Answer:
f(x) = 4x
Step-by-step explanation:
Verification:
f(2) = 4 x 2 = 8
f(3) = 4 x 3= 12
f(4) = 4x x 4 = 16
You have 1, 2, 3, 4, 5, and 6 on a dice. Only 2 of 6 are the rolls that you want. Therefore, it is 2/6, which simplifies to 1/3.
Answer:
5π or 15.71 inches
Step-by-step explanation:
Length of an arc = 
× 2πr
Where x is the angle and r is the radius
so 
× 2 × π × 10
0.25 × 2 × π × 10
Arc length = 5π inches (answer in terms of π)
= 15.71 inches (answer in two decimal places)
Answer:
10 hours lifeguarding, 6 hours tutoring
Step-by-step explanation:
As you know how long he worked and how much he earned, it's worth seeing how many hours it would have been had he worked just tutoring or just lifeguarding.
$242 / 11 = 22 hours if it was just lifeguarding
$242 / 22 = 11 hours (as it's exactly double the wage) if it was just tutoring
We now know that he worked some combination of both
Calculating his average wage can help work out which he worked more of:
$242 / 16 = 15.125
That means Parker's average hourly wage was 15.125 which is closer to 11 than 22 (16.50 would mean an exactly even split between the two) so he did more hours lifeguarding than tutoring so more than 8 hours.
What I then do is consider the variations that could work:
9 (lifeguarding) and 7 (tutoring) = 99 + 154 = 243
So we're almost exactly there straight away, but not quite so...
10 and 6 = 110 + 132 = 242
There you have it.
