Its the 3, 4, 5 Pythagorean Triple so it would be D 8 inches
Answer:
she would be playing for 42 minutes
Step-by-step explanation:
times how many songs by how long it takes to play them --- 6 times 7= 42 min!
When something varies directly as something else, their ratio of change always stays the same.
56 / 7 = 8
Therefore,
8 * 3 = 24
If x = 3 then y = 24
Boys : Girls = 2:7
let the no. of boys be x
so no of girls = 250+x
so, x:(250+x) = 2:7
x/(250+x) = 2/7
7x = 500+2x
7x-2x = 500
x = 500/5 =100
