1- C
The weight of 12.2 meters of this rope is: 12.2 $$×$$ 600 g = 7320 g
1 kg = 1000 g therefore,
7320 g $$÷$$ 1000 = 7.32 kg

2- 60
Jason needs an $$75\%$$ average to pass for five exams. Therefore, the sum of 5 exams must be at lease $$5 × 75 = 375$$
The sum of 4 exams is:
68 + 72 + 85 + 90 = 315
The minimum score Jason can earn on his fifth and final test to pass is:
375 – 315 = 60

3- A
It’s needed to have a ratio to find value of $$x$$.
$$\frac{45}{40}=\frac{2x+4}{16}⇒ 40(2x+4)=45×16 ⇒ x=7$$

4- D
Use Pythagorean Theorem: $$a^2 + b^2 = c^2$$
$$62 + 82 = c^2 ⇒ 100 = c^2 ⇒ c = 10$$

5- B
To find the discount, multiply the number by ($$100\% –$$ rate of discount).
Therefore, for the first discount we get:
(D) ($$100\% – 20\%) =$$ (D) (0.80) = 0.80 D
For increase of $$10%$$:
(0.80 D) ($$100\% + 10\%) =$$ (0.85 D) (1.10) = 0.88 D $$= 88\%$$ of D

6- A
Use PEMDAS (order of operation):
$$[6 × (– 24) + 8] – (– 4) + [4 × 5] ÷ 2 = [– 144 + 8] – (– 4) +  ÷ 2 = [– 144 + 8] – (– 4) + 10 = [– 136] – (– 4) + 10 = [– 136] + 4 + 10 = – 122$$

7- B
Use the formula of areas of circles.
Area $$= πr^2 ⇒ 64 π = πr^2 ⇒ 64 = r^2 ⇒ r = 8$$
Radius of the circle is 8. Now, use the circumference formula:
Circumference $$= 2πr = 2π (8) = 16 π$$

8- B
Use the formula for Percent of Change
$$\frac{New \space Value \ – \ Old \space Value}{Old \space Value}× 100\%$$
$$\frac{28-40}{40}× 100\% = – 30\%$$
(negative sign here means that the new price is less than old price).

9- C

The question is this: 1.75 is what percent of 1.25?
Use percent formula:

part $$= \frac{percent}{100}×$$ whole
$$\frac{percent}{100}× 1.25 ⇒ 1.75 = \frac{percent ×1.25}{100}⇒175 =$$ percent $$×1.25 ⇒$$ percent $$= \frac{175}{1.25}= 140$$

10- A
Let $$x$$ be the amount of students in the class.
$$40\%$$ of $$x =$$ girls
$$25\%$$ of girls = tennis \space player
Input $$40\%$$ of a class instead of girls in second formula. Therefore, $$25\%$$ of $$40\%$$ of a class = tennis player
tennis player $$= 10\%$$
