Use f(x)=3x/x+1 and g(x)=-2/x+1 to find the following
Answers
Answer:
a) 3x-2/x+1
b)14/5 as an improper fraction or 2 and 4/5 as a mixed number
Step-by-step explanation:
a) You just have to add f(x) and g(x) together and since the denominator is the same you can just add the numerators which gives you 3x-2/x+1
b)You have to plug in 4 to every x value in both functions so you get 3(4)/4+1 for f(x) and -2/4+1 for g(x) this simplifies down to 12/5 and -2/5 you then have to subtract those two fractions as stated in part b which gives you 14/5 as an improper fraction or 2 and 4/5 as a mixed number

If Gage gets 40 bucks a month how much months would it take him to get 300 bucks.
Answers
Answer:
7 to 8 months / most probably 8 months
7.5 months to be exact
Step-by-step explanation:
Hi there!! Let's work!
So lets Break it down,
Given: $40 every month
Prove: How many months till he has in total $300
----------------------------------------------------------------------------------------------
We need to multiply the number of months to 40 to get 300~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
So lets refer to a multiplication chart to make it easier:||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Here is an example of the equation we will use:400 x (months) = $300 / (or how much ever we get)
```````````````````````````````````````````````````````````````````````````````````````````````````````````````````````
As you can see:We have 2 final equations because we don't have a straight forward answer. (Refer to explanation below)
40 x 7 = 280
and
40 x 8 = 320
---------------------------------------------------------------------------------------------------------
So in problems like these we have to think like we would in real life, if you have an option you can write 7 to 8 months or you should write 8 instead of seven since they may be asking for a specific amount of months and after 8 months Gage will reach (surpass) his goal of $300 by $20.

Answers
Answer:
28.6918 or 28.69
Step-by-step explanation:
Answer:
$28.69
Step-by-step explanation:
First, let's find how much 18% of $34.99 is. We can do this in one step by multiplying 34.99 by .18.
[tex]34.99*.18=6.30[/tex]
Now, just subtract the sale from the original cost.
[tex]34.99-6.30=28.69[/tex]
Mina paid $28.69.

Suppose you play a coin toss game in which you win $1 if a head appears and lose $1 if a tail appears. In the first 100 coin tosses, heads comes up 42 times and tails comes up 58 times.
Answers
Answer:
Percentage of heads = 42 %
Net loss = $16
Step-by-step explanation:
Given:
Total number of tosses = 100
Number of heads come = 42
Number of tails come = 58
Find:
Percentage of heads
Net loss
Computation:
Percentage of heads = Number of heads come / Total number of tosses
Percentage of heads = 42 / 100
Percentage of heads = 42 %
Net loss = 58(1) - 42(1)
Net loss = $16
There are 20 pieces of bread to divide among 20 people. A man eats 3 pieces, woman eats 2 pieces and a child eats half piece of bread. Tell the correct combination of men, women and children so that they are 20 people in total and everyone gets the bread. Note that a man cannot eat less than 3 or more than 3. A woman cannot eat less than 2 or more than 2 and the child cannot eat less than half or more than half piece of the bread. You have to tell there are how may are men, women and children in those 20 people.
Answers
Answer:
14 children, 5 women, 1 man
Step-by-step explanation:
14 children which gives us 7 loves. 1 man which gives us 3 loves. 5 women which gives us 10 loves.
People: 14 + 1 + 5 = 20
Loves: 7 + 3 + 10 = 20
The number of men, women, and children among the 20 people would be as follows:
A). There are 5 women, 1 man, and 14 children.
Given that,
No. of bread pieces = 20
No. of people to be divided among = 20
We also know that,
1 man consumes = 3 pieces
1 woman consumes = 2 pieces
1 child consumes = 1/2 piece
Using the trial and error method, we can see that;
20 = (1 man × 3 pieces) + (5 women × 2 pieces each) + (14 × 1/2 piece each)
⇒ 20 = 3 + 10 + 7
∵ 20 = 20
Thus, option A is the correct answer.

The load that can be supported by a rectangular beam varies jointly as the width of the beam and the square of itsâ height, and inversely as the length of the beam. A beam feetâ long, with a width of inches and a height of inches can support a maximum load of pounds. If a similar board has a width of inches and a height of âinches, how long must it be to support âpounds?
Answers
The question is incomplete.Here is the complete question.
The load that can be supported by a rectangular beam varies jointly as the width of the beam and the square of its length, and inversely as the length of the beam. A beam 13 feet long, with a width of 6 inches and a height of 4 inches can support a maximum load of 800 pounds. If a similar board has a width of 8 inches and a height of 7 inches, how long must it be to support 1300 pounds?
Answer: It must be 392 inches or approximately 33 feet.
Step-by-step explanation: According to the question, the measures (width, length and height) of a beam and the weight it supports are in a relation of proportionality, i.e., if divided, the result is a constant.
For the first load:
width = 6in
height = 4in
length = 13ft or 156in
weight = 800lbs
Then, constant will be:
[tex]\frac{6.4^{2}}{156} k = 800[/tex]
[tex]k=\frac{800.156}{96}[/tex]
k = 1300
For the similar beam:
[tex]\frac{8.7^{2}}{L}1300=1300[/tex]
L = 49.8
L = 392in or 32.8ft
A similar board will support 1300lbs if it has 392 inches or 32.8 feet long.

Describe the error in determining whether the table represents a linear function.
Answers
Answers:
Describing the Error:
Choice B) The function is nonlinear and the increase in y is not constant.
Correcting the Error:
As x increases by a constant amount, y needs to increase or decrease by the same amount for the function to be linear.
=========================================================
Explanation:
Each time x goes up by 2, y is being multiplied by 4.
It may appear y is increasing at a constant rate, but this is not true. The jump from y = 4 to y = 16 is +12; while the jump from y = 16 to y = 64 is +48. The increase in y is not the same each time. This is just a rephrasing of what is discussed in the "correcting the error" section above.
So this is why the function is nonlinear. It turns out that this function is an exponential. Specifically, this is the function y = 2^x. For instance, if x = 8, then y = 2^x = 2^8 = 256. Graphing this function produces a curve that isn't a straight line, which is visual confirmation the function is nonlinear.

Solving for x:
since the sum of all 5 angles is 540°:

Compute 95% confidence intervals for the proportion of defective items in a process when it is found that a sample of size 100 yields 8 defectives.
Answers
Answer:
0.02683<x<0.133173
Step-by-step explanation:
The confidence interval formula is expressed as;
CI = p ± z√p(1-p)/n
p is the proportion
z is the confidence interval at 95% confidence
n is the sample size
Since it is found that a sample of size 100 yields 8 defectives, the sample proportion p = 8/100 = 0.08
Given
n = 100
z score = 1.96
p = 0.08
1-p = 1-0.08 = 0.92
Required
95% confidence interval
Substitute the given parameters into the formula as shown;
CI = p ± z√p(1-p)/n
CI = 0.08 ± 1.96√0.08(0.92)/100
CI = 0.08 ± 1.96√0.0736/100
CI = 0.08 ± 1.96(0.027129)
CI = 0.08 ± 0.053173
CI = (0.08-0.053173, 0.08+0.053173)
CI = (0.02683, 0.133173)
Hence the 95% confidence intervals for the proportion of defective items is 0.02683<x<0.133173
