When answering questions like these, it helps to draw arrows,, the variable will always be on top, so in this situation you would draw an arrow from the a to the 10 and an arrow from the 38 to the 12 making them both fractions, you would then cross multiply, after cross multiplying you would get 12a=380 then you would divide by 12 equaling 31.6
Answer:
31.5 minutes
Step-by-step explanation:
21 / 2 = 10.5
10.5 x 3 = 31.5
Answer:
Step-by-step explanation:
add the whole numbers
combine the fractions
LCM is 35 because 7 * 5 =35
change the improper fraction into mixed number
False. In a two-column proof, the right column states your reasons.
Instantaneous rate of change = S'(r) = 8πr
S'(8) = 8π(8) = 64π
Therefore, the instantaneoud rate of change of the <span>surface area with respect to the radius r at r = 8</span> is 64π
