How do you find the absolute value of a positive number ?

Answers

Answer 1
Answer: Absolute value is the distance a number is away from 0. What I do is just put the # down. Ex. The absolute value of 5 is 5. The absolute Value of 98624 is 98624.
Answer 2
Answer: this is how you do absolute value from positive to negative...
example: l25l = l25l              example: - l25l = l-25l                example: l-25l = l25l

Given a cylinder with a surface area of 2532 cm (squared) and radius of 9 cm, calculate the height of this cylinder to the nearest tenth.A. 36 cm
B. 282.6 cm
C. 45
D. 10

Answers

Answer:

A. 36.4cm = h

Step-by-step explanation:

A=2πrh+2πr²               This is the equation to find the surface area of a cylinder

2532 = 2π(9)h + 2π(9)²       Multiply

2532 = 18πh + 2π(81)          Multiply

2532 = 56.55h + 162π        Multiply

2532 = 56.55h + 508.94  

-508.94              - 508.94   Subtract 508.94 from both sides

2023.06 = 56.55h               Divide both sides by 56.55

36.4cm = h

5+(-2)=?

Answers

think of it as subtracting your adding a negative number to a positive, if the positive number is larger when adding, then your answer should end up positive if the negative number is larger your answer should be negative, in this case you could think of this problem as 5-2 instead of adding the 5 to the negative 2. so in this case your answer would be 3. if you don't get it try using a number line, those are very helpful when starting off!
Well,

5 + (-2)

"Five plus the quantity negative two."

Adding a negative quantity is the same as subtracting the positive quantity.

For example: 0 + (-1) = 0 - 1 = -1

Another situation: 0 - (+1)

You have to realize that any number (say 5, for example) without a sign in front of it is automatically positive.

Technically, if we "show signs," we will get +0 - (+1)

We can really just omit ("hide signs") the positive signs.
0 - 1 = -1

Yet another situation: 0 - (-1)

Subtracting a negative can be re-worded as "subtracting from the negative."  It sounds like it is taking away from the negative, bringing the integer closer to zero.  Subtracting a negative is the same as adding a positive.
0 - (-1) = 0 + (+1) or 0 + 1 = 1

In your case: 5 + (-2):
5 + (-2) = 5 - 2 or 3 or +3

chris is on a vacation at a lake house for the weekend and decided to rent a canoe for the day. they charge $10 service free plus $38 per hour and he can spend at most $200 how many hours can he rent the canoe

Answers

10 +38h < =200

subtract 10 from each side

38h < =190

divide by 38

h<=5

Answer:  They can rent at most 5 hours

$200 - the $10 fee leaves you  with $190 to spend with $38 per hour

divide 190 by 38 to get 5

you can rent the canoe for 5 hrs

Which expressions show the expanded form for 840.02? Choose all answers that are correct. 8 × 100 + 4 × 10 + 2 × 110 8 × 100 + 4 × 10 + 2 × 1100 8 × 100 + 4 × 10 + 0 × 1 + 0 × 110 + 2 × 1100 8 × 100 + 4 × 10 + 4 × 0 + 0 × 11 + 2 × 110

Answers

Answer:

Option B and C are correct.

8 * 100 + 4 * 10 +2 * (1)/(100)

8 * 100 + 4 * 10 + 0 * 1 + 0 *(1)/(10)+2 * (1)/(100)

Step-by-step explanation:

Find the expanded form of 840.02.

Any decimal number can be expanded in the form of power of 10.

then;

In 840.02

the first 8 is

8 hundreds i.e, 800 ,

4 is 4 tens i.,e 40 ,  

0 ones ,

0 one-tenths and

2 hundredths,

we can write this as;

840.02 = 800 + 40 + 0 * 1 + 0 * (1)/(10)+2 * (1)/(100)

or

8 * 100 + 4 * 10 +2 * (1)/(100)

or

840.02 = 8 * 100 + 4 * 10 + 0 * 1 + (0)/(10)+ (2)/(10^2)



Answer:

8 × 100 + 4 × 10 + 2 × 1/100

8 × 100 + 4 × 10 + 0 × 1 + 0 × 1/10 + 2 × 1/100

Step-by-step explanation:

8 × 100 + 4 × 10 + 2 × 1/10 =800+40+2/10 = 840+2/10 = 840.2

8 × 100 + 4 × 10 + 2 × 1/100 = 800+40+2/100 = 840+2/100 = 840.02

8 × 100 + 4 × 10 + 0 × 1 + 0 × 1/10 + 2 × 1/100 =800+40+2/100= 840.02

8 × 100 + 4 × 10 + 4 × 0 + 0 × 11 + 2 × 1/10=800+40+2/10= 840+2/10 = 840.2
