One morning, the temperature was -5 ferenhight. By noon, the temperature had increased 12 degrees. What was the temperature at noon? Use a model to explain your answer.

Step-by-step explanation:

Given

Initial Temperature = -5F

Change (by noon) = 12 degrees

Required

Determine the temperature at noon

The temperature by noon is calculated as thus;

Substitute values for Initial temperature and change

Hence, the temperature at noon is 7F

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
