Answer:
95$
Step-by-step explanation:
Alli sells 5 bars, for each bar she earnd 5$ so she earns 5*5=25$
Janet sells 7 mugs, and for every mug she earns 10$ (twice then Alli), so she earns 7*10=70$
Together: 25+70=95$
Answer:
$323
Step-by-step explanation:
Hello! First you would need to divide $171 by 9 to see how much money she makes an hour....
$171 / 9 = $19 an hour
Now that you know how much she makes an hour, multiply that amount by 17 to find out how much money she will make if she works for 17 hours.
$19 * 17 = $323
She will make $323 if she works for 17 hrs. :)
Hope this helps!

There can be so many of such.
Eg. 38 750 38 835
38 795
38 820
Any of the numbers above when rounded to the nearest hundred would result in 38 800.
The idea is such that to make sure the 100 digit is 7 and the 10 digit is 5 or more.
Or if the 100 digit is already 8, then the 10 digit must be less than 5
Answer: 20 ways
Step-by-step explanation:
Given: There were 5 women, 4 men, 6 girls and 7 boys at a birthday party.
i.e. Number of women = 5
Number of men = 4
According to the fundamental counting principle , we have
(Number of women ) x (Number of men)
= 5 x 4
= 20
Hence, 1 woman and 1 man can be chosen in 20 ways to take coats.
For this case we have the following polynomial:
The first thing to do is to place the variables on the same side of the equation.
We have then:
We complete the square by adding the term (b / 2) ^ 2 on both sides of the equation.
We have then:
Rewriting we have:
Therefore, the solutions are:
Answer:
the solution set of the equation is:
