The number of members going to the tournament is 9(optionC)
What are word problemsWord problem are mathematical problems written and words or sentence. To solve this type of problem we need to interpret the problem into mathematical equation.
Represent the number of members of the club by x and the cost per person be y. The total cost for the trip is $210
therefore 210/x = y equation 1
When 3 students join, the cost per person drops by $5.83
210/(x+3 )= y - 5.83
y = 210/(x+3 )+5.83
210/x = 210/(x+3) + 5.83
multiply all terms by x(x+3)
210(x+3) = 210x + 5.83(x²+9)
210x +630 = 210x + 5.83x²+52.47
630-52.47 = 5.83x²
577.53 = 5.83x²
x²= 577.53/5.83
x² = 99.06
x =✓99.06
x = ± 9.95
since 0.95 is not Up to a person and number of persons is a specific value, then the number of members going for the tournament is 9

What is the inverse of the function f(x) = 1/4x-12?
Answer:
[tex]\huge\boxed{f^{-1}(x)=4x+48}[/tex]
Step-by-step explanation:
In order to find the inverse of a function, we need to follow a couple of steps.
Step 1: Write the function as [tex]y=mx+b[/tex] Step 2: Swap all x and y values Step 3: Solve for y Step 4: Replace y with [tex]f^{-1}(x)[/tex]We can follow these steps to find the inverse of this function.
Step 1: We can just replace the f(x) with y, making our function [tex]y=\frac{1}{4}x-12[/tex].
Step 2: We can swap where the x and y values are, making our equation
[tex]x = \frac{1}{4}y-12[/tex]
Step 3: We can now solve for y.
[tex]x = \frac{1}{4}y-12[/tex] [tex]x + 12 = \frac{1}{4}x[/tex] [tex]4x+48 =y[/tex]We now have the function as [tex]y = 4x+48[/tex].
Step 4: We can now replace the y with [tex]f^{-1}(x)[/tex].
[tex]f^{-1}(x) =4x+48[/tex]
Therefore the inverse of [tex]f(x) = \frac{1}{4}x-12[/tex] is [tex]f^{-1}(x) =4x+48[/tex].

A JIT system uses kanban cards to authorize movement of incoming parts. In one portion of the system, a work center uses an average of 105 parts per hour while running. The manager has assigned an inefficiency factor of .35 to the center. Standard containers are designed to hold 3 dozen parts each. The cycle time for parts containers is about 90 minutes. How many containers are needed
Answer: 6 Containers are needed
Step-by-step explanation:
The ideal number of Kanban cards can be calculated using the following formula;
N = (DT × ( 1 + X)) / C
where N is total number of container,
D is panned usage rate of using work Centre
T is Average waiting time for replenishment of parts plus average production for a container of parts,
X is policy variable set by management that reflects possible inefficiency in the system ,
C is capacity of standard container.
Now, given that;
D = 105 parts
T = 90min = 90/60 = 1.5 hrs
X = 0.35
C = 3 × 12parts = 36 parts
so; we substitute
N = (105×1.5 × ( 1 + 0.35)) / 36
N = 212.626 / 36
N = 5.9063 ≈ 6
Therefore 6 Containers are needed

When this 3-digit number is rounded to the nearest hundred, it rounds to 400. The digit in the ones place is the fourth odd number you count beginning with 1. The sum of the digits is 12. What is the number?
Answer: 417
Step-by-step explanation:
Since the digit in the ones place is the fourth odd number that the person count beginning with 1, then the digit will be 7.
This means the number will be:
____ _____ 7. The number in the units and hundreds place are still unknown. But since the addition of the three numbers gives 12, and approximating to the nearest hundred gives 400. Then the number will be 417.
Check: 4 + 1 + 7 = 12
417 = 400 to nearest hundred

Estimate the sum by rounding each number to the nearest tenth: 0.214 +0.61
The estimate of the sum by rounding each number to the nearest tenth is 0.8
How to estimate the sum by rounding each number to the nearest tenth?Estimation is a method used for calculating the approximate value of a quantity (just to get a 'rough answer')
In estimation 1, 2,3, and 4 are rounded down while 5, 6, 7, 8 and 9 are rounded up.
Rounding each number to the nearest tenth:
0.214 = 0.2
0.61 = 0.6
The sum = 0.2 + 0.6 = 0.8

Answer:
bar graph??? we need a pic
The requried table that represents the bar graph is table H.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
The total number of students is 30,
Now,
10% of students take lunch,
So the number of students who take lunch,
= 10% of 30
= 3
Similarly,
Number of students who takes Breakfast = 9
Number of students who takes super = 18

What is the explicit formula for the geometric sequence with this recursive formula? { a1 = -7 an = an-1 • (1/3)
9514 1404 393
Answer:
an = -7(1/3)^(n-1)
Step-by-step explanation:
The explicit formula for a geometric sequence with first term a1 and common ratio r is ...
an = a1·r^(n-1)
The multiplier in the recursion relation is the common ratio: 1/3. The first term is given as a1 = -7. Putting these in the general formula, we have ...
an = -7·(1/3)^(n-1)

A garden has the form of a right triangle. One leg of the triangle is formed by a 2000-ft long sea wall. The hypotenuse of the triangle is 400 ft longer than the other leg. What are the dimensions of the garden?
Answer:
[tex]H = 5200[/tex] - Hypotenuse
[tex]S_1 = 2000[/tex] - Leg 1
[tex]S_2 = 4800[/tex] - Leg 2
Step-by-step explanation:
Represent the dimensions as:
[tex]H = Hypotenuse[/tex]
[tex]Other\ Legs = \{S_1,S_2\}[/tex]
So, we have:
[tex]S_1 = 2000[/tex]
[tex]H = 400 + S_2[/tex]
Required
Determine the dimensions
Apply Pythagoras theorem
[tex]H^2 = S_1^2 + S_2^2[/tex]
This gives:
[tex](400 + S_2)^2 = 2000^2 + S_2^2[/tex]
Open bracket
[tex]160000 + 800S_2 + S_2^2 = 4000000 + S_2^2[/tex]
[tex]160000 + 800S_2 = 4000000[/tex]
Collect Like Terms
[tex]800S_2 = 4000000 - 160000[/tex]
[tex]800S_2 = 3840000[/tex]
Solve for S2
[tex]S_2 = \frac{3840000}{800}[/tex]
[tex]S_2 = 4800[/tex]
Recall that:
[tex]H = 400 + S_2[/tex]
[tex]H = 400 + 4800[/tex]
[tex]H = 5200[/tex]
Hence, the dimensions are:
[tex]H = 5200[/tex]
[tex]S_1 = 2000[/tex]
[tex]S_2 = 4800[/tex]

Estimate the sum of 6107 and 2960 to the nearest thousand.
How u do this
Answer:
9,000
Step-by-step explanation:
You would add it together.
6107 + 2960 = 9,067
You round the thousand (9) to the 0.
The rule is that if any number next to the one your rounding is higher then 5 or is 5 then the rounding number will go up, if its 4 or below if won't go up but stay the same.
9,067 would not go up but stay the same because of the rule.
Estimations are guesses from the mind so an exact answer wouldn't work but its whatever.
