Answers

Answer:

Part A) 700 Snack Bags

Part B) [$]1225.00

Step-by-step explanation:

Pretzels and cheese puffs make up 30% (0.30) of the sales which means 210 is 30% of the total bags they sold. You could set up a ratio like this where 1 represents 100%:

210/.30 = x/1

If solved out, you find there are 700 bags total and you can check it by finding that 210 is 30% of 700.

Part a)700
Part b)1225$

She got 3 extra credit questions correct and recived 5 points for each. What is the total number of points she gained or lost overall

Answers

If I’m right it’s 15 points she gained and 10 points she lost if you combine them it’s 25 points
50 - (5•2)+(5•3)=
50 - (10) + (15) =

Answers

Answer:

In

In to point R, \text{m}\angle PQR = (7x-19)^{\circ}m∠PQR=(7x−19) ∘ , \text{m}\a

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".

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

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.

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.

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.

Teams of people worked to take out the bolts and put in the rivets.MARVELS OF ENGINERINGIts hard to imagine two more different structures than the Eiffel Tower and Hoover Dam. For one thing, the Eiffel Tower is in Paris, France, and Hoover Dam is on the border between Nevada and Arizona. The Eiffel Tower is elegant and delicate looking, but Hoover Dam looks like a huge slab of concrete. The Eiffel Tower was made of many parts put together. But the concrete for Hoover Dam was poured at the site. The Eiffel Tower was built for a fair and was not intended to remain in place for long. Hoover Dam was built to allow water to be used in desert country and to create electricity. Everyone expected it to remain in place for many, many years.Even though these two structures are so different, there are similarities. Each required great effort to complete. Each also necessitated the involvement of many workers. The workers on each faced many challenges and difficulties, and each was built in a series of steps. Each is huge but was built quickly, considering the amount of labor involved.All of the Eiffel Towers parts were made in a factory near Paris. Each piece had to be the right size and shape. Smaller parts were put together and then joined to form a larger piece. These large pieces were put together at the site of the tower. Bolts held together the pieces made at the factory. At the tower, these bolts were pulled out and replaced with hot rivets. Teams of people worked to take out the bolts and put in the rivets.Hoover Dam was built to replace one that had been washed away, but it was built in a new place. Four tunnels were blasted through rock to cause the Colorado River to flow in new directions. Then the rivers canyon walls had to be cleared. From great heights, workers dangled from ropes. With only air below their feet, they prepared the area for great concrete walls. Far underneath them, the area for the foundation was cleared of mud and loose rock. When this was finished, tons of wet concrete were poured into a gigantic form. For thirty months, concrete was poured until the work was done. Across the Colorado River stood a dam 700 feet tall. When the water was allowed to rush through tunnels, it passed through giant rotary engines, and as their parts whirled, they created electricity.Making electricity and using water to irrigate dry land were both practical purposes for Hoover Dam. But the Eiffel Tower had no original purpose but to be beautiful. The man who designed it, Gustave Eiffel, looked for a practical use for it. The tower was more than a thousand feet tall, and it was a perfect place for a radio antenna. So, a radio station was built on the tower.Both the Eiffel Tower and Hoover Dam are popular tourist attractions. Each is considered a marvelous example of engineering skill.
