Answer:
cosR = 
Step-by-step explanation:
assuming the right triangle has ∠ Q = 90° with legs 5 and 12
then this is a 5- 12- 13 right triangle with hypotenuse PR = 13 cm
then
cosR = 
= 
=
Answer:
True.
Step-by-step explanation:
It fails the vertical line test. The vertical line test checks to see if any inputs (x values) have more than one output. In this case, they do.
Answer: The answer to this problem is 178 calories.
Step-by-step explanation:
To calculate the answer, simply get the percentage of calories a person would burn during exercise (I am using a calculator BTW).
185 / 260 = 0.711538462
Then, calculate 71.1538462% of 250 pounds.
250 * 0.711538462 = 177.884616
Finally, round up your answer. 177.884616 rounded up is 178.
