A 12 feet tall street light is making an 18 feet shadow at the same time in nearby building is making a 72 feet shadow

Harman [31]

Answer: 48 ft

Step-by-step explanation:

Given

Height of street light h=12 ft

length of shadow x=18 ft

Shadow length of building x'=72 ft

suppose the height of the building is y

from the figure, we can write

$\Rightarrow \tan p=\dfrac{h}{x}=\dfrac{12}{18}\\\\\Rightarrow \tan p=\dfrac{y}{x'}=\dfrac{12}{18}\\\\\Rightarrow y=72\times \dfrac{2}{3}=48\ ft$

Evaluate the following expression 2x - |4 - 7x| when x = -3

HACTEHA [7]

Answer:

-31

Step-by-step explanation:

2x - abs(4 - 7x)

2x = 2 * - 3 = - 6

4 - 7x = 4 - 7*-3 = 4 + 21 = 25

-6 - abs(25)

-6 - 25 = -31

You should note three things.

1. the absolute value of 25 is 25

2. There is a - sign outside the influence of the 25 so 25 becomes - 25

3. - 6 - 25 = - 31

The statements with their relation to 0 are:

Oliver owes his sister $27. $\to$ -27
A building is 38 feet tall. $\to$ 27
Erica jumped 2.7 feet above ground. $\to$ 2.7
The scuba diver was 38 feet below sea level. $\to$ -38
The basement is 8.3 feet below ground. $\to$ -8.3

Statements that represent positions above the sea level are illustrated using the positive sign, while positions below the sea level are represented using the negative sign.

The above highlights imply that the following statements would be represented with positive sign:

A building is 38 feet tall.
Erica jumped 2.7 feet above ground.

This is so, because height and positions above the ground are above the sea level

Also, the following statements would be represented with negative sign:

Oliver owes his sister $27. $\to$ -27
The scuba diver was 38 feet below sea level. $\to$ -38
The basement is 8.3 feet below ground. $\to$ -8.3

This is so, because debt and positions below the ground are below the sea level
