Answer:
12%
Step-by-step explanation:
There are a total of 175 units in an apartment complex.
Out of which, 154 units are occupied.
Now, we have to find the percentage of the apartment which are unoccupied.
So, the number of units that are not occupied is (175 - 154) = 21.
Hence, the percentage of the number of unoccupied units of the apartment complex will be (Answer)
The value of the constant of variation is 1/8 if the quantity m varies jointly with p and r when p is 2 and r is 4, m is 1.
<h3>What is directly proportional?</h3>
It is defined as the relationship between two quantity as the one quantity increases the other quantity also increases and vice versa.
We have a quantity m varies jointly with p and r.
Mathematically,
m ∝ p×r
After removing the proportional sign, a constant of proportionality encountered.
Let's c is the constant.
m = c(p×r)
If p = 2, r = 4, and m = 1
1 = c(2×4)
1 = 8c
c = 1/8
Thus, the value of the constant of variation is 1/8 if the quantity m varies jointly with p and r when p is 2 and r is 4, m is 1.

^^To solve you must use the fractional exponent rule.
I dont quite understand what the question is asking but thats what I have to help :)
(35 + 47 + 42 + x) / 4 = 50
(124 + x) / 4 = 50....multiply both sides by 4, cancelling the 4 on the left side.
124 + x = 50 * 4
124 + x = 200
x = 200 - 124
x = 76 <===
