For the answer to the question above, <span>f x is the number of days she works, she'll earn $90x </span>
<span>After buying the laptop, she'll have $90x - $700 left over, which will pay for ($90x - $700) / $150 days of travel. So we have y = ($90x - $700) / $150 = (9x - 70) / 15 = 0.6x - (14/3) </span>
<span>Note that y can't be negative. Also, if y = 0, then Emma doesn't get to travel at all, so we should avoid that. So we have: </span>
<span>0.6x - (14/3) > 0 </span>
<span>0.6x > 14/3 </span>
<span>x > (14/3) / 0.6 </span>
<span>x > 70/9 </span>
<span>The question says that x can be up to 40, so the domain is 70/9 < x <= 40 </span>
<span>That's approximately 7.777... < x <= 40 </span>
<span>Multiply those numbers by 0.6 and then subtract 700 to get the range: </span>
<span>0 < y <= 58/3 </span>
<span>That's approximately 0 < y <= 19.333</span>

Answer:
100cm, 1m are equal to 0.001km
Step-by-step explanation:
0.001 is 1 thousandths and a kilometer is 1,000 meters so it would be 1m/1000m, 100 centimeter because one meter is one hundred centimeters.
Answer:
176.4
Step-by-step explanation:
1.) 7/5 = surface area/90 = (7/5)^2 = 49/25
2.) sa/90 = 49/25
3.) 4,410/25a
Surface area is 176.4
Hope this helps!
Answer:
11.6%
Step-by-step explanation:
On the first selection, there are 20 red pencils out of 42 total pencils.
On the second selection, there are 10 green pencils out of 41 pencils left over.
So the probability is:
(20/42) (10/41)
100/861
≈11.6%
