okay so let’s think about this. there’s a lot of extra information that we don’t need so let’s get rid of everything up to ”7 years”.
now.. she works 40 hours per week right? and she makes $2.13 per hour. so now that we have that, let’s think what 40 x $2.13 is. if you do the math right you should get 85.2 or $85.20. so that’s in one week, but then in a typical week sheserves 75 tables that have an average bill of $4q. so now that we have those numbers, we take 41 x 75 then add it to our weekly number. so we multiply the two together and we get 3075. not 30.75 but $3075.00! so take that and add it to 85.20.. you should get 3160.2, or $3160.20. but then typically an 18% tip, so let’s go back to the number before (41) and find what 18% of 41 is.
18% of 41 is 7.38 or in this case, $7.38. so once we have that, you’re gonna want to multiply 7.38 by 75 to get that total. if you do that you should get 553.5
okay.. now we have all the numbers we need. we’re already basically done, we just need to add the tips to the other total!
$3160.20 + $553.50 = $3713.70
so in a week, she makes $3713.70
i hope this helped you! good luck!

If triangle DEF is dilated by a scale factor of 1/2 with center of dilation at the origin
(0,0), what is the x-coordinate of E'?
Please help 20 points
Answer:
(4,2)
Step-by-step explanation:
I am not able to see your screen well but these are the points that I saw in the beginning for E. 8,4. Your x value is either left or right and your y value is up and down. I saw 8 units right and 4 u it's up. Now your scale factor is 1/2. Remember if the scale factor is less than one the figure reduces. Our rule for dilations is (x,y) → (kx,ky). The scale factor is represented by K. Since your scale factor is 1/2 we know our triangle will reduce. Let's plug 1/2 in our x and y valued.
So E is (8,4). 8*1/2 is 4 and 4* 1/2 is 2. Are new points are E' (4,2).

The sinusoidal function f(x)=33sin(7x−π12)+33 models the height, in centimeters, that a valve stem of the a tire is above ground x seconds after the tire begins to rotate.
How long does it take the valve stem to complete one revolution?
Answer:
0.90 seconds
Step-by-step explanation:
We will see that one complete revolution takes (2π/7) seconds.
How long does it take the valve stem to complete one revolution?Here we have the function:
f(x) = 33sin(7x−π/12) + 33
The time needed to do a full revolution is given by the period of the function.
Remember that:
sin(x) = sin(x + 2π).
Then:
sin(7x−π/12) = sin(7*(x + T) −π/12)
Then we must have:
2π = 7*T
Where T is the period.
Solving for T, we have:
2π/7 = T
This means that one complete revolution takes (2π/7) seconds.

what are the y-intercepts to graph the equation-4x - 3y = 36
Answer:
Y-Int = -12
Step-by-step explanation:
First, I would change the equation to slope intercept form:
-3y = 36 + 4x
3y = -36 - 4x
y = -12-4/3x
y = -4/3x - 12
-12 is the y-intercepts to graph the equation-4x - 3y = 36
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The given equation is -4x-3y=36
Now let us convert the given equation to slope intercept form y=mx+b
where m is the slope and b is the y intercept
Isolate the term y
-3y=36+4x
Divide both sides by 3
-y=36/3+4/3x
Multiply both sides by -
y=-12-4/3x
y=-4/3x-12
Slope is -4/3 and y intercept is -12
Hence, -12 is the y-intercepts to graph the equation-4x - 3y = 36

Choose the solution that is graphed on this number line.
A. x < 2
B. x > 2
C. x ≤ 2
D. x ≥ 2
c
Step-by-step explanation:
if you look at the graph, if there is a closed circle, that means x can be equal to whatever number the circle is on. if the circle is open, that means you don't include that number, which is in this case two. a closed circle means that x can be equal to 2. since the arrow is going from 2 to the left, x can be anything from two to any real numbers to the left. therefore, since to the left goes to numbers smaller than 2, x can either be equal to or less than two.
The solution of the inequality 3/4 x - 2/3 ≤ 5/6 which is graphed on given number line is x ≤ 2.
Here inequality is given as;
3/4 x - 2/3 ≤ 5/6
What is inequality?
A statement of an order relationship; less than, greater than, greater than or equal to, less than or equal to, between two algebraic expression is known as inequality.
Now,
3/4 x - 2/3 ≤ 5/6
3/4 x - 2/3 + 2/3 ≤ 5/6 + 2/3
3/4 x ≤ 7/3
Now multiply both side by 4/3;
[tex]\frac{3}{4} x *\frac{4}{3} \leq \frac{7}{3} *\frac{4}{3} \\x\leq \frac{28}{9} \\x\leq 3.11\\[/tex]
