B. The girl would have to use less force because she is using a simple machine, or a lever. The lever makes it easier to lift the rock because the rock is closer to the fulcrum.
36/63 in its simplest form is 4/7
Have a great day! =)
The circumference = 2×pi×radius
the small = 2×3.14×4 = 25.12 inches
the medium = 2×3.14×5 = 31.4 inches
the large = 2×3.14×6 = 37.68 inches
<span>Given:
family travelled 25 miles in 30 minutes or 50 miles /hr
current time 3.00 pm.
total distance=225 miles.
solution:
speed = distance * time
time = distance/spedd
= 225/50
time = 4.5 hours.
reaching time= 3 hours +4 hour 30 minutes= 7.30 pm</span>
Step-by-step explanation:
If it's a straight line the use formula
m= gradient of line
c = y-intercept
we know that y-intercept is 4 so coordinate is
(0,4)
Equation also passes (2,10)
Use both coordinate to find gradient
m= vertical distance / horizontal distance
= (10-4) / (2-0)
= 3
y = 3x + 4
