Answer:
( 5 - 2t ) < - 4
Step-by-step explanation:
The midnight temperature is 5 °C and the temperature is decreasing at the rate of 2°C per hour.
If t is the hours past midnight then after t hours the temperature will be ( 5 - 2t ).
Now, if this temperature is colder than - 4° C, then the inequality can be written as ( 5 - 2t ) < - 4 (Answer)
Answer:
yellow : 8
Red : 4
Step-by-step explanation:
Yellow : Y and Red : R
R : Y = 12
They need to add up to 12 because its the total.
We know that yellow is twice the amount so
4×2= 8
so if yellow was to be times by 2 itd be 8 which will still add up to 12.
Legend:
300 square feet = 1 gallon
Samples:
roof length = 63ft long
roof width = 47ft wide
Formula for area of the roof:
Area of the roof = (Length of the roof) x (Width of the roof)
A= 63 ft X 47 ft
A= 2961 feet
1 gallon = 300 ft
? gallon = 2961 ft
2961 ft / 300 ft per 1 gallon = 9.87 (cancelling out feet it leaves you gallons)
Answer is 9.87 gallons
