6 0

Answer:

Volume = 288 in.³

Step-by-step explanation:

Volume of the solid = volume of the cube + volume of the square pyramid

V = a³ + ⅓*a²*h

a = 6 in.

h = 12 - 6 = 6 in.

Plug in the values into the volume formula

Volume = 6³ + ⅓*6²*6

Volume = 216 + 72

Volume = 288 in.³

A bag has green and purple marbles. Two-fifths of the marbles are green, and the rest are purple.
Musya8 [376]

The number of purple marbles in the bag are; 201 purple marbles

<h3>How to work out fraction of bar model?</h3>

We are told that Two-fifths of the marbles are green, and the rest are purple.

A) The image attached shows the bar model where the shaded parts denote the purple marble while the unshaded parts denote the green marbles.

B) We are told that there are 134 green marbles.

If the total number of marbles are x. Then;

(2/5)x = 134

x = 134 * 5/2

x = 335 marbles

Thus;

Purple Marbles = (3/5) * 335 = 201 purple marbles

(08.03)A set of equations is given below:
faltersainse [42]

Answer: Third option

-x + 2 = 3x - 4.

Step-by-step explanation:

One of the ways of solving a system of equations is by equating the equations and solving for one of the variables.

In this case we have the system:

y = -x + 2\\\\y = 3x - 4

Note that if y is equal -x + 2 and also y equals 3x - 4

Then logically -x + 2 must be equal to 3x - 4.

We write equality.

-x + 2 = 3x - 4.

Then the correct answer is the third option.

We can also solve for the variable x

-4x = -6\\\\4x = 6\\\\x = \frac{6}{4}\\\\x = \frac{3}{2}
