Since we are given a point that lies on the line, the logical first step would be to plug that point in. If we plug that point in, we are left with no variables in the equation other than p. So:

5*2+p*4=22 \implies\\ 10+4p=22 \implies\\ 4p=12 \implies\\ p=3

Answer is F because the in order to find the area of the triangle you'd have to do 1/2×B×H and the slashes show that all four sides are congruent which means it's a square so 9.2×9.2=X.....Then you find the area of the rectangle which is 9.2×12=X add all those areas together and you should get 213.04ft2

A farm has sheep,pigs and cows at a ratio of 8:3:2. There are 10 cows, how many pigs and sheep are there
dedylja [7]

15 pigs and 40 sheep

10 cows is equivalent to 2 parts of the ratio, hence

\frac{10}{2} = 5 ← 1 part of the ratio, hence

8 parts = 8 × 5 = 40 ← number of sheep

3 parts = 3 × 5 = 15 ← number of pigs

Answer:

Volume= 82.4in³

Step-by-step explanation:

Volume is the measure of the amount of space inside of a solid figure, like a cube, ball, cylinder or pyramid. It's units are always "cubic"

To find the volume of sphere, we will use the following formula of Volume:

Volume = 4/3 πr³

Put the values in the formula:

As we know that the value of π is 22/7 or 3.14

Radius = 2.7

According to the formula:

Volume = 4/3 * 3.14 *(2.7)³

Volume= 4/3* 3.14(19.683)

Volume=4/3(61.80462)

Volume=247.21848/3

Volume= 82.4in³....
