Answer: 60 degrees
Explanation: the angles of a triangle sum to 180 degrees, and all the angles in an equilateral triangle are the same so every angle in an equilateral triangle must equal 60 degrees.

Answer:
y = x -3
Step-by-step explanation:
From the graph we see the line goes from point (0, -3) to point ( 3, 0), so we can find the slope as m= rise ( go up 3) / run ( go to the right 3) = 3/ 3 = 1
From the graph we can also see the y-intercept ( where the line intersects the y axis is at b = -3
The general equation of the line is y= mx+ b
Our line's equation is y = x -3, because m=1 and b= -3

How to round off to the nearest degree
lets pick this number: 3,266.528
first let round to the nearest whole number by thousand
lets remove the .528 because we don’t need it
3,266
4000-3266 is 734
3,266 minus 3000 is 266
so rounded to the nearest thousand in the whole number is 3,000
or let’s say hundredths
3266.528
0.3- 0.28 is 0.3
0.28 - 0.2 is 0.8
so rounded to the nearest hundredth is 3,266.53
hope this helps :)
A.
Cars Amount
0 cars $-117.50
1 car $-113.50
2 cars $-109.50
3 cars $-106.50
4 cars $-102.50
10 cars $-77.50
50 cars $82.50
100 cars $282.50
I do not know what graph you have but, you can see how much money you will make because it will form a straight line on the graph. As long as you continue the line, you will be able to see how many cars you have to clean to make a certain amount of money. Same is for the table.
B.
The change in the amount of money earned with each car is $4.00
The change on the graph is shown by the increasing slope.
C.
The number of cars that need to be washed can be seen by using the formula y=4x-117.5
The information from part a and b is used to show that there is a constant change (slope) and that more money is made by washing more cars.
3. The members need to wash 30 cars (rounded up from 29.375) to break even.
4. The members would have to wash 249 cars (rounded from 248.125) to fund their Washington trip.
The members would have to wash 117 cars (116.875) to fund their Valentine's Day Dance.
5. They would have to wash 366 cars.
Realistic
This can be realistic if there are a lot of members in the Math Club and if they set up in a good location. It will be successful.
Not Realistic
This is not realistic because there are many other factors that need to be taken into consideration. There might not be enough cars or people that are willing to get their car cleaned by these students. There are other supplies that they might need to buy and more.
