Answer:

1. 14 ft

2. 72 in

3. 11 ft, 28 ft

4. 8 in, 96 in

Step-by-step explanation:

1. The area of a rectangle = length x width. The area is 28 sq ft and the width is 2ft, therefore:

28 = length x 2

length = 28/2 = 14 ft.

2. The perimeter is (length x 2)+(width x 2). The perimeter is 86 in and the length is 25 in, therefore:

86 = (25 x 2) + (width x 2) = 50 + (width x 2)

36 = width x 2

36/2 = width = 72 in.

3. The area is 33 sq ft and the width is 3 ft, therefore:

33 = length x 3

33/3 = length

length = 11 ft

The perimeter is (length x 2)+(width x 2), therefore:

p = (11 x 2) + (3 x 2) = 22 + 6 = 28 ft.

4. The perimeter is 40 in and the length is 12 in, therefore:

40 = (12 x 2) + (width x 2) = 24 + (width x 2)

40 - 24 = width x 2 = 16

width = 16/2 = 8 in.

The area is length x width, therefore:

Area = 12 x 8 = 96 in.

In one grade of 150 students, the ratio of boys to girls is 2:3. How many boys are in that grade?

trapecia [35]

Answer:

The numbers of boys in one grade are 60 .

Step-by-step explanation:

As given

In one grade of 150 students .

The ratio of boys to girls is 2:3.

Let us assume that the scalar multiple of boys and girls be x.

Thus number of boys = 2x

Number of girls = 3x

Than the equations becomes

2x + 3x = 150

5x = 150

$x = \frac{150}{5}$

x = 30

Thus number of boys = 2 × 30

= 60

Therefore the numbers of boys in one grade are 60 .

A ball is thrown downward from the top of a 240-foot building with an initial velocity of 20 feet per second. The height of the

telo118 [61]

Answer:

3.29 s

Step-by-step explanation:

We are given that

Height of building=240

Initial velocity=20ft/s

The height of the ball after t seconds is given by

$h(t)=-16t^2-20t+240$

When the ball strike the ground then

h(t)=0

$-16t^2-20t+240=0$

$4t^2+5t-60=0$

Quadratic formula:

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

Using the quadratic formula

$t=\frac{-5\pm\sqrt{25+960}}{8}$

$t=\frac{-5\pm\sqrt{985}}{8}$

$t=\frac{-5+31.28}{8}=3.29 s$

$t=\frac{-5-31.38}{8}=-4.5$

Time cannot be negative .Therefore,

t=3.29 s
