Answer:

To multiply a number by 0.01 move the decimal point 2 places to the left.

Step-by-step explanation:

for example, lets multiply 5 by 0.01

5 x 0.01=0.05

originally, 5 in decimal form is 5.0

when it is multiplied by 0.01, the decimal point moves first from 5.0 to 0.5, then 0.5 to 0.05

To multiply a number by 0.01 move the decimal point 2 places to the left.

A numeral system is a way of writing numbers; it's a way of mathematically notating a set of numbers by using a consistent set of digits or other symbols. In various numeral systems, the same set of symbols may represent various numbers.

For example, let's multiply 5 by 0.01

500 x 0.01 = 5

When the number 500 is multiplied by 0.01, the decimal point moves first from 500 to 5 means two places to the right.

Therefore, multiply a number by 0.01 and move the decimal point 2 places to the left.

Answer:

Step-by-step explanation:

For this problem, it says that the company not only shipped packages, but also bought a number of stamps. From the equation 6.70+0.50x, it's fairly easy to say that 6.70 is the packages,

What's not so easy is figuring out whether or not 0.50 is the stamps, or x is. However, there's an easy way to figure it out!

From this one, we would have to use "common sense" (not my words, someone elses). Using "common sense", we have to think, can someone buy 0.50 of a stamp?

Technically yes... But would someone buy 0.5 of a stamp? Not really.

So we can safetly assume that x is the "stamp", and 0.50 is the cost of the stamp.

Hope this helps!

Answer:

Step-by-step explanation:

The systems of equation for the scenario given are :

Cost per tacos = 4.50

Cost per burritos = 7.75

Total amount made = $519.25

Let :

Amount of burritos sold = t

Amount of tacos sold = 2t

Total amount made from burritos sale :

(Number of burritos sold × cost per burrito) = (t × 7.75) = 7.75t

Total amount made from tacos sale :

(Number of tacos sold × cost per tacos ) = (2t × 4.50) = 9t

Total amount made :

7.75t + 9t = 519.25

Answer:

Step-by-step explanation:

This might be easier to do in decimals. Let's try it.

3/5 = 0.6

1/10 = 0.1

rate = holes / hours

rate = 0.6/0.1

rate = 6 holes per hour

Try it with fractions.

rate =       [tex]\frac{\frac{3}{5} }{\frac{1}{10} }[/tex]    Invert and multiply the 1/10

rate =  [tex]\frac{3}{5} *\frac{10}{1}[/tex] = 30/5 = 6

It's the same answer. Pick the method that you feel most comfortable with.

Answer:

3x, -45, -w

Step-by-step explanation:

We want to simplify this expression to find which terms there are.

x - 53 - 4x - w + 6x + 8

We can group the x's, w's and constants.

(x - 4x + 6x) + (-53 + 8) + (-w)

3x - 45 - w

The terms are, 3x, -45, -w

Answer is 3x-w-45 how did I get the answer.

1. steps: x- 53 - 4x - w + 6x + 8

2. Steps: Group like terms x - 4x + 6x - w -53 + 8

3. Steps: Addsimilar elements: x - 4x + 6x = 3x

= 3x - w - 53 + 8

4. Steps: Add/Subtract the numbers: - 53 + 8 = -45

= 3x - w -45

That is your answer for this problem.

Step-by-step explanation:

We are given:

[tex]i^{4n+2}[/tex]

Using exponent properties:

[tex]=i^{4n}\cdot i^2[/tex]

Rewriting:

[tex]=(i^4)^n\cdot i^2[/tex]

Since i⁴ = 1 and i² = -1:

[tex]=(1)^n\cdot -1[/tex]

1 to any power is still 1:

[tex]=1\cdot -1 = -1[/tex]

Answer: It will take approximately 21 years.

Step-by-step explanation:

6 percent of 5.25 is 0.315 (5.25 x 0.06 = 0.315)

Then you subtract 5.25 from 12 to calculate the number of years. (12 - 5.25 = 6.75)

Divide 0.315 from 6.75 (6.75 / 0.315 ≈ 21.4)

Answer:

L (4,-5)

Step-by-step explanation:

The transformation rule is (x,y) → (-y,-x) . This means that you are going to exchange your x and y and switch their signs.

1. Exchange - First you switch your points. (5,-4) → (-4,5)

2. Switch signs- -4 converts to 4 and 5 converts to -5

So your answer is L' (4,-5)

Answer:

[tex]\frac{3b}{a} = 210[/tex]

Step-by-step explanation:

Explanation:-

Given that  a× 70 = b

Dividing 'a' into both sides, we get

           ⇒ [tex]\frac{b}{a} = 70[/tex]

we have to find the value [tex]\frac{3b}{a}[/tex]

       [tex]\frac{3b}{a} = 3 X \frac{b}{a}[/tex]

          = 3× 70

         = 210
