How many 12-passenger vans will it take to drive all 79 members of the football team to an away game?
| 8 vans | |
| 7 vans | |
| 6 vans | |
| 15 vans |
Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:
vans = \( \frac{79}{12} \) = 6\(\frac{7}{12}\)
So, it will take 6 full vans and one partially full van to transport the entire team making a total of 7 vans.
11 members of a bridal party need transported to a wedding reception but there are only 2 3-passenger taxis available to take them. How many will need to find other transportation?
| 2 | |
| 3 | |
| 8 | |
| 5 |
There are 2 3-passenger taxis available so that's 2 x 3 = 6 total seats. There are 11 people needing transportation leaving 11 - 6 = 5 who will have to find other transportation.
What is -b4 - 6b4?
| -7b-4 | |
| 7b4 | |
| -7b4 | |
| 5b-8 |
To add or subtract terms with exponents, both the base and the exponent must be the same. In this case they are so subtract the coefficients and retain the base and exponent:
-1b4 - 6b4
(-1 - 6)b4
-7b4
What is \( \frac{1}{9} \) ÷ \( \frac{4}{5} \)?
| \(\frac{5}{36}\) | |
| \(\frac{5}{9}\) | |
| \(\frac{4}{81}\) | |
| \(\frac{1}{15}\) |
To divide fractions, invert the second fraction and then multiply:
\( \frac{1}{9} \) ÷ \( \frac{4}{5} \) = \( \frac{1}{9} \) x \( \frac{5}{4} \)
To multiply fractions, multiply the numerators together and then multiply the denominators together:
\( \frac{1}{9} \) x \( \frac{5}{4} \) = \( \frac{1 x 5}{9 x 4} \) = \( \frac{5}{36} \) = \(\frac{5}{36}\)
Jennifer scored 94% on her final exam. If each question was worth 3 points and there were 210 possible points on the exam, how many questions did Jennifer answer correctly?
| 78 | |
| 74 | |
| 66 | |
| 67 |
Jennifer scored 94% on the test meaning she earned 94% of the possible points on the test. There were 210 possible points on the test so she earned 210 x 0.94 = 198 points. Each question is worth 3 points so she got \( \frac{198}{3} \) = 66 questions right.
