Answer: 61% or exactly 60.9%
Step-by-step explanation:
if 34 are lifting weights then 53 (87-34) are not lifting weights and the percentage of 53/87 is 61%
We know that ratios can be shown with both fractions and colons.
20:705
or
It also looks like we can simplify this by dividing by 5.
20/5 = 4
705/5 = 141.
This means that for every 4 teachers, there are 141 students.
The ratio for teachers to students is:
4 : 141
Answer:
x = √2y^2 + 64 or x = √2y^2 + 64
Step-by-step explanation:
Solve for x.
x^2/64 - y^2/32 = 1
Step 1: Add 1/32 y^2 to both sides.
1/64 x^2 + -1/32 y^2 + 1/32 y^2 = 1 + 1/32 y^2
Step 2: Divide both sides by 1/64.
1/64 x^2/ 1/64 = 1/32 y^2 + 1/ 1/64
x^2 = 2y^2 + 64
Step 3:
x = √2y^2 + 64 or x = √2y^2 + 64
John made $40 commissions for $500 sales or 40/500. He wants $320 for an unknown amount of sales or 320/x.
40/500=320/x Cross multiply.
40x=160,000
Divide both sides by 40.
X=4,000
He needs his sales to be $4,000 to get $320 in commission.
