Hey, I know the correct answer is C. May someone please explain or give me an example why the answer is C.

makvit [3.9K]

Answer:

3ny

Step-by-step explanation:

For this problem, the price of a widget is represented by 'n' amount of dollars. Additionally, the store was stocked with 4y widgets.

To find the total cost of the widgets sold, we will use the information that at the end of the day, the store only had y widgets remaining.

From here we can say the following to represent the total cost of the widgets sold:

cost = n * (4y - y)

cost = n * (3y)

cost = n3y

You can rewrite this cost to be 3ny as in the answer choice.

Cheers.

This figure is made up of a quadrilateral and a semicircle.

Arturiano [62]

Answer:

The correct option is B. The area of the figure is 40.4 units².

Step-by-step explanation:

The line AB divides the figure in two parts one is a rectangle and another is semicircle.

The distance formula is

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

The length of AB is

$AB=\sqrt{(2+3)^2+(4-2)^2}=\sqrt{25+4}=\sqrt{29}$

The length of AD is

$AD=\sqrt{(-1+3)^2+(-3-2)^2}=\sqrt{4+25}=\sqrt{29}$

Since AB=AD, therefore ABCD is a square. The area of the of square is

$A_1=a\times a=\sqrt{29}\times \sqrt{29} =29$

The area of square is 29 units².

The area of a semicircle is

$A_2=\frac{\pi}{2}r^2$

Since AB is the diameter of the semicircle, therefore the radius of the semicircle is

$r=\frac{d}{2}=\frac{\sqrt{29}}{2}$

The area of the semicircle is

$A_2=\frac{3.14}{2}(\frac{\sqrt{29}}{2})^2=40.3825$

The area of the figure is

$A=A_1+A_2=29+11.2825=40.3825\approx 40.4$

Therefore the area of the figure is 40.4 units². Option B is correct.

5/3 means (5 over 3 since I can't do fractions on this) 5/3-3/3=___ 5-3=2 first you do the numerators You keep the denominator the same since both denominators are 3 Then you put it together and get 2/3 and since 2/3 can't be reduced, 2/3 is the answer
