Divide each by 100. You get the ratio
765 : 1000
Now divide by 5
153 : 200
You can use this or
0.765 : 1
7 - 9w = - 29
Subtract 7 from both sides
- 9w = - 36
Divide by - 9 on both sides
w = 4
It is the third one out of all 4
Answer:
Step-by-step explanation:
The formula for finding the total measure of all interior angles in a polygon is: (n – 2) x 180. In this case, n is the number of sides the polygon has. Some common polygon total angle measures are as follows: The angles in a triangle (a 3-sided polygon) total 180 degrees.
Answer:
The solutions are (0, 4) and (0, -4)
Step-by-step explanation:
Solve this system using substitution:
Take the negative of the first equation and add the result to the second one:
-x^2 + y^2 = 16 becomes x^2 - y^2 = -16
Then:
x^2 - y^2 = -16
-2x^2 + y^2 = 16
------------------------
-x^2 = 0, so x must be 0.
By the first equation, if x = 0, -(0)^2 + y^2 = 16, or
y^2 = 16, or y = ±4
The solutions are (0, 4) and (0, -4)
