:
Don't worry my friend, we have the power of order of operations!!
Okay, so first start by replacing the variables with the given numbers.
a(b - 1)^2 = 8(4 - 1)^2
Now do whats in the parentheses.
(4 - 1) = (3)
Next, we do 3 x 3 . This is because the three is squared.
(3)^2 = 9
Finally, multiply by 8.

Consider the line y = - 5/4 x+7
What is the slope of a line parallel to this line?
What is the slope of a line perpendicular to this line?
Answer:
-5/4
4/5
Step-by-step explanation:
Given expression ,
=> y = -5/4x + 7
Comparing to the slope intercept form,
m = -5/4As we know that the slope of two parallel lines is same . So the slope of the line parallel to given line will be -5/4 .
Again we know that the product of slope of two perpendicular lines is-1 . Hence ,
=> m' * -5/4 = -1
=> m = 4/5
Answer:
parallel: -5/4; perpendicular: 4/5
Step-by-step explanation:
parallel lines have the same slope
perpendicular lines have the slope that is the negative reciprocal of the original slope (basically the upside down negative slope)
What is 9 times two thirds
Answer:
6
Step-by-step explanation:
9*2/3=3*2=6 (Cross Cancelling)
Answer: 6
Step-by-step explanation:
So basically, you can figure this out by turning 9 into a fraction, which is [tex]\frac{9}{1}[/tex]. So,
[tex]\frac{9}{1}[/tex] x [tex]\frac{2}{3}[/tex] and multiply it across. So 9 x 2 is 18, and 1 x 3 is 3, so that gets us to [tex]\frac{18}{3}[/tex]. And since this is an improper fraction, we divide 18 by 3 to get 6! Hope this helps! :)

Copy the figure at right. Calculate the measure
of each lettered angle. Explain
how you determined the
measures d and h.
The angles of each letter are as follows:
∠a = 124°
∠b = 56°
∠c = 56°
∠d = 38°
∠e = 38°
∠f = 76°
∠g = 66°
∠h = 104°
∠k = 76°
∠n = 86°
∠p = 38°
∠a = 180 - 56 = 124°(total angle on a straight line)
∠b = 56°(vertically opposite angles)
∠c = 56°(corresponding angle to ∠b) Note this is possible because there are 2 parallel lines and a transversal.
2∠d + ∠d + 66 = 180 (sum of angles in a triangle)
3∠d = 180 - 66
3∠d = 114
∠d = 114 / 3
∠d = 38°
∠d = ∠e (given)
Therefore,
∠e = 38°
∠d + 66 + ∠f = 180
38 + 66 + ∠f = 180
∠f = 76°
Recall external angle of a triangle is equals to the sum of the opposite angles. Therefore,
∠f + ∠g = ∠d + ∠h
∠f + ∠g = 38 + 104
76 + ∠g = 142
∠g = 66°
∠d is one of the base angles of an isosceles triangle. Therefore base angles of the isosceles triangle are equal. This means the other base angle opposite ∠d in the isosceles triangle is congruent to ∠d.
Therefore,
2∠d + ∠h = 180(sum of angles in a triangle)
76 + ∠h = 180
∠h = 180 - 76
∠h = 104°
∠h + ∠k = 180 (sum of angles on a straight line)
∠k = 76°
∠n = 180 - ∠d - ∠c (angles on a straight line)
∠n = 86°
∠p = 180 - 56 - ∠n (sum of angle in a triangle)
∠p = 38°
Therefore, the angles of the letters are:
∠a = 124°
∠b = 56°
∠c = 56°
∠d = 38°
∠e = 38°
∠f = 76°
∠g = 66°
∠h = 104°
∠k = 76°
∠n = 86°
∠p = 38°

Adam leases a car with an upfront payment of $3,069 and monthly payments of $205.
Assuming there are no additional charges, what will be the total cost of a two-year
lease?
Answer:
Total cost of the lease = $7,989
Step-by-step explanation:
12 months = 1 year. So 2 year = 24 months.
Total cost of the lease = (Monthly cost × number of months) + Upfront pay
Total cost of the lease = ( $205 × 24) + $3,069
Total cost of the lease = $4,920 + $3,069
Total cost of the lease = $7,989

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The number of different reservation numbers that are possible is 17,576 × 10⁶.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
Given that A hotel reservation number consists of 3 digits, followed by 3 letters, followed by 3 digits.
Since each place can be taken by the digits each place will have 10 possible outcomes, [0,9]. Similarly for each place that can be taken by the alphabet can be taken by 26 different digits.
Therefore, the number of different reservation numbers that are possible is,
Number of different reservations = 10 × 10 × 10 × 26 × 26 × 26 × 10 × 10 × 10
= 17,576 × 10⁶
Hence, the number of different reservation numbers that are possible is 17,576 × 10⁶.

What is the slope of a line that passes through points (2,5) and (-6,-3) please help no links either please
Answer:
1
Step-by-step explanation:
if we graph the two points, we can see that the slope rises 8 and runs 8 as well (graph is attached in the picture). this can be written as 8/8, which is equivalent to 1. the y-intercept is 3, so we can write an equation in slope-intercept form. this would be y=1x+3. we can make a table to check this. to find the values in the table, plug the x values (the standard is -2, -1, 0, 1, 2) into the equation. for -2, we would make the equation y=1(-2)+3, which would make y equal to 1. do this for all the other x values.
x - -2, -1, 0, 1, 2
y - 1, 2, 3, 4, 5
to check if this is correct, check if the points are on the graph. they are, so we know that 1 is the slope.
