A tiger in a zoo has consumed 60 pounds of food in 6 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 100 pounds?
| 4 | |
| 3 | |
| 2 | |
| 9 |
If the tiger has consumed 60 pounds of food in 6 days that's \( \frac{60}{6} \) = 10 pounds of food per day. The tiger needs to consume 100 - 60 = 40 more pounds of food to reach 100 pounds total. At 10 pounds of food per day that's \( \frac{40}{10} \) = 4 more days.
Which of the following is an improper fraction?
\({2 \over 5} \) |
|
\({a \over 5} \) |
|
\(1 {2 \over 5} \) |
|
\({7 \over 5} \) |
A rational number (or fraction) is represented as a ratio between two integers, a and b, and has the form \({a \over b}\) where a is the numerator and b is the denominator. An improper fraction (\({5 \over 3} \)) has a numerator with a greater absolute value than the denominator and can be converted into a mixed number (\(1 {2 \over 3} \)) which has a whole number part and a fractional part.
Bob loaned Charlie $1,300 at an annual interest rate of 3%. If no payments are made, what is the interest owed on this loan at the end of the first year?
| $8 | |
| $39 | |
| $4 | |
| $44 |
The yearly interest charged on this loan is the annual interest rate multiplied by the amount borrowed:
interest = annual interest rate x loan amount
i = (\( \frac{6}{100} \)) x $1,300
i = 0.03 x $1,300
i = $39
The total water usage for a city is 20,000 gallons each day. Of that total, 27% is for personal use and 54% is for industrial use. How many more gallons of water each day is consumed for industrial use over personal use?
| 6,750 | |
| 1,600 | |
| 3,850 | |
| 5,400 |
54% of the water consumption is industrial use and 27% is personal use so (54% - 27%) = 27% more water is used for industrial purposes. 20,000 gallons are consumed daily so industry consumes \( \frac{27}{100} \) x 20,000 gallons = 5,400 gallons.
