Nataliya [291]

Answer:

2.5 inches

Step-by-step explanation:

1 feet = 12 inches

The length is 16 ft x 12 = 192 inches

The length was scales by an unknown measure which i would represent with x . The equation is as follows

192 inches x a = 4 feet

a = 48

The kitchen was scaled by 48

10 x 12 = 120 inches

120/48 = 2.5 inches

A window in Michael's room is the shape of a trapezoid. The bases are 30 inches and 40 inches. The height of the window is 24 in

lana [24]

Answer:

The area of the window is of 840 square inches.

Step-by-step explanation:

To find the area of an trapezoid, we need to add the sum of the bases, multiply by the height, and then divide by 2.

Matematically:

$A = \frac{(b_{1} + b_{2})*h}{2}$

In which $b_{1}$ and $b_{2}$ are the bases and h is the height.

In this question:

$b_{1} = 30, b_{2} = 40, h = 24$

All the measures in inches, so the area is in square inches.

$A = \frac{(30 + 40)*24}{2} = 840$

The area of the window is of 840 square inches.

In a trolley ride around an amusement park, a child traveled from one signpost to a second signpost at a constant speed of 125 m

Inessa05 [86]

Answer:

Given speed of trolley = 125 meters per minute

$Speed= 125 meters/minute\\\\Speed =\frac{125}{60}meters/second\\\\Speed=2.083m/s$

Now we know that

Distance= Speed x time

Thus for the first case since the time of travel is less than 450 seconds thus the distance traveled is less than

Distance < 2.083 x 450 =937.5 meters

hence depending on the given information we cannot come to any conclusion weather the distance travelled is less than 800 m or greater than 800 m.

For the second case

since the time of travel is greater than 400 seconds

Thus the distance traveled is

$Distance>2.083\times 400=833.2meters$

which is greater than 800 meters.
