1. Joe received an hourly wage of $8.15. His boss gave him a 7% raise. How
much does Joe make per hour now?
(a) $0.57
(b) $8.90
(c) $8.72
(d) $13.85 - ANSWER ✔ C.To calculate the new wage first multiply
$8.15 × 0.07 = $0.57. Then add that to the original wage,
$8.15 + $0.57 = $8.72
2. Dana receives $30 for her birthday and $15 for cleaning the garage. If she
spends $16 on a CD, how much money does she have left? - ANSWER ✔
A. $29
B. $27
C. $24
D. $12
(A) Add the amount of money received and subtract the amount
spent. $30 + $15 - $16 = $29.
,3. In a manufacturing plant that produces new computers, a 0.15 probability
exists that a computer will be defective. If five computers are manufactured,
what's the probability that all of them will be defective? - ANSWER ✔ A.
7.6
B. 0.60
C. 0.000076
D. 0.00042
(C) The probability that all five computers will be defective is 0.15 × 0.15 ×
0.15 × 0.15 × 0.15 = 0.0000759 (round up to 0.000076).
4. simplifying fractions (reducing) - ANSWER ✔
writing fractions in lower terms
5. Adding and Subtracting fractions- ANSWER ✔
Fractions must share a common denominator in order to be added or subtracted.
The common denominator is the least common multiple of all the denominators
6. Multiplying and Dividing fractions- ANSWER ✔
To multiply fractions, multiply the numerators together and then multiply the
denominators together. To divide fractions, invert the second fraction ( get the
reciprocal and multiply it by the first.
7. Defining exponents- ANSWER ✔
,An exponent (cb^e) consists of coefficient (c) and 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)
8. Adding or Subtracting exponents- ANSWER ✔
To add or subtract terms with exponents, both the base and the exponent must
be the same. If the base and the exponent are the same, add or subtract the
coefficients and retain the base and exponent. For example 3x^2 + 2x^2 = 5x2
and 3x^2 - 2x^2 = x2 but x^2 + x^4 and x^4 - x^2 cannot be combined.
9. Multiplying and Dividing Exponents- ANSWER ✔
To multiply terms with the same base, multiply the coefficients and add the
exponents. To divide terms with the same abse, divide the coefficients and
subtract the exponents. For example For example, 3x^2 x 2x^2 = 6x^4 and
8x^5/4x^2 = 2x(5-2) = 2x3
10.Exponent to a power- ANSWER ✔
To raise a term with an exponent to another exponent, retain the base and
multiply the exponents: (x^2)^3 = x^(2*3)=x^6
11.Negative exponent- ANSWER ✔
A negative exponent indicates the number of times that the base is divided by
itself. To convert a negative exponent to a positive exponent, Calculate the
positive exponent then take the reciprocal. b^−e = 1/b^e. For example, 3^−2 =
1/3^2 = 1/9
12.defining radicals- ANSWER ✔
Radicals (or roots) are the opposite operation of applying exponents. With
exponents, you're multiplying a base by itself some number of times while with
roots you're dividing the base by itself some number of times. A radical term
looks like d√r and consists of a radicand (r) and a degree (d). The degree is the
number of times the radicand is divided by itself. If no degree is specified, the
degree defaults to 2 (a square root)
, 13.Simplifying Radicals- ANSWER ✔
The radicand of a simplified radical has no perfect square factors. A perfect
square is the product of a number multiplied by itself (squared). To simplify a
radical, factor out the perfect squares by recognizing that √a^2 = a. For
example, √64 = √16×4 = √4^2 * 2^2 = 4×2 = 8.
14.Adding and subtracting radicals- ANSWER ✔
To add or subtract radicals, the degree and radicand must be the same. For
example,2√3 + 3√3 = 5√3 = but 2√2 + 2√3 cannot be added because they have
different radicands.
15.Multiplying and dividing radicals- ANSWER ✔
To multiply or divide radicals, multiply or divide the coefficients and radicands
separately: x√a * y√b = xy√ab and x√a / y√b = x/y√a/b
16.Square root of a fraction- ANSWER ✔
To take the square root of a fraction, break the fraction into two separate roots
then calculate the square root of the numerator and denominator separately. For
example, √9/16 = √9 / √16 = 3/4
17.Scientific notation- ANSWER ✔
Scientific notation is a method of writing very small or very large numbers. The
first part will be a number between one and ten (typically a decimal) and the
second part will be a power of 10. For example, 98,760 in scientific notation is
9.876 x 104 with the 4 indicating the number of places the decimal point was
moved to the left. A power of 10 with a negative exponent indicates that the
decimal point was moved to the right. For example, 0.0123 in scientific notation
is 1.23 x 10-2.
