Answer:
2.63274768567
Step-by-step explanation:
First, note that 3.1415... is p, so 2(3.1415...) is 2pi and 4(3.1415...) is 4pi.
2pi and 4pi are full rotations, which will lead to the same cosine (i.e. cos(x) = cos (x+2pi) = cos(x+4pi) = ... = cos (x+2k*pi)).
So, the expression equals cos0.5 + cos 0.5 + cos0.5 = 3cos0.5 = 3(0.87758256189) = 2.63274768567
I hope this helps! :)
Answer:
2.- 100
Step-by-step explanation 1:
↑ As we can see, the only common multiple between 4 and 25 that is given to is 100.
Step-by-step explanation 2:
↑ Another way of knowing the answer is by using a fraction solving method. As we can see, the denominator is once again 100.

Answer:
The decimal point should be moved Six places to the right side because there are Six zeros in 10 to the power of 6.
Step-by-step explanation:
As we have to represent the number in the form of 
we need to move the decimal Six places towards left because there are Six zeros in i.e. 1000000. For this purpose we will add four zeros to the left of the number.
So the number in the format mentioned in question will look like -
0.00003405 × .
No, because then she would have to pay 21 dollars as a total and she only has 20.
Add adult plus Child,
5.75 + 11.25 = 17
add that to the book's price,
17+3.99= 2.99
it will exceed the budget by 99 cents.
I think it is 0 because I googled it.
