A human hair was measured to be 8.0 × 10^−4 inch thick. A cat hair was measured to be 4.0 × 10^−1 inch thick. How much greater is the thickness of the cat hair than the human hair? Write the answer in standard form.

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 :(

Answer: 9375

Step-by-step explanation: 32/100 = 3000

x = 3000 x 100/32

x = 9375

Answer <3

Hello there! I'm here to help with your question!

I believe the answer is x= 6

The explanation:

9 = [tex]\frac{3}{2}[/tex] x

9 =[tex]\frac{3x}{2}[/tex]

9 = [tex]\frac{3x}{2}[/tex]

2 · 9 = · [tex]\frac{3x}{2}[/tex]

2 · 9 = 2 · [tex]\frac{3x}{2}[/tex]

2 · 9 = 3x

x = 6

Answer:

B.) The large bowl was spicier




Small bowl:
5 : 20 = 1 : 4

1 ounce of pepper for every 4 ounces of tomatoes.




Larger bowl:
6 : 30 = 1 : 5

1 ounce of pepper for every 5 ounces of tomatoes.

Step-by-step explanation:

Have a great rest of your day
#TheWizzer

Answer:

I think they are the same amount of spicy. C)

Step-by-step explanation:

This is because he used a larger amount of peppers but also a larger amount of tomatoes so if it is not B) it would be C) because they seem as though they could also be the same amount of spicy due to the amounts of each ingredient used.

I hope this helped!

Answer:

24

Step-by-step explanation

50% chance to roll a prime number

Answer:

it would be 24 times

Step-by-step explanation:

so lets think the prime numbers on a six sided dice are 2, 3 and 5 so there is a 50% chance to roll a prime number and she wanted to roll 12 a prime number 12 times and with a 50% chance so we figure out what 50% of ? = 12 witch is 24 so there is your answer hope i could help if you could mark me brainlyist i would love it if not thats fine have a good day (or night) :)

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.

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:

x = 3

Step-by-step explanation:

12 * (3) = 36. 36 / 12 = (3)

Answer:

x = 3

Step-by-step explanation:

soo all you have to do is make x alone, to do that you have to divide 12 to both sides.

12x / 12 = 36/12

x = 3

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

Hey there! Hope you are having a fantastic day!

To find the volume of a Prismatic Rectangle you must multiply all three sides together. In your case, It would be 4 x 2 x 1. Which would leave you with an answer of 8.

Hope this helps! :)

Answer:

Hi! I answered a question like this yesterday so I will help!

First let's read carefully: Write an inequality to show the age of citizens who ARE allowed to run for mayor.

Part A:

If x ≥ 21, they can vote; x is the age of the person that wants to vote!

Part B:

Mark a closed dot on 21 and an arrow pointing to the right. A closed dot means "greater than or equal to" or "less than or equal to". Marking this would mean that anybody 21 or older can vote.

Hope this helps! Mark the brainliest please!~

Hello!

If x (age person wants to vote) ≥ 21; they can vote.

Mark a closed dot on 21 and an arrow pointing to the right. A closed dot means "greater than or equal to" or "less than or equal to". Marking this would mean that anybody 21 or older can vote.

Part B credit to guy above me :F

Answer:

154

Step-by-step explanation:

The formula for the area is A=πr2

The line labeled 7 is the radium or the R in the formula

Replace 7 with R

A=π7(squared)

square seven

A=49π

pi is approximately 3.14

mutiply 7 by pi

A= 154

Answer:$13 to $14

Step-by-step explanation:

4.17= 4

3.19=3

2.86=3

3.75=4

Add them all up and you get 14.

Solve the actual equation to check your work

(Btw it equals 13.77 if you don't estimate)

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

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.
