What is the answer to m

Answer:

Height of a cell tower is, 30 m

Step-by-step explanation:

Proportion states that the two fractions or ratios are equal.

As per the given statement:

Let height of a cell tower be h.

Height of a pole = 3m ,

Shadow of a pole = 4 m and

shadow of a cell tower = 36+4 = 40 m

By definition of proportion;

$\frac{\text{Height of a cell tower}}{\text{Shadow of a cell tower}} = \frac{\text{Height of a pole}}{\text{Shadow of a pole}}$

Substitute the given values we get;

$\frac{h}{40}=\frac{3}{4}$

by cross multiply we get;

$4h = 120$

Divide both sides by 4 we get;

h = 30 m

Therefore, the height of a cell tower is, 30 m

Hello! We know that we have $400. So 23 ten dollar bills is equal to $230. How? We multiply 23 x 10 and get $230. Then, we have 46 dimes. A dime is worth 10 cents so we multiply 46 x 10 which equals $4.60. And of course we have the 19 cents. Now we add. 400 + 230 + 4.60 + 19 = $653.6.

Hope this Helps!
