Answers

Answer:

Profit = $6

Step-by-step explanation:

The box of apple that the man bought contained 100 apples.

To know if he made profit or loss.

Sales price - cost price

$50 - $44

= $6

This man made profit of $6 from the sales of the apples from the calculation above.

Kevin went to a store that offers a 20% discount. He bought a jacket and saved $11.20 after using the coupon. What is the original price of the jacket?

Answers

Answer: $56

Step-by-step explanation:

Let the original price of the jacket be x.

Since Kevin went to a store that offers a 20% discount and bought a jacket and saved $11.20 after using the coupon.

The original price of the jacket goes thus:

20% × x = $11.20

0.2 × x = 11.20

0.2x = 11.20

x = 11.20 / 0.2

x = 56

The original price of the jacket will then be $56

Bruce's school is due west of his house and due south of his friend Avery's house. The
distance between the school and Avery's house is 6 miles and the straight-line distance
between Bruce's house and Avery's house is 7 miles. How far is Bruce's house from school? If
necessary, round to the nearest tenth.

Answers

Answer:

3.6 miles

Step-by-step explanation:

The three points form a right triangle. The hypotenuse is the distance from Bruce and Avery's house, and the first leg is the distance from Avery's house to the school. Using the Pythagorean Theorem's converse, sqrt(7^2-6^2), and rounding it to the nearest tenth, we get 3.6 miles.

A dragonfish is swimming at -900 m relative to sea level. It rises 250 m. What is the dragonfish´s new depth relative to sea level? Show your work.

Answers

Answer:

1150 m

Step-by-step explanation:

Given that,

A dragonfish is swimming at -900 m relative to sea level.

It rises 250 m.

We need to find the dragonfish´s new depth relative to sea level. Let the new position is x. So,

x = 250-(-900)

= 250+900

= 1150 m

Hence, the new position is 1150 m.

5000 containers are stacked 20 wide and 50 long on a ship. How many containers high are they? Pls answer and give explanation, thx

Answers

Answer:

5 containers high

Step-by-step explanation:

Given that :

Given :

Width = 20 containers

Length = 50 containers

Total containers = 5000

Hence,

Total containers = width * length * height

5000 = 20 * 50 * height

5000 = 1000 * height

Height = 5000 / 1000

Height = 5 containers

Marcy is trying to rise $425. She has raised 65% of her goal. How much more money does she have to raise?

Answers

So this is just gonna be a disorganized mess.

So first, we gonna find how much money she earned so far. So we convert the percentage to a decimal, which is 0.65. Now we multiply.

425x0.65=276.25

We now know how much she earned.

Next, we find how much left she has to earn. First, we have to find the percentage she has left to earn. So we subtract 100-65, which is 35. Now we multiply 425x0.35 to find that percentage.

425x0.35=148.75

To double check, we add 276.25 and 148.75 to see if they equal 425.

276.25+148.75=425.

So she needs to earn $148.75 to reach her goal
