5. 146.195
6. 159.84
B. 12 in.
C. square root 189 in.
D. square root 261 in
Answer: C. square root 189 in.
Step-by-step explanation:
Given : The length of the hypotenuse of a right triangle is 15 in.
The length of one leg = 6 in.
Let x be the length of other leg, then
According to Pythagoras theorem ,we have
Hypotenuse² = Perpendicular² + Base²
Hence, the length of the other leg is
Thus , the correct answer is C. square root 189 in.

Step-by-step explanation:
12-inch diameter costs $8.64, how much
should a pizza with a 16-inch diameter cost?
Answer: A 16 inch pizza is $11.52
Step-by-step explanation:
$8.64 / 12 = $0.72
$0.72 x 16 = $11.52
Take the amount ($8.64) and divide it by 12 (for the 12 inch pizza) and you get $0.72 for every inch of the pizza.
Then take $0.72 and times it by 16 (for the 16 inch pizza) and you get $11.52 and there is your answer.
Direct proportionality is used here to find the cost of a 16-inch pizza. Each inch of diameter costs $0.72, so a 16-inch pizza will cost $11.52.
The cost of a pizza in this instance is directly proportional to its diameter. Whenever such a situation arises, we use the concept of 'ratios' to determine the unknown value. In this particular question, the ratio of cost to diameter is the same for both pizzas.
The pizza with a 12-inch diameter costs $8.64, implying that every inch of diameter costs $8.64/12, or $0.72. If a 16-inch pizza is bought, the cost would then be 16 * 0.72, or $11.52.
