What is the distance in miles of a trip that takes 6 hours at an average speed of 30 miles per hour?
| 180 miles | |
| 150 miles | |
| 105 miles | |
| 315 miles |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:
speed = \( \frac{\text{distance}}{\text{time}} \)Solving for distance:
distance = \( \text{speed} \times \text{time} \)
distance = \( 30mph \times 6h \)
180 miles
A tiger in a zoo has consumed 117 pounds of food in 9 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 169 pounds?
| 7 | |
| 4 | |
| 12 | |
| 5 |
If the tiger has consumed 117 pounds of food in 9 days that's \( \frac{117}{9} \) = 13 pounds of food per day. The tiger needs to consume 169 - 117 = 52 more pounds of food to reach 169 pounds total. At 13 pounds of food per day that's \( \frac{52}{13} \) = 4 more days.
4! = ?
3 x 2 x 1 |
|
5 x 4 x 3 x 2 x 1 |
|
4 x 3 |
|
4 x 3 x 2 x 1 |
A factorial has the form n! and is the product of the integer (n) and all the positive integers below it. For example, 5! = 5 x 4 x 3 x 2 x 1 = 120.
What is the next number in this sequence: 1, 3, 5, 7, 9, __________ ?
| 8 | |
| 3 | |
| 11 | |
| 4 |
The equation for this sequence is:
an = an-1 + 2
where n is the term's order in the sequence, an is the value of the term, and an-1 is the value of the term before an. This makes the next number:
a6 = a5 + 2
a6 = 9 + 2
a6 = 11
