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

Answer:

Option D

The height of tree is 20 feet tall

Solution:

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

La suma de 5 números consecutivos es 122 cuáles son esos números ?

Answer:

1) 22.4

2) 23.4

3) 24.4

4) 25.4

5) 26.4

Step-by-step explanation:

La suma de 5 números consecutivos es 122 ¿cuáles son esos números?

5 números consecutivos se pueden representar como

1) = x

2) x + 1

3) x + 2

4) x + 3

5) x + 4

Por eso:

x + (x + 1) + (x + 2) + (x + 3) + (x + 4) = 122

x + x + 1 + x + 2 + x + 3 + x + 4 = 122

5x +10 = 122

5x = 122 - 10

5 veces = 112

x = 112/5

x = 22.4

5 números consecutivos se pueden representar como

1) x = 22.4

2) x + 1 = 22.4 + 1 = 23.4

3) x + 2 = 22.4 + 2 = 24.4

4) x + 3 = 22.4 + 3 = 25.4

5) x + 4 = 22.4 + 4 = 26.4

Answer:

P represents the population in year 0

Step-by-step explanation:

The exponential growth function is f(x) = a (1 + r)^t, where a is the initial

amount (at t = 0), (1 + r) is the factor of growth , r is the rate of growth

in decimal ant is the time of growth

the function C(t) = P(1 + r)^t represents the population of

centerville at year t, where P is the initial population and r is the

rate of increase

If your investment is increased 10% annually, then that means

each year, your total has multiplied itself by 110% (the growth factor

is 1 + 10/100 = 1.1)

(1 + r) is the factor grows each year

C(t) = P(1 + r)^t

C depends on P(starting population) , r(the increasing rate and

t(the time in year)

r is the rate of increase means the percentage of increasing , then

0 < r < 1

r is not less than 0

P is the initial amount when t = 0

P represents the population in year 0
