$10,800

B)

$16,200

Eliminate

C)

$21,600

D)

$29,700

Answer:

Answer:

C

Step-by-step explanation:

yearly depreciation

32,400÷12

=2,700

Accumulated depreciation for 4 years

2,700×4

=10,800

Book value at year 4

32,400−10,800

=21,600

Answer:

Answer:

C) $21,600correct answer

COLLEGE

in the morning there were s students in the library in the afternoon there were 4 fewer students in the library than in the morning write an expression for the number of students in the afternoon.

Hello there!

In the morning there were s students in the library. In the afternoon, there were 4 fewer students in the library than there were in the morning. Write an expression for the number of students in the afternoon.

4 fewer means -4.

S - 4 is the expression that is equivalent to the amount of students who were in the library in the afternoon.

I hope this helps!

A horse ran 800 meters in 40 seconds, 1,200 meters in 60 seconds,and 480 meters in 24 seconds. Is this a proportional relationship? If so, what is the constant of proportionality? What does it represent. Write an equation to represent the distance d , in meters, that the horse runs in t seconds

The given data is in proportion. Therefore, an equation to represent the distance d ,in meters, that the horse runs in t seconds is d=20t.

What is a proportional relationship?Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".

Given that, a horse ran 800 meters in 40 seconds, 1,200 meters in 60 seconds and 480 meters in 24 seconds.

Here,

800/40 =20, 1200/60 =20 and 480/24=20

Now, in proportional relationship d∝t

d=kt

800=k×40

k=20

d=20t

The given data is in proportion. Therefore, an equation to represent the distance d ,in meters, that the horse runs in t seconds is d=20t.

Yes, there is a proportional relationship in this data, it’s is 20 meters per second. It represents the horse running at 20 meters per second. The constant of proportionality is 20/1 The equation would be 20t=d
