-5,-6 is the answer it is x than y
59 of the post cards were from the United states. Just subtract 24 from 83
You will need to know that the sum of "two complementary angles" is 90
therefore
Let x = one angle
then
90-x = second angle
.
Now, we construct our equation based on the sentence:
"The sum of the measures of two complementary angles exceeds the difference of their measures by 86°."
x + 90-x = x-(90-x)+86
90 = x-90+x+86
90 = 2x-90+86
90 = 2x-4
94 = 2x
47 degrees = x (first angle)
.
Second angle:
90-x = 90-47 = 43 degrees (second angle) hope it helps
Answer:
the pile has a height H = 15.09 ft
Step-by-step explanation:
The volume of a cone V is
V= 1/3*π*H*R²
where H= height , R=radius
if the diameter D=2*R is 3 times its height
D=3*H → 2*R=3*H → R=3/2*H
then
V= 1/3*π*H*R² = 1/3*π*H*(3/2*H)² = 1/3*π*H*9/4*H² = 1/12*π*H³
V= 1/12*π*H³
if the volume is V=900 ft³ , then solving for H
V= 1/12*π*H³
H = ∛(12*V/π) = ∛(12*900 ft³/π) = 15.09 ft
H = 15.09 ft
then the pile has a height H = 15.09 ft
