Pavel [41]

Hey There!

One of the numbers she might be thinking of could be 1,298, because it rounds to 1,300 in the nearest hundreds, and for the nearest tens. Remember, when a number is greater than 5 you round it to the nearest ten. Same rule applies for the hundreds, but the number has to be in the tens place instead of the ones place.

Suppose that y varies inversely with x and y = 3 when x=10 find y when x=5

zysi [14]

Answer:

y=1.5

Step-by-step explanation:

if (y = 3) is (x = 10) and (y = ?) is (x = 5) we see that x is half of the first equation in the second. This means we divide both variables in the first equation by half to get the second. [(x = 10) / 2 = (x = 5)] therefor, [(y = 3) / 2 = (y = 1.5)]. Making your answer 1.5.

Hope this helps :)

a beverage is made by mixing 3 parts of water with 5 parts of fruit juice how many parts of water are mixed with 1 part on fruit

Fittoniya [83]

Answer:

$\frac{3}{5}=0.6$

Step-by-step explanation:

Given the initial ratio of 3 parts water to 5 parts fruit juice, you can set up a proportion (equivalent ratios) to determine the amount of water needed with just 1 part of fruit juice:

$\frac{water}{fruit}=\frac{3}{5}=\frac{x}{1}$
