Answer:

Step-by-step explanation:

s = cost of senior ticket

c = cost of child ticket

System of Equations:

8s + 7c = 211

4s + 6c = 138

I used the elimination method and multiplied the second equation by -2

-8s - 12c = -276

add the above to the first equation and get

-5c = -65

c = 13

now find s

8s + 7(13) = 211

8s + 91 = 211

8s = 120

s = 15

Answer:

$\sqrt{8x-4}$

Step-by-step explanation:

Substitute x = g(x) into f(x) , that is

f(g(x))

= f(8x - 13)

= $\sqrt{8x-13+9}$

= $\sqrt{8x-4}$

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]

Answer-

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

Solution-

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

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

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

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

Total volume,

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

As we know,

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

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

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

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