Answer:
Rs 2
Step-by-step explanation:
12 pencils = Rs 16
50% profit on Rs 16 = 50/100 × 16 = 8
selling price = 16 + 8 = 24
cost of 1 pencil = 24/12 = Rs 2

For each function, what is the output of the given input? For f ( x ) = 4 x + 7 , find f ( 4 ) . 1
Answer:
let's see what to do buddy...
Step-by-step explanation:
To find the output of a number in a function, we must put it in the equation of the function instead of the x .
So to find output of ( x = 4 ) , we must put 4 instead of x in the equation .
Let's do it :
[tex]f(4) = 4 \times (4) + 7 \\ \\ f(4) = 16 + 7 = 23 \\ [/tex]
So the output number of ( x = 4 ) is 23 .

And we're done.
Thanks for watching buddy good luck.

As the music plays,the volume changes In the beginning of the piece can be modeled by the equation s=10Ix-4I+50 where s represents the sound level in decibels and x represents the number of measures of music played. explain in words each step to find the following equation at what number(s) measures played would the sound level be at 80
Answer:
-127
Step-by-step explanation:
s = 101x-41+50
80 = 101x - 4+ 50
-101x
-181 = x - 4 +50
-181 = x -54
+ 54
-127 = x

using the fact that the black triangle represents the mean and/or the understanding of what a deviation is, explain why this balancing beam would stay balanced went to Blue circles are removed. Be thorough with your explanation and use Multiple sources of evidence
Answer: the left side is balanced with the right side
Step-by-step explanation:
Left side:
1 barrel (located at 2) is 1 unit from the fulcrum (triangle) → 1(1) = 1
2 barrels (located at 1) are 2 units from the fulcrum (triangle) → 2(2) = 4
1 barrel (located at 0) is 3 units from the fulcrum (triangle) → 1(3) = 3
Total = 8
Right side:
1 barrel (located at 6) is 3 units from the fulcrum (triangle) → 1(3) = 3
1 barrel (located at 8) is 5 units from the fulcrum (triangle) → 1(5) = 5
Total = 8
The distribution of the weight on the left side equals the distribution of weight on the right side so the beam is balanced.

The manager of a local fast-food restaurant is interested in improving the service provided to customers who use the restaurant's drive-up window. As a first step in this process, the manager asks an assistant to record the time (in seconds) it takes to serve a large number of customers at the final window in the facility's drive-up system. The file P08 07 xlsx contains a random sample of 200 service times during the busiest hour of the day
a. Identify the relevant population.
b. Calculate and interpret a 95% confidence interval for the mean service time of all customers arriving during the busiest hour of the day at this fast-food operation.
c. If the manager wants to improve service, at least during the busiest time of day, does this contidence interval provide useful inlormation? What useful information does it not provide?

A line has a slope of - 1/4 and passes through point(-5/4,1)
What is the equation of the line?
Answer:
y= -1/4x - 1/4
Step-by-step explanation:
y - y1 = m(x - x1)
y - 1 = -1/4 (x -(-5/4))
y - 1 = -1/4x - 5/4
y = -1/4x - 1/4

If you multiply a number by four and then subtract negative ten, the difference is negative twenty-two. What is the number?
Answer:
n=-3
Step-by-step explanation:
To solve start with the 4n-10=-22
+10 to both sides and you get 4n=-12
Divide each side by 4 and you get n=-3
To check plug -3 in for n and you'll get the -2 once you solve it.

F is between EG. If EF = 2x-12, FG = 3X-15 and EG = 23. find the values of x, EF, and FG.
Answer:
The answer is A
Step-by-step explanation:
The first thing to do is see which two lengths of EF and FG equals EG which is 23. If you add together B's options you get -12 and if you add C's options, you get 77. So that leaves us with the options of A and D. From there, just plug in each value of x and see which one gets you the right values. Hope this helps
If the sales tax in Texas is 8.25%, what is the
total cost of a new backpack for $36?
Answer:
[tex]Total\ Cost = \$38.97[/tex]
Step-by-step explanation:
Given
[tex]Backpack = \$36[/tex]
[tex]Sales\ Tax = 8.25\%[/tex]
Required
Determine the Total Cost
Total cost is calculated as thus
[tex]Total\ Cost = Backpack + Backpack * Sales\ Tax[/tex]
[tex]Total\ Cost = \$36 + \$36 * 8.25\%[/tex]
[tex]Total\ Cost = \$36 + \$2.97[/tex]
[tex]Total\ Cost = \$38.97[/tex]

Answer:
Step-by-step explanation:
1) Composite functions are function of two or more functions to serve as one function. For example, given d(x) and g(x), we can write both as composite function as d(g(x)). We can call it function of a function. Hence, from the following function, the following options except option B are composite.
d(x)g(x) is the product of the two functions not a composite.
Option B is correct.
b) Given h(x) = x-1 and d(x) = 7x+3
H(3) = 3-1
H(3) = 2
d(2) = 7(2)+3
d(2) = 14+3
d(2) = 17
h(3)+d(2) = 2+17
h(3)+d(2) = 19 (option D)
c) Given t(x) = -x² + 7x + 1 and r(x) = 5x² - 2x + 8, we are to first find the function
t(x)-r(x)
t(x)-r(x) = -x²+7x+1-5x²+2x-8
t(x)-r(x) = -x²-5x²+7x+2x+1-8
t(x)-r(x) = -6x²+9x-7
Substitute x as 2
(t-r)(2) = -6(2)²+9(2)-7
t-r (2) = -6(4)+18-7
(t-r)(2) = -24+11
(t-r)(2) = -13 (option C)
d) If h(x) = 4x + 2 and g(x) = 3x - 1,
h-g = 4x+2-(3x-1)
h-g = 4x+2-3x+1
h-g = 4x-3x+2+1
h-g = x+3
h-g(4) = 4+3
(h-g)(4) = 7
e) If g(x) = x - 4 and h(x) = x + 5, we are to find f(x)h(x)
h(x)g(x) = (x-4)(x+5)
h(x)g(x) = x(x)+5x-4x-20
h(x)g(x) = x²+x-20
Hence the product of h(x) and g(x) is x²+x-20. Option D is correct

There are 15 students in my first period class. If 6 of the students in the class are boys, what percent of the students are boys?
A. 60%
B. 25%
C. 40%
D. 30%
Answer:
C
Step-by-step explanation:
If you were to multiply 15 by 40% it would equal 6.
No. of students in 1st class= 15
No. of boys = 6
Percentage of boys = 6/15 ×100
= 2/3×100
= 40%
