Marissa dug three fifths of a hole in one tenth of an hour. Find the rate
in holes per hour
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

Point L (5, -4) is reflected across the line y = -x using the transformation rule (x, y) --> (-y, -x). What is the ordered pair of the Image L''? Please write your response as (x, y),
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)

Fill in the blanks. To multiply a number by 0.01 move the decimal point ____ places to the _______. *
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.
What is a number system?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.

Why does the expression i to the power 4n+2 is always equal to -1
Answer:
See Below.
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]
A company ships packages through the postal service. One week, the cost of shipping one
package was $6.70, and the company also purchased a number of stamps. This can be
modeled by the expression 6.70 + 0.50x. According to the model, what is the meaning of
0.50?
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!

What are the terms in x - 53 - 4x - w + 6x + 8
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

Caroline uses 9.1 pints of blue paint and white paint to paint her bedroom walls. 1 4 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Answer:
6.83 pints
Step-by-step explanation:
The first step is to calculate the volume of the blue paint
= 9.1 × 1/4
= 2.275
Therefore the volume of the white paint can be calculated as follows
= 9.1 - 2.275
= 6.83
Hence the volume of white paint that Caroline used to paint her bedroom walls is 6.83 pints

Yesterday David made a total of $519.25 in revenue from all taco and burrito sales and there were twice as many tacos sold as there were burritos sold. Write a system of equations that could be used to determine the number of tacos sold and the number of burritos sold. Define the variables that you use to write the system. (Let statments and system of equations)
Answer:
Step-by-step explanation:
The systems of equation for the scenario given are :
7.75t9t7.75t + 9t = 519.25Cost 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
