Answer:

x = 5

Step-by-step explanation:

You have a right triangle, so you can use the Pythagorean Theorem.

a^2 + b^2 = c^2

x^2 + 12^2 = 13^2

x^2 + 144 = 169

x^2 = 25

x = 5

Answer: x = 5

9. Find the coordinates of point C along line segment AE with A(-2,-4) and
Nana76 [90]

Answer:

C = (4,-1)

Step-by-step explanation:

Given

A = (-2,-4)

E = (8,1)

AC:CE = 3:2

Required

Determine the coordinates of C

This is calculated as follows;

C = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})

Where:

(x_1,y_1) = (-2,-4)

(x_2,y_2) = (8,1)

m:n = 3:2

So, we have:

C = (\frac{3 * 8 + 2 * -2}{3+2},\frac{3 * 1 + 2 * -4}{3+2})

C = (\frac{24 -4}{5},\frac{3-8}{5})

C = (\frac{20}{5},\frac{-5}{5})

C = (4,-1)

Ms. Wendie puts 4 chocolate candies in a bag to give each of her students on the first day of class. She puts a total of 76 choc
Alchen [17]
This scenario is all about creating equal groups of 4 candies.  Because we know the total number of candies that were used, the 4 is a part and we are missing the other part(groups).  We can think of it as how many groups of 4 will result in 76.  This is shown in Choice A.

the volume of a gas varies inversely as the pressure upon it. if the volume of the gas is 160 cubic centimeters at a pressure of
marin [14]
It was stated in the problem that a given volume of a is inversely proportional with the pressure of the system. It means that the as the volume increases, the pressure would decrease and as the volume decreases, the pressure would increase. We would express it as:

V α 1/P

To change it to an equality, we introduce a proportionality constant, k. We do as follows:

V = k/P

So, to determine what is asked, we need to first calculate for the value of k.

V = k/P
At V = 160 m^3 P = 108 cmHg
160 = k / (108)
k = 17280

Thus, at P = 87 cmHg 
V = 17280 / 87 
V = 198.62 m^3
