Determine whether the variation between the indicated quantities is direct or inverse. The number of calories in a cheese pizza

-BARSIC- [3]

Answer:

The variance is direct.

Step-by-step explanation:

Since size of the pizza determines the amount of calories.

Let us say that a 2" x4" strip of pizza has 250 calories.

Then a pizza of twice the size (or 4" x 4") will have twice as many calories (500 calories) .

For the right triangle shown, the lengths of two sides are given. find the third side. leave your answer in simplified, radical

lisov135 [29]

If c is the hypotenuse and b is the leg, then the third side (a):
$a= \sqrt{c^2-b^2}= \sqrt{16^2-9^2}= \sqrt{256-81}= \sqrt{175}=5 \sqrt{7}$

If b and с are legs, then hypotenuse (a):
$a= \sqrt{b^2+c^2}= \sqrt{9^2+16^2}= \sqrt{81+256}= \sqrt{337}$

Find the total surface area

Sindrei [870]

Answer:

298 cm^2.

Step-by-step explanation:

There are 3 pairs of faces of equal area.

Area of top = 7 * 11. So it's 2 * 7 * 11 = 154.

Area of a smaller side = 7 * 4 so we have 2*28 = 56 .

Area of larger side = 4*11 so it's 2*44 = 88.

Total surface area = 154 + 56 + 88

= 298.
