Answer:

An employee would have to work 20 years in order to receive an annual pay of $45,000

Answer:

20 units

Step-by-step explanation:

The Pythagorean Theorem states that:

                                [tex]a^{2} + b^{2} = c^{2} \\[/tex]

Now we can insert values into the equation.

                                      [tex]a = 15\\b = b\\c = 25\\[/tex]

Now we can plug these ☝ values into the Pythagorean Theorem:

                                  [tex]15^{2} + b^{2} = 25^{2}\\[/tex]

After we solve for [tex]b[/tex] we get:

[tex]b^{2} = 400\\b = 20[/tex]

Answer:

b = 20

Step-by-step explanation:

15 + b = 25

(you have to square each one)

15 x 15 = 225

b x b = b

25 x 25 = 625

625 - 225 = 400

[tex]\sqrt{400}[/tex] = 20

Answer:

r= -189

Step-by-step explanation:

Answer:

r= -189

Step-by-step explanation:

You subract the 8 both sides:   -13= r/9+8

Which equals to: -21= r/9

In order to get the 9 off, you have to cancel it by multiplying ( opposite of   is multiplying) both sides:

9(-21)= r

And the final answer is:  r= -189

You can check it by plugging in -189 to r and it works:)

Answer:

1005 ft squared (B)

Step-by-step explanation:

The far left area:

30*15=450

The middle area:

-Since there is an eight feet being subtracted it is:

22*15=330

The last side:

-Since there is two 15's at the bottom we must subtract 30 from 45:

15*30*1/2=225

Add the area together:

450+330+225=1005

1005 ft squared

Answer:

A

Step-by-step explanation:

Answer:

b

Step-by-step explanation:

convert 2 1/2 hours into minutes to be easier to work with

15 / 150 = 10 minutes

every 10 minutes he pots a plan.

there are 210 minutes in 3 1/2 hours

210 / 10 = 21  

Answer:

2^-2

Step-by-step explanation:

According to the properties of integer exponents, 1/a^n = a^-n.

So 1/2 x 1/2 = 1/2^2 = 2^-2.

1/2 x 1/2 can be rewritten as the exponential expression 2^-2.

Edmentum answer

The expression 1/2 × 1/2 can be written as 2⁻² in the exponential form with the base 2.

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

Given expression is 1/2 × 1/2.

We have to write the expression in an exponential form with the base 2.

1/2 × 1/2 = (1/2)²

             = 1 / 2²

We have the rule for exponentiation 1 / aᵇ = a⁻ᵇ

1/2 × 1/2 = 2⁻²

Hence the exponential form of the given expression with the base 2 is 2⁻².
