Addition is needed because of the subtraction sign.
Answer:
r = √( s/4π)
Step-by-step explanation:
s = 4πr²
s/4π = 4πr²/4π
r² = s/4π
√(r²) =+/-√( s/4π)
r = √( s/4π) Because r is a radius of the circle , it should be positive.
Type A = $5.75 per pound
Type B = $4.55 per pound
1 set → 1 pound of Type A + 4 pounds of type B
1 set → 5.75 + 4(4.55)
1 set → $23.95
Number of sets = $526.90 ÷ 23.59 = 22
1 set → 1 pound of Type A
22 sets → 1 x 22 = 22 pounds of type A
Answer: 22 pounds of Type A
(4x - y)/(2y + x) = (4(3) - 3)/(2(3) + 3) = (12 - 3)/(6 + 3) = 9/9 = 1
Answer:
8/25
Step-by-step explanation:
We do this by multiplying the top first, and we get 32.
We then multiply the bottom, and get 100.
You might think the answer is 32/100.
Well, kind of! We need to simplify!
we divide the top and bottom by four to get our answer, 8/25.
