The value of V is 32 when p = 4 if the inverse variation equation is p=8/V option fourth is correct.
<h3>What is an expression?</h3>
It is defined as the combination of constants and variables with mathematical operators.
The question is incomplete.
The complete question is:
For the inverse variation equation p=8/V, what is the value of V when
p = 1/4
We have an inverse variation equation:
p = 8/V
Plug the value of p = 4 in the above expression, we get:
1/4 = 8/V
V = 8×4
V = 32
Thus, the value of V is 32 when p = 4 if the inverse variation equation is p=8/V option fourth is correct.

Total Squares = 10 × 10
= 100
Shaded Squares = 100 - (6×6)
= 64
Non Shaded = 6 × 6
= 36
Now Ratio of shaded portion is 64:100
= 16:25
Percentage = 64/100 × 100
= 64%

Answer:
10%
Step-by-step explanation:
The computation of the percentage of bulbs that switched on incandescent is as follows;
Let us assume the incandescent be I
And, the fluorescent be F
Now the equation is
0.4I + 0.9F = 0.8 (I+F)
0.41I + 0.9F = 0.8I + 0.8F
So here
0.4I = 0.1F
Now the percentage would be for incandescent in the case of switched on is
= 0.4I ÷ 0.8(I+F) × 100
= 0.1F ÷ 1F
= 10%
Answer:
The whale is at a depth 120 feet below the sea level.
Step-by-step explanation:
A grey whale is cruising at a depth of 233 feet below sea level. The depth below the sea level has the negative position, thus the initial position of the whale is -233.
It rises 73 feet, the position of the whale becomes 73 feet higher. This means we should add 73.
Then it comes up another 40 feet, so we need to add 40.
Mathematically,
The whale is at a depth 120 feet below the sea level.
