Which choice provides the most relevant detail?
aleksklad [387]

Option B, supplement and convert it into gas to use as fuel is the correct answer.

The best option is B because, compared to conventional yoghurt, Greek yoghurt demands up to four times as much milk to make. Greek yoghurt also generates more acid whey, that is challenging to dispose. During the production of yoghurt, a lot of gases are released along with the acid, which farmers have discovered can be utilized as a protein in livestock feed.

Additionally, scientists are attempting to reuse this acid. They are attempting to employ these pricey yet worthwhile conservation techniques. Nutritionists discuss Greek yogurt's advantages. As a result, choice B is correct.

What is the surface area of the sphere?
Fantom [35]

Answer:

<em>The surface area of the sphere is 314 mi².</em>

Step-by-step explanation:

According to the given diagram, the diameter of the sphere is 10 mi.

If the radius is r, then diameter =2r

So....

2r=10\\ \\ r=\frac{10}{2}= 5

<u>Formula for the surface area of a sphere</u>:  A_{S}= 4\pi r^2

Plugging the value of r into this formula, we will get...

A_{S}=4\pi(5)^2\\ \\ A_{S}=4\pi(25)\\ \\ A_{S}=4(3.14)(25)\ \ [Using\ \pi=3.14]\\ \\ A_{S}=314

So, the surface area of the sphere is 314 mi².

madam [21]

Answer:

5%

Step-by-step explanation:

Solving our equation

r = 4537.5 / ( 9075 × 10 ) = 0.05

r = 0.05

converting r decimal to a percentage

R = 0.05 * 100 = 5%/year
