10 members of a bridal party need transported to a wedding reception but there are only 2 4-passenger taxis available to take them. How many will need to find other transportation?
| 8 | |
| 9 | |
| 3 | |
| 2 |
There are 2 4-passenger taxis available so that's 2 x 4 = 8 total seats. There are 10 people needing transportation leaving 10 - 8 = 2 who will have to find other transportation.
How many 15-passenger vans will it take to drive all 39 members of the football team to an away game?
| 6 vans | |
| 12 vans | |
| 5 vans | |
| 3 vans |
Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:
vans = \( \frac{39}{15} \) = 2\(\frac{3}{5}\)
So, it will take 2 full vans and one partially full van to transport the entire team making a total of 3 vans.
Which of the following statements about exponents is false?
b1 = b |
|
b0 = 1 |
|
b1 = 1 |
|
all of these are false |
A number with an exponent (be) consists of a base (b) raised to a power (e). The exponent indicates the number of times that the base is multiplied by itself. A base with an exponent of 1 equals the base (b1 = b) and a base with an exponent of 0 equals 1 ( (b0 = 1).
What is \( \frac{63\sqrt{8}}{9\sqrt{4}} \)?
| \(\frac{1}{2}\) \( \sqrt{\frac{1}{7}} \) | |
| \(\frac{1}{2}\) \( \sqrt{7} \) | |
| \(\frac{1}{7}\) \( \sqrt{2} \) | |
| 7 \( \sqrt{2} \) |
To divide terms with radicals, divide the coefficients and radicands separately:
\( \frac{63\sqrt{8}}{9\sqrt{4}} \)
\( \frac{63}{9} \) \( \sqrt{\frac{8}{4}} \)
7 \( \sqrt{2} \)
A bread recipe calls for 2\(\frac{7}{8}\) cups of flour. If you only have \(\frac{1}{8}\) cup, how much more flour is needed?
| \(\frac{1}{4}\) cups | |
| 2\(\frac{3}{4}\) cups | |
| 2 cups | |
| \(\frac{3}{8}\) cups |
The amount of flour you need is (2\(\frac{7}{8}\) - \(\frac{1}{8}\)) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{23}{8} \) - \( \frac{1}{8} \)) cups
\( \frac{22}{8} \) cups
2\(\frac{3}{4}\) cups
