The equation for the volume of a pyramid is (l*w*h)/3
 
 since the problem gave you the base area, that would be the l *w

so now you would need to multiply the base area by the height, then divide by 3

16 * 15 = 240

240/ = 80 cubic centimeters

8n-2(3n-3)=-2(-n-3) what is n<br> please show work
Galina-37 [17]

Answer:

0

Step-by-step explanation:

8n-2(3n-3)= -2(-n-3)

8n-6n+6=2n+6

2n+6=2n+6

2n=2n+6-6

2n=2n

Check

8(0)-2(3(0)-3)=-2(-0-3)

6=6

NEED HELP ASAP!
grigory [225]

Answer:

  5 minutes; 60 gallons

Step-by-step explanation:

The volume in tank A is initially 35 gallons. Its rate of change is 5 gallons per minute. The equation for volume can be written as ...

  y = 35 +5x . . . . . . where y is gallons, and x is minutes

The volume in tank B is initially 100 gallons. Its rate of change is -8 gallons per minute. The equation for volume can be written as ...

  y = 100 -8x

We want to find the values of x and y such that both are the same for both tanks.

  35 +5x = y = 100 -8x

  13x = 65 . . . . . . . . add 8x-65 to both sides of the equation

  x = 5

  y = 100 -8·5 = 60

Both tanks will hold 60 gallons after 5 minutes.

Find the average rate of change for the function f(x)=32 + 25
mixas84 [53]

given the function, there is no independent variable, x. Because of that your equation remains constant at the y axis, where you get f(x)=57. This means that for any input of x you’ll get 57 as the output. Because youre looking for average rate of change, you would use delta y/ delta x.

(2,57) and (6,57)

When you solve for change between the y and x, you get (57-57)/(6-2
) which ultimately gives you an average rate of change of 0.
