<span><span>27100</span>(60)=<span>815</span>=16<span>15</span></span> The 16 is how many minutes you have. If you were not given the seconds, we would have to say that we have a remainder of (1/5) of a minute. Since 1 minute is (1/60), one-fifth of that is (1/300). Now we would need to see how many seconds that gives us. 1 second is (1/3600) of a degree, so we would need to divide (1/300) by (1/3600). Doing this gives us: <span><span><span>1300</span>÷<span>13600</span>=<span>1300</span>(3600)=12</span></span>

Simply the imaginary number square root -45
Paraphin [41]

Answer:

3i\sqrt{5}

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

and \sqrt{-1} = i

Given

\sqrt{-45}

= \sqrt{9(5)(-1)}

= \sqrt{9} × \sqrt{5} × \sqrt{-1}

= 3 × \sqrt{5} × i

= 3i\sqrt{5}

Of the sundaes recently sold at Ice Cream Haven, 6 had nuts and 14 did not. Considering this data, how many of the next 10 sunda
Schach [20]

Answer:

3 sundaes will have nuts

Step-by-step explanation:

Note that the total number of sundaes so far is 20, 6 of which had nuts, and 14 didn't.

Therefore the fraction representing the sundaes with nuts would be 6/20 = 3/10.

The fraction without nuts would be 7/10.

The question is asking for you to predict the number of sundaes that will have nuts using these fractions. Out of 10 sundaes, 3 of them will have nuts.
