V= pi x r^2 x h
V/(pi x h)=r^2
square root of [V/(pixh)]=r
Answer:
The angles inside a hexagon add up to 720.
105 + 88 + 142 + 140 + 124 + x = 720
720 - (105 + 88 + 142 + 140 + 124) = x
720 - 599 = x
<h2>x = 121</h2>
Answer:
b)4 11/10
Step-by-step explanation:
Answer:
4 mph
Step-by-step explanation:
Let :
Boat speed = 20 mph
speed of current = x mph
Distance against current = 2 miles
Distance with current = 3 miles
speed against current will be ; 20 - x
speed with current will be ; 20 + x
Time =distance / speed against time against = time with current
Solving Mathematically ;
2/(20-x )=3/(20 +x)
2(20+x )= 3( 20-x )
40+2x = 60-3x
3x +2x=20
5x=20
x = 20 / 5
x = 4 mph
Speed of current = 4 mph
No, if you do the vertical line test( draw a vertical line on each graph line that hits the circle) if the lline touches more than one point AT ANY TIME it is not a function. So in this case it is not a function
