150 because 6 times 5 is 30 then you multiply whats inside the square root thing so you'd get 25, 25 is a perfect square which simplifies to 5 then 5 times 30 is 150.

Answer:

60%

Step-by-step explanation:

The original was $20 to $12, so if you divide both prices by 2 (to make one side 10 and the other the simplified percentage) you get:

10 to 6.

Percentages are typically x% out of 100, so if you multiply both by 10 you get:

100 to 60. All you have to do now is change the format to percentage instead of a fraction (60/100) and the answer is 60%.

Nina can ride her bike 63,360 feet in 3,400 seconds, and Sophia can ride her bike 10 miles in 1 hour. What is Nina’s rate in mil
luda_lava [24]

Step-by-step explanation:

So first off we want to find out how many miles Nina can ride in 3,600

For this we have to convert 63,360 feet into miles

If there are 5,280 feet in one mile than we need to see how many times 5,280 goes in to 63,360

divide 63,360 by 5,280: you get 12

This means that she can bike 12 miles in 3,600 seconds

3,600 seconds is the same as an hour

Answer:

Nina can bike 12 miles per hour

Answer:

See explanation

Step-by-step explanation:

Given that 9 cups of macaroni requires 27 cups of water

Therefore, 1 cup of macaroni will require 27/9 = 3 cups of water

Now i can help you to work out the correct way of filling the table;

If 1 cup of macaroni requires 3 cups of water

x cups of macaroni will require 9 cups of water

x = 9 *1/3

x = 3 cups of macaroni

If 1 cup of macaroni requires 3 cups of water

x cups of macaroni will require 33cups of water

x = 33 *1/3

x = 11 cups of macaroni

If 1 cup of macaroni requires 3 cups of water

x cups of macaroni will require 21 cups of water

x = 21 *1/3

x = 7 cups of macaroni

If 1 cup of macaroni requires 3 cups of water

x cups of macaroni will require 27 cups of water

x = 27 *1/3

x = 9 cups of macaroni

Use this to tick the table.
