Answer:

A ≈ 9.0 ft²

Step-by-step explanation:

70° = 7π/18 radians

Area of the arc section

A = ½(7π/18)8² = 12⁴/₉π ft² = 39.09537 ft²

As the triangle is isosceles, the other two angles are (180 - 70) / 2 = 55°

law of sines 8 / sin55 = L / sin 70  L = 9.17722

so the triangle height  = √(8² - (9.17722/2)²) = 6.55321

Area of triangle ½(6.55321)(9.17722) = 30.07016

Area = 39.09537 - 30.07016 = 9.025211 ≈ 9.0 ft²

Step-by-step explanation:

Given parameters:

Amount earned by Jessica per month = 800

Total savings target per year  = 2400

Unknown:

Percentage of savings = ?

Solution:

The total earning per year will be the amount earned per month multiplied by the total number months;

 Amount earned in a year = 12 x 800  = 9600

Let the percentage of savings per year  = y%

  Now;

              2400 = \frac{y}{100} x 9600

                  y = 25%

Need help quickly its hard
kaheart [24]

Answer:

1-3x+8y

Step-by-step explanation:

Multiply y and 2

Multiply y and 1

The y just gets copied along.

2*y evaluates to 2y

Multiply x and 4

Multiply x and 1

The x just gets copied along.

The answer is x

4*x evaluates to 4x

2*y-4*x evaluates to 2y-4x

The answer is 2y-4x+8

2*y-4*x+8 evaluates to 2y-4x+8

Multiply y and 6

Multiply y and 1

The y just gets copied along.

The answer is y

6*y evaluates to 6y

2y + 6y = 8y

The answer is 8y-4x+8

2*y-4*x+8+6*y evaluates to 8y-4x+8

-4x + x = -3x

The answer is -3x+8y+8

2*y-4*x+8+6*y+x evaluates to -3x+8y+8

8 - 7 = 1

The answer is 1-3x+8y

2*y-4*x+8+6*y+x-7 evaluates to 1-3x+8y
