What is the volume of the prism given below?
KatRina [158]
Hi there!

Similar to the area of a triangle, it is 1/2 the area of a square. Therefore, we can multiply the base x height x length and divide it by 2 to find the volume of this figure.

WORK:
(6 x 8 x 19) / 2 = 456

ANSWER: 
Option B - 456 units^3

Hope this helps!! :)

PLZ HELP STUCK ON THIS QUESTION 4a + 6b = 24 6a - 12b = -6 Given the equations what is the value of a+b? PLZ HELP WILL MARK BRAI
Paul [167]

Answer:

a + b = 5

Step-by-step explanation:

To solve this system of equations, we can use a strategy called elimination, which is when we get rid of a variable by adding/subtracting two equations.

Firstly, we want to make sure the absolute value of the coefficients that equal.

Lets eliminate b:

4a + 6b = 24

Multiply both sides by 2:

8a + 12b = 48

We also have:

6a - 12b = -6.

Now lets add that with

8a + 12b = 48

-> 6a + 8a + 12b - 12b = 48 -6

-> 14a = 42

-> a = 3

Now that we know a, lets plug it into one of our original equations:

4(3) + 6b = 24

12 + 6b = 24

6b = 12

b = 2

Finally, add the two values we found:

a+b = 2+3= 5

Nicole is playing a video game where each round lasts \dfrac{7}{12} 12 7 ​ start fraction, 7, divided by, 12, end fraction of an
Harrizon [31]

Total number of hours she schduled to play the game = 3\frac{3}{4} hours.

Let us convert mixed fraction into improper fraction

3\frac{3}{4} = \frac{3*3+4}{4} = \frac{13}{4} \ hours.

Duration of each round = \frac{7}{12}.

In order to find the number of rounds Nicole can play, we need to divide total number of hours by duration of each round.

\frac{13}{4} ÷ \frac{7}{12}

Converting division sign into multiplication flips the second fraction.

=\frac{13}{4} \times \frac{12}{7}

Crossing out 12 by 4, we get 3 on the top of second fraction.

=\frac{13}{1} \times \frac{3}{7}

=\frac{39}{7}  = 5.57...( Approximately).

Because problem is about number of rounds.

So, total number of round would be 5.
