Answer:

She used the incorrect area formula.

She converted the mixed number to an improper fraction incorrectly.

She multiplied incorrectly.

Step-by-step explanation:

The area of a parallelogram is

A = bh not A = 1/2 bh

She started with the wrong formula

A = 7 2/5 * 2

Change to an improper fraction  

The improper fraction is 37/5  not 35/5

A = 37/5 *2

She multiplied incorrectly

A = 74/5

Goshia [24]

Answer:

546 ft³

Step-by-step explanation:

In the figure attached, the top view of the pool is shown. It can be decomposed into a trapezoid which height is 12 ft and which bases are 9 ft and 11 ft; and a rectangle which height is 1.5 ft and and it base is 11 ft.

Area of the trapezoid: (9 + 11)/2 * 12 = 120 ft²

Area of the rectangle: 1.5*11 = 16.5 ft²

Total area: 120 + 16.5 = 136.5 ft²

Volume of the pool: Total area * deep = 136.5 * 4 = 546 ft³

Solve |2x – 3| = 11. Show each step of your work.
Klio2033 [76]

Answer:

x =7       or              x = -4

Step-by-step explanation:

|2x – 3| = 11

There are two solutions to an absolute value equation, one positive and one negative

2x-3 =11    or 2x-3 = -11

Add 3 to each side

2x-3+3 = 11 +3    2x-3+3 = -11+3

2x = 14                 2x = -8

Divide each side by 2

2x/2 =14/2           2x/2 = -8/2

x =7                     x = -4

Solve and graph each of the following inequalities for x.
Ulleksa [173]

2x + 4 > 8

Step 1: Subtract 4 from both sides.

2x + 4 − 4 > 8 − 4

2x > 4

Step 2: Divide both sides by 2.

2x/2  >  4/2

x > 2

2x − 3 < 5

Step 1: Add 3 to both sides.

2x − 3 + 3 < 5 + 3

2x < 8

Step 2: Divide both sides by 2.

2x/2  <  8/2

x < 4
