On average, Ethan drinks 3/4 of an 10 ounce glass of water in 2 minutes how many glasses of water does he drink in one hour
Answer:
22.5 glasses of water
Step-by-step explanation:
Because 3/4 of 10 is 7.5 and if he drinks that every 2 min you have to multiple 7.5 by 30 because 60/2 is 30 which is the amount of min in an hour. when you multiple, you get 225. you have to divide that many oz by 10 because that is how many oz are in a glass and you get 22.5 glasses.
-8 + k = -17
What is k to make this equation true
Answer: The answer is k= -9
Step-by-step explanation:
this is how you solve it :
-8+k=-17
so then you add 8 to both sides so it would look like
-8+k+8=-17+8
then you simplify
after you simplify it would equal k=-9

Answer:
$1.80, $2.90, $4.00, $10.90
Step-by-step explanation:
For 9/10 mile, the price will be $1.80. For 2 miles, the price will be $2.90. For 3 1/10 miles, the price will be $4.00, and for 10 miles, the price will be $10.90. The relationship between distance travelled and the price is not proportional because it costs $1.00 for the first 1/10 mile and then for every additional 1/10 mile, it only costs $0.10. Hope it helps!
The given table of values represents a linear equation. What is the slope?
A. 4
B. 5
C. 3
D. 6
Answer:
C. 3
Step-by-step explanation:
Formula for slope is given as [tex] m = {y_2 - y_1}{x_2 - x_1} [/tex]
The coordinates of any two points can be used in this formula. Let's use, (1, 5) and (2, 8).
Let,
[tex] (1, 5) = (x_1, y_1) [/tex]
[tex] (2, 8) = (x_2, y_2) [/tex]
Plug the values into the formula:
[tex] m = {8 - 5}{2 - 1} [/tex]
[tex] m = {3}{1} [/tex]
[tex] m = 3 [/tex]

3x-2y=-7
2x+5y+=8
Answer: 3x-2y=-7= Slope = 3.000/2.000 = 1.500
x-intercept = -7/3 = -2.33333
y-intercept = 7/2 = 3.50000

Candace is visiting a local water park. The table shows information about the number of hours ( input values) and the total cost (output values)
Can anyone help??
(it’s a timed quiz)
Answer:
B. Domain: {1, 3.5, 5, 7.5, 9}
F. Range: {2, 6.50, 7.00, 9.00, 12.50}
Step-by-step explanation:
The set of input values make up the domain of the function, while the corresponding set of output values is the range of the function.
That is, the domain is the number of hours, while total cost is the total cost.
Domain would be: {1, 3.5, 5, 7.5, 9}
Range would be: {2, 6.50, 7.00, 9.00, 12.50}
The packages of wrapping paper cost $2.75 per package. At the last moment, Sally notices gift bags that cost $4. 99. Is it cheaper to wrap the CD or put it in a gift bag? Explain your answer.
Answer:

Which line is perpendicular to 3y+2x=12?
y=-2x+6
2x+3y=6
y+3x=-2
6x-4y=24
Step-by-step explanation:
Given line equation : 3y+2x=12
3y=−2x+12
y=(−2x+12)/3
y=-2x/3+4
m=-2/3
perpendicular -1/m=3/2
y=mx+c
y=3/2x+12
2y=3x+12
Graph the line with the slope of 3/5 and goes through the point (1,2)
Answer:
Here's a screenshot of the correct line:
The line with the slope of 3/5 and goes through the point (1,2) is y = 3/5x + 7/5
The equation of a straight line is given by:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
Given the line has a slope of 3/5 and goes through the point (1,2). The equation of the line is given by:
[tex]y-y_1=m(x-x_1)\\\\y-2=\frac{3}{5}(x-1)\\\\y-2=\frac{3}{5}x-\frac{3}{5} \\\\y=\frac{3}{5}x+\frac{7}{5}[/tex]

Suppose you have $75 in your savings account and you save an additional $5 each week. Your friend has $30 in his savings account and saves an additional $10
per week. In how many weeks will you have the same amount of money?
Answer:
9 weeks
Step-by-step explanation:
5x+75=10x+30
-5x -5x
75=5x+30
-30 -30
45=5x
÷5 ÷5
9=x
x=9
it will take 9 weeks for you and your friend to have the same amount of money in your savings accounts.
To determine the number of weeks it takes for both you and your friend to have the same amount of money in your savings accounts, we need to set up an equation.
Let's denote the number of weeks as 'x'. For you, the amount of money in your savings account after 'x' weeks can be calculated as follows:
Amount of money in your account = $75 + $5x
For your friend, the amount of money in his savings account after 'x' weeks can be calculated as:
Amount of money in your friend's account = $30 + $10x
To find the number of weeks where you both have the same amount of money, we set up the equation:
$75 + $5x = $30 + $10x
Simplifying the equation:
$5x - $10x = $30 - $75
-$5x = -$45
Dividing both sides of the equation by -5 gives us:
x = 9
Therefore, it will take 9 weeks for you and your friend to have the same amount of money in your savings accounts.

A.
It is the graph of f(x) reflected about the x-axis and shrunk vertically by a factor of 8.
B.
It is the graph of f(x) reflected about the x-axis and stretched vertically by a factor of 8.
C.

D.
It is the graph of f(x) reflected about the y-axis and stretched horizontally by a factor of 8.
Answer:
OTHER GUY IS WRONG!!!
Given that,
Each statement describes a transformation of the graph of f(x) = x.
We have to determine,
Which statement correctly describes the graph of g(x) if g(x) = -8f(x)?
According to the question,
Let, The graph f(x) = x,
Where r is the real number which is r >0.
And The graph of g(x) if g(x) = -8f(x),
The value of the r is -8.
The graph which describes the transformation of the given graph in the steps follows all the steps given below.
The function g(x) = 8f(x) reflects stretched the graph of f(x) vertically by a factor of r.The function g(x) = -8f(x) reflects the graph of f(x) about the x-axis and stretched the graph of f(x) vertically by a factor of r.The graph of g(x) = f(8x) shrink the graph of f(x) horizontally by a factor of r.The function g(x) = f(-8x) shrink the graph of f(x) about the y-axis and shrink the graph of f(x) horizontally by a factor of r.Hence, The graph of f(x) reflected about the x-axis and stretched vertically by a factor of 8.
