Answer:
They should use <u>1.2 gallons</u> of yellow paint.
Step-by-step explanation:
Given:
Julia and Rasheed are mixing yellow paint and blue paint to make green paint.
The mixture needs to be 60% blue paint and 40% yellow paint.
They need to make 3 gallons of the green paint.
Now, to find the quantity of yellow paint they should use.
As,
60% + 40% = 100%
So, we get the ratio of blue paint to yellow paint:
= 
= 
= 
Thus, the ratio of blue paint : yellow paint is 3:2.
<em>They need to make total 3 gallons of green paint.</em>
Now, to get the quantity of yellow paint:
Therefore, they should use 1.2 gallons of yellow paint.
Answer:
62.5
Step-by-step explanation:
x=ky^3
2=k1^3
2=k1
k=1/2
x=1/2×5^3
x=1/2×125
x=62.5
X=1.3
Hope this helps I not I’m truly sorry
Answer:
The first side is 11.5cm, the second is 11.5cm×2 = 23cm, the third is 11.5cm × 3 = 34.5cm,
and the fourth side is 11.5cm × 6 = 69cm.
Step-by-step explanation:
A quadrilateral is a 4 sided shape, while perimeter is the addition of all the sides of the quadrilateral. Since the sides of the quadrilateral is not stade, assume the sides of the quadrilateral is x, therefore 1:2:3:6 = x:2x:3x:6x. The total ratio is x+2x+3x+6x=12x, therefore 12x= 138 , x = 11.5cm, Therefore the first side is 11.5cm, the second is 11.5cm×2 = 23cm, the third is 11.5cm × 3 = 34.5cm, and the fourth is 11.5cm × 6 = 69cm.
Answer:
Set one: 12 and 13
Set two: -13 and - 12
Step-by-step explanation:
Let the smaller number = x
Let the larger number = x + 1
x^2 + (x + 1)^2 = 313 Remove the brackets on the left.
x^2 + (x^2 + 2x + 1) = 313
x^2 + x^2 + 2x + 1 = 313 Collect like terms
2x^2 + 2x + 1 = 313 Subtract 313 from both sides
2x^2 + 2x + 1 - 313 = 313 - 313
2x^2 + 2x - 312 = 0 Divide by 2
x^2 + x - 156 = 0
factor
There are two sets of factors that work
Set One
x = 12
x + 1 = 13
Set Two
x = - 13
x+1 = -13 + 1 = - 12
The second set is where you will get your marks. Few people will remember to use the minus answer
