Answer:
E. 55 hours.
Step by step:
Multiple $15x40, equals $600
Subtract $600 from $937.50, equals $337.50
50% more over 40 hours is $22.50
Divide $337.50 by $22.50, equals 15
Add 15 to 40, equals 45
So she worked 55 hours to get paid $937.50
Lindsey work for 55 hours to get paid of $937.50 before taxes.
Lindsey earns $15 per hour for the first 40 hours she works in a week.
50% more for every hour over 40.
In mathematics it deals with numbers of operations according to the statements.
Let lindsey work for x hours.
Now total earning of lindsey for 40 hours
= 15 *40
= $600
And Lindsey was paid $937.50
Lindsey paid for extra hours ,
= 937.50 - 600
= 337.50
Lindsey paid 337.50 for exta hours
extra hours that lindsey worked get 50% more than $15 per hour, $22.5 per extra hour
= 33.50/22.5
= 15 hours
Total hours that lindesy work is,
= 40 + 15
= 55 hours
Lindsey work for 55 hours to get paid of $937.50 before taxes.

Graph (C) represents y = x.
Graph (E) represents x = 3.
Graph (D) represents x + y = 3.
What is a graph?The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.
These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.
The graph of the function y = x is a straight line with equal values of x and y coordinates.
So, Graph (C) represents y = x.
The graph of x = 3 will be a straight line parallel to the y-axis at x equal to 3 so, Graph (E) represents x = 3.
The graph of x + y = 3 has y = 3, when x = 0 and x = 3 when y = 0, having coordinates (0, 3) and (3, 0) so, Graph (D) represents x + y = 3.

Graph the relation. Is the relation a function? Why or why not?
{(-1, 9), (0, -1), (-1, 4), (4, 9)}
No; a domain value has two range values.
Yes; there is only one domain value for each range value.
Yes; there is only one range value for each domain value.
No; a range value has two domain values.
Answer:
No; a domain value has two range values.
Step-by-step explanation:
Because domain value is the x value and range value is the y value. If the x value repeats then it is not a function.
Answer: I think the answer is letter A . "No; a domain value has two range values".
The Range is the difference between the lowest and highest values. Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. So the range is 9 − 3 = 6.... The range of the function is the set of all values that f takes.
Since
x = − 1
produces
y = 9
and
y = 4 , the relation
( − 1 , 9 ) , ( 0 , − 1 ) , ( − 1 , 4 ) , ( 4 , 9 )
is not a function.
The relation is not a function.

10 marbles what is the probability of drawing 2 blue marbles if the first marble is placed back in the bag before the second draw
Complete Question:
There are 10 marbles. What is the probability of drawing 2 blue marbles if the first marble is NOT placed back in the bag before the second draw.
2 yellow, 3 pink, 5 blue
Answer:
[tex]P(B_1\ and\ B_2) = \frac{2}{9}[/tex]
Step-by-step explanation:
Given
[tex]Blue = 5[/tex]
[tex]Pink = 3[/tex]
[tex]Yellow = 2[/tex]
[tex]Total = 10[/tex]
When the first blue marble is selected, the probability is:
[tex]P(B_1) = \frac{n(Blue)}{Total}[/tex]
[tex]P(B_1) = \frac{5}{10}[/tex]
Since the first marble is not returned, we have the following marbles left
[tex]Blue = 4[/tex]
[tex]Pink = 3[/tex]
[tex]Yellow = 2[/tex]
[tex]Total = 9[/tex]
The probability of picking a second blue marble is:
[tex]P(B_2) = \frac{n(Blue)}{Total}[/tex]
[tex]P(B_1) = \frac{4}{9}[/tex]
So, the required probability is:
[tex]P(B_1\ and\ B_2) = P(B_1) * P(B_2)[/tex]
[tex]P(B_1\ and\ B_2) = \frac{5}{10} * \frac{4}{9}[/tex]
[tex]P(B_1\ and\ B_2) = \frac{5*4}{10*9}[/tex]
[tex]P(B_1\ and\ B_2) = \frac{20}{90}[/tex]
[tex]P(B_1\ and\ B_2) = \frac{2}{9}[/tex]

Answer: Slope of line = [tex]\frac{1.2}{2}[/tex]
Graph- see picture.
Step-by-step explanation:
Graphs are graphed using y=mx+b
Slope (m) is written as [tex]\frac{rise}{run}[/tex], and y coordinate is up and down, x is left & right.
The y coordinate adds 1.2 every time, so the rise is 1.2.
The x coordinate adds 2 every time, so the run is 2.
The y intercept (b) simply means where the line intercepts the y axis.
It is given that the y intercept is 0.
So, the graphing equation: y= [tex]\frac{1.2}{2}[/tex]x
We don't need to put the y intercept because it is 0!
The graph is attached!

