Answer:

0.3992

Step-by-step explanation:

8.0x10^-4=0.0008

4.0x10^-1=0.4

0.4-0.0008=0.3992

How do we find percent of increase

Answers

Answer:

See explanation and example below.

Step-by-step explanation:

To find percent increase you must know the original amount and the new amount. Then use the formula below:

percent increase = (new amount - old amount)/(old amount) × 100%

Example:

A book used to cost $10. Then the price increased to $12. What is the percent increase?

Given information:

old amount = $10

new amount = $12

Percent increase formula:

percent increase = (new amount - old amount)/(old amount) × 100%

Apply the given information to the formula:

percent increase = ($12 - $10)/($10) × 100%

percent increase = $2/$10 × 100%

percent increase = 0.2 × 100%

percent increase = 20%

Answer: The percent increase from $10 to $12 is 20%.

Answer:

Increase = Increase / The original Number * 100

Step-by-step explanation:

Don't worry I gotchu!

You basically divide the amount that is progressing, i.e, or that is, the increase of the number by the original number and then multiply by 100. SO thats how you find the percent of increase! Sry if i stated another formula but i think it is the right one. sry if i am wrong :(

Lova and her family are dividing 82 books into 4 boxes to donate to homeless shelters. They would like to put the same number of books in each box. Is this possible? Explain.

Answers

Answer: no, it would not be possiable. Because if you divide 82 by 4, then you would get 20.5, and you cant split a book to put in other boxes.

Answer:

No, it is not possible, unless they keep 2 books out.

Step-by-step explanation:

To find out how many books to put in each box you can divide 82 into 4 groups:

82 ÷ 4 = 20.5

You cannot have half of a book, so no, it is not possible to put the same number of books in each box, unless they keep 2 books out.

The only way this would work is if they had 80 books instead of 82 books.

GEOMETRY Find the perimeter and the area of the polygon with the given vertices.


I just need help with this.. IT MAKES NO SENSE!!!:D

Answers

Answer:

Perimeter: 12

Area: 9

Step-by-step explanation:

Use the distance formula to find the length of each side of the polygon, then you add all of the sides together. the distance formula is square root (x2-x1)^2+(y2-y2)^2 (you can just look up distance formula if you want a visual). The length between (1,1) and (4,1) is 3,  the length between (4,4) and (4,1) is also 3, the length between (1,4) and (4,4) is also 3, and the length between (1,4) and (1,1) is also 3. Add up all those lengths to get the perimeter. To find the area, its just length times width. So instead of adding all the sides like perimeter, you just do 3 times 3

Write the word sentence as an equation. Then solve the equation.

Answers

Answer: n - 4 = -15

n = -11

Step-by-step explanation:

If -15 is the same as 4 less than n, that means that n - 4 = -15

Then you add 4 to each side of the equation to get n by itself. (-15 + 4 = -11)

That step leaves you with n = -11

Answer:

n - 4 = -15

N= -11              -11 - 4 = -15

Step-by-step explanation:

n − 4 + 4 = −15 + 4

n = −11

no you can’t add them, but you can do this: 7x+7 =0

No, you can’t because, to simply algebraic expressions the numbers or letters or coefficients need to be the same. 7x have a number with a letter but, the +7 only have the number. In other words, the letters and/or the exponents (in this one there’s no exponent but I’m just putting an example) need to be the same in order to combine them

HELP! Two right rectangular prisms are shown below. If each prism is packed with small cubes of side length 1/4 inch how many more cubes are in prism 2


A. 42 Cubes B. 48 Cubes

C. 510 Cubes D. 720 Cubes

Answers

Answer:

First find the volume of the two rectangular prisms using the formula:

V = l · w · h

Where 'l' represents the length, 'w' the width, and 'h' the height.

Now let's find the volume of Prism 1;

V = l · w · h

V = 7/4 · 3/2 · 5/4

V = (7/4 · 3/2) · 5/4

V = 21/8 · 5/4

V = 105/32 cubic inches.

Now let's find the volume of Prism 2;

V = l · w · h

V = 5/2 · 9/4 · 2

V = (5/2 · 9/4) · 2

V = 45/8 · 2/1(make 2 to 2/1 because it makes it a bit easier)

V = 90/8 cubic inches.

Now let's find how many cubes can fit into each of these prisms.

But first, we need to find out the volume of one cube.

Remember, all sides to a cube are equal.

Using the formula, V = l · w · h;

1/4 · 1/4 · 1/4

= 1/64 cubic inches is the volume of one cube.

Now we find how many cubes can fit inside each of these prisms.

Prism 1:

105/32(volume for this prism) ÷ 1/64(volume of one cube)

= 210 cubes can fit inside prism one.

Prism 2:

90/8(volume for this prism) ÷ 1/64(volume of one cube)

= 720 cubes can fit inside prism two.

Finally, let's calculate their difference:-

720 - 210

= 510 cubes.

Hence, prism 2 can hold 510 more cubes than prism 1.

Answer: D


Explanation: to find the volume of the cone you would have to use the formula:

1/3* pi* r^2* h
If the dimensions are to be plugged in the formula would then be

1/3* 3.14* 4^2 * 12

Therefor the volume of the cone is 201.06 in^3

Moving on to the cylinder, the formula used would be

V=Bh

To find B the formula used would be

B= pi* r^2

Plugged in the formula would turn unto

B= 3.14* 3^2

The volume of the cylinder is 226.19

When subtracted, the area if the cylinder is about 25 cubic inches less than the cone, so the answer is D.
