Answer 1

Answer:

7. 23

8. 18

9. 55

10. 17

Step-by-step explanation:

Answer 2
3+4 x 5^1
7 x 5^1
=35

26-4^2 / 5^1
22^2 / 5^1
484 / 5
= 96.8

(3^3 - 2^4) x 5
(37 - 16) x 5
21 x 5
= 105

20 - (5 - 2)^2 + 2 x 3
20 - (3)^2 + 2 x 3
20 - 9 + 2 x 3
20 - 9 + 6
20 - 15
=5

The correct answer is

20n: $120

$120

The total made would be found by multiplying the amount me makes per game by the number of games he referees.

Total = 20n

To find the total for 6 games replace n with 6:

Total = 20(6)

Multiply:

Total = $120

3 algebra questions ill give brainliest!! no random answers or ill report.

Answers

Answer:

14)$9,320.00. 15)Chen has 8 nickels, 2 dimes, and 6 quarters.     16)10%

Step-by-step explanation:

14)A = $9,320.00

I = A - P = $1,320.00

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 5.5%/100 = 0.055 per year.

Solving our equation:

A = 8000(1 + (0.055 × 3)) = 9320

A = $9,320.00

The total amount accrued, principal plus interest, from simple interest on a principal of $8,000.00 at a rate of 5.5% per year for 3 years is $9,320.00.

16)R = 1011.1111%/year

Equation:

r = (1/t)(A/P - 1)

Calculation:

Solving our equation:

r = (1/1)((1250/112.5) - 1) = 10.11111111

r = 10.11111111

Converting r decimal to R a percentage

R = 10.11111111 * 100 = 1011.1111%/year

The interest rate required to get a total amount, principal plus interest, of $1,250.00 from simple interest on a principal of $112.50 over 1 years is 1011.1111% per year.

Answer:

about 3.1%

Step-by-step explanation:

I hope that helped you

Answer:

Hello!

The formula for percentage increase is:

Percent Increase = {( New Value - Old Value) / Old Value × 100}

Substitute = {( 566.60 - 550) / 550 × 100]

Solve:

566.60 - 550 = 16.6

16.6 / 550 = 0.0301818182

0.0301818182 × 100 = 3.0181818182

You may round that to 3.1%

So, Mr. Dawkins' salary increased by about 3.1%

HELP MEH Please write the coordinates of the x-intercept: y = 500

Answers

Well, there needs to be an equation.

Answer:

See explanation

Step-by-step explanation:

The x- intercept is where the line crosses the x- axis. Let y = 0 in the equation and solve for x

5(0) = 2x - 1, that is

0 = 2x - 1 ( add 1 to both sides )

1 = 2x ( divide both sides by 2 )

The x- intercept is ( , 0 )

The y- intercept is where the line crosses the y- axis. Let x = 0 in the equation and solve for y

5y = 2(0) - 1

5y = - 1 ( divide both sides by 5 )

y = -

The y- intercept is (0, -  )
