These triangles are similar. find Y and X
CaHeK987 [17]

It these triangles are similar, then the sides of the triangles are in proportion:

\dfrac{y}{10}=\dfrac{y+4}{15}      <em>cross multiply</em>

15y=10(y+4)    <em>use distributive property</em>

15y=10y+40       <em>subtract 10y from both sides</em>

5y=40           <em>divide both sides by 5</em>

\boxed{y=8}


\dfrac{x}{4}=\dfrac{6}{8}            <em>cross multiply</em>

8x=(4)(6)

8x=24           <em>divide both sides by 8</em>

\boxed{x=3}

Select the correct answer from each drop-down menu. The base of pyramid A is a rectangle with a length of 10 meters and a width
ASHA 777 [7]

Step-by-step explanation:

The formula of a volume of a pyramid:

V=\dfrac{1}{3}BH

B - base area

H - height

H - height of pyramids

Pyramid A:

B=(10)(2)=200\ m^2

V_A=\dfrac{1}{3}(200)H=\dfrac{200}{3}H\ m^3

Pyramid B:

B=10^2=100\ m^2

V_B=\dfraC{1}{3}(100)H=\dfrac{100}{3}H\ m^3

V_A>V_B\\\\V_A=2V_B

The volume of the pyramid A is twice as large as the volume of the pyramid B.

The new height of pyramid B: 2H

The new volume:

V_{B'}=\dfrac{1}{3}(100)(2H)=\dfrac{200}{3}H\ m^3

The volume of the pyramid A is equal to the volume of the pyramid B.
