Answer:

Volume of prism = 4000 cm cubed

Step-by-step explanation:

Given that:

Height of rectangular prism = 5 meters

Converting into centimeters as the area of base is in centimeters.

1 meter = 100 centimeter

5 meters = 500 cm

Area of the base = 8 cm squared

Volume of prism = Area of base * Height

Volume of prism = 8 * 500

Volume of prism = 4000 cm cubed

Hence,

Volume of prism = 4000 cm cubed

Answer:

No it doesn't

Step-by-step explanation:

The equation we have is

Y = 150x

We have x = 4 hours

This is a simple question. We have to plug in the x = 4 in the equation to find out if we would have 640 brushes. If y = 640, then it models it. But if y is not equal to 640, it doesn't.

So let's solve this to see for ourselves.

Y = 150(x)

We put the value of x

Y = 150(4)

Y = 600

So we can see that the equation does not model the number of brushes made each hour. This equation models 600 brushes and not 640.

Answer:

$405.60

Step-by-step explanation:

520x.22= 114.4

520-114.4=405.60

Answer:

c = 3.45 * p

Step-by-step explanation:

Since the total cost of Cheddar Cheese is dependant on the number of pounds that are being purchased then to calculate the total cost we would need to multiply the price per pound by the number of pounds being purchased. Therefore, the following equation would best represent the total cost of the cheddar cheese...

c = 3.45 * p

Answer:

3 inches

Step-by-step explanation:

If we're gonna have some sort of increase each year, it's gonna pop up in our model attached to a variable, because it represents some kind of change, and variables can change. Looking at our equation, the 28.6 represents our starting point: the boy is 28.6 inches tall when he's 2 years old. The 3a term, then, represents the boy's increasing height each year. When he's 3 years old, a = 1, and so h = 3 + 28.6 = 31.6 inches. When he's 4, a = 2, and h = 3 + 31.6 = 34.6. The increase is always 3 inches.

I think it might be 1.25

Step-by-step explanation:

Problem 1

This answer will vary from person to person. And as your teacher says, you can also randomly pick a value if you aren't sure.

Let's say you spend an hour each day talking on your phone. This means voice calls and not texting. Video calling could also be part of voice calling, though it will depend on how your cell phone company structures the cell phone plan.

Anyways, let's go with 1 hour. This converts to 60 minutes.

If you talk for 60 minutes per day, then you spend 60*30 = 1800 minutes per month talking on the phone. This is an average value. I'm using 30 days per month.

Answer: 1800 minutes

=====================================================

Problem 2

For each of the 6 companies, form their respective equations

x = number of minutes

y = total cost per month

We get the following equations for each company:

With those 6 plans in mind, we will plug x = 1800 into each equation

Doing so leads to...

So we can see that clearly Public Mobile has the lowest cost per month at $24 a month. The cost per minute of $0 means that we have unlimited minutes here. The other costs are really high and far from $24. The next smallest value is $190, which is far from $24.

Is Public Mobile always the best choice? It depends. Refer to the chart below (attached image) and you'll see that the yellow cells are instances when Public Mobile isn't the cheapest option. However, note how small x has to be for this to occur and note how the yellow cells don't show up very often. Sure we could make more yellow cells pop up if we used even smaller x values, but at a certain point, it's likely not to be realistic. Why have a cell phone plan if you don't use the minutes to talk on it? Of course, everyone is different.

Anyway, for the x value chosen in problem 1, the Public Mobile plan is the cheapest option at $24 per month.

Answer: Public Mobile

Answer:

The circumference of the circle is approximately 92 mm

Step-by-step explanation:

For us to be given the radius of the tokens it is safe for us to make the assumption that the token is circular in shape. Thus, we can solve the problem using various theories in circle geometry.

We will use the circumference equation to estimate the circumference of the circle, assuming the value of π is = 3.14

The circumference of a circle can be given as 2 X π X radius

This will be 2 X 3.142 X 15 = 94.247 ≈92mm

Therefore, the circumference of the circle is approximately 92 mm

Step-by-step explanation:

25 divided by 5 = 5

45 divided by 5= 9

so 25/45 = 5/9

5x3=15

9x3=27

so 5/9=15/27

Answer:

540 degrees if that's what your looking for.

Step-by-step explanation:

A square always equals 360 degrees while a circle is the same thing. take the half of the circle to get 180 then add them together to get 540

Answer:

C. He would solve 32 math problems if he played video games for 8 hours.

Step-by-step explanation:

Create the following proportion to find the number of math problems for 8 hours:

4/16 = 8/x

Cross multiply.

4 x x = 4x

16 x 8 = 128

4x = 128

x = 32

If Tom plays video games for 8 hours, he'll solve 32 math problems.

Create the following proportion to find the number of math problems in 9 hours:

4/16 = 9/x

Cross multiply.

4 x x = 4x

16 x 9 = 144

4x = 144

x = 36

If Tom plays video games for 9 hours, he'll solve 36 math problems.

Answer:

13.1 miles

Step-by-step explanation:

she needs 16 miles total

she has driven 2.9

so

16 - 2.9 = 13.1

Step-by-step explanation:

You would need to subtract 2.9 from 16 to get 13.1

Answer:

4.75x=54+2.5x    x=24

Step-by-step explanation:

x=Number of games

4.75x=54+2.5x

Subtract 2.5x from both sides:

2.25x=54

Divide both sides by 2.25:

x=24

WHAT ANSWER WHERE IS IT

Step-by-step explanation:

Answer:

8 people got gumballs out of the machine.

Step-by-step explanation:

Given that:

Number of gumballs in machine = 78

Number of gumballs on each coin = 3

Number of gumballs left = 54

Let,

x be the number of people who put coin

Gumballs left = Total gumballs - 3*Number of people

54 = 78 - 3x

3x = 78 - 54

3x = 24

Dividing both sides by 3

[tex]\frac{3x}{3}=\frac{24}{3}\\x=8[/tex]

Hence,

8 people got gumballs out of the machine.
