Your car is worth $20,000 but it depreciates at a rate of
12% each year.
Write an equation showing how much your car is worth
each year.
A)f(x) = 20,000 - 12x
B)f(x) = 20,000 - 1.12*
C)f(x) = 20,000 -12%
D)f(x) = 20,000 - 0.88%

Answers

Answer 1

Answer:

D

Step-by-step explanation:

since the car value is decreasing by 12% each year, just take the original  amount and multiply by 88% to get the value of the car for the next year, so on and so forth

Answer:

b     3 was not multiplied by −4

Step-by-step explanation:

The correct way to apply the distributive property is to multiply 3 by p and multiply 3 by -4 as shown below.

3(p − 4) = 3p + 3 × (-4) = 3p - 12

His attempt is

3(p - 4) = 3p - 4

He did multiply 3 by p, but h did not multiply 3 by -4.

The jelly bean jar has a square

What would be a reasonable
upper limit for the number of
jelly beans in the jar?
A.1
B.10
C.100
D.10,000

Answers

Answer:

A.1

Step-by-step explanation:

those jelly beans are big.. its either 1 or 10 like 17cm is as long as your hand(just your hand and fingers not ur arm)

so A.

The reasonable upper limit of the bean jar is the same as the height of the jar so it will be 17cm so none of the given options will be correct.

What is volume?

Volume is the scalar quantity of any object that specified occupied space in 3D.

For example, the space in our room is referred to as volume.

The volume of cuboid = length × height × width.

The volume of the cube = side³.

Given a jar with a square base

Length = 12.5 cm

Width = 12.5cm

Height = 17 cm

The jelly beans will cover all heights of the jar so the maximum height of the jelly will be the same as the height of the jar.

Hence "The reasonable upper limit of the bean jar is the same as the height of the jar".

Type your answer

Answers

Hey there!

Let's make an equation

⇒y = (a)(x)(z)

y = 80x = 5z = 8

⇒ 80 = a(5)(8)

⇒ 80 = a(40)

⇒ 80 = 40a

Divide both sides by 40

⇒40a/40 = 80/40

⇒a = 80/40

Therefore, a = 2

Let's substitute into first equation

⇒y = (2)(16)(2)

y = 64

So, y = 64

Quadrilateral DEFG has side lengths of 16 m, 32 m, 28 m, and 12 m. Quadrilateral D'E'F'G' has side lengths of 44 m, 88 m, 77 m, and 33 m.

The figure D' E' F' G' (is/is not) a dilation of the figure D E F G. Thr ratios of the lengths of the corresponding sides (are not/are) equal.​

Answers

Answer:

  is a dilation

Step-by-step explanation:

One of the triangles will be a dilation of the other if corresponding sides have the same ratio. When given a series of side lengths, there are a couple of ways you can determine if the ratios are the same.

compute the ratio of the side of one figure to the corresponding side of the other figureput corresponding side lengths in order around the figure, and remove any common factor from their values.

Sometimes the latter approach is easier.

__

DEFG ratios are 16 : 32 : 28 : 12 = 4 : 8 : 7 : 3 . . . . . . remove a factor of 4

D'E'F'G' ratios are 44 : 88 : 77 : 33 = 4 : 8 : 7 : 3 . . . . remove a factor of 11

The figure D'E'F'G' is a dilation of the figure DEFG. The ratios of the lengths of the corresponding sides are equal.​

Austin is building a miniatuer replica of the empire state building.The actual empire state building is 1,423 feet tall and 6,000 feet wide .If astin's replica has a width of 60 centimeters, what is the height of his empire state building replica rounded to the nearest centimeter?

Answers

Answer: 14cm

Step-by-step explanation:

From the question, we are informed that Austin is building a miniatuer replica of the empire state building and that the actual empire state building is 1,423 feet tall and 6,000 feet wide

We are further told that Austin's replica has a width of 60 centimeters. This implies that the scale of 1:100 was used where 1cm represents 100 feet

= 60:6000

= 1:100

Therefore, the height of his empire state building replica rounded to the nearest centimeter will be:

= 1423/100

= 14.23cm

= 14cm approximately
