Question 1

Find 53% of 360^o Round your answer to the nearest tenth. A) 169.2^o B) 180.0^o C) 201.4^o D) 198.0^o E) 190.8^o

Accepted Answer

To find 53% of 360, we can multiply 360 by 0.53. This gives us 190.8, which rounds to 191 when rounded to the nearest whole number. However, we need to round to the nearest tenth, so we look at the digit in the hundredths place, which is 0. Since 0 is less than 5, we do not round up, and the final answer is 198.0. Therefore, the correct answer is D.

Question 2

Of 1,859 students, 210 are taking technical physics. What angle of a circle would show the percent of students taking technical physics? Round your answer to the nearest tenth. A) 40.7^o B) 32.5^o C) 43.8^o D) 34.9^o E) 21.9^o

Accepted Answer

To find the angle of a circle that represents the percent of students taking technical physics, we need to divide the number of students taking technical physics by the total number of students and then multiply by 360 degrees.(210 / 1,859) * 360 = 40.7 degrees (rounded to the nearest tenth)Therefore, the correct answer is A) 40.7^o.

Question 15

Of 5,000 TV sets, 227 are found to be defective. What angle of a circle would show the percent of defective TV sets? Round your answer to the nearest tenth.
A) $16.3 ^ { \circ }$
B) $15.8 ^ { \circ }$
C) $32.7 ^ { \circ }$
D) $16.0 ^ { \circ }$
E) $14.3 ^ { \circ }$

Accepted Answer

To find the angle, calculate the percentage of defective TVs: $ \frac{227}{5000} \times 100 \approx 4.54\% $. Then, convert this percentage to an angle: $ 4.54\% \times 360^\circ \approx 16.3^\circ $.
