Which of the following statements about exponents is false?
b1 = 1 |
|
all of these are false |
|
b1 = b |
|
b0 = 1 |
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).
A bread recipe calls for 2\(\frac{7}{8}\) cups of flour. If you only have 1\(\frac{1}{4}\) cups, how much more flour is needed?
| 1\(\frac{1}{4}\) cups | |
| 2 cups | |
| 1\(\frac{5}{8}\) cups | |
| 2\(\frac{3}{8}\) cups |
The amount of flour you need is (2\(\frac{7}{8}\) - 1\(\frac{1}{4}\)) cups. Rewrite the quantities so they share a common denominator and subtract:
(\( \frac{23}{8} \) - \( \frac{10}{8} \)) cups
\( \frac{13}{8} \) cups
1\(\frac{5}{8}\) cups

How many 10-passenger vans will it take to drive all 79 members of the football team to an away game?
| 7 vans | |
| 8 vans | |
| 12 vans | |
| 4 vans |
Calculate the number of vans needed by dividing the number of people that need transported by the capacity of one van:
vans = \( \frac{79}{10} \) = 7\(\frac{9}{10}\)
So, it will take 7 full vans and one partially full van to transport the entire team making a total of 8 vans.
