Send him a polite email explaining that, while you completed the assignment on your own (which I am assuming to be true), by stumbling upon the solutions in advance you had a hard time doing anything different. Professors are people--he should recognize his mistake and appreciate that you were forthcoming. Chances are he'll reassign the project or discount its weight toward your grade and just tell people to review it anyway because you need to know the material. The sooner you say something the better though. Indeed, after a while it may look like you were trying to hide it from him.

Step-by-step explanation: area of triangle one = 6; area of triangle two = 6; area of 6 by 4 rectangle = 24; area of 5 by 6 rectangle = 30; area of 6 by 3 rectangle = 18
6+6+24+30+18 = 84
10 points pls make an explination.....
Answer:
26
Step-by-step explanation:
Assume that the total time spent in the morning which includes getting dressed, eating breakfast, making her bed, and driving to work is x.
Time getting dressed = ¹/₃x
Eating breakfast = 10 mins
Making bed = 5 mins
¹/₃x + 10 + 5 = 35 ½
¹/₃x + 15 = 35 ½
¹/₃x = 35 ½ - 15
¹/₃x = 20 ½
x = 20 ½ / ¹/₃
= 61.5 minutes
Total morning routine is is 61.5 mins
Time taken to drive to work is;
= 61.5 - 35 ½
= 26 minutes

write the equation of the line in point-slope slope-intercept and standard forms where the two points is (5,-6) and (6,-5). 20 points and brainliest to the best answer
Answer:
Slope-intercept form: y = x - 11
Standard form: y - x = 11
Point-slope form: y + 5 = (x - 6)
Step-by-step explanation:
Given the two points, (5, -6) and (6, -5):
We must first solve for the slope, as it will be used in the point-slope and slope-intercept forms.
SlopeLet (x₁, y₁) = (5, -6)
(x₂, y₂) = (6, -5)
Substitute these values into the following slope formula:
[tex]\LARGE\mathsf{m = \frac {(y_2\: -\: y_1)}{(x_2\: -\: x_1)}}[/tex]
[tex]\LARGE\mathsf{m = \frac {-5\: -\: (-6)}{6\:-\:5}\:=\frac{-5\:+\:6}{ 1 } \:=\frac{1}{ 1 }}[/tex]
m = 1
Therefore, the slope of the line is 1.
Y-interceptNext, we must determine the y-intercept of the line. The y-intercept is the point on the graph where it crosses the y-axis, at point (0, b). In order to find the y-intercept, use one of the given points, (6, -5), and the slope, m = 1, and substitute into the slope-intercept form, y = mx + b:
y = mx + b
-5 = 1 (6) + b
-5 = 6 + b
Subtract 6 from both sides:
-5 - 6 = 6 - 6 + b
-11 = b
Therefore, the y-intercept is (0, -11), where b = -11.
Now that we have the value for the slope of the line, m = 1, and the y-intercept, b = -11, we could proceed in creating the linear equation in slope-intercept, point-slope, and standard forms.
Given our slope, m = 1, and the y-intercept, b = -11, we can express the linear equation in the following forms:
Slope-intercept form: y = x - 11Standard Form:We could transform the slope-intercept form into the standard form:
Ax + By = C
where:
A, B, and C are integersA and B ≠ 0A is a non-negative integer.Transform the slope-intercept form into standard form.
Start by subtracting x from both sides of the equation:
y - x = x - x - 11
y - x = -11 ⇒ This is the standard form where A = 1, B = -1, and C = -11.
Point-slope form:Use one of the given points, (6, -5) and substitute into the point-slope form:
y - y₁ = m(x - x₁)
y - (-5) = 1(x - 6)
y + 5 = (x - 6) ⇒ This is the point-slope form.

If you change the sign of a point’s x-coordinate, how will the location of the point change?
A. The point will move down and to the left. B. The point will cross over the x-axis
C. The point will cross over the y-axis D. Not enough information provided
Answer:
B
Step-by-step explanation: x you move the x axis....
Answer:
C.
Step-by-step explanation:
The X-axis labels points horizontally. A change in a points sign on the X-axis will move the point to it inverse on the X-axis. When change the sign on the x-axis the point will end up on the opposite side of the y-axis.

why is the sum of odd numbers always a perfect square
Answer:
ONLY perfect squares will have odd number of total factors and ALL perfect squares will have an odd number of total factors. Referring back to the formula of total factors, since each of the powers is even, so each of (power + 1) is odd; their product will definitely always be odd.

2,075 ÷ 2 =
R
Answer:
R=1037.5
Step-by-step explanation:
2075/2=
2 goes into 2075 how many times?
1 | 0 | 3 | 7 | .5
2 goes into 2 1 time= 1
2 goes into 0 0 times = 0
2 goes into 7 3 times = 3
we have 1 left over from the 7 (3*2=6 --- 1 less than 7)
carry the 1 to the 5 to make 15
2 goes into 15 7 times = 7
we have the 1 left from the 15 (7*2=14 --- 1 less than 15)
put the 1 over 2 to get 1/2 (aka 0.5) = .5
altogether, you have 1037.5

What is the greatest common factor of 5 and 15?
Answer:
5
Step-by-step explanation:
In order to find the GCF (Greatest Common Factor) of two numbers, list each number's factors. The number of greatest value that shows in both sets is the GCF.
First, list the factors of 5 and 15.
5 - 1, 5
15 - 1, 3, 5, 15
The numbers that show in both sets are 1 and 5. Since 5 is the greatest of the duplicate numbers, 5 is the GCF.
Which of the following reasons helps explain why − 7/0 is not a rational number.

Hi!
The number has a zero in the denominator.
If a number has a 0 in it's denominator, then it's not rational

Ben and Jane are both bringing cupcakes to school. Ben brings 25 cupcakes, and Jane brings 6 times as many cupcakes as Ben. Jane put an equal number of cupcakes on each of the 8 tables in her classroom out of the cupcakes she has brought. How many cupcakes could Jane put on each table out of the cupcakes she brought if each table will have the same number of cupcakes?
Answer:
Step-by-step explanation:
25 x 6 = 150. Then you do 150 divided by 8 = 18.75. (You have a remainder of 6) Jane could put 18 cupcakes on each table so each table so they all have the same amount of cupcakes.
Answer:
25 x 6 = 150 then divided by 8 = 18.75.

A daycare is fencing in a grassy area to make a playground for kids. One sound of the playground will be directly along the building and is 40 feet in length.What will the width of the playground be if they have 170 feet of fencing to use?
Answer:
45 feet width
Step-by-step explanation: 4 fences required as given as one is already along the side of building and says 'fencing in '
40 ft lengths = 40 *2 = 80ft playground perimeter of only the lengths and then the widths is looked for so we label 40 feet length on rectangle Then ; (( perimeter subtracted by 2 lengths) /the amount of widths) = ((170-80) /2) = 90/2 = 45 feet =width then label width 45 feet
