Find the volume of a sphere that has a surface area of 16 * pi sq. in.
Thepotemich [5.8K]
You can use this formula to solve this problem... it uses the surface area to find the volume.

V= (A^3/2)/(6√pi)   

Substitute the surface area value into "A" and then solve as you would on paper. I'm sorry I couldn't show you the entire process but this should get you your answer. Plus if your teacher asks for work, I just set you up and everything else should be self explanatory.  

But the answer is ---->  33.5 inches cubed

Calculate 3n-1 for n equals 2 to 10 explain how you know that the numbers are composite
Troyanec [42]

composite number means a number that can be formed by multiplying two smaller numbers

3n-1 for n=2, 3n-1=3*2-1=6-1=5

3n-1 for n=10, 3n-1=3*10-1=30-1=29

5 is composite because 2*2.5=5

29 is composite because 5*5.8=29

Lena has 2 boxes of buttons A and B.In total are 1.200 buttons .She move 360 buttons from box A to B.There are now 3 times as ma
Fittoniya [83]

Answer:

660

Step-by-step explanation:

Let  A = number of buttons in Box A

and B = number of buttons in Box B

We have two conditions:

(1)            A + B = 1200

(2)       B + 360 = 3(A – 360)     Remove parentheses

          B + 360 = 3A - 1080      Subtract 360 from each side

(3)                 B = 3A - 1440       Substitute (3) into (1)

A + 3A - 1440 = 1200               Combine like terms

      4A - 1440 = 1200               Add 1440 to each side

                4A  = 2640               Divide each side by 4

                   A = 660

Using the following conversions between the metric and U.S. systems, convert the measurement. Round your answer to 6 decimal pla
valina [46]

Answer:

  23,128.56 qt

Step-by-step explanation:

We need to add the conversion from L to qt:

  1 L = 0.26 gal = 0.26(4 qt) = 1.04 qt

Multiplying by 22239 L, we have ...

  22,239 L = 23,128.56 qt

_____

<em>Comment on the answer</em>

The conversion factor given is good for 2 significant digits, so the answer would be appropriately rounded to 23,000 qt. The real conversion is to 23,496.519025 quarts when rounded to 6 decimal places.
