Note that f(1) = 6(1)+2 = 8.  Next, evaluate g(x) at x=8:  g(f(1)) = g(8) = 2(8) + 4/5, or 16 4/5.

Which equation can you use to solve for the volume of the cake?
lesantik [10]

Answer:

C. (40 × 60 × 10) + (30 × 60 × 10) = V

Step-by-step explanation:

Picture of the cake can be found in the attachment below :

To solve, we resolve the cake into two distinct boxes :

The lower which is lateral sits parallel, whose volume, = (length * width * height) = (60 * 30 * 10)

And the other which sits vertically ;

Volume = (length * width * height) = (10 * 60 * 40)

Then, we add;

Overall volume:

(60 * 30 * 10) + (10 * 60 * 40)

A tunnel is 300 feet deep and makes an angle of 30 with the ground .
Goshia [24]

Answer:

\boxed{C.\:\: 600\:feet}

Step-by-step explanation:


The tunnel, the ground and the depth of the tunnel form a right angle triangle.

The length of the tunnel is the hypotenuse of the right triangle that has been formed.


Let the length of the tunnel be m\: feet.


Using the sine ratio, we obtain;


\sin(30\degree)=\frac{Opposite}{Hypotenuse}


The length of the opposite side is 300\:feet


We substitute the given values to obtain;


\sin(30\degree)=\frac{300}{m}


\Rightarrow \frac{1}{2}=\frac{300}{m}


We cross multiply to obtain;


m=300\times2


m=600\:feet


Therefore the correct answer is C.

A rectangle with a length of 6 inches and a width of 1 foot has a perimeter of 14 inches.
Pachacha [2.7K]
The length is 6 inches.
The width is 1 foot = 12 inches.

The perimeter is  (6 + 12 + 6 + 12) = 36 inches (3 feet) .

"14 inches" is false.
