The Cosmic Pool company is building a pool in Mary’s back yard. The pool is to be 8ft longer than it is wide and cover 240 squar

Aneli [31]

Answer:

The correct answer is C.

Step-by-step explanation:

Since the Cosmic Pool company's pool's length is 8ft longer than the width, you can immediately rule out choices A and B, since their <em>widths</em> are greater than their <em>lengths</em> by 8, and not vice versa. This leaves choices C and D. The perimeter of a quadrilateral's formula is $2(l+w)$ , which means the length plus the width and multiplied by 2. Using this formula, you can infer that the perimeter is $2(20+12)$ = $2*32$ = 64ft, so choice C is the correct answer.

What is the best estimate for this sum?

Pavlova-9 [17]

Answer:

The sum is close to 1/2

Step-by-step explanation:

1/4 = 7/28
2/7 = 8/28
7/28 + 8/28 = 15/28

14/28 = 1/2 and 15/28 is close to 14/28

9 m<br> 3 m<br> 3 m<br> What is the area, in square meters, of the shaded region in the diagram?

NeTakaya

Answer:

Notice that the side length of the square is 38 m.

area of square = (side length)2 = (38 m)2 = 1444 m2

Notice that the diameter of the circle is 38 m .

And its radius = diameter / 2 = 38m / 2 = 19 m

area of circle = pi * radius2 = pi * (19m)2 = pi * 361 m2 ≈ 1133.54 m2

So......

area of shaded region = area of square - area of circle

area of shaded region ≈ 1444 m2 - 1133.54 m2

area of shaded region ≈ 310.46 m2

Step-by-step explanation:

Notice that the side length of the square is 38 m.

area of square = (side length)2 = (38 m)2 = 1444 m2

Notice that the diameter of the circle is 38 m .

And its radius = diameter / 2 = 38m / 2 = 19 m

area of circle = pi * radius2 = pi * (19m)2 = pi * 361 m2 ≈ 1133.54 m2

So......

area of shaded region = area of square - area of circle

area of shaded region ≈ 1444 m2 - 1133.54 m2

area of shaded region ≈ 310.46 m2
