Answer:

b)668

Step-by-step explanation:

volume of the truck: 5000/7.48=668.45cu/ft

let d= the depth of the oil in the truck

5 *20*d=66.8.45

100d=66.8.45

d=668.45

so it would be b :)

LenKa [72]

Answer:

If\ old\ scale\ is\ taken:\ Length=45\ ft,\ Width=42\ ft\\\\If\ new\ scale\ is\ taken:\ Length=36\ ft,\ Width=33.6\ ft

Step-by-step explanation:

Older Scale:

2\ in=3\ ft\\\\\Rightarrow 1\ in=\frac{3}{2}\ ft\\\\Length=30\ in\\\\Length=30\times \frac{3}{2}\ ft\\\\Length=45\ ft\\\\Width=28\ in\\\\width=28\times \frac{3}{2}\ ft\\\\width=42\ ft

New scale:

4\ in=5\ ft\\\\\Rightarrow 1\ in=\frac{5}{4}\ ft\\\\Length=30\ in\\\\Length=30\times \frac{5}{4}\ ft\\\\Length=36\ ft\\\\Width=28\ in\\\\width=28\times \frac{5}{4}\ ft\\\\width=33.6\ ft

for triangle ABC find the measure of line a b given measurement of angle a is 55 measurement of angle B is 44 and b equals 68
S_A_V [24]
Use the Law of Sines:
 
  sin B              sin 81         sin 44
 ----------       = ----------- = --------------
  side AC            68            side AB

Then (side AB)(sin 81) = 68(sin 44), or


                                 68 sin 44          
 side AB =        ----------------------- =  47.83 units long
                                    sin 81
