Answer:
The answer is 12 units.
Step-by-step explanation:
Looking at the figure we see that

and

Now from equations (1) and (2) we have values for
and
so we put those into the equation (3) and get:



Therefore the answer is 12 units.
Answer:
The probability would be 2/5
Step-by-step explanation:
There is five numbers on the spinning and the chance of getting one certain number would be 1/5, and if you add the two probabilities together would be 2/5, I am pretty sure.
Distribute the 3 to the parentheses. Q=3r+3/r
Next multiply both sides by r to get rid of the division sign.
Qr=3r+3
Subtract 3r on both sides and you get Qr-3r=3
Since both numbers have an r in it, we can factor out the r
r(Q-3)=3
Then we divide Q-3 on both sides
r=3 / (Q-3)
45.5 acres of land can be farmed and 24.5 cannot be farmed.
