A = 5/6B
A = 150.60
150.60 = 5/6B
150.60 / (5/6) = B
150.60 * 6/5 = B
903.60/5 = B
180.72 = B
180.72 - 150.60 = 30.12....u save 30.12 when buying from store A
Answer:
A) 125.6 inches
Step-by-step explanation:
1. The radius: As you said, it is half the diameter, so it is 40/2, which is <em>20 inches</em>.
2. Plug in numbers into the equation: r = 20 inches, π = 3.14
<em>C = 2 * 3.14 * 20 inches</em> (of course, it was unnecessary to find the radius when we already have the diameter, but this was done to fit the given equation)
Multiply: C = 125.6 inches
Easy peasy
just use PEMDAS and some exonential laws
also another is
![x^{\frac{m}{n}}=\sqrt[n]{x^{m}}](https://tex.z-dn.net/?f=%20x%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D%3D%5Csqrt%5Bn%5D%7Bx%5E%7Bm%7D%7D%20)
so

Hey there! :)
2r - 9 ≤ -6
To solve for r, we must move all variables to one side.
So, let's start out by adding 9 to both sides.
2r - 9 + 9 ≤ -6 + 9
Simplify.
2r ≤ 3
Divide both sides by 2.
2r ÷ r ≤ 3 ÷ 2
Simplify.
r ≤ 3/2
Simplify so that we don't have improper fractions.
r ≤ 1 1/2
Therefore, r is lesser than or equal to 1 1/2.
Using the process of elimination, we can see that the only answer choice that has r ≤ 1 1/2 in it is the THIRD answer choice.
~Hope I helped!~
