Answer:
x = 12
Step-by-step explanation:
Complementary angles add up to have a sum of 90 degrees. We can create an equation and solve for x.
3x + 6x - 18 = 90
~Simplify
9x - 18 = 90
~Add 18 to both sides
9x = 108
~Divide 9 to both sides
x = 12
Best of Luck!
Answer:
t=-13/5
Step-by-step explanation:
1/4t+3/5=2/5
-t
5/4t=-1/5
t=-4/25
Diameter(d)=8 in.
radius(r)= d/2= 4 in.
height(h)= 3r = 3(4) = 12 in.
Volume=
<u /><em>
r </em>²
<em>h
=</em>(3.14)(4)²(12)
=(3.14)(16)(12)
=602.88 in.
Therefore, the volume of the cylinder is 602.88 in.
Answer:
The slope is -8 and the y intercept is -6
Step-by-step explanation:
The first numbers are the slopes and the one after that is the y intercept. ALWAYS
Use the equation y2-y1/x2-x1 then simplify
