Answer:
50 + 1 + 
+ 
+ 
Step-by-step explanation:
This is the answer because:
1) 50 and 1 equal to 51
2) The fraction forms of a decimal number is: the decimal number/the decimal number place value
3) Therefore, the answer is 50 + 1 + + +
Hope this helps!

Answer: cos(76)</h3>
=========================================================
Explanation:
The original expression is of the pattern cos cos + sin sin. This pattern matches the second identity in the hint. Specifically, we'll say the following:
cos(A - B) = cos(A)cos(B) + sin(A)sin(B)
cos(A)cos(B) + sin(A)sin(B) = cos(A - B)
cos(94)cos(18) + sin(94)sin(18) = cos(94 - 18)
cos(94)cos(18) + sin(94)sin(18) = cos(76)
----------
We can verify this by use of a calculator. Make sure your calculator is in degree mode.
- cos(94)cos(18) + sin(94)sin(18) = 0.24192
- cos(76) = 0.24192
Both expressions give the same decimal approximation, so this helps confirm the two expressions are equal. You could also use the idea that if x = y, then x-y = 0. Through this method, you'll subtract the left and right hand sides and you should get (very close to) zero.
Answer:
[(a)^2-(4^2)](a+4)
Step-by-step explanation:
Answer:
In 25% of the games at least 55 points were scored.
Step-by-step explanation:
Percentage:
Number of desired outcomes multiplied by 100 and divided by the number of total outcomes.
In this question:
8 total games
In 2 at least 55 were scores.
100*2/8 = 100/4 = 25%
In 25% of the games at least 55 points were scored.
w=61, the equation is w=(456-a-b-c)/2, so the work would look like 456-132-94-108=122/2=61
