What numbers have an absolute value of 9

Answers

-9 and 9 because of you look on a number line -9 and 9 are 9 numbers away from 0.

The numbers that have an absolute value of 9 are 9 and -9.

In general, the absolute value of a positive number x is |x| = x, and the absolute value of a negative number -x is |x| = -(-x) = x.

So, for any number x or -x where x ≠ 0, its absolute value is always positive and equal to the positive value of "x."

The absolute value of a number is the distance of that number from zero on the number line.

Since both 9 and -9 are 9 units away from zero, their absolute values are both 9.

Hence, the numbers are 9 and -9.

No, just keep factoring until you cannot factor any further.

I could also start with 15*6, 3*30 or whatever. but the final answer will still be

No. as long as you factor out until you get to numbers that can't be factored you're fine. For example if you're factoring out 36 you can start with 18 and 2 or 12 and 3 or 4 and 9 and still end up with the factorization of 2•2•3•3

Jill collects stamps. her stamp book has space for 64 stamps she needs 18 more stamps to fill the book how many stamps does Jill have now

Answers

You need to subtract, but Jill has 46 stamps

Final answer:

Using subtraction, we determined that Jill currently has 46 stamps in her stamp book by subtracting the 18 stamps she needs to fill it from the total stamp book capacity of 64.

Explanation:

Jill's stamp collection problem is a simple subtraction problem in mathematics. To find out how many stamps Jill currently has, we subtract the number of stamps she needs to fill the book from the total capacity of the stamp book. If the stamp book has space for 64 stamps and she needs 18 more stamps to fill the book, we can calculate the number of stamps she currently has by doing the following calculation:

Total stamps space - Stamps needed = Stamps Jill has

64 - 18 = 46 stamps

Therefore, Jill currently has 46 stamps.

X-42=-33 what is the solution ?

Answers

x = -33 + 42
x = 42 - 33
x = 9
-42 + x = =33↓

-42 + 42 + x which is also equals to x = -33 + 42↓

-42 + 42 →0;  0 + x → -33 + 42; x  = -33 + 42 ↓

If you add these to from each other -33 + 42 it would equal to "9"

Therefore, "x" = 9 :) 

A parachutist's rate during a free fall reaches 135 miles per hour. What is this rate in feet per second? At this rate, how many feet will the parachutist fall during 2 seconds of free fall? In your computations, use the fact that 1 mile is equal to 5280 feet. Do not round your answers. THANK YOU!!!

Answers

1 mile = 5280 feet 135*5280=712,800
135 miles per hour = 712,800 feet per second
712,800+712,800= 1,425,600 feet per 2 seconds

The parachutist will free fall 1,425,600 feet in 2 seconds.

Answer:

Parachutist will fall 396 feet in 2 seconds.

Step-by-step explanation:

A parachutist's rate during a free fall reaches 135 miles per hour.

We have to calculate this rate in feet per second.

Rate = 135 [tex]\frac{miles}{hour}[/tex]

= 135×[tex]\frac{5280}{60\times 60}=135\times \frac{5280}{3600}[/tex] feet per second

= 135×1.467 feet per second

= 198 feet per second

Now we have to calculate the fall of the parachutist during 2 seconds.

Fall = 198×2 = 396 feet

Quincy is using 320 pieces of stone tile to make red white and blue mosaic. If 20% of the pieces are blue and 35% are white how many pieces are red?

Answers

100% = 320
20% = Blue tiles
35% = White Tiles
100% - 55% = Red Tiles = 45%
45% of 320
320 x 0.45 = 144 Red tiles
Final answer:

To determine the number of red tiles in Quincy's mosaic project, the percentage of blue and white tiles were converted to actual numbers and subtracted from the total. This calculation revealed that there are 144 red tiles.

Explanation:

Quincy is using 320 pieces of stone tile to make a mosaic.

It is given that 20% of the pieces are blue, and 35% are white. To find out how many tiles are red, we start by calculating the number of blue and white tiles:

Blue tiles: 20% of 320 = (20/100) * 320 = 64 tilesWhite tiles: 35% of 320 = (35/100) * 320 = 112 tiles

Adding the blue and white tiles together gives us 64 + 112 = 176 tiles.

Since the total number of tiles is 320, the number of red tiles will be the remaining tiles after subtracting the blue and white tiles:

Red tiles = Total tiles - (Blue tiles + White tiles) = 320 - 176 = 144 red tiles.

Therefore, 144 pieces of stone tile are red in Quincy's mosaic project.

We know that Pam spends 45 minutes going to work and 60 minutes when go to home from work. And we are told to write the ratio of minutes spent on driving from home to work to minutes spent on driving to home from work.

Going to work => 45
Going back to home => 60

Easy. 45:60 or 45/60. Now like a fraction, we must simplify. Find two numbers that will evenly divide into both top and bottom.

15 should do.

45/60 / 15/15 = 3/4

The scale on Krystal's map is 1 inch = 18 miles. How far apart are Greenville from north valley?

Answers

According to Krystal's map scale, the distance between Greenville and North Valley is 72 miles.

To find the distance between Greenville and North Valley using Krystal's map scale of 1 inch = 18 miles, you need to determine the distance represented by the two locations on the map and then convert it to real-world miles.

First, measure the distance between Greenville and North Valley on the map. Let's say it's 4 inches.

Now, multiply the measured distance on the map by the scale factor:

4 inches * 18 miles/inch = 72 miles.

Thus, according to Krystal's map scale, the distance between Greenville and North Valley is 72 miles.

This means that in reality, Greenville and North Valley are 72 miles apart.

This calculation is based on the given scale and assumes that the map accurately represents the geographical locations of Greenville and North Valley.

Always consider real-world conditions and factors like road layouts when planning actual travel.
