Janitors at Strickland High School empty 25 trash cans each day. The design of

each trash can is shown below.

Height- 4.5 inches

Length- 3 inches

Width- 2 inches

What is the total volume of trash that the janitors empty each day?

Round to the nearest tenth and don't forget to include units. The tick mark

on the numbers represents inches.

Answers

Answer: 675 cubic inches of trash

Step-by-step explanation:

Hi, to answer this question, first, we have to calculate the volume of each trash can :

Volume of a rectangular prism: width x length x height

Replacing with the values given:

V = 2 x 3 x 4.5= 27 cubic inches

Since there are 25 trash cans every day, we have to multiply the volume of each one by 25.

27 x 25 =675 cubic inches of trash

From the diagram we know that the radius of the circle is 7 in.

The formula for the circumference is C = 2(pi)(r).

Substituting 3.14 for pi and 7 in. for r, we get the final result, the circumference:

C = 2(3.14)(7 in) = 43.96 in

a. 8:1
b. 4:1
c. 1:2
d. 2:1

Answers

Answer:

Answer a (8:1)

Step-by-step explanation:

Surface area or volume?

I will assume it's volume.

The volume formula is V = s^3, where s is the length of one side of the cube.  If we double s, we get V2 = (2s)^3, or 8s^3, which is 8 times greater than thevolume of the cube with side length s.

The ratio is then    8s^3/s^3 or 8/1 or 8:1.

Subtract 30 from each side

An observer (0) spots a plane flying at a 55° angle to his horizontal line of sight. If the plane is flying at an altitude of 21,000 ft., what is the distance (x)
from the plane (P) to the observer (O)? (4 points)
A)20,793 ft
B)28,793 ft
C)36,585 ft
D)25,636 ft

Answers

Answer:

Option D. 25636 ft

Step-by-step explanation:

From the given right triangle,

Observer is at the point O and he observes the plane flying at point P.

Angel of elevation of the plane is 55° and altitude of the plane was 21000 ft.

To get the distance OP we will apply Sine rule in the given right triangle,

Sin 55 = [tex]\frac{h}{x}[/tex]

Sin 55 = [tex]\frac{21000}{x}[/tex]

x = [tex]\frac{21000}{\text{sin}55}[/tex]

x = 25636.27

x ≈ 25636 ft

Therefore, distance between the plane and observer is 25636 ft.

Option D. is the answer

Answer:

Option D. 25636 ft
