The angle of rotation is the smallest angle of rotation a polygon can make until it goes back to its original figure. This could be determined by dividing a whole revolution by the number of sides of the polygon. A whole revolution is 360 degrees. If we divide this by 15, the angle of rotation would be 24 degrees.

Bumek [7]

Answer:

9 days

Step-by-step explanation:

He sets his watch 12 seconds behind

For every day that passes it falls back another 1 second

So once it is 21 seconds behind all you have to do is subtraction to find the amount of days past

21 - 12 = 9

Since its 12 seconds behind already itll take 9 days to be behind 9 more seconds.

Answer:

80.

Step-by-step explanation:

Let C be the set of people who like cats and D the set of people who like dogs. Under the cardinality theorem you have

n(CUD) = n(C) + n(D) - n(CnD)[/tex], isolating the (C∩(D , you have n(C∩(D  = n(C) + n(D) - (C∪.As a total of 339 individuals, and 88 are those who do not like cats or dogs, then 251 of them are those who like cats or dogs. Then, n[tex](C∩(D  = 190 +141 -251 = 80

Answer:

y = 2(3)^{x}

Step-by-step explanation:

For the exponential function in the form

y = ab^{x}

Use ordered pairs from the table to find a and b

Using (0, 2 ), then

2 = ab^{0} ( b^{0} = 1 ) , thus

a = 2, so

y = 2b^{x}

Using (1, 6 ) , then

6 = 2b ( divide both sides by 2 )

b = 3

Thus the exponential function is

y = 2(3)^{x}

93 / 12 = 7.75

so Lester earns $7.75 a hour.

if he earns $62 how many hours did he work.

so 62 = 7.75 (h)

62/ 7.75 = 8

so he worked 8 hours.
