Nathena needs to buy a fence to put around her rectangular yard for her dog. Nathena forgot the width of his yard, but knows the

BabaBlast [244]

Answer:

The real answer is 6

Step-by-step explanation:

Fairly simple. You know the length and the area, but you don't know the width. So your equation looks like this: 30 x ? = 180. But to figure out the width, you change the position of the numbers in the equation like this:

180 ÷ 30 = ?. Then you solve. 180 ÷ 30 = 6. If you want to double check your answer, you can plug in your answer to your original equation, 30 x 6 = 180.

Hope this helps!

A biologist wants to know the width w of a river in order to properly set instruments for studying the pollutants in the water.

belka [17]

Answer: The river is 148.3 feet wide.

Step-by-step explanation:

Alright, lets get started.

Please refer the diagram I have attached.

The triangle formed is a right triangle.

Using SOH CAH TOA

$tan 56 = \frac{x}{100}$

Multiplying 100 in both sides

$x = 100 \times tan56$

$x = 100 \times 1.4826$

$x = 148.26$

Rounding to the one decimal place

$x = 148.3$

Hence river is 148.3 feet wide. .............. Answer

Hope it will help :)
