Answer:

18.1

Step-by-step explanation:

You can use the c = b/cos(a) which when subsituted gives u c= 16/cos(28) which when u solve gives u 18.12112

Mike discovered that the pool in his backyard is leaking slowly. The pool holds 13,257 gallons of water, and is leaking at a rat

andre [41]

12,165 gallons
After multiplying 14 and 78 which will equal all the gallons leaked
You will get
1,092
After that just subtract
13,257
With 1,092
Which equals 12,165

Solve this fraction based question for 20 points.

MrRa [10]

The simplified form of the expression is -11/9

<h3>Rational expressions</h3>

These are expressions written as fractions. Given the following fraction

$\dfrac{\frac{5}{8} +\frac{3}{4} }{\frac{-2}{3}-\frac{5}{6} }$

Find the LCM of the numerator and denominator

$\dfrac{\frac{5}{8} +\frac{3}{4} }{\frac{-2}{3}-\frac{5}{6} }\\\dfrac{\frac{5+6}{8} }{\frac{-4-5}{6} } \\\dfrac{\frac{11}{8} }{\frac{-9}{8} }$

Divide the result to have:

11/8÷-9/8

11/8 * 8/-9
-11/9

Hence the simplified form of the expression is -11/9

All you have to do in order to solve for the length of the square, simply take the expression and divide each term in the equation by 4, since the perimeter equation is the result of the length of the side equation multiplied by 4.

The final solution would be C.

A rectangle that is 6 feet by 9 feet has been scaled by a factor of 1/3.

OleMash [197]

The side lengths of the scaled copy are 2 feet by 3 feet and to scale the copy back to its original size, the scale factor to use is 3

<h3>1. What are the side lengths of the scaled copy? feet by feet</h3>

The given parameters are:

Length = 6 feet

Width = 9 feet

The scale factor is given as:

k = 1/3

So, the side lengths of the scaled copy are

Length = 1/3 * 6 feet = 2 feet

Width = 1/3 * 9 feet = 3 feet

Hence, the side lengths of the scaled copy are 2 feet by 3 feet

<h3>2. Suppose you want to scale the copy back to its original size. What scale factor should you use?</h3>

In (1), we have:

The scale factor is given as:

k = 1/3

To scale the copy back to its original size, the scale factor to use is:

Scale = 1/(1/3)

Evaluate

Scale = 3

Hence, to scale the copy back to its original size, the scale factor to use is 3
