How do you solve 4/45 + 7/10

1 answer:

3 0

To solve it, you need to find the greatest common denominator. so 10 and 45 are both factors of 90. so then you have to multiplying the denominator and numerators of both fractions to make them both of 90.
4/45 (multiply the denominator by 2 to get 90, and what you do the bottom you have to do to the top, so 4×2)
4/45 = 8/90
7/10 = 63/90

then just add the two fractions together. 8/90+63/90=71/90

so the answer is 71/90

Hope this helped!!

Kyle Forman worked 47 hours during the week for Erickson Company at two different jobs. His pay rate was $14.00 for the first 40

LenKa [72]

one-half average method means there is bonus which is equivalent to over time * half of average hourly rate.

Let us calculate earnings using normal method first.

We are given that 14$ paid for first 40 hours and $11.8 for next 7 hours.

So, net pay would be 14*40+11.8*7 = $642.6

Now we need to find bonus pay using one-half rate method.

That bonus = over time * half of the average hourly rate

Average hourly rate = income earned/total number of hours

= $\frac{642.6}{47} = $13.67$

Hence bonus = 7* $\frac{13.67}{2}$ = $47.85

Gross pay using one-half average method= net pay + bonus

=642.6+47.85

= 690.45$

graph the function f (x)=x4 -7x2 on the interval x=-3 to x=3 which of the following best describes the graph from left to right

ch4aika [34]

Answer:

when graphing f(x) between x=-3 & x=3, the result is a function that comes from x=-infinite and positive y, crosses the x-axis at (-2.646,0), continues to decrease until (-1.871,-12.25) and then increases until (0,0).

This function is symetrical by the y axis, therefore, after reaching (0,0), f(x) decreases until (1.871,-12.25), starts to increase until it crosses the x axis at (2-646,0) and continues to increase until x=+infinite

Step-by-step explanation:

This funcion appears as a large W, with it's points on (-1.871,-12.25) , (0,0) & (1.871,-12.25)
