The daily mean temperature in a particular place is 83. how many cooling-degree days were accumulated?

1 answer:

4 0

Degree days are the difference between the daily temperature mean, (high temperature plus low temperature divided by two) and 65°F. 65°F because we assume that at this temperature we do not need cooling or heating.
In our case the daily mean temperature is 83°F and X is the number of cooling-degree days.
X=83-65
X=18

Answer:

180 miles

Step-by-step explanation:

Don drove (50 mi/h)×(2 h) = 100 mi.

Frank drove (40 mi/h)×(2 h) = 80 mi.

Since they drove in opposite directions, the total distance between them is

100 mi +80 mi = 180 mi.

F ∠A is 95° and ∠B is 105°, what is ∠C?<br> A) 75° <br> B) 85° <br> C) 95° <br> D) 105°

Jobisdone [24]

The question is missing important data. The quadrilateral having vertices A, B, C and D is a cyclic quadrilateral.

Answer:

B) 85°

Step-by-step explanation:

Given:

A cyclic quadrilateral with ∠A is 95° and ∠B is 105°.

For a cyclic quadrilateral, the sum of the opposite interior angles is equal to 180°

Therefore, sum of angles A and C is 180°.

$\angle A + \angle C=180\°\\95\°+\angle C=180\°\\\angle C=180-95\\\angle C =85\°$

Therefore, the correct option is option B) 85°
