X and y are opposite angles therefore x=y.
The sum of the measures of the interior angles of a triangle is 180 degrees:
y+55+30=180
y=180-55-30
y=95 degrees
so:
x=y=95 degrees
Answer:
The formula for the volume of a cone is V=1/3hπr².
The steps for dividing fractions are:
Keep
Flip
Change
As in, keep the first fraction the same (we can write 7 as 7/1 to make it a fraction), flip the second fraction upside down, and then change the division symbol to a multiplication symbol. This gives you:
7/1 × 5/6
And to multiply fractions, you multiply across, which means that you do (7 × 5 = 35)/(1 × 6 = 6). Your answer, therefore, is 35/6, or, as a mixed number, 5 5/6. I hope this helps!
Bearing in mind that the
average rate of change is the
slope, then we can pick any two points from the table to get the slope,
Answer:
Step-by-step explanation:
<u>Given system</u>
<u>Solve by elimination, subtract the equations and solve for y:</u>
- 18x + 6y - 18x - 22y = 30 - 14
- -16y = 16
- y = -1
<u>Find x by substituting y:</u>
- 18x + 6(-1) = 30
- 18x - 6 = 30
- 18x = 36
- x = 36/18
- x = 2
<u>The answer is</u>: (2, -1)
