What is the slope of the line?
Answer:
1/2
Step-by-step explanation:
y = mx + b is slope intercept form.
b = y intercept. where the line first passes through on the y axis
that number is 3.
y = mx + 3.
to find M (slope) you have to do RISE / RUN.
Run is going left or right from a point
Rise is going up or down from a point.
To make sure you find the slope, when you Rise and Run, it has to hit another point on the graph.
From the y - intercept 3, RISE (go up) 1 and RUN (go left) 2.
So, the slope is 1/2.

The height of a cylinder is 8 centimeters. The circumference of the base of the cylinder is 20π centimeters. Which measurement is closest to the volume of the cylinder in cubic centimeters?
Answer: [tex]2514.28\ cm^3[/tex]
Step-by-step explanation:
Given
The height of the cylinder is [tex]h=8\ cm[/tex]
Circumference of the base is [tex]20\pi \ cm[/tex]
suppose 'r' is the radius of the cylinder
[tex]\Rightarrow 2\pi r=20\pi\\\Rightarrow r=10\ cm[/tex]
The volume of a cylinder is [tex]V=\pi r^2h[/tex]
[tex]\Rightarrow V=\pi \times 10^2\times 8=2514.28\ cm^3[/tex]

Michelle and Natasha each had to repair their new iPhones. The initial cost of each repair is $100. Michelle and Natasha each have two discount coupons. Each of them uses both coupons toward the cost of the repair. One coupon is for $25 off the repair cost and the other coupon is for 20% off the repair cost. Michelle and Natasha use their coupons in a different order, as shown below.
Michelle uses the 20% off the repair cost coupon first. She then uses the $25 off the repair cost coupon on the remaining balance.
Natasha uses the $25 off the repair cost coupon first. She then uses the 20% off the repair cost coupon on the remaining balance.
Who paid the least amount of money for the iPhone repair?
Answer:
natasha paid the least amount

Find the surface area of this prism.
Round to the nearest tenth.
Answer:
The answer is 493.3
Step-by-step explanation:
6.72 x 12.7 x 5.78 = 493.28872
And 493.28872 rounded to the nearest tenth is 493.3 because the original number in the tenth place is 2 and then the digit before that is 8 which in this case is your rounding digit. Round up If the number is greater than 5 and round down if its less than 5. In this case its greater than 5 to that leaves you with 28 so now you have 493.28, 28 rounded to the nearest tenth is 30 and just take the 0 away, as if it didn't exist.
The surface area of the prism is 395 square centimeter.
What is volume?Volume is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write volume as -
V = ∫∫∫ F(x, y, z) dx dy dz
Given is to fins the surface area of the prism given below.
The given prism is a cuboid. We can write the surface area of the cuboid as -
V = 2(LB + BH + LH)
V = 2(12.7 x 5.78 + 5.78 x 6.72 + 12.7 x 6.72)
V = 2(73.4 + 38.8 + 85.344)
V = 395 square centimeter
Therefore, the surface area of the prism is 395 square centimeter.

The company charges $45 a day for the car
as well as charging a one-time $25 fee for
the car’s navigation system (GPS). Write an
equation for the cost in dollars, C, as a
function of the number of days, d, the car
was rented.
Answer:
I personally find it easier to put my equation in words before actually writing the equation, so for this particular situation, the equation would sound like this :
→ The cost (C) is equal to 45$ a day (d) plus 25$!
Now that your equation is put into words, all that you have to do is write down the equation without the words :
→ C = (45d) + 25
If you want to make sure that your equation is correct, you can try it out, say for instance you want to rent a car for a week, so for a total of 7 days, and you want to see how much it would cost :
d = 7 (in this particular situation)
C = (45 × 7) +25
↓
C = 315 + 25
↓
C = 340
→ So it would cost 340$ to rent a car for a week!
