Answer:

b=8

Step-by-step explanation:

1.1     Pull out like factors :

-8 - b  =   -1 • (b + 8)  

Solving a Single Variable Equation

2.1      Solve  :    -b-8 = 0  

Add  8  to both sides of the equation :  

                     -b = 8

Multiply both sides of the equation by (-1) :  b = -8

Calculate the perimeter of a square whose diagonal measures 29 dm.
mojhsa [17]

Answer:

4\sqrt{420.5} dm

Step-by-step explanation:

A square's diagonal cuts across the square, making two right triangles where the diagonal is the hypotenuse.

We have a right triangle with a hypotenuse of 29, and two legs that are the same length (because they are sides of a square)

So, we can use pythagoreans theorem to find the lengths of the legs, or sides of the square.

a^2 + a^2 = 29^2

2a^2 = 841

a^2 = 420.5\\

a = \sqrt{420.5}

Now that we have a side length of \sqrt{420.5}, we just have to multiply that by 4, since a square has 4 sides. This leaves us with a final perimeter of:

4\sqrt{420.5}

Brandon is paid 150% of his regular hourly rate for overtime hours. He is paid \$45.00 an hour for overtime hoursWhat is his reg
Ne4ueva [31]

Answer:

Regular hourly rate for Brandon is $30

Step-by-step explanation:

Let the payment for regular hours be $x

given that

Brandon is paid 150% of his regular hourly rate for overtime hours

payment for overtime hours = 150% of payment for regular hours

payment for overtime hours = 150/100 * x = 3x/2

Given that He is paid \$45.00 an hour for overtime hours

thus,

3x/2 = 45

=> x = 45*2/3 = 30

Thus,  regular hourly rate for Brandon is $30
