The figure seems like its a parallelogram.

In a parallelogram :
Opposite sides are equal and
Opposite angles are equal
Hence, The side opposite to 9in. is equal to 9in. and the side opposite to 10in. is equal to 10in.

Area of the figure =b×h
= 8×10
=80in.sq.

Area = b x h = 8 in. x 10 in. = 80 in.

Perimeter = 2 x l + 2 x w = 2 x 9 + 2 x 10 = 38 in.

A circular plot with a 160 foot diameter is watered by a spray irrigation system. To the nearest square foot, what is the area t

Anuta_ua [19.1K]

A circular plot is watered by a sprinkler that rotates through it. The sprinkler only rotates through a semi-circle, or half of the whole circle.

Area of a circle: A = pi x r^2

r = 160 / 2 = 80

A = pi x 80^2

A = 6400pi / 2 = 3200pi

3200pi = 10053.0965

The area water is approximately 10,053 ft^2.

Hope this helps!! :)

Amy drops a ball from an initial height of 30 feet above the ground. After how many seconds with a ball reach the ground? Roger

Vitek1552 [10]

Answer:

Option 2. 1.4 seconds

Step-by-step explanation:

As we know when a ball is dropped from a height then we apply the formula

$h=ut+\frac{1}{2}gt^{2}$

Here h = height from the ground

u = initial speed of the ball

t = time taken to reach the ground

g = acceleration due to gravity

Now we put the values of these parameters

h = 30 feet ≅ 9.144 met.

u = 0

g = 9.8 met/sec²

9.144 = 0 + 1/2×9.8×t²

9.144 = 4.9×t²

t² = 9.144÷4.9

t² = 1.87

t = 1.37 ≅ 1.4 seconds

Therefore option 2 is the answer.

Max and Tyler collected 174 plastic bottles from the playground. Tyler collected twice as

drek231 [11]

The answer is 116.
You would do 174 / 3 since Tyler collect twice as many as max did, to get how much max has, and doubled it by doing 58 x 2
