What is the area of trapezoid ABCD ?

Bumek [7]

AD = 5
BC = 15
AB = 5

Area = 1/2(AD + BC)*AB
Area = 1/2(5 + 15)(5)
Area = 1/2(20)(5)
Area = 50

A fence is to be built to enclose a rectangular area of 210 square feet. The fence along three sides is to be made of material t

Serhud [2]

Answer with explanation:

Let the length of rectangular fence = x meters

Let the width of the rectangular fence = y meters

Thus

$Area=x\times y=210ft^{2}...........(i)$

Now Let the total cost to construct the fence be 'C' can be obtained if we construct the shorter side with material with cost $12 per foot

$\therefore C=5\times (2y+x)+12\times x\\\\C=10y+17x...............(ii)$

Using value of x from the equation i into equation ii we get

$C=10y+17\times \frac{210}{y}$

hence to minimize the cost we differentiate both sides with respect to 'y' and equate the result to zero thus we get

$C=10y+17\times \frac{210}{y}\\\\\frac{dC}{dy}=\frac{d}{dy}(10y+\frac{3570}{y})\\\\0=10-\frac{3570}{y^{2}}\\\\\therefore y=\sqrt{\frac{3570}{10}}=18.894feet$

Thus $x=\frac{210}{18.894}=11.11feet$

Thus value of length = 11.114 feet and value of width = 18.894 feet.

6 friends share 5 oranges equally. What fraction of an orange does each friend get?

Yuki888 [10]

Because you have more friends than oranges, you can assume that each person will only get part (or a fraction of) an orange.
If you divide 5 oranges for 6 people, your equation looks like 5 / 6, so each person gets 5/6th of an orange, or about 0.833 oranges per person.

Hope this helps :)
