Answer:
38/100
Step-by-step explanation:
To combine the amounts, add the fractions with a common denominator.
3/10 kilogram flour is 30/100.
8/100 kilogram of sugar.
Both now have the same denominator. Add the numerators to find the total.
30/100 + 8/100 = 38/100
Let h = amount of hours
Since they earn $7.50 per hour, we can multiply that by an unknown amount of hours to get $116.25. Let's solve:
Divide both sides by 7.5 to isolate the h, amount of hours.
Simplify.
In conclusion, someone would have to work 15.5 hours to earn $116.25 if they earn $7.50 per hour.
I don't know the answer but my tip would be to split the shape the way I did it, find the lengths of each side, and then find the area for each individual shape.
Then add all the areas together.
2,700 / 12 = 225
225 / 5 = 45
