Answer:
Part A: A ratio of 2:1 means that he uses<u><em> </em></u><u><em>2 cups of yellow paint for each cup of blue paint.</em></u>
-------------------------------------------------------------------------------------------------
Part B: The ratio of yellow to blue is 2:1 = 2/1. So, if for 2 yellow is 1 blue, then for 1 yellow is x:
2/1 = 1/x
x = (1*1) / 2
x = 1/2
<u><em>For each cup of yellow paint, Greg should add 1/2 cup of blue paint.</em></u>
<u><em></em></u>
-------------------------------------------------------------------------------------------------
Part C: 6 cups cost $54, then 1 cup cost:
54 / 6 = 9
<u><em>The price per cup of yellow paint is $9.</em></u>

First, break up the shapes into parts. The first one you see is 7 by 4 rectangle on the top.
A=l*w
A=7*4
A=28 for the rectangle, your not done
Now the triangle to the left
A=l*w/2
A=19*10/2
A=95
Now all you got left is the trapezoid, which area's formula is:
A=(b∧1+b∧2*h)/2
A=9+19*8/2
A=112.
Now you have the area for three of the figures, add them up:
112+95+28=235
So in total, the area of this figure is 235 cm^2
The value of 10^6 is going to be 1,000,000. because it is ten time itself 6 times. E.g 10*10*10*10*10*10
65. change 11 5/6 to a mixed number:
71/6-17/18
multiply 6 and 71 by 3 which equals 18 so now the denominators are the same
213/18-17/18=196/18
to simplify divide 196 and 18 by 2
196÷2=98
18÷2=9
now divide 98 by 9
98÷9=10 (rounded to whole number)
9×10=90
so to get 98 you add 8
your answer is 10 8/9
66. change both fractions to a mixed number
9 5/9=86/9
8 1/6=49/6
multiply 86 and 9 by 2
86×2=172
9×2=18
multiply 49 and 6 by 3
49×3=147
6×3=18
now subtract :
172/18-147/18=25/18
divide 25 by 18
25÷18=1 (rounded whole number)
18×1=18
to get 25 you add 7
your answer is 1 7/18
hope this helped
Answer:
We found the factors and prime factorization of 30 and 36. The biggest common factor number is the GCF number. So the greatest common factor 30 and 36 is 6.
