Answer:
4/5
Step-by-step explanation:
SImply use slope formula. We see the graph has defined points at (5, 4), and (-5, -4).
m=(Y2-Y1)/(X2-X1)
(4-(-4))/(5-(-5))=8/10
Simplify 8/10
=4/5
Answer:
terms: 3 terms, 4e,7e, and 5
like terms: 4e and 7e
coefficients:4e and 7e
constants:5
Step-by-step explanation:
terms are the numbers and or variables being added
like terms consist of the same variables
coefficients are the numbers being multiplied by a variable
constants are any numbers that aren't being multiplied by a variable
Let's make p stand for popcorn and d for drinks. Using those variables, we can create our equations:
2p + 3d = 18.25
4p + 2d = 27.50
From this, we can use substitution or elimination to solve:
For substitution, in the second equations, we could factor out a 2, divide both sides by 2, and then move the left over 2p to the other side to isolate d to put into the first equation.
For elimination, we can multiply the first equation by -2 so that we can remove the 4p and focus on solving for d.
I'll be using elimination in this case:
-2(2p + 3d = 18.25) --> -4p - 6d = -36.50
-4p - 6d = -36.50
4p + 2d = 27.50
-4d = -9.00
d = 2.25
4p + 2 * 2.25 = 27.50
4p + 4.50 = 27.50
4p = 23.00
p = 5.75
Now let's check our answer:
2 * 5.75 + 3 * 2.25 = 18.25
11.50 + 6.75 = 18.25
18.25 = 18.25
So drinks cost $2.25 and popcorn $5.75
Circle graphs are used to display the relationship between variables using a complete circle
The angle measures of the sections are 180 degrees, 72 degrees, 72 degrees and 36 degrees, respectively.
The count of the animals are given as:
- Squirrel = 25
- Rabbit = 10
- Deer = 10
- Raccoon = 5
The total count of animals is:
The angle measure of each section is then calculated using:
So, we have:
Simplify the numerator
Divide
