Answer:
The answer to your question is 10 units ²
Step-by-step explanation:
To solve this problem I will use the formula
3 3
A = 1/2 3 -1 = 1/2 [ (3 x -1) + (3 x -5) + (-2 x 3) - (3 x -5) - (-2 x -1)
-2 -5 -(3 x 3)]
3 3 = 1/2 [ -3 - 15 - 6 + 15 - 2 - 9]
= 1/2 [ -20]
= 1/2|20|
= 10 units²
Sorry, I don't remember how to use the formula 1/2 b x h
To find the temperature after 5 minutes you will find the rate of change that occurred in the first minute and apply that to the next 5 minutes.
The temp drops 13 degrees (20-7) after 1 minute, so it will drop 13 more minutes the next minute (7-13= -6 degrees)
Another 13 the next minute (-6-13=-19), BUT it will not drop below the actual air temp.
The thermometer should be at -15 degrees after 5 minutes.
If one gallon equals 4 quarts then the first part of the equation would be 4+
Next, if you have 2 quarts of paint, the equation would become 4+2
And lastly, if you have 3 pints of red paint, that would become 1.5 quarts. So your final equation would be 4+2+1.5= 7.5 quarts of paint.
Final answer: 7.5 quarts
Answer:
122 ft^2.
Step-by-step explanation:
This area can be divided into 2 rectangles:
One of size 14 * 4 = 56 ft^2 and
another of size (15 - 4)* 6 = 66ft^2
Total 66 + 56 = 122 ft^2.
