x = 13/0.20
x = 65 <== original price
Answer:
471.3inches
Step-by-step explanation:
Given data
Diameter= 30in
Radius= D/2= 30/2= 15in
The circumference is the same as the distance covered in one revolution
C= 2πr
Hence the distance covered in 5 revolutions is
C= 2*5*πr
Substitute
C=10*3.142*15
C= 471.3inches
Answer:
1/7
Step-by-step explanation:
Lets start with the probability of flipping tails, 1/2.
Then the probability of the day starting with the letter s, 2/7.
Calculate the final probability by multiplying the two together.
![\frac{1}{2}*\frac{2}{7}=\frac{2}{14}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%2A%5Cfrac%7B2%7D%7B7%7D%3D%5Cfrac%7B2%7D%7B14%7D)
You can simplify 2/14 down to 1/7
We can use the points (-2, -5) and (18, -5) to solve.
Slope formula: y2-y1/x2-x1
= -5-(-5)/18-(-2)
= 0/20
= 0
Best of Luck!
