For every 1 cup of red paint, cup of blue paint is needed
For every 4 cups of red paint, cups of blue paint are needed
<em><u>Solution:</u></em>
Given that, there are 3 1/3 red cups of paint for every 1 1/3 cups of blue paint
Therefore, ratio is
Let "x" be the cups of red paint needed
Then we get,
This forms a proportion
Therefore, 10/4 cups of red are needed for 1 cup of blue
<h3><u>For every 1 cup of red paint, ___ cup of blue paint is needed</u></h3>Let "x" be the cups of blue paint needed
Then, we get
This forms a proportion
Thus, 4/10 cups of blue are needed for 1 cup of red paint
<h3><u>For every 4 cups of red paint,___ cups of blue paint are needed</u></h3>Let "x" be the cups of blue paint needed
Then, we get
This forms a proportion
Thus 16/10 cups of blue paint are needed for every 4 cups of red paint
Answer:
Step-by-step explanation:
The standard form of a circle's equation is
where h and k are the circle's center and r is the radius. We are told, and we can see, that the center of the circle is (0, 0) so h = 0 and k = 0. The radius, given as 4, goes into the equation squared, so the equation is
which simplifies down to
, choice C.
