Use the formula for the area of a triangle, and fill in the given information.
.. A = (1/2)*b*h
.. 36 in^2 = (1/2)*b*(9 in)
.. (72 in^2)/(9 in) = b . . . . . . . . multiply by 2, divide by 9 in
.. 8 in = b
The base is "none of the above", 8 inches.
_____
This question has a couple of problems:
.. 1) area is not measured in "inches"; it is measured in "square inches."
.. 2) ALL of the offered answer choices are INCORRECT.
Answer:
Step-by-step explanation:
Information that we know about the square:
side length: 
which can asol be expressed as: 
we can use this information to calculate the area by the formula for the area of a square:
we subtitute the side length:
the square root and the squared exponent cancel each other out (because they are opposite operations) and since this is an area it must have squared units:
The exact value of the area of the square is 
Answer:
20
Step-by-step explanation:
60% is 3/5 as a fraction
so i divided 12 by 3 and got 4
to find the whole u times 4 by 5 equals 20
Answer: $310,000
Step-by-step explanation:
In 40 additional years, the amount she made less than her college counterparts was;
= 10,000 * 40
= $400,000
She however made $90,000 more than them as they went to college;
= 400,000 - 90,000
= $310,000
The long-term financial cost was $310,000.
