a sculpture is formed from a cylinder resting on top of a cuboid. the cylinder has a radius 40cm and height 70cm. the cuboid mea
frosja888 [35]

<u>Answer-</u>

\boxed{\boxed{\text{Mass}=10.0447256\ ton}}

<u>Solution-</u>

The dimensions of the cuboid is, 80×80×140 cm

So, its volume will be =80\times80\times140=896000cm³

The dimensions of the cylinder is, radius = 40cm, height = 70cm

So, its volume will be \pi r^2h=\pi\times40^2\times70=351792cm³

Total volume,

V=V_{\text{Cylinder}}+V_{\text{Cuboid}}\\\\=351792+896000\\\\=1247792\ cm^3

As we know,

\Rightarrow \text{Density}=\dfrac{\text{Mass}}{\text{Volume}}

\Rightarrow \text{Mass}=\text{Density}\times \text{Volume}

\Rightarrow \text{Mass}=8.05\times 1247792=10044725.6\ g

\Rightarrow \text{Mass}=10044725.6\times 10^{-6}=10.0447256\ ton

Suppose that in a normal half hour of practice, a tennis player expends 280 calories of energy.
sertanlavr [38]

Answer:

308 Calories

Step-by-step explanation:

So we start off with 280 as usual, but I will focus on the percent. The given percent is 110% "effort". What we would need to do here is, Firstly, change the percent into a decimal, and this is done by moving the decimal spot of 110%. What I mean is that 110.% and you move that little period over 2 times to the left and also remove the percent as for now because we will not need it. After that you would get 1.10. This is what we will multiply by. So if we did 280x1.10 it equals 308, and that is how I got 308

Hope this helps!

Find the value of x if 7,x and 11 are in A.p.​
krok68 [10]

Answer:

x = 9

Step-by-step explanation:

since the terms are in AP then there is a common difference between consecutive terms, that is

a₂ - a₁ = a₃ - a₂ ( substitute values )

x - 7 = 11 - x ( add x to both sides )

2x - 7 = 11 ( add 7 to both sides )

2x = 18 ( divide both sides by 2 )

x = 9
