A sphere is partially filled with air. If the volume of the sphere is increasing at a rate of 548 cubic feet per second, what is
Rama09 [41]

Answer:

  137/(36π) ft/s

Step-by-step explanation:

The rate of change of volume will be the product of the rate of change of radius and the area of the sphere. The area of the sphere is ...

  A = 4πr² = 4π(6 ft)² = 144π ft²

Then the relationship above is ...

  dV/dt = A·dr/dt

  548 ft³/s = (144π ft²)·dr/dt

  dr/dt = (548 ft³/s)/(144π ft²) = 137/(36π) ft/s ≈ 1.2113 ft/s

Galina-37 [17]
<span>c. 4.6
       
21 X .22= 4.6
       
Calculating the variance requires finding the product of 21 and 22%. To make this easier we convert 22% into it's decimal form and construct the equation. To back check this answer we can use 10% of 21 voters which equals 2.1% then double that amount to reach 4.2%, knowing that we now have a close approximation of the variance we can eliminate answers a, b, and d, leaving c as the only logical choice.</span>

What is the value for y?<br> Enter your answer in the box.<br> y=
serious [3.7K]

Answer:

y =112

Step-by-step explanation:

Given

The attached triangle

Required

Find y

The attached triangle is isosceles; so:

x - 5=34

Also, we have:

y + x - 5 + 34=180 --- angles in a triangle

Substitute: x - 5=34

y + 34 + 34=180

Collect like terms

y =- 34 - 34+180

y =112
