Answer:
a. 90 degrees (given)
b. 270 degrees (360-90)
c. 16π (Circumference= diameter * π, diameter= 2r= 2(8)=16, so c= 16*π)
d. 4π (That section is a semicircle, so length should be 1/4 the circumference)
e. 12π (This section is 3/4 the circumference)
f. 64π (Area= πr^2, and r^2= 8^2= 64, so 64π)
g. 16π (That section is 1/4 the area)

Pocahontas wants to buy a tennis racket that is 70% off. The original price is $156.33. What is amount of discount (nearest penny)?
What is the sale price (nearest penny) please show your work
Answers
1. You could plug this into the calculator as either 70% of 156.33 or 0.7 × 156.33, but either way you know the discount is going to be $109.43
2. We got the discount, so all you have to do is subtract it from the original. 156.33 - 109.43 = $46.90 which is the sale price! I hope this helps

Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answers
Answer: y = -4x
Step-by-step explanation: You would use the formula y = mx + b to solve your problem. When you plug the numbers in, you get y = -4x. There would be no "+ b" because in this case, the y-intercept (b) is equal to zero. Therefore, you would not need to write "y = -4x + 0" because that would not be the equation in its simplest form.
Simplify each expression by using the distributive property and combining like terms.
3 ● (2x - 4) - 4x
Answers
Answer:
2x - 12
Step-by-step explanation:
Hello!
So, let's simplify using the distributive property.
Let's look at 3(2x - 4). You want to multiply 3 by every term inside the parentheses.
3*2x = 6x
3*-4= - 12
So now our expression looks like this:
(6x - 12) - 4x
Now we combine like terms. Our only like terms are 6x and -4x.
6x - 4x = 2x. So, our simplified expression is:
2x - 12.

Answer:
62.8
Step-by-step explanation:
the circumference is equal to the radiusx2xpi
it gives us the diameter but not the radius
to find the radius from the diameter we just divide it by 2 so the radius is 10
then we just do 10x2x3.14 which is 62.8
