Answer: the ratio of gallons of blue paint to gallons of yellow paint that will make the same shade of green is 5/9
Step-by-step explanation:
The housepainter mixed 5 gallons of blue paint with every 9 gallons of yellow paint in order to make a green paint.
To determine the ratio of gallons of blue paint to gallons of yellow paint that will make the same shade of green, we will divide the gallons on blue paint required by the gallons of yellow paint required. It becomes
The ratio is 5/9 = 5:9
It means that for every 5 gallons of blue paint, 9 gallons of of yellow paint is required
Answer:
11
Step-by-step explanation:
First, write an equation to represent the situation.
34 = 2a + 12
This equation works because your combined age is half of 68, so 34. If your age is a, then yours sister's age is a + 12. if you add your age to your sister's, you get 2a + 12.
Now just solve for a.
34 = 2a + 12
First, subtract 12 from both sides.
22 = 2a
Then divide both sides by 2.
11 = a
So you are 11 years old. If you need to check your work, your age (11) plus your sister's age (11 + 12, which is 23) is 34, which is half of your grandfather's age.
Answer:
Step-by-step explanation:
<3 = 55° ( vertically opposite angles )
<4 = 180 - 105 = 75° ( linear pair )
<5 = 180 - ( 55 + 75 ) ( angle sum property of a triangle )
= 180 - 130
= 50°
<1 = <2 ( angles opposite to equal sides )
let < 1 and < 2 be x
55 + 2x = 180 ( angle sum property of a triangle )
2x = 180 - 55
2x = 125
x = 125 / 2
x = 62.5
therefore, < 1 = <2 = 62.5°
