How many sides does a regular polygon have if each exterior angle has a measure of 15° ?

Answer:

x= 13.25

Step-by-step explanation:

If you simplify that it becomes 8x-6= 100

Then, if you rearrange it, its 8x= 100+6 or 8x=106

So that means x= 13.25

Answer:

a) 207,360 ways

b)8,709,120  ways

Step-by-step explanation:

Total number of subjects= 3

Number of mathematics books = 4

Number of physics books = 6

Number of chemistry books = 2

Part a:

Number of possible arrangement s= 3! 4! 6! 2!= 6*24*720*2= 207360 ways

In this we have included 3! because the books have to be placed in such a manner that the books in each particular subject must all stand together.

Part b:

Similarly the mathematics books must stand together so they are treated as

The total number of books will be

Physics books + Chemistry books+ Mathematics books= 6+2+1(treated as single) = 9

But there are 4 different mathematics books so these can be arranged in 4 ways.

Total number of ways in which these books can be arranged = 9! 4!= 8709120  ways.

Answer:

5/2

Step-by-step explanation:

Answer:

Step-by-step explanation:

The fill ups is

Smallest number, a= 9

Largest number, b= 100

a²+ 2ab+ b² can be written as 9²+ 2. 9. 100 + 100²

A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminates in mathematics.

Given:

Here the smallest number can be taken as 9.

and, here we have 109² then the number can be split as 100 + 9.

Thus, the largest number is 100.

Now, a²+ 2ab+ b² can be written as 9²+ 2. 9. 100 + 100² which can be simplified as 11881.

Answer:

19

Step-by-step explanation:

1st you will use a^2+b^2=c^2

next you plug them  in so it would be a^2+16^2=25^2

next you would solve it to a^2+256=625

then you would get 369  and square root it  

and your answer will be  19.2.

Step-by-step explanation:

F is not a subset of G because not every element in F lives in G. Even through 56, 1 and 2, all live in G, and are elements of F, 777 is an element of F but is not an element of G.

(If there is a typo, and every element in F is in fact an element in G, then the answer would be yes, F is a subset of G)

We can see that element 777 is not in set G. Hence the set F is not a subset of set G.

For the given set F={56,777,1,2}, we can see that the element 777 is not in the set G. Hence the set F is not a subset of set G.

A, B, and C are not linear functions

D would be y=x/2

If you graphed y=x/2, you would get the points (4, 2), (7, 3.5), (8, 4), and (10, 5)

It's more obvious if you notice that y is half of x.

Answer:

jesse or sam i think its sam by a little bit.

Step-by-step explanation:

Answer:

Sam

Step-by-step explanation:

Find all of their speeds to find how far they will go in 1 minute, by dividing the number of kilometers by the number of minutes:

Sam

4.2/6

= 0.7 km/min

Amanda

3.2/8

= 0.4 km/min

Jesse

3/5

= 0.6 km/min

Since 0.7 is the greatest number, that means Sam is the rider that will go the farthest in one minute.
