The absolute value of a number is how far away it is from 0 on a number line.
Example) 2 is two numbers away from 0, but neg. 2 (-2) is also two numbers away from 0
So basically. A positive number has the absolute value of itself. (2= a value of 2) and negative numbers have the absolute value of the positive form of that number. (-9= a value of 9)
Numbers that have the absolute value of 2: 2 and -2
Numbers that have the absolute value of 4: 4 and -4
Numbers that have the absolute value of 9: 9 and -9
You are looking to add your numbers together to make a positive.
So the answer is the positive answers to the absolute values: 2,4,9
2+4+9=15
15 is a positive number.
Answer:
The answer is c = 17 feet
Step-by-step explanation:
The formula to find the hypotenuse is a^2 + b^2 = c^2 (<em>a </em>squared plus <em>b </em>squared equals <em>c </em>squared).
<em>a </em>= 8 feet
<em>b </em>= 15 feet
<em>a</em>^2 = 8 * 8 = 64
<em>b</em>^2 = 15 * 15 = 225
The next step is to add: 64 + 225 = 289
But we need to remember to square root 289 because we squared <em>a </em>and <em>b</em>.
The square root of 289 equals 17
c = 17 feet
Answer:
The answer is $8.00.
Step-by-step explanation:
First, you have to find how much for each app so you have to divide by 3 :
3 apps = $2.40
1 app = $2.40 ÷ 3
1 app = $0.80
Next, you have to multiply it by 10 :
1 app = $0.80
10 apps = $0.80 × 10
10 apps = $8.00
In mathematics, whole numbers are the basic counting numbers 0, 1, 2, 3, 4, 5, 6, … and so on. 17, 99, 267, 8107 and 999999999 are examples of whole numbers. Whole numbers include natural numbers that begin from 1 onwards. Whole numbers include positive integers along with 0.
