if y varies directly as the square root of x and y=87 when x=625, find y if x =390625. Round off your answer to the nearest hundredth

2175

Step-by-step explanation:

y = k sqrt(x)

x = 625

y = 87

87 = k * sqrt(625)

87 = k * 25

87/25 = k

k = 3.48

y = 3.48 * sqrt(390625)

y = 3.48 * 625

y = 2175

the answer is 37

step-by-step explanation:

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
