Answer: 10\sqrt{3}

Step-by-step explanation:

Since both radicals have the same index (square roots) then to multiply them you simply multiply the numbers under the square root signs and keep them there:

\sqrt{30} \sqrt{10}=\sqrt{300}

Then, to simplify the expression you can break down the number into its factors till you get a perfect square that you can get out of the square root. In this case, since 300 is divisible by 100, then we're going to break it down conveniently because 100 is a perfect square:

\sqrt{300}=\sqrt{3*100}=10\sqrt{3}

Answer:

10√3

Step-by-step explanation:

You separate √30 by √3·√10 and the other √10 cancelates the root leaving you with 10√3.

four 3 megawatt wind turbines can supply enough electricity to power 3000 homes. How many turbines would be required to power 55
fiasKO [112]

Answer:

The number of turbines is 74

Step-by-step explanation:

* Lets explain how to solve the problem

- Four 3 megawatt wind turbines can supply enough electricity

 to power 3000 homes

∴ The number of turbines is 4

∵ Each turbine give 3 megawatt

∴ The four turbines give ⇒ 4 × 3 = 12 megawatt

- This quantity give enough electricity to power 3000 homes

∴ The number of homes for the 12 megawatt is 3000

- We need to find how many turbines can cover enough electricity

  to power 55,000 homes, so we must to know the quantity of

  electricity that be enough to power 55,000 homes

* <em>Lets use the cross multiplication to solve the problem</em>

∵         megawatt    :     number of homes

                  12          :              3,000

                  ?            :            55,000

- <em>By using cross multiplication</em>

∴ ?=\frac{(55,000)(12)}{3,000}=\frac{660,000}{3000}=220

∴ The enough electricity to power 3000 homes = 220 megawatt

∵ Each turbine gives 3 megawatt

- Find the number of turbines divides the total megawatt by the the

  megawatt of one turbine

∴ The number of turbines = 220 ÷ 3 = 73.3

- If we take 73 only the electricity will not be enough to cover all

 homes, so we must to take 74 turbines

∴ The number of turbines is 74
