Answers

so ratio is there are 10 pairs of white socks and 21 pairs of socks total so the answer is
21:10
 You want the ratio of  (total pairs)  to  (white pairs) .

According to the data you gave in the question,
the ratio could be written as . . .

       21 : 10
or
       21 / 10
or
        2 and 1/10
or
        2.1    .

 

15 is 30% of what number?7 is what percent of 105?

And finally.. 1% of what number is 11?
Thanks

Answers

#1---> let the number you are trying to find be x for the following questions

30%*x=15
x=15/30%
x=50

#2
10%*x=14
x=14/10%
x=140

#3
(4/32)*100
 is the same as (1/8)*100= 12.5%

#4
1%* x=11
x=11/1%
x=1100

by the way * means multiply

Given:
Cylinder: radius = 8 yd; height = 4 yd
Surface Area = 2 π r h + 2 π r²
SA = 2 * 3.14 * 8 yd * 4yd + 2 * 3.14 * (8yd)²
SA = 200.96 yd² + 401.92 yd²
SA = 602.88 yd²
Volume = π r² h
V = 3.14 * (8yd)² * 4yd
V = 803.84 yd³

Dimension is cut in half. radius = 4yds ; height = 2yds
S.A = 2 * 3.14 * 4yd * 2yd + 2 * 3.14 * (4yd)²
S.A = 50.24 yd² + 100.48 yd²
SA = 150.72 yd²
V = 3.14 * (4yd)² * 2yd
V = 100.48 yd³

SA =
602.88 yd² - 150.72yd² = 452.16 yd²
V =
803.84 yd³ - 100.48 yd³ = 703.36 yd³

The quotient of 5/31 divided by 15/23, reduced to the lowest fraction, is A. 115/465.

 5/31 divided by 15/23 is 5/31 times 23/15
it means that the answer is 
B. 23/93. 

Find the constant of variation k for inverse variation. Then write an equation for the inverse variation. y= 5 when x = 7.5 k = 37.5;y = 37.5/x k = 15;xy = 1.5 k = 2.5;y = 2.5/x k = 37.5;y=37.5x

Answers

direct variation has this formula: y = kx
inverse variation has this formula: y = k/x

y = 5 ; x = 7.5 ; k = 37.5

y = k/x ⇒ 5 = 37.5 / 7.5 ⇒ y = 37.5/x

Answer:k=37.5 ; xy=37.5
