Answer:
the answer is 30
Step-by-step explanation:
(6+4) * 3
Do what is in the parenthesis!
(6+4) = 10
Then do the *3
10*3 = 30!
Hope this help! Goodluck!
Answer:
266.6666667
Step-by-step explanation:
200 divided by 3 equals 66.66666667. Then you would multily that by 4, which equals 266.6666667. So the answer is 266.6666667.
Answer:
√3
Step-by-step explanation:
From the formula used in calculating Friction, we have:
Frictional Force = coefficient of Friction × Reaction
i.e Fr = μ × R
Resolving Frictional Force and Reaction of a body moving with on an Inclined plane,
Frictional Force = mass × g × sin a
where a = to the angle given
Reaction = mass × g × cos a
Therefore,
mass × g × sin a = μ × mass × g × cos a
mass and g cancels out on both sides.
Therefore,
sin a = μ × cos a
make "μ" subject.
μ = sin a/cos a
(recall: tan a = sin a /cos a)
μ = tan a
recall a = angle given = 60°
μ = tan 60°
μ = √3
or simply recall that
μ = tan a
μ = tan 60°
μ = √3
Answer:
126π ≈ 395.8
Step-by-step explanation:
Including the bottom of the cone, the surface area is:
A = πr² + πrs
where r is the radius and s is the slant height.
A = π (6)² + π (6) (15)
A = 36π + 90π
A = 126π
A ≈ 395.8
Answer:
The answer becomes a multiple of the original fraction, which means that if you simplify the result, you will get the original fraction.
Ex:
2/5 * 9/9 = 18/45
18/45 = 2/5
