None of these, but \sqrt{64}=8 so if 64 is an option than that's the correct option

You and a partner tend 3 machines that run continuously. One prints 200 plastic bottles per hour, one prints 180 plastic bottles
strojnjashka [21]
The first machine does 200 in 1 hour, so in 8.5 hours it will then do 200 * 8.5.

the second machine does 180 in 1 hour, so in 8.5 hours it will then do 180 * 8.5.

the third machine does 150 in 1 hour, so in 8.5 hours it will do then 150 * 8.5.

how many bottles will they all do in total on that time?

(200 * 8.5) + (180 * 8.5) + (150 * 8.5)

X squared plus 8 squared equals 9<br> What is X?
BabaBlast [244]

Answer:

x = i\sqrt{55} , -i\sqrt{55}

Step-by-step explanation:

x^2 + 8^2 = 9

Simplify the 8^2

x^2 + 64 = 9

Subtract 64 from both sides

x^2 = -55

Take the square root from both sides

x = +/- \sqrt{-55}

Simplify

x = i\sqrt{55} , -i\sqrt{55}

Hope this helps!

a six sided die is rolled 4 times in a row. What is the probability of getting 4 only on the last trial of this experiment?
hoa [83]
First, start of by saying what the probability of getting a 4 is, which is 1/6.
Now, this means the probability of not getting a 4 is 1-(1/6)=(5/6), since the total probability is 1.

After doing this, you should think about what it means to only get 4 on the last trial, the 4th trial.  It means that the probabilities of the 1st, 2nd, and 3rd trial were (5/6) each.  The 4th trial had a probability of (1/6).  So the probability would be calculated as following: ((5/6)^3*(1/6)=5^3/6^4.  You can use a calculator or your computer to find out that the probability is 125/1296.  

I hope this was helpful!

No explanation needed just the answer please
Otrada [13]

Answer:

53

Step-by-step explanation:

65x- 12  = 43x + 10

65x - 43x = 10 + 12

22x = 22

x = 22/22

<u>x = 1 </u>

(65x- 12) =

65 * 1 - 12 =<u> 53</u>

43x + 10

43 * 1 -12 = <u>53</u>
