Answer: 3054 in^3
Step-by-step explanation: The formula for the volume of a sphere is V = 4/3 pi r^3, where r is radius.
Since the diameter is 18in, the radius would be 1/2 or 9in, and plugged in V is
V = 4/3(3.1415)(9)^3
An hourglass is turned over with the top part filled with
sand. after 3 minutes, there are 855 ml of sand in the top half. after 10
minutes, there are 750 ml of sand in the top half. This can be represents a two
points ( 3, 855) and (10, 750) . using this to solve the slope m =
(750-855)/(10-3) = -15. And using one point the equation is y = -15x + 900.
Answer:
18
Step-by-step explanation:
Given that:
y∞ xz
y=kxz. Where k is constant
When z=196 and x= 2 then y= 7
7=(196)(2)k
7=392k
k=1/56
There fore y=(1/56)xz
When x=3 and z =336
y=(1/56)xz
y=(1/56)(336)(3)
y=18
Answer:
6 times
Step-by-step explanation:
well just divide 4.5 by 0.75 to get
Answer:
1.7 seconds
Step-by-step explanation:
we have
where
v is the initial velocity (in feet per second)
s represents the initial height (in feet)
In this problem we have
---> because the object is dropped
substitute
Remember that
When the chestnut hit the ground the value of H is equal to zero
so
For H=0
solve for t
therefore
The solution is t=1.7 sec
