The angles form a right angle, so make an equation where they add up to 90 degrees.
(c + 3) + (4c - 13) = 90
Combine like terms.
5c - 10 = 90
Add 10 to both sides.
5c = 100
Divide both sides by 5.
c = 20
7 because there is 7 zeros
-1.8h-0.7 You combine like terms.
Answer:
FG= 30
Step-by-step explanation:
Point G is on line Segment FH
Given
FH= 4x
GH= x
FG= 2x+10
If the point G is on the line FH then the total of the two line segement FG and GH must be equal to FH
FH= FG+ GH
Putting the values in the above equation:
4x= 2x+10+x
4x= 3x+10 Solving for x
10= 4x-3x
10= x
FG= 2x +10
FG = 2(10) +10 Putting the value of x
FG= 20+10
FG= 30
Check :
FH= 4x= 4(10)= 40
GH= x= 10
FG = FH- GH= 40-10= 30
Answer:
diameter(d)=8 in.
radius(r)= d/2= 4 in.
height(h)= 3r = 3(4) = 12 in.
Volume=r ² h
=(3.14)(4)²(12)
=(3.14)(16)(12)
=602.88 in.
Therefore, the volume of the cylinder is 602.88 in.
