A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 5% off." If Roger buys two shirts, each with a regular price of $36, how much money will he save?
| $18.00 | |
| $7.20 | |
| $1.80 | |
| $3.60 |
By buying two shirts, Roger will save $36 x \( \frac{5}{100} \) = \( \frac{$36 x 5}{100} \) = \( \frac{$180}{100} \) = $1.80 on the second shirt.
\({b + c \over a} = {b \over a} + {c \over a}\) defines which of the following?
distributive property for multiplication |
|
commutative property for multiplication |
|
commutative property for division |
|
distributive property for division |
The distributive property for division helps in solving expressions like \({b + c \over a}\). It specifies that the result of dividing a fraction with multiple terms in the numerator and one term in the denominator can be obtained by dividing each term individually and then totaling the results: \({b + c \over a} = {b \over a} + {c \over a}\). For example, \({a^3 + 6a^2 \over a^2} = {a^3 \over a^2} + {6a^2 \over a^2} = a + 6\).
The __________ is the greatest factor that divides two integers.
greatest common multiple |
|
absolute value |
|
least common multiple |
|
greatest common factor |
The greatest common factor (GCF) is the greatest factor that divides two integers.
What is the next number in this sequence: 1, 7, 13, 19, 25, __________ ?
| 37 | |
| 33 | |
| 31 | |
| 35 |
The equation for this sequence is:
an = an-1 + 6
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 + 6
a6 = 25 + 6
a6 = 31
What is (a4)3?
| a12 | |
| a7 | |
| a | |
| 3a4 |
To raise a term with an exponent to another exponent, retain the base and multiply the exponents:
(a4)3
