Answer:
A) We know that she make $7 per hour, with this we can make a table:
1hr | $7
2hr | $14
3hr | $21
etc...
B) If in one week she earns $105 and 1w = 7h (1hr = $7) holds true, that means that we have to divide 105 by 7 which gives us 15hrs
C) If she baby-sat for 24hrs, we just have to multiply that by 7 and we get $168
Hope that helped!
I'm assumig you meant ?=pi
so the area of the sector would be the area of the circle times the fraction of the circle that is
the fraction of the circle would be degrees/360 since 360 degrees in a circle
and area of course is pir^2
so
r=8
degrees=120
so
area=pi8^2 times 120/360
area=64pi times 1/3
area=64pi/3
I think you mean 64/3 pi in²
so D is the answer
Rounding to the nearest million is just looking at the 100,000's place, and seeing if it's bigger than 5 or not. if it is you round to the number up to the next million and if it's not you round the number down to to the same million. In your case it rounds up to 2,000,000 because of the the 100,000's place is a 5 so you round up
