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.

If a car travels 120 miles in 2 hours, what is its rate of speed expressed as a unit rate?​
erastovalidia [21]

The speed is 60 miles per hour

Step-by-step explanation:

Speed is the distance covered per unit time.

The formula for speed is:

Speed = \frac{distance}{time}\\

Given

Distance = d = 120 miles

Time = t = 2 hours

Putting the values in the formula

s = \frac{d}{t}\\=\frac{120}{2}\\= 60

The speed is 60 miles per hour

Keywords: Speed, distance

You are standing 25 feet from the base of a flagpole.The angle of elevation to the top of the flagpole is 40°.What is the height
liraira [26]

Answer: the height of the flagpole is 21 ft

Step-by-step explanation:

Since the angle of elevation to the top of the flagpole is 40°, a right angle triangle is formed. The height of the flagpole represents the opposite side of the right angle triangle. Your distance from the base of the flagpole represents the adjacent side of the right angle triangle. Therefore, to determine the height of the flagpole, x ,we would apply the tangent trigonometric ratio which is expressed as

Tan θ = opposite side/adjacent side

Tan 40 = x/25

x = 25tan40 = 25 × 0.8391

x = 20.98

x = 21.0 ft to the nearest tenth.
