Suppose that you need to build as many chairs as possible. Each chair requires one seat, one back, and four legs. If you have 12 seats, 15 backs, and 44 legs, which of the chair components limits the number of chairs you can make?.
Answer:
legs limit the number of chairs that can be built
Step-by-step explanation:
The maximum number of chairs that can be built will be the minimum of the number of parts divided by the number of parts needed for each chair, as computed across the different kinds of parts required.
seats: 12 available, used 1 per chair: 12/1 = 12 chairs possible
backs: 15 available, used 1 per chair: 15/1 = 15 chairs possible
legs: 44 available, used 4 per chair: 44/4 = 11 chairs possible
The maximum number of chairs that can be built will be the minimum of 12, 15, and 11. That is, 11 chairs can be built, limited by the number of available legs.
Find the lateral area of the cone
Answer:
Lateral surface area of the cone is 1005 cm²Step-by-step explanation:
Given :-
Radius of cone = 16 cmHeight of cone = 12 cmTo Find :-
Lateral surface areaSolution :-
As we know that,
LSA of the cone = πrlFinding Slant height:

shawnye drinks 1/2 of 6-ounces glass of water in 2/3 hours how much water dose she drink in 1 hour.
Answer:
She drinks 4.5 oz in 1 hour.
Step-by-step explanation:
First,
1/2 of 6 would be 3
Shawnte drinks 3 ounces of water in 2/3 hrs.
3 oz = 2 / 3 hr
Multiply both sides by 3 to get 2 alone.
3*(3 oz) = 3*(2/3 hr)
9 oz = 2 hrs
She drinks 9 ounces of water in 2 hours.
9 / 2 oz = 2 / 2 hrs
Divide both sides by 2 so you can get how much she drinks in one hours
4.5 oz = 1 hr
An easier way of doing this is dividing both sides by (2/3)3 oz = 2/3 hrsDivide both sides by 2/34.5 oz = 1 hrsAnd boomHow do I solve problems like these
First of all we need to find the equations of the lines :
y( red ) = - x + 2
y(blue) = 2x - 1
Then we must to put the equations equal to each other and going to to find the value of x :
[tex]- x + 2 = 2x - 1[/tex]
Add both sides x
[tex] - x + x + 2 = 2x + x - 1[/tex]
[tex]2 = 3x - 1[/tex]
Add both sides 1
[tex]2 + 1 = 3x - 1 + 1[/tex]
[tex] 3 = 3x[/tex]
Switch sides
[tex]3x = 3[/tex]
Divide both sides by 3
[tex] \frac{3x}{3} = \frac{3}{3} \\ [/tex]
[tex]x = 1[/tex]
After u the value of x , put it in one the equations to find the value of y :
[tex]y = - x + 2[/tex]
[tex]y = - (1) + 2[/tex]
[tex]y = - 1 + 2[/tex]
[tex]y = 1[/tex]
Thus the solution is ( 1 , 1 ) .
What is the y-value of the solution to the system of equations? 3x 5y = 1 7x 4y = −13 −3 −1 2 5
The y-value of the solution to the system of equations is 2.
We have given a system of equation
3x + 5y = 1
7x + 4y = −13
What is the system of equation?A system of equations is a collection of two or more equations with the same set of unknowns.
First we have to find the value of x.
3x + 5y - 5y = 1 - 5y

Put the following equation of a line into slope-intercept form, simplifying all fractions.
3y−3x=15
__________________________________________________________
Hello! In this question, we will be changing our given equation to turn it into slope-intercept form.
__________________________________________________________
Explanation:
We are given the following equation:
3y − 3x = 15
Our goal is to turn the equation into slope-intercept form, which is:
y = mx + b
Let us rearrange the equation and simplify it:
3y − 3x = 15
Add 3x to both sides, which would cancel the 3x on the left.
3y = 3x + 15
Now, divide everything by 3 to get the "y" variable by itself.
y = x + 5
Therefore, your simplified equation in slope-intercept form would be:
y = x + 5
__________________________________________________________
Answer:
y = x + 5
__________________________________________________________
Part I: Reviewing the slope intercept form equation
Given equation:
3y - 3x = 15Slope intercept form: y = mx + b
[Where "m" is the slope and "b" is the y-intercept]
Part II: Isolating "y" and it's cooeficient on one side of the equation
In the slope intercept form equation, we can see that the "y" variable is completely isolated on one side of the equation. Therefore,
⇒ 3y - 3x = 15⇒ 3y - 3x + 3x = 15 + 3x⇒ 3y = 3x + 15Part III: Isolating "y" from it's cooeficient
The "y" variable in the slope intercept form has no cooeficient. Therefore, we need to isolate the cooeficient of "y" in our equation ( 3y = 3x + 15 ). This can be done by dividing 3 both sides or multiplying 1/3 both sides.
⇒ 3y/3 = (3x + 15)/3⇒ y = (3x + 15)/3Part IV: Simplify the other side of the equation
Finally, simplify the other side to obtain our equation in slope intercept form.
⇒ y = 3x/3 + 15/3⇒ y = x + 5Therefore, the equation in slope intercept form is y = x + 5.

Step-by-step explanation:
First, find out how many times the population will double. Divide the number of years by how long it takes for the population to double.
48÷24=2
The population will double 2 times.
Now figure out what the population will be after it doubles 2 times. Multiply the population by 2 a total of 2 times.
145,00022=580,000
That calculation could also be written with exponents:
145,000 x 2^2=580,000
After 48 years, the population will be 580,000 people.

Find the mean, median, and mode of the data with and without the outlier. 85, 77, 211, 88, 91, 84, 85
Answer:
With Outlier:
Median: 85
Mean: 103
Mode: 85
Without Outlier:
Median: 85
Mean: 85
Mode: 85
Step-by-step explanation:
Basically order the numbers from least to greatest. Include the outlier to find the median, mean, and mode. The median is clear as day with the outlier, being the middlemost number: 77, 84, 85, 85, 88, 91, 211. To find the mean, just add all of the numbers together and then divide them by how many numbers there are. In this case, that'd be 7 and you get 103. The mode is simple as it's the number that repeats the most, which is basically 85 since it repeats twice in the set. After you find the median, mean, and mode with the outlier, now rewrite the numbers (still least to greatest) but excluding the outlier (211). It should now be 77, 84, 85, 85, 88, 91. For the median, our middlemost numbers are 85 and 85, so simply just add them together and then divide by two. This gets you 85 for the median. For the mean, simply just add the numbers in the new set excluding the outlier and divide by 6 since that's how many numbers we have in the set now. This gives you 85. The mode is the number most repeated, and that's still 85.
