A roller coaster has 4 cars, each with the same number of seats. There are 21 passengers seated in
the roller coaster, but 3 seats are empty. Write an equation that can be used to determine the
number of seats in each car.

Answers

Answer:

[tex]4n = 24[/tex]

Step-by-step explanation:

Given

[tex]Cars = 4[/tex]

[tex]Empty = 3[/tex]

[tex]Occupied = 21[/tex]

Required

Determine an equation to find number of seats

Let the number of seats in each car be represented by n;

If [tex]1\ car = n[/tex]

Then:

[tex]4\ cars = 4 * n[/tex]

[tex]4\ cars = 4 n[/tex]

This implies that there are 4n total seats

Solving further:

[tex]Occupied\ Seats + Empty\ Seats = Total[/tex]

Substitute values for the above parameters:

[tex]21 + 3 = 4n[/tex]

[tex]24 = 4n[/tex]

Reorder

[tex]4n = 24[/tex] ---- This equation can be used to solve for n

I'm fairly sure its 4.93 grams.

Step-by-step explanation:

you take the origional water of 45.1ml and the new 52.3ml, and find the difference, which in this case is 7.2ml.

the density formula is D=M/V

D= Density

M=Mass

V=Volume

so it would be

D= 35.49/7.2

which is 4.93.

again this is just from what I remember of science class.

Answer: 4.93g/cm^3

Step-by-step explanation:

Formula for Density: D = mass / volume

We know that the mass of the unknown object is 35.49g

Mass = 35.49g

To find the volume

Initial water level: 45.1 mL

Final water level: 52.3mL

52.3cm^3 - 45.1cm^3 = 7.2cm^3

Volume = 7.2cm^3

Density = 35.49g/7.2^3

[tex] \frac{2}{5} x + 15 = x - 6[/tex]
x = [?]​

Answers

X= 35 hope this helpsss

Answer:

x = 35

Step-by-step explanation:

[tex]\frac{2}{5} x + 15 = x - 6[/tex]

First multiply through by 5 to eliminate the fraction

That's

[tex]5 \times \frac{2}{5} x + 15(5) = 5x - 30 \\ 2x + 75 = 5x - 30[/tex]

Next using the subtraction property subtract 5x from both sides

That's

[tex]2x - 5x + 75 = 5x - 5x - 30 \\ - 3x + 75 = - 30[/tex]

Next subtract 75 from both sides

[tex] - 3x + 75 - 75 = - 30 - 75 \\ - 3x = - 105[/tex]

Divide both sides by - 3

[tex] \frac{ - 3x}{ - 3} = \frac{ - 105}{ - 3} [/tex]

We have the final answer as

x = 35

A community is planning to build a rectangular garden. The width of the garden is 17 /4 feet (ft), and the perimeter of the garden is 24.5 ft. The community planners want to spread mulch on the entire garden. How many square feet of mulch will be needed?

Answers

Answer:

34 square feet

Step-by-step explanation:

First, you need to find the other side of the garden in order to find the area a=l*w

The formula to find the length is, p-w*2=x x÷2=l

because, perimeter is l+l+w+w and area is just l*w

4.25*2=8.50

24.50-8.50=16

16÷2=8

l=8

So now we need to multiply the length and width to get the area.

8*4.25=34 sq. ft.

I hope that helps!

The town of hillside has an elevation of 50 feet above sea level. The town of Lakeside has an elevation of -35 feet. A bicyclist rides from Lakeside to Hillside,and wants to find his change in elevation. He finds the difference between his final elevation, 50 feet, and his starting elevation, -35 feet. What is the difference?

Answers

Answer:

The difference is 85 ft.

Step-by-step explanation:

Elevation 1: 50 ft

Elevation 2: -35 ft

Difference = Elevation 1 - Elevation 2

Difference = 50 - (-35)

I can simplify this expression, as subtracting a negative number is the same as adding a positive number:

Difference = 50 + 35

Difference = 85

Answer: The difference is 85 ft.
