Find the number of permutations of the first 10 letters of the alphabet, taking 3 letters at a time.
allsm [11]

Answer:

720

Step-by-step explanation:

The permutation looks like this for that set of data:

_{10}P_{3}

and the formula to solve it like this:

_{10}P_{3} =\frac{10!}{(10-3)!}

which simplifies down to

_{10}P_{3} =\frac{10!}{7!}

Since every number less than 8 in the numerator cancels out with the denominator, we have

_{10}P_{3}=10*9*8

which equals 720

In a sale the price of lawnmowers are decreased by 16% Jude buys a lawnmower in the sale for £369.60 how much was the lawnmower
Stella [2.4K]

Answer:

Step-by-step explanation:

Jude paid 84% of the original price. That comes about because 369.60 is the price he paid which includes as 16% reduction.

84/100 * x = 369.60              Multiply by 100

84x = 36960                         Divide by 84

84/84 x = 36960/84

x = 440

So the original price was 440 pounds
