The list below shows the results of a survey of favorite ice-cream flavors among middle-school students.
18 students voted for chocolate.
12 students voted for strawberry.
20 students voted for vanilla.
What percentage of the students chose vanilla as their favorite ice-cream flavor?
A. 20%
B. 30%
C. 40%
D. 50%
Answer:
C. 40%
Step-by-step explanation:
There are 18 + 12 + 20 = 50 students in total.
20 students voted for vanilla.
So... 20 out of 50 students voted for vanilla.
20/50 = 2/5
2/5 = 40%
Answer:
C. 40%
Step-by-step explanation:
First you add them together:
12+18+20 = 50
Then, you times both sides of the equation by 2
24+36+40 = 100
You can see that 20 changed to 40, and that's the answer!
Please help this is worth 15 points! Solve in y=mx+b from!
Answer:
The coordinates of every point on the line will solve the equation if you substitute them in the equation for x and y. The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept

Stuart wants to find the value of 3 3/4 -2 1/3 Before Stuart can subtract, he needs to rewrite both fractions with a common denominator. Drag a number or expression into each box to show how to write equivalent fractions so the new fractions have a common denominator.
Answer:
1 21/50
Step-by-step explanation:
3 3/4 = (3/4 x 4/4) = 3 9/12
2 1/3 = (1/3 x 3/3) = 2 4/12
3 9/12 - 2 4/12 = 1 21/50
Sean determines that the triangle shown in the diagram has angle measures of 40°, 40°, and 100°. Is Sean correct?
Answer:
Step-by-step explanation:
The two angles add to 80 degrees. Two remote angles always equal the exterior angle not connected to them.
That means that
x + 5 + x - 5 = 80
2x = 80
x = 40
The base angle is
40 + 40 + y = 180
80 + y = 180
y = 100
Note
You could do this much quicker by noticing that
80 + y = 189
y = 100
No he is not right
The given 2 angles are x + 5 which is 45 and x - 5 which is 35
All he got correct was the fact that the third angle is 100 degrees.
This year, Ann watched 80 movies. She thought that 52 of them were very good. Of the movies she watched, what percentage did she think were very good?
Answer:
65%
Hope this helps :)
Answer:
65%
Step-by-step explanation
The problem can be represented by a fraction; 52/80, then to solve for a decimal, we will just divide 52 / 80 = 0.65, which equals 65% because any decimal can be written as a percent.

Write an equation for each line (use the picture)
Red Line:
Blue Line:
Green Line:
Yellow Line:
Answer:
Red Line: y=4
Blue Line: y=-2
Green Line: x=-1
Yellow Line: x=6
Step-by-step explanation:
Red line: the line crosses through 4 on the y axis. Therefore, y=4.
Blue line: the line crosses through -2 on the y axis. Therefore, y=-2.
Green line: the line crosses through -1 on the x axis. Therefore, x=-1.
Yellow line: the line crosses through 6 on the x axis. Therefore, x=6.
This is a bit confusing because when you see a horizontal line your mind might assume it would be an x=. Yet, it is the opposite. Hope this helps!

6) Write a system of linear inequalities that is given by the following graph.
Answer:
The system of inequalities are x - y < 1 and y < - 2 The horizontal line shown in the graph has equation y = - 2 {As it is parallel to x-axis} Now, this line is dotted and the lower portion of the graph is shaded. So, the inequality will be y < - 2 ......... (1) Again, another line is there in the graph which passes through the points (1,0) and (0,-1)So, its equation will be
⇒ y + 1 = x ⇒ x - y = 1 Now, the origin (0,0) is within shaded zone of the inequality and putting x = 0 and y = 0, we get 0 - 0 < 1 So, the equation of the inequality is x - y < 1 {As the line is dotted} Therefore, the system of inequalities are x - y < 1 and y < - 2 (Answer)
