An electrical tower casts a 120-foot shadow. At the same time, a 10-footstreet sign casts a shadow of 8 feet. What is the height of the tower?

Answers

Answer 1

Answer:

Answer:

The height of the tower is 150 ft

Step-by-step explanation:

Let the height of the tower be H feet.

The corresponding sides will then be in the same proportion.

The ratio of the shadows will be in the same proportion as the ratio of the heights.

$(H)/(10)=(120)/(8)$

We multiply both sides by 10 to get:

$(H)/(10)* 10=(120)/(8)* 10$

$H=150$

Therefore, the height of the tower is 150 ft

Answer 2

Answer:

Answer:

Height of the tower = 150 foot

Step-by-step explanation:

We need to find height of the tower with 120-foot shadow.

We have a 10-foot street sign casts a shadow of 8 feet.

$\texttt{Ratio of height to shadow height =}(10)/(8)=(5)/(4)$

We have

$\frac{\texttt{Height of tower}}{\texttt{Shadow height of tower}}=(5)/(4)\n\n\frac{\texttt{Height of tower}}{120}=(5)/(4)\n\n\texttt{Height of tower}=(5)/(4)* 120=150feet$

Height of the tower = 150 foot

Can the sum of two mixed numbers be equal to 2? explain why or why not.

Answers

no it cannot because a mixed # for example would look like this 2 3/5 it will need a whole number and a fraction
The reason why I say NO is because you can only have 1 mixed number in 2 and that would be 1 1/2 (1 1/2 + 1/2 = 2) And when you try again your numbers will be 1 and 1. So NO, you cannot have to mixed numbers in the number 2
