Answer:
$58.40
Step-by-step explanation:
Really simple stuff here once you know how percentages work.
10% of 73.00 is 7.30, which means that if we do:
7.30 * 2 that means we have 20%
So, 7.30 * 2 = 14.60
73.00 - 14.60 = $58.40
We can check this by doing
7.30 * 8 = $58.40
47/94 in lowest terms
Answer:
Find the GCD (or HCF) of numerator and denominator. GCD of 47 and 94 is 47.
47 ÷ 4794 ÷ 47.
Reduced fraction: 12. Therefore, 47/94 simplified to lowest terms is 1/2
Step-by-step explanation:
Answer:
1/2
Step-by-step explanation:
You just keep simplifying.
Find the GCD of the numerator and denominator. The GCD of 47 and 94 is 47.
47 divided by 4794 divided by 47
Reduced fraction: 12. So 47/94 simplified is 1/2

PLEASE HELP a
23. A cell phone company charges $0.10 per
text message if a customer sends up to 100
messages per month. The company charges
$0.08 per text if a customer sends between
101-200 messages, and $0.06 per text if the
customer sends between 201-300 messages.
Today is the last day of the month. Tamira has
sent 200 text messages, is it worth it for her
to send 1 more text message? Explain.
SEE EXAMPLES 3 AND 4
The rate of the cell phone company is an illustration of a linear equation
It is worth it if Tamira sends an additional message
The parameters are given as:
Rate = 0.10 per message for up to 100 messages
Rate = 0.08 per message from 101 to 200 messages
Rate = 0.06 per message from 201 to 300 messages
If Tamira sends 200 messages, the total charge is:
[tex]\mathbf{Total = 0.08 * 200}[/tex]
[tex]\mathbf{Total = \$16}[/tex]
If Tamira sends an additional message to make it 201 messages, the total charge is:
[tex]\mathbf{Total = 0.06 * 201}[/tex]
[tex]\mathbf{Total = \$12.06}[/tex]
By comparison.
$12.06 is less than $16
This means that she spends less is she sends 201 messages.
Hence, it is worth it if Tamira sends an additional message

What's the increasing & decreasing interval of f(x)=1/2|x+7|?
Answer:
Increasing interval is for all values of x that the function is defined by, in other words x is greater or equal to 0.
And there are not decreasing intervals.
Increasing interval is when the slope of the tangent at the function is positive.
Decreasing interval is when the slope of the tangent at the function is negative.
A car is traveling at a constant speed of M miles per hour. Which coordinate is
represented on the graph?
The cordinate of a car driving at M miles per hour on a graph is ( 1, M)
What is cordinate?Coordinates are a set of values which helps to show the exact position of a point in the coordinate plane.
The cordinate of a point Q is represented by
Q( a, b) where a is the cordinate on x axis and b is the cordinate on y axis.
For example is a point B is located on a plane as ;
B( 2,3) , the 2 is the value on x axis and 3 is the value on y axis.
Therefore, For a speed of a car of M miles in 1hr, then
Speed = distance /time
This means on the graph , M will be on y axis and 1 hrs will be on x axis.
Therefore the cordinate of the speed of the car is
( 1, M)

Evaluate the expression 0.5a - 2b , when a=-5 and b=2
Answer:
-6.5
Step-by-step explanation:
To evaluate the expression we have to substitute a= -5 and b =2.
0.5a - 2b
= 0.5 * (-5) - 2 *2 , first multiply 0.5 *(-5) and 2*2
= -2.5 - 4, subtract (-2.5) and 4
(you can think at this as (- 2.5) +( - 4) because subtraction is just like adding a negative number )
= -6.5

Benjamin has a ladder that is 15ft long. He wants to lean the ladder against a vertical wall so that the top of the ladder is 13.8ft above the ground. What is the angle, rounded to the nearest tenth, that the ladder make with the ground? Show your work.
Answer:
∠ = 66.9°
Step-by-step explanation:
Sin ∠ = opposite/hypotenuse
Sin ∠x = 13.8/15
In the graphing calculator use
[tex]sin^{-1}(13.8/15) = 66.9[/tex]
The angle to the nearest tenth is 66.9 degrees.
In order to determine the angle, the SOCAHTOA notation would be used. The ladder would form a right-angled triangle. we have the value of the opposite and the hypotenuse. So, sine would be used to determine the value of the angle.
Sine = opposite / hypotenuse
[tex]sine^{-1}[/tex] = 13.8 / 15
= 66.9 degrees

Answer:
See below:
Step-by-step explanation:
Hello! My name is Galaxy and I will be helping you today :DD. I hope you are having a nice day.
So based on the question we need to do two steps, Rules of Exponents, and Solving. I'll go ahead and start with Exponential Rules first.
Rules of Exponents
The rules of exponents are simple, they boil down to a few things at this level of math:
+ To Multiply Exponents, we can add the Exponents of the Bases.
(Example: [tex]x^{2}*x^{3}=x^{5}[/tex])
+ To Divide Exponents, we need to subtract the Exponents of the Bases.
(Example: [tex]\frac{x^{5} }{x^3}=x^2[/tex])
Now that we know that, we can solve for the equation.
Solving
So, we need to solve for the blanks in this equation:
[tex]3^8*x^8=12^y[/tex]
**Where x and y are unknown.
So, first we know that for the multiplication of exponents, we need to add the exponent, so with that we know that it has to be 8 giving us our y.
Second of all, we know to multiple and solve for x we need to divide 12 by 3.
After doing that, and using basic math, we get x is equal to 4.
We can check our answers by inserting what we found into the equation:
[tex]3^8*4^8=12^{8}\\\\429981696=429981696[/tex]
Therefore, the answers are:
First blank is equal to 4, and the second blank is equal to 8.
We've checked our answers and they are correct!

II. Find the mean, media and mode of each set of data.
1. 12, 12, 14, 16, 18, 20
2. 80, 83, 82, 85, 87, 93, 83, 85, 88, 80
3. 125, 100, 150, 125, 175
Answer:
1. Mean = 15.33
Median = 15
Mode = 12
2. Mean = 84.6
Median = 84
Mode = 80, 83, 85
3. Mean = 135
Median = 125
Mode = 125
Step-by-step explanation:
Hope it helps:)
I. Mean = Sum of all observations / No. of observations
=> 12 + 12 + 14 + 16 + 18 + 20 / 6
=> 92 / 6
= 15.33333.....
= 15.3
Mode = 12
Because 12 is occurring most frequently.
Median
Step 1 => Arrange the values in ascending order.
Step 2 => Then the middle observation will be the median of the data.
Here we will get 2 numbers as the median but since it is not applicable we will use another method.
12, 12, 14, 16, 18, 20
Find average of 14 and 16
14 + 16 / 2
30 / 2 = 15
Therefore Median of the data is 15.
The answers to other 2 question are there in the image attached.
