You use the equation given to solve the problem.

x= 4x9
X=36
The four is for the amount of people. The nine is the cost.

For the questions where you have to find out how much each person paid you would have to divided the amount by the number of people.

So, 36/9= 4.30

Therefore each person paid $4.30.

(Hope this helps you)

In a class of 29 students, 19 are female and 14 have an A in the class. There are 8students who are male and do not have an A in

masya89 [10]

SOLUTION

The total number of females =

$19$

if 14 have an A in the class, the number of students without A is:

$29-14=15$

8 male students do not have an A, therefore the number of female students without an A is:

$15-8=7$

The probability that a student does not have an A given that the student is female can be calculated thus:

$\frac{\text{Total number of female students without an A}}{Total\text{ number of female students in the class}}$ $\frac{7}{19}$

Find the area A of the polygon with the given vertices.

Natalija [7]

Answer:

A = 35 square units

Step-by-step explanation:

Formula to calculate the distance between two points $(x_1,y_1)$ and $(x_2,y_2)$ is,

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

Length of the segment between A(2, 2) and B(9, 2) = $\sqrt{(9-2)^2+(2-2)^2}$

= 7 units

Length of the segment between B(9, 2) and C(9, -3) = $\sqrt{(9-9)^2+(2+3)^2}$

= 5 units

Length of the segment between C(9, -3) and D(2, -3) = $\sqrt{(9-2)^2+(-3+3)^2}$

= 7 units

Length of the segment between A(2, 2) and D(2, -3) = $\sqrt{(2-2)^2+(2+3)^2}$

= 5 units

Therefore, given polygon is a rectangle.

Area of the rectangle = length × width

= 7 × 5

= 35 square units
