Answer:160
Step-by-step explanation:first I did 40*100=4000 then I divide by 25 so I got 160
Answer:
Step-by-step explanation:
a) r = 10/2 = 5 feet
Area of floor =πr² =3.14*5*5 = 78.5 feet²
B) h = 3 foot
Volume of cylinder = πr²h = 3.14*5*5*3 = 235.5 cubic feet
Volume of hemisphere =2/3πr³= 2*3.14*5*5*5/3=261.67 cubic feet
Volume of space inside the observatory = 497.17 cubic feet
Answer:
28.85
Step-by-step explanation:
Plug the values in and solve.
G = 5u + 2y
G = 5(2.89) + 2(5.7)
G = 14.45 + 11.4
G = 25.85
Answer:
The ratio of the intensities is roughly 6:1.
Step-by-step explanation:
The intensity I() of an earthquake wave is given by:
<em>where P: is the power ans d: is the distance. </em>
Hence, the ratio of the intensities of an earthquake wave passing through the Earth and detected at two points 19 km and 46 km from the source is:
<em>where I₁ = P/4πd₁², d₁=19 km, I₁ = P/4πd₂² and d₂=46 km </em>
Therefore, the ratio of the intensities is roughly 6:1.
I hope it helps you!
Answer:She used 3.72 pints of blue paints for the wall
Step-by-step explanation:
Total Quantity of Blue and white paint =6.2 pints
Quantity of White paint =2/ 5 x 6.2 pints = 2.48 pints
Quantity of blue paint =Total Quantity -Quantity of White paint
=6.2 pints-2.48 pints
=3.72 pints
