Percentage decrease formula =
difference / original x 100%
95-74=21
21/95 x 100% = 22.1052632 ≈ 22.1 ( 3sf )
hope my answer helps
The goal is to find the radius of a circle which also helps to get the diameter. Finding the center helps to measure and know the circumference.
Answer:
y = x + 6
Step-by-step explanation:
y = x + b
when x = 0, y = 6. so....
6 = (0) + b
6 = b
so, y = x + 6
12) the radius is 15 so with the equation (3.14)*r^2, we get (3.14)(15^2)=706.5
13) true, true (if x=4), true
14) y=0.75x+4.50, $8.25
First set up a proportion
240/160 = 320/200
Cross multiply and if the left equals the right it is similar.
