A. 6 B. 9 C. 12 D. 15 ## Best ASVAB Math Prep Resource for 2021 ## Answers: 1- B Perimeter of a rectangle = $$2 × length + 2 × width$$ = $$2 × 90 + 2 × 30 = 180 + 60 = 240$$ 2- B $$Speed =\frac{distance}{time }$$ $$16.2=\frac{distance}{2.1}⇒ distance=16.2×2.1=34.02$$ Rounded to a whole number, the answer is $$34$$. 3- B Let’s review the choices provided and find their sum. $$a. 20 × 6 = 120$$ $$b. 26 × 6 = 144$$ ⇒ is greater than 120 and less than 180 $$c. 30 × 6 = 180$$ $$d. 34 × 6 = 204$$ Only choice b gives a number that is greater than 120 and less than 180. 4- A $$120 – 12 = 108$$ $$\frac{108}{12} = 9$$ 5- C percent of change = $$\frac{change}{original \space number}$$ $$7.75 – 7.50 = 0.25$$ percent of change = $$\frac{0.25}{7.50}$$ = 0.0333 $$⇒ 0.0333 × 100 = 3.33\%$$ 6- B Two candy bars costs 50¢ and a package of peanuts cost 75¢ and a can of cola costs 50¢. The total cost is: $$50 + 75 + 50 = 175$$ 175 is equal to 7 quarters. $$7 × 25 = 175$$ 7- C Every day the hour hand of a watch makes 2 complete rotation. Thus, it makes 16 complete rotations in 8 days. $$2 × 8 = 16$$ 8- B $$30\% × 50 =\frac{30}{100} × 50 = 15$$ The coupon has$15 value. Then, the selling price of the sweater is \$35.
$$50 – 15 = 35$$
Add $$5\%$$ tax, then:
$$\frac{5}{100} × 35 = 1.75$$ for tax
then:
$$35 + 1.75 = 36.75$$

9- D
Use FOIL (First, Out, In, Last) method.
$$(x + 7)(x + 5) = x^2 + 5x + 7x + 35 = x^2 + 12x + 35$$

10- D
In scientific notation form, numbers are written with one whole number times 10 to the power of a whole number. Number 670,000 has 6 digits. Write the number and after the first digit put the decimal point. Then, multiply the number by 10 to the power of 5 (number of remaining digits). Then:
$$670,000 = 6.7 × 10^5$$

11- C
Perimeter of a triangle = side 1 + side 2 + side 3 $$= 25 + 25 + 25 = 75$$

12- A
From the choices provided, 36, 48 and 54 are divisible by 6. From these numbers, 54 is the biggest.

13- A
Oven 1 = 4 oven 2
If Oven 2 burns 3 then oven 1 burns 12 pizzas.$$3 + 12 = 15$$

14- C
An obtuse angle is an angle of greater than $$90^\circ$$ and less than $$180^\circ$$.

15- B
5231.48245 rounded to the nearest tenth equals 5231.5
(Because 5231.48 is closer to 5,231.5 than 5,231.4)

16-A
Diameter = 16
Area of a circle =$$πr^2$$ ⇒ $$A = 3.14(8)^2 = 200.96$$

17- A
$$7! = 7 × 6 × 5 × 4 × 3 × 2 × 1$$

18- C
Let’s review the choices provided. Put the values of $$x$$ and $$y$$ in the equation.
A. $$(1, 2) ⇒ x = 1 ⇒ y = 2$$ This is true!
B. $$(−2, −13) ⇒ x = -2 ⇒ y = -13$$ This is true!
C. $$(3, 18) ⇒ x = 3 ⇒ y = 12$$ This is not true!
D. $$(2, 7) ⇒ x = 2 ⇒ y = 7$$ This is true!

19- C
Use distance formula:
$$d=\sqrt{((x_1-x_2)^2+(y_1-y_2)^2 )} = \sqrt{((1-(-2))^2+(3-7)^2 )}$$
$$\sqrt{(9+16)} = \sqrt{25} = 5$$

20- B
$$(x^2 \space – \space 81 = 0 ⇒ x^2 = 81 )$$ ⇒ $$x$$ could be $$9$$ or $$–9$$.
