$ 9.5

Step-by-step explanation:

total money is $20

on lunch = 1/8 × 20 = 5/2 = $2.5

on movies = 2/5 × 20 = $8

total spent = 2.5+8 =$ 10.5

Does anyone know how to do 7a?

Calculate the circumference of the two semi circles, which equals a full circle. Then add the two sides of the track.
 Circumference is pi x diameter = 3.14 x 22.8 = 71.592, so, you would need to add 71.592 + 49.2 + 49.2  = 169.992 meters, and that would be the length of one lap of the track.

One side of a triangle is 2 times the second side. The third side is 5 ft longer than the second side. The perimeter of a triang
TiliK225 [7]

Answer:

The length of each side of triangle are 19 ft, 24 ft and 38 ft.

Step-by-step explanation:

Let the length of second side be x.

Now given:

Length of first side is 2 times length of second side.

Length of first side = 2x

Also, Length of third side is 5 ft longer than the second side.

Length of third side = 5+x

Perimeter of triangle = 81 ft.

We need to find the length of each side.

Now perimeter of triangle is sum of all three sides of triangle.

Therefore;

Perimeter of triangle =  Length of first side + length of second side + Length of third side.

2x+x+5+x=81 ft\\4x+5=81ft\\4x= 81 -5 ft\\4x = 76ft\\x= \frac{76}{4} = 19 ft

Length of Second Side = 19 ft.

Length of First side = 2x= 2\times19 = 38 ft

Length of Third side = 5+x= 5+19=24ft

Hence the Length of triangles are 19 ft,38 ft,24 ft.
