At a basketball game, a vender sold a combined total of 108 sodas and hot dogs. The number of sodas sold was three times the number of hot dogs sold. Find the number of sodas and the number of hot dogs sold.

Answers

Answer:

Hot dogs - 27, soda - 81

Step-by-step explanation:

Soda to Hot dog ratio = 3:1

If the total is 108, we can divide 108/4 ---> 27

now, multiply 3 and 1 by 27 and there you go!

edit: also if you don't know why I divided 108 by 4, its because you add together both sides of the ratio

153.8=3.14(r)squared

Answers

153.8 = 3.14r^2

Divide each side by 3.14 to get r alone.

48.9 = r^2

Take the square root of each side to isolate r.

r = 6.999

r= 7

r=12.27

153.8-3.14=150.66

150.66 square root is 12.27

B) parallel

C) horizontal and vertical

D) none of the above

Answers

Answer:

1. D

2. A

Step-by-step explanation:

To determine the type of line, find the slope.

Slopes which are the same are parallel
Slopes which are negative reciprocals are perpendicular
Slopes which are undefined (0 in the denominator) are horizontal.
Slopes which are 0 are vertical.

1. Find the difference in y values over the difference in x values. Calculate the slope using the formula:

$(y_2-y_1)/(x_2-x_1) = (6-2)/(4-6)=(4)/(-2)=-2$

$(y_2-y_1)/(x_2-x_1) = (1--1)/(1-5)=(2)/(-4)=(-1)/(2)$

These are reciprocals of each but not the negative or opposite signs of each other. This is none.

2. Find the difference in y values over the difference in x values. Calculate the slope using the formula:

$(y_2-y_1)/(x_2-x_1) = (6-0)/(4-7)=(6)/(-3)=-2$

$(y_2-y_1)/(x_2-x_1) = (3-1)/(5-1)=(2)/(4)=(1)/(2)$

These are reciprocals of each and the negative or opposite signs of each other. These are perpendicular.
