The two horizontal lines are parallel, so the smaller triangle is similar to the entire triangle.

That means the sides are proportional to each other. So pick two sides of the triangle and find the ratio between them. The ratio must be the same for both triangles.

(15/5) = (15+x)/8

Solve for x.

15*8 = 5(15+x)

120 = 75 + 5x

5x = 45

x = 9

Sub in the values and solve for W
50=3W+14
50-14=3W
36=3W
12=W
The team won 12 games.
12+14=26 (games drawn and won)
35-26=9
Therefore they lost 9 games

Big Bob’s Pizza is having a special on pizza and is offering two different choices:

Anna71 [15]

Answer:

The Choice N#1 will give more pizza for your money

Step-by-step explanation:

step 1

Find the area of one slice Choice #1

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=22/2=11\ in$ ----> the radius is half the diameter

assume

$\pi =3.14$

The area of one slice is equal to

$A=(1/8)\pi r^{2}$

substitute

$A=(1/8)(3.14)(11)^{2}$

$A=47.4925\ in^{2}$

Divide the cost by the area

$4.95/47.4925=0.10\frac{\$}{in^{2}}$

step 2

Find the area of the entire personal pizza Choice # 2

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=6/2=3\ in$ ----> the radius is half the diameter

assume

$\pi =3.14$

substitute

$A=(3.14)(3)^{2}$

$A=28.26\ in^{2}$

Divide the cost by the area

$3.75/28.26=0.13\frac{\$}{in^{2}}$

therefore

The Choice N#1 will give more pizza for your money
