There are 2 red, 5 green, 3 blue, and 4 white points on a circle. Find the number of line segments which have vertices of different colors at the given points.
Answer:
Step-by-step explanation:
The number of those line segments which have endpoints of different colors is 47.
What is permutation and combination?
A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.
We have:
There are 5 red, 4 green, and 3 blue points on a circle.
There are different colored endpoints on each line segment that starts at a red point and travels to either a green point or a blue point.
There are 5 red points and 7 segments from each of them, making a total of 35 segments.
There are different colored endpoints on each line segment that leaves at a green point and travels to either a red or blue point.
There are 4 green points and 8 segments from each, for a total of 32 segments.
There are different colored endpoints on each line segment that leaves at a blue point and travels to either a green point or a red point.
Each blue point has 9 segments, and there are a total of 5 blue points.
Add all the ways = 35 + 32+ 27
= 94 segments.
Number of segment = 94/2 = 47
Thus, the number of those line segments which have endpoints of different colors is 47.

Tom solved the problem a different way. First he found the total area of the floor, and then he multiplied by the height. Does Tom’s method work? Explain.
What is the volume of the composite figure shown? Use 3.14 for π.
Answer:
25.12
Step-by-step explanation:
the formula of a cone is pi r^2 * h/3
r = radius and h = height
the radius is 2 and the height is 3
and the question says use 3.14 instead of pi so
we have
3.14 * 2^2 * 6/3
2*2 or 2^2 = 4
3.14 * 4 * 6/3
6/3 = 2
3.14 * 4 * 2
4*2 = 8
and 8 * 3.14 is 25.12
The figure shows a line graph and two shaded triangles that are similar:

Two friends, Rahul and Arun, took summer jobs. The equation y = 17.3x represents Arun's earnings in dollars and cents, y, for working x hours. The graph below represents Rahul's earnings in dollars and cents, y, for working x hours.
How much more does Rahul earn per hour than Arun?
Answer: Rahul earns 3.5 dollars more per hour than Arun.
Step-by-step explanation:
17.3 is the slope of Arun's earnings. To find what Rahul makes in an hour, you can find the slope of his graph below.
Use the two points, (10,208) and (20, 416)
Use the formula for calculating slope:
416-208=208
20-10=10
---------------------
208/10= 20.8
Rahul's equation can be set up like this:
y=20.8x
Subtract:
20.8-17.3=3.5
Therefore, Rahul earns 3.50 dollars more per hour than Arun.

Graph m(x) on a coordinate plane to determine whether or not the function represents a direct variation. In complete sentences, describe your conclusion and reasoning. Include your graph in your answer.
Answer:
m(x) = 1.5x . . . . direct variation
Step-by-step explanation:
You want to know if the function m(x) represents direct variation, given a table of values.
Direct variationAn equation for direct variation is ...
y = kx
where k is a constant that can be found as the ratio of any (x, y) pair:
k = y/x
k = -1.5/-1 = 1.5/1 = 3/2 = 6/4 = 1.5
The ratios are constant, hence m(x) is direct variation with a constant of variation of 1.5.
GraphThe graph of direct variation is a straight line through the origin. The given points lie on such a line.

What is the decimal expansion for 12
2
3?
A.12.6
B.12.65
C.12.6
D.12.66
pls help me
Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.
Answer:
I believe the answer is D.

Scientists are preparing two satellites to be launched. The satellite, Space Explorer B, flies 79200 miles in 18 hours. The graph below represents the number of miles,
Answer:
4400
Step-by-step explanation:
I think this is right sorry if its not. Have a good night, sorry if im late.
Answer:
4600 miles
Step-by-step explanation:
You want to know the difference in miles per hour between a satellite traveling 45000 miles in 5 hours and one traveling 79200 miles in 18 hours.
Miles per hourThe speed in miles per hour is the ratio of miles to corresponding hours. The difference in miles traveled in one hour will be ...
A speed - B speed
45000 mi/(5 h) - 79200 mi/(18 h) = 4600 mi/h
Explorer B travels 4600 fewer miles in an hour than Explorer A.

Pet supplies makes a profit of $5.50 per bag on it’s line of natural dog food. If the store wants to make a profit of NO LESS THAN $5225, how many bags of dog food does it need to sell???
10 pts for a clear explanation
Answer:
the pet store needs to sell 950 or more bags of dog food.
Step-by-step explanation:
Let’s define our variable: x= number of bags of dog food.
Since we need to make more than or 5225 dollars, we need to make an inequality to show this.
\(5.50x\geq 5225\)
Let’s solve the inequality.
\(5.50x/5.50 \geq 5225/5.50\)
\(x\geq 950\)
So, the pet store needs to sell 950 or more bags of dog food.

21 point 7 2, inches
27.72
inches
27 point 7 2, inches
Answer:
3.62 inches
Step-by-step explanation:
Given :
Ed's string length = 21.72 inches
Georgiana's string length = 1/6 of Ed's string length
To Find :
Georgiana's string length
Solving :
Georgiana's string length = 1/6 of Ed's string length
Georgiana's string length = 1/6 × 21.72
Georgiana's string length = 21.72/6
Georgiana's string length = 3.62 inches
Answer:
3.62 inches
Step-by-step explanation:
Step-by-step explanation:
Given that Ed's string length is = 21.72 inches
And that Georgiana's string length is = 1/6 of Ed's string length
We need to find Georgiana's string length
Georgiana's string length = 1/6 of Ed's string length
And Georgiana's string length = 1/6 × 21.72
Georgiana's string length = 21.72/6
Which would bring us that Georgiana's string length is = 3.62 inches

A bag has 8 red marbles, 4 green marbles, and 2 yellow marbles. Bill draws a red marble from the bag and does not replace it. What is the probability of Bill drawing a yellow marble next? A. 1/7 B. 1/13 C. 2/13 D. 1/14
Answer:
c. 2/13
Step-by-step explanation:
The bag starts with 8 red marbles, 4 green marbles, and 2 yellow marbles. Since he draws a red marble from the bag and does not replace it, there will be one less marble.
So now there are 7 red marbles, 4 green marbles, and 2 yellow marbles. Add the number of marbles together and then find the probability of drawing a yellow marble.
7+4+2 = 13
2/13
So the probability of Bill drawing a yellow marble would be 2/13.
here are some numbers 2 9 14 36 40 what number is a multiple of 12 which number is a prime number which number is a factor of 64
Answer: 36 is a multiple of 12
2 is a prime number.
2 is a factor of 64
Step-by-step explanation:
12 × 3 =36, so 12 is one of the factors.
2 is the only even prime number. All other even numbers are multiples of 2.
9 is not a prime number. 3 × 3 = 9
2 is a factor of 64. 2 × 32 = 64 None of the other numbers given can divide evenly into 64, so they are not factors of 64.
Answer:36 is a multiple of 12
Step-by-step explanation:
