Answer: 64\ ft^3

Step-by-step explanation:

Given

The dimension of the box is

\text{width w=}8\ ft\\\text{height h=}2\ ft\\\text{length l=}4\ ft

Space occupied by the box is equal to its volume i.e.

The volume of the box is 64\ ft^3.

At the beginning of the spelling bee there were 60 participants. One-third of the participants were eliminated during the first
lesya [120]
Participants = 60
.
First round:
1/3 of 60 = 20
or
60 x 1/3
= 60/3
= 20
60 - 20 = 40
There are 20 participants that are eliminated on the first sound and 40 participants to move on to the second sound.
.
Participants = 40
Second round:
1/4 of 40 = 10
or
40 x 1/4
= 40/4
= 10
40 - 10 = 30
There are 10 participants that are eliminated on the second round and 30 participants that is moving on to the next round.
.
Participants = 30
Third round:
1/6 of 30 = 5
or
30 x 1/6
= 30/6
= 5
30 - 5 = 25
There are 5 participants that are eliminated on the third round and 25 participants to move on to the fourth round.

Solve the literal equation below for y<br> a=9y+2/x
MrRissso [65]

Answer: y =\frac{ax - 2}{9x}

Step-by-step explanation: look for the lcm

a=\frac{9xy + 2}{x}

cross multiply

ax =9xy + 2

ax - 2 = 9xy

divide both sides by 9x

\frac{ax - 2}{9x}   = \frac{9xy}{9x}

y=\frac{ax - 2}{9x}
