HELP One morning in Atlanta, Tina observed that the temperature was 72 degrees. Later the temperature rose 21 degrees and then dropped 11 degrees. She then flew to New York where the temperature was 67 degrees.
What was the change in temperature from when Tina left Atlanta and arrived in New York?
A
5°
B
6°
C
14°
D
15°

D

Step-by-step explanation:

72+21-11=82

82-67=15

The Correct Answer is option D.

Step-by-step explanation:

Tina observed that the temperature was 72 degrees. Later the temperature rose 21 degrees and then dropped 11 degrees.

That is, 72+21-11=82.

She then flew to New York where the temperature was 67 degrees.

The change in temperature from when Tina left Atlanta and arrived in New York is,

82-67=15.

Hence, the change in temperature is 15.

Thus, the correct option is D.

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
