It is c. 216 in³
to answer the problem, u must know the formula V=LxWxH (volume= length x width x height)
L=12
W=6
H=3
so, 6x3x12= 216 in³

A group of adults and students went on a class trip to Washington, DC. The number of male students was 1 more than 7 times the n

algol [13]

Alright.
So let's say the number of adults is x.
Therefore, the number of boys is 7x + 1.
And then the total amount of girls is 3.5x + 0.5
So then:
x + 7x + 1 + 3.5x + 0.5 = 82
11.5x + 1.5 = 82
11.5x = 80.5
x = 7
So now we can figure out the number of male and female students.
Male students = 7x + 1
7*7 + 1
49 + 1
50
Male Students = 50
Female students = half of 50
50/2 = 25
Female Students = 25

Adam built a toy box for his children’s wooden blocks.

navik [9.2K]

Answer:

A. 162

B. 128

Step-by-step explanation:

We have wooden cubes of 2 in of side.

A. If the box is 18 x 12 x 6 in., in the base (18 x 12), we can fit 54 cubes:

$\dfrac{18}{2}\cdot \dfrac{12}{2}=9\cdot 6=54$

As the height is 6 in, we can fit 6/2=3 layers of 54 cubes in the box, se we can fit 162 cubes:

$B=3\cdot54=162$

B. If we have a box with measures 16 x 9 x 9 in., and the base is 16x9 in, we can fit (16/2)*(9/2)=8*4=32 cubes per layer.

Note that in the 9 in side we can only put 4, as we need 10 in to fit 5 cubes (we can not cut them).

In the same way, as we have 9 in of height, we can fit 4 layers of 32 cubes, so this is a total of 128 cubes:

$B=4\cdot32=128$

HELP! PLEASE!!!!!!!!!

natali 33 [55]

Answer:

46/3 or 15.3

Step-by-step explanation:

After rounding to the nearest integer, we have:

3(x - 7) = 25.

Dividing both sides by 3, to isolate (x - 7), we get x - 7 = 25/3.

Adding 7 to both sides, we get x = 25/3 + 7, or x = 25/3 + 21/3, or x = 46/3. This is 15 1/3, which is closest to the last given possible answer (15.3).
