Answer:
Center = (4, -5)
radius = 6
======================================================
Explanation:
The general template of any circle is
(x-h)^2 + (y-k)^2 = r^2
Rewrite the given equation into this form
(x-4)^2 + (y- (-5))^2 = 6^2
We can see that (h,k) = (4,-5) is the center and r = 6 is the radius.
Answer: 132 handshakes in total
Step-by-step explanation: 11x12 because one of them will be the one shaking hands with everyone else so he would have gotten 11 hands shaked so everyone would have gotten their hands shaked 11 times
To solve for x, the first thing to do is to distribute the 4 to (x-2). When you do this, you should get 4x-8=4x+10
Then, subtract 4x from both sides and then you are left with -8=10. Because -8 is not equal to 10, meaning the equation you are left with is not a true statement, the answer to this would be that there are no real solutions.
Answer:
7.5 hours
Step-by-step explanation:
both pumps works simultaneously to pump 160 gallons of water per hour.
With a total pond capacity of 1200 gallons, you get your answer by simply dividing the total capacity by the flow rate which gives us 7.5 hours.
note: if it is stated that the pumps where connected together on the same line (either in series or parallel) this will be a different calculation.
115*20=2300.
50*5=250
First mechanic 20 hours
Second mechanic 5 hours
