Answer:
a - 8
b - 20
c - 40
answer - 40% of 20 is 8
Step-by-step explanation:
20 x .4 = 8
.4 is found by the 40 / 100
Answer:
i think H(5) plus the 50 $ but it may be wrong
Step-by-step explanation:
If H is 60 then 5 times is 300 plus the 50 he already had so it all adds up to 350
Answer:
Step-by-step explanation:
∠A = arctan(33/43) ≈ 37.5°
AB = √(43² + 33²) = √2938
Law of Sines
∠C = arcsin(sinA ⋅ AB/BC) ≈ 34.7°
Answer:
$69 is the total cost of the bill
Step-by-step explanation:
60(1.15)
60 is the cost of the bill, and the 1.15 is the added tax plus the previous $60.
Put 60(1.15) into a calculator and
$69
<span>center of mass = (0, 0, 96/13) exactly (0, 0, 7.3846) approximately.
The object described is a spherical cap for a sphere with a radius of 10. Since the sphere is centered at the origin, the center of mass will have X and Y coordinates of 0 and we only need to find the Z coordinate. The formula for the geometric centroid of a spherical cap is:
z = 3(2R - h)^2 / 4(3R - h)
where
z = distance from the center of the sphere
R = radius of sphere
h = distance from base of spherical cap to top of spherical cap
And for a spherical cap of uniform density, the geometric centroid is also known as the center of mass.
Since the sphere has a radius of 10 and is cut by the plane z=6, the value h will be 10-6 = 4. So substitute the known values into the formula:
z = 3(2R - h)^2 / 4(3R - h)
z = 3(2*10 - 4)^2 / 4(3*10 - 4)
z = 3(20 - 4)^2 / 4(30 - 4)
z = 3(16)^2 / 4(26)
z = 3(256) / 104
z = 768/104
z = 96/13
z ~= 7.384615385</span>
