I HAVE 10 MIN PLS HELP FIND THE VOLUME

900

Step-by-step explanation:

The figure is a triangular prism

The equation would be V = A * H / 3

V being the volume

A being the area of the pyramids base

H being the height front he base to the top  (20)

Base area is 135 (A)

135 * 20 = 2700

2700 divided by 3 = 900

900 is your answer

1 is c

2 is a

3 is a

step-by-step explanation:

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)
