Answer:
It's a function that associates a real number x with a positive real number using the flowing definition: If the number is not negative (so either positive or 0) the absolute value is x. If x is negative, the absolute value is -x.
This means that to find the absolute value of x you must first determine if x is negative or not, and if it is, multiply it by -1. If it isn't, leave it as it is.
Since the absolute value is a function (of a given number), you can't just plot that number in the number line but the function (so in this case absolute value must be taken first.
The absolute value of x is never negative, so given the absolute value of x we can't determinate if x was positive or negative (if x =/ 0) before the absolute value was taken.

Answer:
See Below
Step-by-step explanation:
Lets look at our numbers:
The balloon is at 1000 feet.
The balloon drops at a constant speed of -4 1/2 per second.
How long will it take to get to 215ft, in seconds, s.
Lets see, if you were to subtract 1000-215, you will get 785.
The balloon needs to drop 785ft to get to 215ft above the ground.
The question asks how long will it take to get below 215ft.
Lets do the math for the descending feet. We calculated that it takes 785ft to hit 215ft above the ground, so, you need to divide 785ft by 4 1/2 to see how many seconds it takes. The answer for this is 174.4, we can make this 174 4/9.
**VERY IMPORTANT** If you use 174 4/9, this equals 215 seconds, it asks for below this, so you can use ANY number for this that it above this number.
Now for the inequality, look at the question, it asks how long will it take to get below, not equal to or more below, meaning that you can cancel out the inequality signs with lines below them. So your answer is 270 > ,

Step-by-step explanation:
A 6-pound bag of sugar costs $7.98. What is the unit price?
Answer:
1.33
Step-by-step explanation:
Lets start by making a quick equation:
Total cost is y, or 7.98, with the weight being 6 pounds. We are looking for the unit price, which will be our x.
7.98 = 6x
Divide 6 by both sides:
7.98 / 6 = 6x / 6
This gets rid of the 6 on the right, so we are left with:
1.33 = x
So the unit price is $1.33 per pound.
I hope this helps! :)
Jake is wrapping a gift that is in a box with the following dimensions.
Length: 12 inches
Width: 4 inches
Height: 8 inches
Havana is wrapping a gift whose box's dimensions are all twice the length of the lengths in Jake's box.
How many times larger is the surface area of Havana's box than Jake's box?
Enter your answer as a number, like this: 42
HELP PLEASEEEEEEEE
Answer: 8
Step-by-step explanation: first multiply 12x4x8 for jakes gift. that is 384
then make each of the dimensions twice as large. so havanas dimensions would be. 24x8x16
24x8x16=3,072
last divide 3,072 by 384 and the answer would be 8
Havana's box is 8 times larger.

Susan opened a college savings account 4 years ago. She opened the account with an initial deposit of $3,000. Starting the next year, she deposited $1,000 on the same day each year. The account earns interest at an annual rate of 4.15% and is compounded annually. Susan hopes to have earned enough interest to pay for her first year of college tuition, which costs $7,100. What is the difference between her ending balance after 4 years and the cost of her tuition?
Answer:
$20
Step-by-step explanation:
multiply 100.00 x 5% which is 100x 0.05, then it will give you 5.
add 5, 4 more times which will give you 20

Find the volume of a scented candle that is in the shape of a cylinder with a diameter of 16 centimeters and a height of 20 centimeters. Round to the nearest tenth.
*there is no diagram*
Answer:
4021.2 cm³
Step-by-step explanation:
you start by getting the radius, the radius is half the diameter which in this case half of 16 is 8 so 8 is your radius and you already know the height which is 20, now that we have the radius and the height we can start
the formula for finding the volume of a cylinder is πr² · h
so are formula would be π8² · 20 which turns into π64 · 20 which then turns into 1280π or 4021.238...
which you then said we need to round the nearest tenth so 4021.238 to the nearest tenth is 4021.2 cm³
