Mary has 20 liters of paint mixed white:blue in the ratio 2:3. So two fifths of that paint is white and three fifths is blue. So that's 8 liters white, 12 liters blue.
We want to add paint to get white:blue = 1:7. Clearly we need to add blue. We have our 8 liters of white, so we need a total of 7(8)=56 liters of blue. We already have 12, so we have to add 56-12=44 liters of blue paint:
Answer: Add 44 liters blue
The first choice because of rise over run and y-intercepts
Answer:
V= πr²h
V= 72π
V= 226.2
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a cylinder
Given data
Radius r of cylinder 3
Height h of cylinder 8
We know that the volume of a cylinder is given as
V= πr²h
Substituting our given data we have
V= π3²*8
V= π9*8
V= 72π
V= 226.2
Answer:
The x-intercept is 
The y-intercept is 
Step-by-step explanation:
Suppose you have a function f:
The x-intercept is the value of x when 
.
The x-intercept is the value of y when 
.
Solution
We have:
x-intercept
The x-intercept is the value of x when . So:
*(-1)
The x-intercept is
y-intercept
The y-intercept is the value of y when . So:
The y-intercept is
Answer:
divide 4. from 4 n 3. 3 divided by 4 answer us the answer fir x and then you times that answer to 4 and that is the answer for y
