On a rectangular hyperbola, if one point is (2, 3) and y varies inversely to x, find y when x is 6.
Answer:
y = 1
Step-by-step explanation:
y is inversely proportion to x means that ,
y ∝ 1/x or ,
[tex]y\ \alpha\ \frac{1}{x}[/tex]
When we remove the proportionality sign we get,
[tex]y=k(\frac{1}{x})\\y=\frac{k}{x} \\[/tex]
now we know the point is (2 , 3) which means it corresponds to (x , y) which furthermore means y=3 when x=2,
so we insert these values and get the value of k.
[tex]y=\frac{k}{x} \\\\3=\frac{k}{2}\\\\6=k\\[/tex]
now the equation becomes,
[tex]y=\frac{6}{x}[/tex]
now we need to find y when x is 6 so just replace x with 6
[tex]y=\frac{6}{x}\\\\y=\frac{6}{6} \\\\y=1[/tex]
so we get the value of y is 1
this is harder so i put more points
Answer:
Sheet metal costs $20 per square foot.
Step-by-step explanation:
7.6x - 2.3x = 106
We are finding the value of x.
5.3x = 106
Divide both sides by 5.3.
x = 106 ÷ 5.3
x = 20
Answer and Explanation
__________________________________________________________
Sheet metal costs $20 per square foot( x = 20 )__________________________________________________________
Sheet metal costs 20 dollars per square foot, and we can figure this out by multiplying the 20 by the numbers and subtracting them.
__________________________________________________________
[tex]7.6x-2.3x=106[/tex] but what does x equal? ( 20 )
[tex]7.6\cdot20[/tex] = [tex]152[/tex]
[tex]2.3\cdot20[/tex] = [tex]46[/tex]
__________________________________________________________
[tex]152-46[/tex] = [tex]106[/tex]
Which is the same in the question, so x = 20.

Sydney has a bag of stuffed animals containing, 1 elephant, 4 bears, 3 cats, and 2 dogs. If she randomly selects 1 stuffed animal from the bag, places it on her bed and then selects another animal. What is the probability that she chooses a bear both times?
Answer:
2/15
Step-by-step explanation:
Step one:
given data
sample space
1 elephant,
4 bears,
3 cats, and
2 dogs.
sample size= 1+4+3+2= 10
Required:
By selecting without replacement, the probability that she chooses a bear both times
Step two:
the first event= Pr(bear)= 4/10= 2/5
the second event, the sample size is now 9 and the number of bears is now 3
Pr(bear)= 3/9= 1/3
Hence, the probability that she chooses a bear both times
= 2/5*1/3
=2/15

A Family purchased tickets to the movies in spent a total of $40.75. The family purchase five tickets there was a $.90 processing fee for each ticket. How much was 1 ticket.
Answer:
$7.25
Step-by-step explanation:
Total amount spent on the ticket = $40.75
Number of ticket purchased = 5
Processing fee per ticket = $0.90
Unknown:
Cost of each ticket = ?
Solution:
To solve this problem, we need to find the processing fee for the 5 tickets purchase;
Processing fee = number ticket x processing fee per ticket
Processing fee = 5 x 0.9 = $4.5
Now, the real cost a ticket = $40.75 - $4.5 = $36.25
So, cost per ticket is;
Cost = [tex]\frac{36.25}{5}[/tex] = $7.25

The Williams family goes shopping, and spend $95.00. They have a coupon for 20% off and the sales tax is 8%. What is the total cost of the shopping trip?
Answer:
The total cost of the shopping trip is:
$82.08
Step-by-step explanation:
The Williams family goes shopping, and spend $95.00. They have a coupon for 20% off and the sales tax is 8%. What is the total cost of the shopping trip?
Step 1
We find the price after the discount
The Williams family goes shopping, and spend $95.00. They have a coupon for 20% off
Hence:
20% × $95
= $19
Therefore: $95 - $19
= $76
Step 2
We find the amount of sales tax
The sales tax is 8%
Hence:
8% of $76
= $6.08
Our sales tax = $6.08
Step 3
The total cost of the shopping trip is calculated as:
$76 + sales tax
= $76 + $6.08
= $82.08
Whats the value of x? 3x - 5(x - 5) = -7 + 2x + 12
Answer:
x = 5
Step-by-step explanation:
Given
3x - 5(x - 5) = - 7 + 2x + 12 ← distribute and simplify left side
3x - 5x + 25 = 2x + 5
- 2x + 25 = 2x + 5 ( subtract 2x from both sides )
- 4x + 25 = 5 ( subtract 25 from both sides )
- 4x = - 20 ( divide both sides by - 4 )
x = 5
Savion is eating a pizza for lunch. He eats LaTeX: \frac{5}{8}\:5 8of it and gives the remaining pizza to his 2 coworkers. What fraction of the whole pizza will each of Savion's coworkers get if they share the remaining pizza equally?
Answer:
3/16x
Step-by-step explanation:
Let
Total pizza = x
Savion is eating a pizza for lunch. He eats 5/8 of it
Savion eats = 5/8 of x
= 5/8x
Pizza remaining = x - 5/8x
= 8x-5x/8
= 3/8x
gives the remaining pizza to his 2 coworkers. What fraction of the whole pizza will each of Savion's coworkers get if they share the remaining pizza equally?
= 3/8x ÷ 2
= 3/8x × 1/2
= 3/16x
Each of Savion's coworkers get 3/16x if they share the remaining pizza equally

Which expression in scientific notation is equivalent to (6×10^4)(3×10^5)
A 1.8×10^10
B 1.8×10^20
C 9×10^9
D 9×10^20
Answer: A) 1.8*10^10
Step-by-step explanation:
Multiply the constants together, and multiply the multiples of 10 together.
6*3 = 18
10^4 * 10^5 = 10^9
which gives you 18 * 10^9, but that isn't in scientific notation, because 18 isn't a number between 1 and 10
so you get 18 * 10 ^9
which is equal to 1.8*10^10

There are 20 children in a class 45% are girls, How many girls and boys are there?
Answer:
Step-by-step explanation:
each person represents 5%. so 45% are girls. 45/5 is 9, so 9 are girls. 20 minus 9 is 11 so 9 girls and 11 boys
