A local school needs to paint the floor of its theater room, where the length of the floor, x, is at least 12 feet. The width of the floor is 4 feet less than the length. It will have a stage and a closet, and the remaining area of the floor will be painted. The dimensions are shown in the diagram:

rectangle with length of x ft and width of x minus 4 ft, right triangle inside labeled stage with height of x minus 4 ft and base of 6 ft, rectangle inside labeled closet with length of 7 ft and width of 2 ft, the rest of the rectangle is labeled floor

Let A represent the painted area, in square feet, of the floor. Choose the correct equation to solve for area (A).

A = x(x − 4) + 0.5(6)(x − 4) + 2(7)
A = x(x − 4) − 0.5(6)(x − 4) − 2(7)
A = x(x − 4) − (6)(x − 4) − 2(7)
A = x(x − 4) + (6)(x − 4) + 2(7)

Answers

Answer 1

Answer: A=x(x-4)-0.5(6)(x-4)-2(7)

Step-by-step explanation:

A=x(x-4)-(0.5(6)(x-4) + 2(7))

A=x(x-4)-0.5(6)(x-4)-2(7)

Answer 2

Answer:

A = x(x − 4) − 0.5(6)(x − 4) − 2(7)

For question number 3 you would add 24+13+38. And that would give you 75. Making the fraction 75/100, in simplest form it would be 3/4. So the answer for number 3 is 3/4

For number 4: you add 0.5 and 3/10 together, but you can’t add a decimal and a fraction so we will convert the decimal to a fraction, 0.5 is equivalent to 1/2 so we will do 1/2 + 3/10. To add you have to find the most common multiple which would be 10. So now the equation is 5/10 + 3/10. Now all you have to do is add the numerators so 5/10+3/10=8/10. 8/10 in its simplest form is 4/5. Your final answer should be 4/5.

what is the value of x?

Answers

Answer:

x=4

Step-by-step explanation:

8×4=12°

20×4=80°

17×4=64

12+80+64=180

8x+20x+17x=180

add all together,

20+8=28+17=45

180/45=4

your answer is 4

to check sub x for 4

8x4=32

20x4=80

17x4=68

68+32=100

100+80=180

Referring to the figure, find the surface area
of the pyramid shown. Round to the nearest whole number.

Answers

Answer:

297 is the surface area

Step-by-step explanation:

Ok this problem is very simple.

First lets define some equations.

Area of a triangle: A = 1/2BH

A = Area   B = Base   H = Height

This equation works for right triangles only.

(because 2 right triangles make a square which is why it's multiplied by 1/2 because it's half a square).

Area of a square: A = BH

Surface area equals all the areas of each side added together.

First lets find the area of one of the triangles.

We know 11 is the base and 8 is the height but the triangle isn't a right triangle.

To make it a right triangle divide the base by 2 so 11/2.

You will get 5.5.

Now find the area!

A = 1/2BH

A = 1/2(5.5)(8)

A = 1/2(44)

A = 22

So now we found the area of the right side as a right triangle but you must multiply it by 2 to get the entire side (because we divided the base by 2).

22(2)=A

44=A

44 is the area of one side of the pyramid but there are 3 other sides (not including the base).

So just do:

44+44+44+44 = A

176 = A

Surface area for the triangles is 176!

Now we must find the area of the square.

A = BH

A = 11(11)

A = 121

Total surface area is all the areas added together so it's:

121+176=A

Julie ran 4 miles in 22 minutes. What is the unit rate in terms of minutes per 1 mile?

Answers

Julie runs 0.18 miles in one minute because 4 divided by 22 and you will get 0.18

Answer:

5.5 minutes

Step-by-step explanation:

4 miles = 22 minutes

1 miles = x minutes

22/4=5.5

1 mile = 5.5 minutes

Your beginning balance on your lunch account is $42. You buy lunch for $1.80 every day and sometimes buy a snack for $0.85. After 20 days, you have a balance of $0.05. How many snacks did you buy?

HELP

Answers

Explaination:

First your going to want to multiply the amount of days by how much money a school lunch costs:

1.80 x 20 = $36

The next step you will minus the amount spent by the beginning balance on your lunch account:

42 - 32 = $6

Then you will want to add the amount of money it costs for a snack untill it adds up high enough where it is close to the amount of money left (or you cant add any more):

0.85 + 0.85 + 0.85 + 0.85 + 0.85 + 0.85 + 0.85 = $5.95

You then count the times you added 0.85 which would be 7 times.

You can also multiply 0.85 by 7 to shorten it up:

0.85 x 7 = $5.95

This would leave $0.05 left.
______________________
Final answer:

After 20 days you would have 7 snacks total.

Step-by-step explanation:

The sum of two interior angles other than the adjacent angle of extended length will be equal to the external angle of extended length thus m∠PQR will be 18°.

What is an angle?

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

In any triangle,The sum of two interior angles other than the adjacent angle of extended length will be equal to the external angle of extended length.

In the given triangle below image,

m∠PQR = m∠OPQ + m∠POQ

4x - 10 = x + 9 + x - 5

4x - 10 = 2x + 4

2x = 14

x = 7

So,

m∠PQR = 4(7) - 10 = 18°

Hence "The measure of m∠PQR will be 18° for the given triangle".

3 liters of water are shared equally by 5 people how much water does each person get? division equation to represent the situation

Answers

600 mililiters each

Step-by-step explanation:

1 liter is equal to 1000 mililiter and is multiplied by 3 and the answer is devided into 5.

The division equation that represent the situation is 3/5 and each person will get 0.6 liters of water.

What is division?

The division is one of the four basic mathematical operations, the other three being addition, subtraction, and multiplication.

Now it is given that,

Number of People = 5

Liters of water = 3

So, Water shared by each person = Liters of water / Number of People

⇒ Water shared by each person = 3/5

This is the division equation to represent the situation.

⇒ Water shared by each person = 0.6

Thus, the division equation that represent the situation is 3/5 and each person will get 0.6 liters of water.
