The formula for density is p=m/v, which is fancy for density=mass/volume. If we plug in our mass and volume then me get, density=2/1
We all know 2/1 is 2, so now we know the density is 2 grams per milliliter
Commonly written as 2g/mL
density is mass divided by volume!! 2/1=2 so the answer is 2g/mL

A regular-size box of dog treats measures 3 1/4 inches by 7 1/2 inches by 12 inches. The manufacturer also sells a small-size box that has a volume that is 3/10 of the volume of the regular-size box.


What is the volume of the small-size box of dog treats?


Enter your answer as a mixed number in simplest form by filling in the boxes.

Answers

Answer:

87 3/4

Step-by-step explanation:

If the manufacturer also sells a small-size box that has a volume that is 3/10 of the volume of the regular-size box, then the volume of the small-size box of dog treats would be 87 3/4.

How to determine the volume of the box

To determine the volume of the box, we would first convert the measurements of the regular-size boxes to a proper fraction. We could proceed as follows:

3 1/4 inches = 13/4

7 1/2 inches = 15/2

12 inches

Now we sum the volumes as follows: (13/4) * (15/2) * (12/1)

= 585/2 cubic inches

Now, we would find 3/10 of  585/2 cubic inches

= 87.75 inches or 87 3/4 cubic inches.

A storage box has a base area of 314.5 square inches and a height of 8.5 inches.

What is the volume of 5 of these boxes?

Enter your answer as a decimal in the box.

Answers

Volume is base x height, and since you have 5 boxes, it’s the volume of 1 box, times 5. The base area x the height is 2,673.25, and when you multiply this by 5, you get 13,366.35 cubic inches.

Answer:

13366.25in cubed

Step-by-step explanation:

To find the volume of a rectangular prism, you need the formula:

V = (L × H) × W

Luckily, L × H is the base of the shape. So we can change it into:

V = B × W

Step 1

Plug in the values! That’s what we do everytime!

V = 314.5 × 8.5

Step 2

Multiply 314.5 by 8.5.

V = 2673.25

BUT ITS NOT THE ANSWER YET!

Step 3

Because you need  to find the volume of 5 of the boxes, multiply 2673.25 by 5.

2673.25 × 5 = 13366.25

Thus, the volume of 5 of the boxes is 13366.25in cubed.

A box of oranges has a mass of 4 kg. If one orange is 80 g, how many oranges are in the box?

Answers

Total mass of box = 4 kg or 4000 grams

Number of oranges= 4000/80

= 50 oranges

Answer:

50 oranges are in the box

Step-by-step explanation:

First, find the converting of 1 kg to grams (1kg = 1000g)

Then, convert how many kg is the box of oranges (4kg = 4000g)

Finally, divide the total grams of the box by the total grams per EACH orange in the box (4000g ÷ 80g = 50)

Therefore, there are 50 oranges in the box

Johnny runs a hot dog stand. On Wednesday morning, he had 32 dozen hot dogs at his stand. The graph shows the number of hot dogs (in dozens) that remained unsold at the end of each day of sales.

Answers

I saw you got it in the comment section of the post, but yes, he sold 30 dozen hot dogs on Wednesday.

By using the information of the graph, we conclude that he sold 2 dozen (24 hot dogs) on Wednesday.

How many hot dogs did Johnny sell on Wednesday?

The graph shows how many dozens of hot dogs Johnny had at the end of each day.

We know that he started with 32 dozens, and in the graph, we can see that at the end of Wednesday he had a total of 30 dozens.

Then the amount that he sold that day is:

32 dozens - 30 dozens = 2 dozens.

On Wednesday, he sells 2 dozen of hot dogs.

|z-7|-|z-9| if Z is less than 7

Answers

Answer:

If z<7, then z-7 is negative, and |z-7| is positive.  So, with the understanding that z-7 is positive, the first part of this expression becomes:

7-z for z<7

Similarly:  if z<7, then z-9 is negative and |z-9| is positive.  Thus, -|z-9| is equivalent to (9-z).

|z−7|−|z−9|, if z<7 becomes (7-z) - (9-z) for z<7.  Simplifying this, we get:

7 - z - 9 + z = -2

7 - z - 9 + z = -2

A pack of cinnamon-scented pencils sells for $5.00. What is the sales tax rate if the total cost of the pencils is $5.35?

Answers

Answer: $0.35

Step-by-step explanation:

Answer: 7%

Step-by-step explanation:

Ok, we'll start by listing the facts.

Facts

Pack of pencils is $5

Total cost: 5.35

This means the sales tax is 35 cents, but we need to find the percentage to get the sales tax rate.

We can do this by dividing .35 by 5

0.35÷5= 0.07

Convert 0.07 to a percentage by multiplying it by 100

0.07x100= 7

Hence the sales tax rate is 7%. We can check to make sure this is correct by finding 7% of 5, and then adding the result to the 5.

7% of 5= 0.35

5+0.35= 5.35
