Answer:
The radius of the balloon is increasing at a rate of 4 feet per minute.
Step-by-step explanation:
We are given the following in the question:
Volume of sphere is given by
where r is the radius of the balloon.
Instant radius, r = 2 ft
Rate of change of volume =
Putting values, we get,
Thus, the radius of the balloon is increasing at a rate of 4 feet per minute.
The mistake she made was timesing the 6 by the -7.5 as there is no x after the 6
Therefore:
-3.8(-7.5) +6
28.5+6 =34.5
Answer:
P = 28 cm
Step-by-step explanation:
The area of a square is
A = s^2 where s is the side length
49 = s^2
Taking the square root of each side
sqrt(49) = sqrt(s^2)
7 =s
Now find the perimeter of the square
P = 4s
P = 4(7)
P = 28 cm
Answer:
$0.22
Step-by-step explanation:
Now we know that 8 ounces total to $1.76. That means that in order to find how much 1 ounce costs, we will end up dividing both sides by 8
8 oz = $1.76
8 oz / 8 = $1.76 / 8
1 oz = $0.22
So, we now know that 1 oz is equal to 22 cents. You can also confirm your answer by multiple 0.22 by 8, and you'll see that you'll get 1.76
