Y=36
it basically says y=(9-3)^2
which is y=6^2
which is then y=36
Assuming that this happened at the same environment like the time of day, then we can use ratio and proportion. We relate the height of the tree with its shadow by using the ratio of the biologist's height to his shadow.
Height of tree/Height of its Shadow = Height of biologist/Height of his Shadow
Height of tree/28 = 7/2
Height of tree = 7*28/2
Height of tree = 98 feet
The answer is D.

Step-by-step explanation:
You're working with rates. It's relatively straight forward. Take miles per hour for instance. If you travel 60 miles in one hour, you're rate of speed is 60 miles per hour.
You haven't given any data in this example but the idea is the same. Let's say he transferred 10 songs in 5 minutes. That's means his rate is 10 songs per 5 minutes. You can change that to a fraction so it's easier to understand:

Now just reduce the fraction and it becomes

Also known as 2 songs per minute
Compound interest formula:
A = P(1+r/n)^nt
A ifs total amount
P = principal
r = interest rate
t = time
n = compound time
A = 2000(1+0.03/1)^4*1
A = $2,251.02
A.) height(h), diameter Sphere(d) = 14.6 in., diameter Cylinder (l) = 11 in.
d^2 = h^2 + l^2
h^2 = d^2 - l^2
h^2 = 14.6^2 - 11^2
h^2 = 213.16 - 121
h^2 = 92.16
h = 9.6 in.
b.) V = (4/3)(pi)(r^3)
r = d/2 = 14.6/2 = 7.3 in.
V = (4/3)(pi)(7.3^3)
V = 518.6893pi in^3
V = 1629.5106 in^3
V = 1629.51 in^3
