z is directly proportional to x: z = kx.
If z is directly proportional to x and inversely proportional to y, then z = Kx/y.
When x= 6 and y = 6, z is 12. Find the constant of proportionality, K:
12 = K(6/6), or K = 12
Then, in general, z = 12x/y.
What is z when x=13 and y=10? z = 12(13)/(10) = 15.6 (answer)
Answer:
Step-by-step explanation:
do the thing times 2
Answer:
Step-by-step explanation:
If it is irrational, it can never be rational unless it is acted upon by something else like a power.
Pi, no matter what is done to it, can never be rational. Once a number is declared as irrational, that is what it remains.
Answer:
18 Weeks
Step-by-step explanation:
$39.50=17 + (5*x)
$39.50-17=17-17 + (5*x)
$22.5/5=(5*x)/5
It will take 4.5 months to save up. If each month has 4 weeks it will take 18 weeks
Answer:
8 phone cells
Step-by-step explanation:
We are told that he spent 14 minutes on the phone while routing 7 phone calls.
Now, we want to find the number of phone cells he will route for a total of 16 minutes.
Thus, by proportion using unit rates;. Number of minutes spent pet phone cell = 14 minutes ÷ 7 phone calls = 2 minutes per phone cell
Therefore, for 16 minutes, number of phone cells will be;
16 minutes ÷ 2 minutes per phone cell = 8 phone cells
