Answer: 30 degrees, 60 degrees and 90 degrees

If one exterior angle is 120, then its interior counterpart is 180-120 = 60.

If another exterior angle is 150, then is interior counterpart is 180-150 = 30

Let x be the missing interior angle. It adds with the other interior angles and all three interior angles of any triangle always add to 180

x+60+30 = 180

x+90 = 180

x+90-90 = 180-90 .... subtract 90 from both sides

x = 90

So the missing interior angle is 90 degrees

Not exactly sure if I’m right but

1. $56 < $60



2. $60 - $36 = $24/4 hours = 6.

36+24 = 60, we want to use LESS than 60 so we use see how much it’ll take to spend 5 hours for parking.

5 x $4 = $20.

$36 + $20 = $56


I’m not exactly sure though...

cluponka [151]

Answer: We need to mix 18 quarts of sparkling water with 9 quarts of grape juice.

We need to mix 1.875 quarts of grape juice with 3.75 quarts of sparkling water.

Step-by-step explanation:

Given: A recipe for sparkling grape juice calls for 1.5 quarts of sparkling water and .75 quart of grape juice.

Since, for recipe of sparkling grape juice , they should be used in same proportion.

Let x be the amount of sparkling water need to mix with 9 quarts of grape juice, then

\frac{x}{9}=\frac{1.5}{0.75}\\\Rightarrow\ x=\frac{1.5\times9}{0.75}\\\Rightarrow\ x=18

We need to mix 18 quarts of sparkling water with 9 quarts of grape juice.

Let y be the amount of grape juice need to mix with 3.75 quarts of sparkling water, then

\frac{3.75}{y}=\frac{1.5}{0.75}\\\Rightarrow\ y=\frac{3.75\times0.75}{1.5}\\\Rightarrow\ y=1.875

We need to mix 1.875 quarts of grape juice with 3.75 quarts of sparkling water.

Step-by-step explanation:

we know that

To find out the area of the sidewalk, multiply the length by the width of the sidewalk

The width of the sidewalk is equal to

113.4\ ft-110\ ft=3.4\ ft

or

75.4\ ft-72\ ft=3.4\ ft

The area is equal to

113.4(3.4)+72(3.4)\\385.56+244.8\\630.36\ ft^2
