Hey,
So if you are working 8 hrs a day and $15 an hour multiply those together, that would give you $120 a day, and multiplying that by 5 days a week that would make $600 a week.

Paul borrowed $360 to be repaid in one year. He paid 10% interest and a service
Art [367]

Answer:

Step-by-step explanation:

Hey, do you mean what is the final charge? If so, then look at my next steps

If you mean the final charge then first multiply 10% by 360 , basically 10/100 multiplied by $360 which is equals to $36. Since it is interest, add $36 to $360. The answer will be $396. Then you add on the $19 which would bring the total to $415.

Hehe I am no expert but this is what I did . Tried my best

A printing company charges $42 plus $0.05 per page. Another company just charges $0.08 per page. How many pages are in an order
Nookie1986 [14]
There should be 1,400 pages in an order that costs the same for both companies.

Let x be the unknown number of pages.

1st Company = 42 + 0.05x
2nd Company = 0.08x

0.08x = 42 + 0.05x
0.08x - 0.05x = 42
0.03x = 42
0.03x / 0.03 = 42 / 0.03
x = 1400 pages

To check

0.08x = 42 + 0.05x
0.08 (1400) = 42 + (0.05 * 1400)
112 = 42 + 70
112 = 112

For each of the functions below, indicate whether the function is onto, one-to-one, neither orboth. If the function is not onto
Karo-lina-s [1.5K]

Answer:

f_{1} :Z \rightarrow Z is one to one mapping, it is not onto mapping

Step-by-step explanation:

f_{1} :Z \rightarrow Z\\ f_{1} (x) = x^{3}

f₁(x) is one to one mapping

Let x, y \epsilon Z

f₁(x) = f₁(y):

x₁³ = y₁³

f₁(x) is not onto mapping

Example: If f₁(x) = 7,

x₁³ = 7

x_{1} = \sqrt[3]{7}

x₁ is not an element of Z

f_{1} :Z \rightarrow Z is one to one mapping, it is not onto mapping
