Answer:

  • No, not enough time

Step-by-step explanation:

<u>Time to complete each of jobs</u>

  • 1/2 * 3 = 1 1/2 hrs
  • 3/4 * 1 = 3/4 hr
  • 1 1/2 * 2 = 3 hrs
  • 2 1/2 * 1 = 2 1/2 hrs

<u>Total time at job</u>

  • 1 1/2 + 3/4 + 3 + 2 1/2 = 7 3/4 hrs

If the work day lasts for 8 hours, then Lana has only 1/4 hr to travel between jobs and a lunch break.  

This time is not sufficient so she can't complete all the jobs.

Answer:

Yes there is plenty of time for her by my estimation

Step-by-step explanation:

total hours = 7.75 hrs

7 hours plus 45 mins

30 break 15 travel per job

15 * 7 = 105 mins

135 total

total = 9.5 hours

Answer:

H=310

Step-by-step explanation:

This problem is a great systems of equations problem--you have two different variables: song size and number of songs.

Let's call the number of standard version downloads (S) and the high quality downloads (H).

You can make two statements:

For number of songs downloaded: S + H = 910

For download size: 2.8(S) + 4.4(H) = 3044.

S will be the same number in both equations and H will be the same number in both equations, so to find S, we can rearrange the first statement to H = 910 - S, then substitute or plug in (910 - S) wherever you see an H in the second equation so that you have only S's in your equation. Should look like this:

2.8(S) + 4.4(910 - S) = 3044

2.8S + 4004 - 4.4S = 3044

-1.6S = -960

s = 600

Your question only asks for the standard version downloads, but to help you out in future Systems situations-

You can also solve for H once you have S by plugging it into either of your equations like this:

600 + H = 910

-600

Hope this helps!

Select the best answer for the question. 17. 18 is what percent of 20? A. 10% B. 90% C. 18% D. 95%
vovangra [49]
Percent formula : is/of = %/100

18 is what percent of 20...
is = 18
of = 20
% = x

sub and solve
18/20 = x/100
cross multiply
(20)(x) = (100)(18)
20x = 1800
x = 1800/20
x = 90 <=== so 18 is 90% of 20

So first you would divide 1950/6 to find the amount for one year of their age.
Then you would multiply that by the ages, which should get you 4 numbers, then you all those numbers together. Try 9750.

Harish
Artist 52 [7]

Answer:

Step-by-step explanation:

Distance traveled in 1\frac{4}{5} hours = \frac{3}{10}

Distance traveled in 1 hour = \frac{3}{10} ÷ 1\frac{4}{5}

          =\frac{3}{10} ÷ \frac{9}{5}

          = \frac{3}{10}*\frac{5}{9}\\\\=\frac{1}{2}*\frac{1}{3}\\\\=\frac{1}{6}

distance traveled in 3 1/5 hours = \frac{1}{6}*3\frac{1}{5}

 ==\frac{1}{6}*\frac{8}{5}\\\\=\frac{1}{3}*\frac{4}{5}\\\\=\frac{4}{15}
