a(b + c) = ab + ac defines which of the following?
distributive property for division |
|
commutative property for multiplication |

commutative property for division |
The distributive property for multiplication helps in solving expressions like a(b + c). It specifies that the result of multiplying one number by the sum or difference of two numbers can be obtained by multiplying each number individually and then totaling the results: a(b + c) = ab + ac. For example, 4(10-5) = (4 x 10) - (4 x 5) = 40 - 20 = 20.
If there were a total of 150 raffle tickets sold and you bought 4 tickets, what's the probability that you'll win the raffle?
| 15% | |
| 16% | |
| 4% | |
| 3% |
You have 4 out of the total of 150 raffle tickets sold so you have a (\( \frac{4}{150} \)) x 100 = \( \frac{4 \times 100}{150} \) = \( \frac{400}{150} \) = 3% chance to win the raffle.
What is (c4)5?
| c-1 | |
| c20 | |
| c9 | |
| c |
To raise a term with an exponent to another exponent, retain the base and multiply the exponents:
(c4)5Bob loaned Ezra $200 at an annual interest rate of 8%. If no payments are made, what is the interest owed on this loan at the end of the first year?
| $16 | |
| $72 | |
| $50 | |
| $45 |
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 $200
i = 0.08 x $200
i = $16
What is the next number in this sequence: 1, 5, 9, 13, 17, __________ ?
| 26 | |
| 21 | |
| 12 | |
| 13 |
The equation for this sequence is:
an = an-1 + 4
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 + 4
a6 = 17 + 4
a6 = 21
