What is the distance in miles of a trip that takes 9 hours at an average speed of 30 miles per hour?
| 125 miles | |
| 270 miles | |
| 70 miles | |
| 120 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 = \( 30mph \times 9h \)
270 miles
Betty scored 78% on her final exam. If each question was worth 3 points and there were 120 possible points on the exam, how many questions did Betty answer correctly?
| 32 | |
| 43 | |
| 31 | |
| 28 |
Betty scored 78% on the test meaning she earned 78% of the possible points on the test. There were 120 possible points on the test so she earned 120 x 0.78 = 93 points. Each question is worth 3 points so she got \( \frac{93}{3} \) = 31 questions right.
What is the next number in this sequence: 1, 3, 7, 13, 21, __________ ?
| 31 | |
| 30 | |
| 36 | |
| 32 |
The equation for this sequence is:
an = an-1 + 2(n - 1)
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(6 - 1)
a6 = 21 + 2(5)
a6 = 31
If a car travels 30 miles in 1 hour, what is the average speed?
| 30 mph | |
| 45 mph | |
| 35 mph | |
| 40 mph |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:
speed = \( \frac{\text{distance}}{\text{time}} \)Charlie loaned Frank $1,500 at an annual interest rate of 5%. If no payments are made, what is the interest owed on this loan at the end of the first year?
| $56 | |
| $25 | |
| $2 | |
| $75 |
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 $1,500
i = 0.05 x $1,500
i = $75
