A basketball player made 36 free throws in 16 games. Find the ratio of free throws to games.

andriy [413]

Any ratio simply takes the form (A/B)

Let throws = T , games = G

T = 36

G = 16

ratio of free throw to game = T/G

T/G = 36/16 = 9/4

10.) Your dad is planning to increase the area of your rectangular patio. Your current patio is 8

belka [17]

Answer:

x = 3.69 feet

11.69 x 13.69 feet

Step-by-step explanation:

new area = (8 x 10) x 2 = 160

(8 + x)(10 + x) = 160

80 + 8x + 10x + x² = 160

combine like terms:

x² + 18x - 80 = 0

factor:

(x - 3.69)(x + 21.69) = 0

x = 3.69

The number of volunteers to walk dogs at the local animal shelter last year was 20 this year the number of volunteers has risen

Alex73 [517]

There is 150% increase in the number of volunteers.

Step-by-step explanation:

Given,

Old number of volunteers = 20

New number of volunteers = 50

Change = New value - Old value

Change = 50 - 20 = +30

The positive sign indicates the increase.

Percent increase = $\frac{Change}{Old\ value}*100\\$

$Percent\ increase=\frac{30}{20}*100\\\\Percent\ increase=\frac{3000}{20}\\\\Percent\ increase=150\%$

There is 150% increase in the number of volunteers.
