Answer:
90 balls
Step-by-step explanation:
Set up proportion
36/x = 40/100
Cross multiply: 40x=3600
Solve for x
x=90
To check work:
40 percent of 90 would be 36
90(0.4)=36
Answer:
$31250
Step-by-step explanation:
250×$125
=$31250
I think it’s 3 out of 5
Because 20-8 is 12
12 is the number of beans that is not blue
12/20 simply to 3/5
Hope it helps
To solve using completing square method we proceed as follows:
x^2-10x+8=0
x^2-10x=-8
but
c=(b/2)^2
c=(10/2)^2=25
thus we can add this in our expression to get
x^2-10x+25=8+25
factorizing the LHS we get:
(x-5)(x-5)=33
(x-5)^2=33
getting the square roots of both sides we have:
x-5=+/-√33
x=5+/-√33
15 ÷ 4 = 3.75
