Answer:
50
Step-by-step explanation:
If everyone scored 50, the average is just 50.
The math would also be:
50 + 50 + 50 + 50 + 50 / 5 = 250 / 5 = 50
Answer:
larger number=29;smaller number=18
Step-by-step explanation:
let assume the two numbers are X and Y
where X is the larger number and Y is the smaller number.
From the question the larger number is 7 less than twice the smaller number. in mathematical terms this can be denoted as;
X=2Y - 7→→→→→→ equation 1
Also it was stated in the question that the sum of the two numbers is 47 which can be denoted as;
X + Y = 47→→→→→→ equation 2
Now from equation 1, X is mathematically expressed as 2Y - 7. Having known this we substitute X as 2Y - 7 into equation 2 then we have 2Y - 7 + Y = 47.
collecting like terms we have
2Y + Y = 47 + 7
solving arithmetically we have;
3Y = 54
divide both sides by 3 we have;
Y = 18.
Now if you recall from equation 1;
X = 2Y - 7;
since we now know Y as 18 we substitute Y as 18 in equation one then we have;
X = 2(18) - 7;
X =36 - 7
X = 29.
Answer:
f(5)= 78.5. I hope this helps!!
It would be D because there are 6 angles of the shape meaning the smallest you could rotate it to be on the same shape is 60 degrees. Then you do that twice and point F will be where point D used to be.
Answer:
C. 1/√2
Step-by-step explanation:
cos∅ is adjacent over hypotenuse:
cos45° = 1/√2
cos45° = √2/2
Alternatively, if you learned and memorized your unit circle, cos(π/2) = √2/2
