Latasha earned 18 points on her quiz. If 24 points is equivalent to a score of 100%, which of the following proportions could she use to calculate her percent score? Select two that apply.

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:

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.

Answer:

£1,001,258

Step-by-step explanation:

(75x4000)+(62x5350)+(49x7542)=£1,001,258

The total sales revenue of the tickets is required.

The total ticket sales revenue was [tex]\$1001258[/tex]

Number of $75 tickets sold = 4000

Number of $62 tickets sold = 5350

Number of $49 tickets sold = 7542

We multiply the number of tickets and the cost of tickets and add them.

[tex]4000\times 75+5350\times 62+7542\times49=\$1001258[/tex]

Step-by-step explanation:

1.77245385091 square

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
