$20 sold / .50(each flowers) = 40 flowers

She sold 40 flowers for $20

She makes $6 on every $20

$20 - $6 = $14 (she paid $14 for 40 flowers)

Each flower she paid = $14 / 40 = 0.35 (35 cents)

Answer:

She paid 35 cents per flower

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.

Which of the following is the equation for this graph?

ivolga24 [154]

Answer:

y=17/3x+2

Step-by-step explanation:

Get 2 points from the graph

(3;19) (-10;2)

Grad=change in y/change in x

=2-19/-10-3

=-17/-13

=17/3

y=mx+c

19=17/13(3)+c

19=17+c

19-17=c

2=c

y=17/13x+2.

Well I think you are supposed to find the equation of the line so I think that's it.

The is it mean, range, mode, or median of the following set of data is 6. 13, 7, 9, 5, 2, 3, 5, 4, 10, 12

grandymaker [24]

the way you have laid this question out is strange but im assuming you want me to find the mean, range, medium and mode of the numbers provided?

<h2>Answer:</h2>

median=order them and find the middle= 6

mean=add them all up and divide by the amount of numbers=(6+13+7+9+5+3+2+5+4+10+12)/11=6.9

range= the difference between the smallest and largest number=13-2=11

mode= the one that appears the most= 5

The equation of the line L is 2y-x=10.Find the coordinates of the point where L intersects the y-axis

Lapatulllka [165]

Equation:- 2y-x=10

For L to intersects Y axis then X cordinate must be zero

so put value of X as zero (0) :-

$2y - x = 10 \\ 2y - 0 = 10 \\ 2y = 10 \\ y = \frac{ \cancel{10}^{ \: \: \: 5} }{ \cancel2}$

So Y cordinate is equal to 5

Cordinate:- (0,5)
