Answer:
151 degrees
Step-by-step explanation:
This triangle has supplementary angles, so we need the triangle to add up to 180 degrees.
Start off with 61 degrees, below the 61 degrees symbol, there is a right angle under it, a right angle equals to 90 degrees. Then subtract 90 from 61, so the last angle is 29 degrees.
Then subtract 180 from 29, then your answer is 151 degrees.

Answer:
A
Step-by-step explanation:
A is correct. We're going from fractional power (1/3) to the corresponding radical equivalent (∛5).
Answer:
Step-by-step explanation:
In the normal distribution curve, the mean is in the middle and each line to the left and to the right of that mean represent 1- and 1+ the standard deviation. If our mean is 400, then 400 + 50 = 450; 450 + 50 = 500; 500 + 50 = 550. Going from the mean to the left, we subtract the standard deviation and 400 - 50 = 350; 350 - 50 = 300; 300 - 50 = 250. We are interested in the range that falls between 350 and 450 as a percentage. That range represents the two middle sections, each containing 34% of the data. So the total percentage of response times is 68%. We are looking then for 68% of the 144 emergency response times in town. .68(144) = 97.92 or 98 emergencies that have response times of between 350 and 450 seconds.
