Answer:

<h2>The second pyramid, placed in the middle, has a volume of 15 square units.</h2>

Step-by-step explanation:

Givens

  • The area of the bases is 15 square units.
  • All of them have the same base.

The volum of a pyramid is defined as

V=\frac{1}{3}Bh

WhereB is the are of the base and h is the height.

So, all of them have B=15u^{2}

The first pyramid has a height of 4, replacing this in the formula we have

V=\frac{1}{3}15(4)=5(4)=20u^{3}

The second pyramid has a height of 3

V=\frac{1}{3}15(3)=5(3)=15u^{3}

The third pyramid has a height of 12

V=\frac{1}{3}15(12)=5(12)=60u^{3}

Therefore, the second pyramid, placed in the middle, has a volume of 15 square units.

drek231 [11]

Answer:

60

Step-by-step explanation:

We use unit rate function,

Let h be hours

Let b be baskets

2.5h = 150b

We divide both sides by 2.5

2.5h/2.5 = 150b/2.5

Which will give us

h = 60

4) a. x+y=1–(1)
y=2x-8—(2)
(2) into (1)
x+(2x-8)=1
3x-8=1
3x=1+8
x=9/3
x=3—(3)
(3) into (2)
y=2(3)-8
y=-2

ans x=3, y=-2

b. x+y=19—(1)
y=5x+1—(2)

(2) into (1)

x+(5x+1)=19
6x+1=19
6x=19-1
x=18/6
x=3—(3)

(3) into (2)

y=5(3)+1
y=16

ans x=3, y=16

c.x+y=-2—(1)
y=x-10—(2)

(2) into (1)

x+(x-10)=-2
2x-10=-2
2x=-2+10
