Write a general formula to describe the variation: x varies jointly with the inverse of the sum of y and z.

A single microvillus is a rod-like structure that is 1.0 μm in height. it has a hemispherical top approximately 0.1 μm in diamet

andre [41]

The surface area of the cylinder that forms the "sides" of the microvillus rod is given by the area of the curved surface of a cylinder with diameter (d) = 0.1 μm and height (h) = <span>1.0 μm.

The curved surface area of a cylinder is given by 2πrh, where r = d / 2 = 0.1 / 2 = 0.05 </span><span>μm.

Thus, the curved surface area is given by

$2(3.14)(0.05)(1.0) = 3.14 \times 10^{-11}\mu m^2$

Therefore, </span>the surface area of the cylinder that forms the "sides" of the microvillus rod is $3.14 \times 10^{-11}\mu m^2$

maxine took out a loan for $3200 at 8% interest, compounded annually. if she makes yearly payments of $250, will she ever pay of

UkoKoshka [18]

Solution:

As per the problem

Maxine took out a loan for $3200 at 8% interest, compounded annually.

she makes yearly payments of $250.

she will be able to Payoff her loan iff yearly payments made is greater than yearly interest.

Interest payable in first year $=3200(1+0.08)-3200=3200*1.08-3200\\$

Interest payable in first year $=3456-3200=256$

This payable interest will goes on increasing year on year.

Hence Maxine will never payoff the loan.

In 2000 there were about 2,172,000 farms in the United States. Twenty -four thousand of the farms were in South Carolina. What p

Shalnov [3]

The amount of South Carolina Farms in the US is 24000/2172000
→ 24 000 ÷ 2 172 000 = 0.1104972
→ To convert into a percentage: 0.1104972 x 100 = 11.04972
→ Round 11.04972 to 11 (nearest whole percent)

∴ The percentage of farms in South Carolina is 11%

After a party you have 1/3 apple pie left and 5/6 pumpkin pie left. How much more pumpkin pie than apple pie is left?

motikmotik

There is 1/2 more pumpkin pie than apple pie left.

1/3 x 2 = 2/6

5/6 - 2/6 = 3/6

3/6 / 3 = 1/2
