(length of tree's shadow)/(height of tree) = (length of person's shadow)/(person's height)
24/x = 8/5
24*5 = x*8
120 = 8x
8x = 120
8x/8 = 120/8
x = 15
The tree is 15 feet tall
Answer
(a)

(b)

Step-by-step explanation:
Remember that when you want to solve a problem like this, you express the equation as following

So, if you know the inverse of
then

For this case

Now for this case the inverse of A would be

Then when you multiply with the vector solution

So from that information you can conclude that the solution to the system of equations is x = 500/7 y = 2400/7 and z = 2700/7
Step-by-step explanation:
35x׳/7 = (35x×⅕)+(35x×1/x)
15x=7x+35
8x=35
x=4.375.
hope this helps you.
Answer:
<
Step-by-step explanation:

by dividing both sides by the same number, let's say c, then

you got a 87.5% B
(divide what you got by how many points possible)
hope that helps :)
