How many square feet of outdoor carpet will we need for this hole?

answer:

36 ft²

Step-by-step explanation:

First you find the area of the entire right triangle.

To do that use the formula A=bh/2

In this case b (base) is 7 ft and the h (height) is 12 ft.

So A = (7)(12) / 2

        = 84 / 2

        = 42

Next you find the area of that little rectangle shape that is cut out of the carpet.

To do that use the formula A=LW

In this case L (length) is 3 ft and the W (width) is 2 ft.

So A = (3)(2)

         = 6

Now because that rectangle is not part of the carpet, we subtract it from the area of the total shape, which is 42.

So 42 - 6 = 36

We will need 36 ft² of outdoor carpet for this hole.

answer:36

Step-by-step explanation:12 times 7 =84 divide by 2 =42-6=30

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
