What is 70/6 times 18/4 in simplest form

Answers

70/6 × 18/4


70 * 18/6*4. cross out 18 and 6.

= 70*3/4

= 35 * 2 * 3/ 2*2

= 35*3/2

= 105/2

= 52.5 

OR

52 1/2.
70/6*18/4 = 105/2=52.5 52.5=\boxed{32 (1)/(2)} \n

The table below shows the outputs y for different inputs x:Input
(x) 1 1 3 3
Output
(y) 4 2 12 6


Part A: Does the table represent y as a function of x? Justify your answer. (5 points)

Part B: The total cost f(x), in dollars, for renting a paddleboat for x hours is shown below:

f(x) = 20 + 10x

What is the value of f(120), and what does f(120) represent? (5 points

Answers

Answer with explanation:

Part A:

  • A relation is said to be a function where each input has only a single output.

We usually take the input variable as 'x' and the output variable as 'y'.

In the given table, we can see that 1 is the input value corresponding to 4 and 2 both.

i.e.  one input value corresponds to two different output values that contradicts the definition of the function.

Thus  the given table doesn't represent any function.

Part B: Given : The total cost f(x), in dollars, for renting a paddle-boat for x hours is shown below:

f(x) = 20 + 10x

At x= 120 ,  f(120) = 20 + 10(120)=20+1200=1220

It represents that the total cost  for renting a paddle-boat for 120 hours is $1220.
Part A)
The table doesn't represent y as a function of x.
Why? One reason is that 1 or 3 is the first element in more than one ordered pair.
 Part B)
f(x) = 10x + 20
f(120)= 10*120 + 20 = 1200 + 20 = 1220 
f(120) represents cost of boating for 120 hours.

A ticket agency charges a 9.5% fee on all tickets sold. if a ticket costs $40, what is the fee?

Answers

to find a percent of money taken from the $40 than you have to multiply it by the percent you are trying to find 9.5%(.095)
40*.095=fee
40*.095=3.8
so the agency charges $3.80 for one $40 ticket
4.22 you just divide 40 by 9.5. I think...

Please someone help me and explain this question to me (the last question starting with a straw)

Answers


Each straw is  4-1/8 inches long.
You have one gigantic piece of straw material, 123-3/4 inches long.
How many straws can you cut it up to make ?

 ===>                    (123-3/4)  divided by  (4-1/8)            straws.

Each one costs  $0.015  to make.
So, once you find the number of short straws you have,
multiply

===>                 (the number of short straws) x ($0.015) .

That'll tell you how much it costs to make all of them. 


Now you know how to do it on your own.
If you don't get  30 straws  and  $0.45 , please try again.

write in slope intercept form an equation of the line that passes through the points (-4,2) and (6,-3)

Answers

Answer:

 y=-(1)/(2) x

Step-by-step explanation:

First, we would find the slope from(-4,2) to (6,-3). To find that it we would do (y_(1)-y_(2) )/(x_(1)-x_(2) ). It could also be the other way around depending on if you want to avoid negatives. (-3-2)/(6-(-4)) is (-5)/(10) or -(1)/(2). So, the equation so far is y=-(1)/(2) x+b. Then, we insert one of the y and x values in points (-4,2) or (6,-3) depending on what you're feeling. I chose (-4,2).

So, the equation now is 2=-(1)/(2)(-4)+b . Solving this, we get b=0. So the answer is y=-(1)/(2)x
