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 :)

Answer:

9 white ribbons were awarded

Step-by-step explanation:

make white x

make blue b and make red r

b=x-1

r=x+3

w=x

add them up

x-1+x+3+x=29

x-1 +x+3 is 2x+2

2x+2+x=29

3x+2=29

subtract 2 on both sides

3x=27

divide by 2

x=9

14. Twelve more than seven times a number equals the number less six
kotegsom [21]

Answer:

The number is -3.

Step-by-step explanation:

Set up an equation:

Variable n = number

12 + 7n = n - 6

Assuming the question is solve for n, isolate the variable:

Subtract n from both sides:

12 + 6n = -6

Subtract 12 from both sides:

6n = -18

Divide by 6 on both sides:

n = -3

Check your work:

12 + 7(-3) = -3 - 6

12 - 21 = -3 - 6

-9 = -9

Correct
