s344n2d4d5 [400]

Answer:

Step-by-step explanation:

Circumference=25\frac{1}{7}\\\\\i \pi*d=\frac{176}{7}\\\\\frac{22}{7}*d=\frac{176}{7}\\\\d=\frac{176*7}{7*22}\\\\d=8

r = 8/2 = 4 inches

Area=πr²

=\frac{22}{7}*8*8\\\\=\frac{1408}{7}\\\\=201.14 inches^{2}

Norton can mow the large lawn in about 5 hours. When he works with
astra-53 [7]

Answer:

7.5 hours

Step-by-step explanation:

The key here is to find out how much can be done in the same amount ot time

the least common multiple of 5 hrs and 3 hrs is 15hrs

In 15 hours:

- At 5 hours per lawn Norton could mow 15/5 = 3 lawns

- At 3 hours per lawn together thay could mow 15/3 = 5 lawns

In 15 hours Jesse would mow 5 - 3 = 2 lawns

15 hours/ 2 lawns = 7.5 hours per lawn

7.5 hours

--------------------

Here's the math

1 lawn/5hrs + x = 1 lawn / 3hrs

1/5 + x = 1/3

Subtract 1/5 from both sides

x = 1/3 - 1/5

x = 5/15 - 3/15

x = 2/15

x = 2lawns/15 hrs

15hrs/2lawns = 7.5 hrs per lawn

7.5 hours

Fiona wants 6 red, 3 green and 3 yellow buttons on her dress. All buttons must be placed along a straight vertical line with no
elixir [45]

The appropriate method to use in solving the given question is permutation. Then, the numbers of ways to arrange the buttons is 1320 ways.

In the given question, the order of arrangement is important, so that the number of ways that Fiona could order the buttons can be determined by permutation method.

i.e _{n}P_{r} = \frac{n!}{(n - r)!}

Red      6

Green   3

Yellow  3

Total     12

Since no two neighbouring buttons of the same colour is allowed, then 3 buttons would be arranged at a time.

Thus, n = 12 and r = 3;

_{12}P_{3} = \frac{12!}{(12 - 3)!}

      = \frac{12!}{9!}

      = \frac{12*11*10*9!}{9!}

      = 12 x 11 x 10

_{12}P_{3} = 1320

Therefore the buttons can be arranged in 1320 ways without two neighbors having the same colour.
