3. The measure of an interior angle of a regular polygon is 140. Find the number of sides the polygon has.
Answer:
I hope this will help u
Step-by-step explanation:
Each interior angle of a regular polygon = 140 deg. So each exterior angle of the regular polygon = 180-140 = 40 deg. Hence the regular polygon has 360/40 = 9 sides.

What transformation rule would represent a shift of 3 units to the left 4 units down?
Group of answer choices
(x,y) –> (x – 4, y – 3)
(x,y) –> (x – 3, y – 4)
(x,y) –> (4x, 3y)
(x,y) –> (x + 3, y + 4)
Given:
Shift of 3 units to the left 4 units down.
To find:
The transformation rule.
Solution:
The rule of transformation is
[tex](x,y)\to (x+a,y+b)[/tex] ...(i)
Here, a<0 if the figure shifts a units left and a>0 if the figure shifts a units right.
Similarly, b<0 if the figure shifts b units down and b>0 if the figure shifts b units up.
If a transformation represents shift of 3 units to the left 4 units down, then a=-3 and b=-4.
Putting a=-3 and b=-4 (i), we get
[tex](x,y)\to (x+(-3),y+(-4))[/tex]
[tex](x,y)\to (x-3,y-4)[/tex]
Therefore, the correct option is B.

What is the equation of the following line?
Solve the system of equations using the elimination method and enter the value of y
4x - 5y = -9
- 4x + y = -7
Answer:
y = 4; x = 11/4
Step-by-step explanation:
4x - 5y = -9
-4x + y = -7
Add the two equations to eliminate x:
-4y = -16
-4y/-4 = -16/-4
y = 4
Plug in y for x
4x - 5y = -9
4x - 5(4) = -9
4x - 20 = -9
4x = -9 + 20
4x = 11
4x/4 = 11/4
x = 11/4

This article gives the formula for finding the sides of a 30-60-90 triangle. https://blog.collegevine.com/complete-guide-30-60-90-triangle/
The gist of it is that the hypotenuse is 1, the short side is 2, and the long side is root3. Since there was a 14 with the root3, I multiplied the 1 and 2 for the other sides by 14 to get 28 and 14.
Please solve

ASAP!!!
On a time crunch!!!!!
Answer: x = 0
Step-by-step explanation:
Subtract 6x^3+29x^2+47x+28 from both sides:
(2^2 + x + 4) (x - 7) - 6x^3+29x^2+47x+28
(6x^3+29x^2+47x+28)-6x^3+29x^2+47x+28
= -4x^3 - 14x^2 - 36x = 0
Now factor the left side:
-4x^3 - 14x^2 - 36x = 0
(-2x) (2x^2 + 7x + 18) = 0
Now set the factors equal to 0
-2x = 0 or 2x^2 + 7x + 18 = 0
x = 0

(a) Mary and Cynthia were building a cone-shaped sand castle. After some time, the diameter of
the sand shaped cone was 14 in. and the height was 15 in. What is the appoximate volume of the
sand cone rounded to the nearest tenth? (Show work!!) PLEASE HELP!
Answer:
[tex]\displaystyle V\approx 769.7\text{ in}^3[/tex]
Step-by-step explanation:
We are given that the diameter of the sand-shaped cone is 14 inches, and the height is 15 inches.
The volume for a cone is given by:
[tex]\displaystyle V=\frac{1}{3}\pi r^2h[/tex]
Where r is the radius and h is the height.
Since the diameter is 14, the radius is 7.
And we are given that the height is 15.
Therefore, the volume will be:
[tex]\displaystyle V=\frac{1}{3}\pi (7)^2(15)[/tex]
Use a calculator:
[tex]\displaystyle V\approx 769.7\text{ in}^3[/tex]
The volume of the cone is approximately 769.7 cubic inches.

How long is the base of the parallelogram?
Enter your answer as a decimal in the box
Answer:
8.2
Step-by-step explanation:
area=b*h
37.72=b*4.7
b=37.72/4.7
=8.2
Answer:
Step-by-step explanation:
Area of parallelogram= base×perpendicular height
37.72m²=base×4.6m
base= 37.72m²/4.6m²
base= 8.2m
A group of five students have a mean test score of "34.2." Another student has a score of 50. What is the mean average of all "six" students?
Answer:
The mean average of all "six" students is 36.83.
Step-by-step explanation:
Mean:
The mean is the sum of all scores divided by the number of scores.
A group of five students have a mean test score of "34.2." Another student has a score of 50.
This means that the sum is given by:
[tex]S = 5*34.2 + 50 = 171 + 50 = 221[/tex]
What is the mean average of all "six" students?
Sum of 6 students is 221. So
[tex]M = \frac{221}{6} = 36.83[/tex]
The mean average of all "six" students is 36.83.

Lamont's empty backpack weighs 2 1/2 pounds. He puts 4 notebooks in it that each weigh 15 ounces. How many pounds does Lamont's backpack weigh now?
The answer is 6.252 pounds.
2 1/2 as a decimal is 2.5, and 15 ounces is equal to 0.938 pounds. Since there are 4 notebooks, you multiply 0.938 by 4, which is 3.752. Now, you just add 2.5+3.752=6.252
