Answer: $5
Step-by-step explanation:
For every $3 raised by basketball players, football players would raise $2.50.
If basketball players raised $6 therefore, we can use direct proportion to find out what football players raised:
3 : 2.50
6 : x
Cross multiply:
3x = 15
x = 15 / 3
x = 5
Football players raised $5.
P of triangle = a + b = c = 90
<span>ratio 3:4:5
so a = 3x, b = 4x , c = 5x
3x + 4x + 5x = 90
12x = 90
x = 90/12 = 7.5
a = 3x = 3 * 7.5 = 22.5
b = 4x = 4 * 7.5 = 30
c = 5x = 5 * 7.5 = 37.5
Answer:
1st side = 22.5
2nd side = 30
3rd side = 37.5
Double check: 22.5 + 30 + 37.5 = 90 (perimeter)</span>
A all squares have the sides
