Tree casts a shadow 30 feet long. A MHS student standing near the tree casts a shadow 9 feet long. The student is 6 feet tall. What is the height of the tree? Show all work

<em><u>Answer:</u></em>

Option D

The height of tree is 20 feet tall

<em><u>Solution:</u></em>

From given question,

Shadow of tree = 30 feet

Height of tree = ?

Height of student = 6 feet

Shadow of student = 9 feet

We have to find the height of tree

We can solve the sum by proportion

$\frac{\text{height of tree}}{\text{shadow of tree}} = \frac{\text{height of student}}{\text{shadow of tree}}$

This forms a proportion and we can solve the sum by cross multiplying

$\frac{\text{height of tree}}{30} = \frac{6}{9}\\\\\text{height of tree} = 30 \times \frac{6}{9} = 30 \times \frac{2}{3}\\\\\text{ height of tree } = 10 \times 2 = 20$

Thus height of tree is 20 feet tall

When c is increasing at a rate of 1.5×10?2 m?s?1 , how fast is b decreasing?

bearhunter [10]

The reaction is:
A ( g ) + 1/2 B ( g ) → C ( g )
We will rewrite it so the coefficient in the front of C is 1:
1/2 A + 1/4 B → C
So the rate of increasing of C is 4 times faster than the decrease of B.
The rate of B:
- 1.5 · 10^(-2) M/s : 4 = - 0.375 · 10^(-2) M/s = - 3.75 · 10 ^(-3) M/s
Answer: - 3.75 ·10^(-3) M/s
