Whitepunk [10]

You are describing where I live only that temperature is a bit low. I'm sorry to say it is neither one.

t_daily = t_average +/- 5

The highest temperature would be

t_daily = t_average + 5

t_daily = 1 + 5

t_daily = 6

================

The Lowest temperature would be

t_daily = t_average - 5

t_daily = 1 - 5

t_daily = - 4

Sounds about right for December.

Rina8888 [55]
Yards= 42  2/3 yd=42 + 2/3 yd=(42*3 + 2)/3 yd=128/3 yd
Gallons=1  1/3 Gallons=1+1/3 gallons=(3*1+1)/3 gallons=4/3 gallons.

Rate=number of yards / number of gallons.

Geometry question<br> Please help answer
Bess [88]

Answer:

Step-by-step explanation:

m∠1 = 2x and m∠2 = -3x+235

angle 1 and angle 2 are supplementary angle so they add up to 180°

m∠1 +m∠2 = 180°

2x -3x+235 = 180°

-x = 180-235

x=35

m∠1 = 2x = 2*35 = 70°

m∠2 = -3x+235 = -3*35 +235 = 235-105 = 130°
