Please help me with this question

Dafna1 [17]

Answer:

422 cm²

Step-by-step explanation:

Surface area of the composite figure = (surface area of the upper cuboid + surface area of lower cuboid) - 2(base area of the lower cuboid)

Surface area of composite figure = $(2(lw + lh + hw)) + (2(lw + lh + hw)) - 2(l*w)$

Upper cuboid has the following dimensions:

$l = 4, w = 3, h = 8$

Lower cuboid has the following dimensions:

$l = 10, w = 7, h = 5$

Plug these values into the formula

Surface area of composite figure

$= (2(4*3 + 4*8 + 8*3)) + (2(10*7 + 10*5 + 5*7)) - 2(4*3)$

$= (2(12 + 32 + 24)) + (2(70 + 50 + 35)) - 2(12)$

$= (136 + 310) - 24$

$= 446 - 24 = 422$

Surface area of composite figure = 422 cm²

A bird is sitting on a train A moving at a speed of 40 kmph. It sees another train B at a Distance of 200 ms with Speed of 60 km

Aloiza [94]

Solution:

Two trains are moving in opposite direction with Speed 40 kmph and 60 kmph. Make train B stationary and then take the Speed of train A relative to the train B. So relative Speed of train A = 40 + 60 = 100 kmph. Before it crashes into the stationary train B it has to travel a Distance of 200 m which it will do in (0.2/100 ) hours. During this duration, the average Speed of bird has been 10 kmph i.e. before the crash total Distance covered by the bird = 0.2 * 10/100 km = 20 meters.

Jeremy bought a new truck for $32,000. The value of the truck after t years can be represented by the formula V = 32,000(.8)^t.

blondinia [14]

$6700=32000(0.8)^t$
divide both sides by 32000
$\frac{67}{320}=0.8^t$
take the ln of both sides
$ln( \frac{67}{320})=ln(0.8^t)$
using the property that $ln(a^b)=b(ln(a))$
$ln( \frac{67}{320})=t(ln(0.8))$
divide both sides by ln(0.8)
$\frac{ln( \frac{67}{320}) }{ln(0.8)} =t$
use calculator
7.00728=t
so in about 7 years
