Answer:
D. 14.73
Step-by-step explanation:
According to Pythagoras,
19^2 = 12^2 + x^2
x^2 = 19^2 - 12^2
x^2 = 361 - 144
x^2 = 217
x = 
x = 14.73
Answer:
1. 24 quarts. 2. 85 seconds.
Step-by-step explanation:
1. We need to know how many 2/3 are in 4.
if 3/3 are in 1 cup, then 12/3 are in 4 cups.
there are 6 twos in 12, so there are 6*2/3 cups in 4 cups.
Each 2/3 needs 4 quarts of green, and we have six times that.
6*4 = 24, so we need 24 quarts of green paint.
2. The 12.75 miles would go in the "d" or distance part of the equation.
d = 0.15t
12.75 = 0.15t (divide both sides by 0.15)
12.75/0.15 = 0.15t/0.15
t = 85, so 85 seconds.
12.75 miles isn't the distance between the two cities, it's much farther, so this answer makes sense.
Answer:
<H = 40
Step-by-step explanation:
Complementary angles add to 90 degrees
2x+10 + x+20 = 90
Combine like terms
3x+30 = 90
Subtract 30
3x+30 -30 = 90-30
3x = 60
Divide by 3
3x/3 = 60/3
x = 20
<H = x+20 = 20+20 = 40