The difference of two positive numbers is 51. The quotient when one integer is divided by the other is 4. Find the two integers.
Answer:
x = -17
y = -68
Step-by-step explanation:
x - y = 51
y/x = 4 so we can say that y = 4x
using substitution:
x - 4x = 51
-3x = 51
x = -17
find 'y':
-17 - y = 51
-y = 68
y = -68
check:
-17 - (-68) = 51
51 = 51
-68/-17 = 4
4 = 4

Write the equation of the ellipse with the endpoints of the major axis (-11, 0) and (11, 0) and minor axis (0, -3) and (0, 3)
I don't particularly care about the answer, more judt the explanation of how I'm supposed to find it. thank you!!
Answer:
x/121 + y/9 = 1
Step-by-step explanation:
The major axis is 22 units long, in a horizontal line, and the center is in the middle of the major axis line segment. The center is at the origin. The distance of the whole axis is 22, and its endpoints are 11 units from the center. The axis length is 2a = 22, so a = 11.
Becasue the major axis is horizontal, this ellipse is wider than it is tall.
The minor axis is perpendicular to the major axis and it always shoter (hence the name 'minor'). In this case, it is vertical, is 6 units long, so we say that 6 = 2b, and b = 3.
The ellipse center is (h,k). But in this case, the center is the origin, so h = 0 and k = 0.
The equation for a horizontal ellipse is (x-h)²/a² + (y-k)²/b² = 1, a>b
(x-0)²/11² + (y-0)²/3² = 1
*** x/121 + y/9 = 1
The equation for a vertical ellipse is (x-h)²/b² + (y-k)²/a² = 1, a>b
If the bigger denominator is under 'x' term the ellipse is horizontal, with the longer axis being horizontal.
If the bigger denominator is under the 'y' term, the ellipse is vertical, with the longer axis being vertical.
I'm including 2 files.
The 'brainly ellipse' is form this particular problem.

Notice nothing was changed because of the property of exponents. An exponent to a power means to multiply them. A thing you should remember for all future cases is that the one-half power means square root. It is the exact same thing. Therefore the new expression I created is the square root of 'x' cubed.
A:) This would be equivalent to x^2/3
B:) This is equivalent to x^3/2 because the square root is the 1/2 power to the power of 3.
C:) This would be equivalent to x^2/3
D:) This is equivalent to x^3/2 because the square root is the 1/2 power, but multiplied by the power under the radical.
E:) If this answer is to the third power, then it is equivalent. I cannot tell from this picture.
I go to sleep at 8pm, wake up at 5.50am the next day, go back to sleep at 6.05am, and wake up for good at 7.01am. How long did I sleep for altogether?

The time between 8pm and 5.50am is 9 hrs and 50 minutes. The time between 6.05am and 7.01am is 56 minutes.
9 hrs and 50 minutes plus 56 minutes equals 10 hrs and 46 minutes

In the top row, the first and third polygons are regular polygons.In the bottom row, only the first polygon is a regular polygon============================================================
Explanation:
A regular polygon must have all sides of equal length. Also, all angles must be the same measure. This applies to the equilateral triangle in the upper left corner, and the square in the upper right corner. Each angle of the square is 90 degrees even though your teacher didn't use right angle markers.
The middle figure in the top row is not a regular polygon because the sides are not all the same length. Also, the angles are different.
--------------------
In the bottom row, only the first figure is a regular polygon for similar reasons mentioned earlier. The second figure is not a regular polygon because this figure is concave. Only convex polygons can be regular.
The third figure in the bottom row is not regular because one side is longer than the others.
