Answer:
Height is 60 inches.
Step-by-step explanation:
The colored triangle that stands in the center of the pyramid is a right triangle. The side of the pyramid is 64, so the bottom edge of the colored triangle is 32. That 32 inch side is a leg of the right triangle. The other length given is the hypotenuse, 68 inches. We can use Pythagorean theorem.
x^2 + 32^2 = 68^2
x^2 + 1024 = 4624
x^2 = 4624 - 1024
x^2 = 3600
square root both sides.
x = 60

<em>4 cups of 75% fruit juice and 4 cups of 25% fruit juice should be mixed.</em>
Step-by-step explanation:
Suppose, the amount of 75% fruit juice is cups.
As the total amount of fruit punch is 8 cups, so the amount of 25% juice will be: cups.
Given that, the percentage of juice in 8 cups fruit punch is 50%
So, the equation will be.........
Thus, the amount of 75% fruit juice is 4 cups
and the amount of 25% fruit juice is (8-4)= 4 cups.
Answer:
B. an=8(3/4)^(n-1)
Step-by-step explanation:
The general term of a geometric sequence with first term a1 and common ratio r is ...
an = a1·r^(n-1)
The recursive rule for the sequence tells you the first term is 8 and the common ratio is 3/4. Then the explicit rule is ...
an = 8(3/4)^(n-1) . . . . . matches choice B
