Answer:
3/8 room
Step-by-step explanation:
Given data
We are told that 2 rolls of wire are needed to wire 1 room
Hence if 1 room needs 2 rolls
x rooms will need 3/4 rolls
cross multiply we have
2x= 3/4
Multiply both sides by 1/2
x= 3/4*1/2
x= 3/8 room

As input 20 relates to two different outputs 40 and 50 the relation is not a function.
What is a function?
A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
We know a relation is a function if it is one to one implies every input relates to different output or many one as different inputs lead to the same output.
The given information is represented by a diagram has one-to-many relations as the input 20 leads to the same output 50 so this is a one-to-many relation and not a function.

Answer: 4/3
Step-by-step explanation:
Slope is ratio of change in y with the change in x. From points C-->B, the change in y is 4. The change in x is 3. Therefore, the slope is 4/3
plssssss plsss help meeee ❤️❤️❤️
Answers
Answer:
slope is 2/3
Step-by-step explanation:
To solve for slope: y2-y1 / x2- x1.
Two points can be (0,50) and (30,70) since they intercept.
70-50 / 30- 0 = 20/30 = 2/3.
The slope is also going 20 units up and 30 units across which gives you 2/3.

Step-by-step explanation:
Beyonce is solving a system of equations: 2x – 3y = -2
4x + y = 24
She decides to use the elimination method to find the solution. She multiplies the second equation by 3 and adds it to the first equation to find 14x = 70, showing her that x = 5. Beyonce finds that y = 4.
Step 3: 4x + y = 24
4(5) + y = 24
20 + y = 24
-20 -20
y = 4
Step 1: 3(4x + y = 24) → 12x + 3y = 72
Step 2: 2x – 3y = -2
Solution: (5, 4)
+ 12x + 3y = 72
14x = 70
→ x = 5
Thinking about this process, Beyonce says out loud, “There are lots of ways I could go about solving this problem. I could do the method above or I could multiply the first equation by -2 and add the second.
Step 3: 4x + y = 24
4x + 4 = 24
-4 -4
4x = 20
x = 5
Step 1: -2(2x – 3y = -2) → -4x + 6y = 4
Solution: (5, 4)
Step 2: -4x + 6y = 4
+ 4x + y = 24
7y= 28
→ y = 4
“I seem to find that there is only one solution to the two equations, but I wonder if I will get the same solution if I use a different method?”
Explain how you know that a system od equations has an infinite numbe of solutions.
Answers
2x-3y = -2 --------> (1)
4x + y = 24 -------> (2)
multiply equation number (1) by -2
-4x + 6y = +4
remove the x value from both equation (1) and (2) because its the same number and different sign
6y + y = 4 + 24
7y = 28
divide both by 7
y = 4
now putting y=4 in two equations
2x - 3y = -2
2x-3(4) = -2
2x-12 = -2
2x = -2 + 12
2x = 10
x = 5
or
4x + y = 24
4x + 4 = 24
4x = 24-4
4x = 20
x = 5
so its (5,4)

a farmer has enough food to feed 50 animals in his cattle for 15 days . how long will the food last if there are 25 more animals in his cattle?
Answers
Answer:
The food will last for 10 days
Step-by-step explanation:
Proportions
The amount of food the farmer needs to feed his animals is proportional to the number of animals and to the number of days they are fed.
This can be written as:
Food=k*N*D
Where k is a constant, N is the number of animals and D is the number of days.
We know that the farmer has enough food to feed N=50 animals for D=15 days, thus:
Food=k*50*15=750k
If the same amount of food is used for 50+25=75 animals, then:
750k=k*75*D
Simplifying:
750=75*D
Dividing by 75:
D=10
The food will last for 10 days
5. There are three different colored M&Ms
red, green, and white. The probability of
selecting a red M&M is 2/5 and the probability
of selecting a green M&M is 1/4 so what is the
probability of selecting a white M&M?
Answers
The total number of red m&m out of all m&m is 2/5.
The total number of green m&m out of all m&m is 1/4.
if we add up 2/5 and 1/4, we can use that information to subtract from the total number of m&m to find the rest of m&m, which would be a total number of white m&m!
2/5 + 1/4 = ?
Common denominator. We will choose 20, since it is the lowest common multiple! (this means that 20/20 is the total number of all m&m, by the way. )
[tex]\frac{2(4)}{5(4)}[/tex] + [tex]\frac{1(5)}{4(5)}[/tex] = 8/20 + 5/20 = a
20/20 - a = ?
ANSWER: 7/20
The probability of selecting a white-colored M&M is 7/20.
The total number of red m&m out of all m&m is 2/5.
The total number of green m&m out of all m&m is 1/4.
if we add up 2/5 and 1/4, we can use that information to subtract from the total number of m&m to find the rest of m&m, which would be a total number of white m&m
2/5 + 1/4 = ?
Common denominator. We will choose 20, since it is the lowest common multiple (this means that 20/20 is the total number of all m&m, by the way. )
What is the probability?
Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
8/10 +5/20 = 8/20 + 5/20 = a
20/20 - a = ?
Therefore the probability of selecting a white M&M is 7/20.

A washer and dryer cost $711 combined the washer cost $61 more than the dryer what is the cost of the dryer
Answers
Answer:
$325
Step-by-step explanation:
Let the dryer be x and the washer be y
x+y= 711---------1
y= x+61-----------2
put y= x+61 in 1
x+x+61= 711
2x+61= 711
2x= 711-61
2x=650
x= 650/2
x=325
Hence the dryer cost $325
