Answer:
5 bags of cement are required.
Step-by-step explanation:
Since to make concrete, the ratio of cement to sand is 1: 3, if cement and sand are sold in bags of equal mass, to determine how many bags of cement are required to make concrete using 15 bags of sand the following calculation must be done:
Cement = 1
Sand = 3
3 = 15
1 = X
15/3 = X
5 = X
Therefore, 5 bags of cement are required.

DISTANCE FORMULA
D=(SQRT(X2-X1)^2+(Y2-Y1)^2)
SQRT(1-(-1))^2+(3-(-1)^2)
SQRT((2)^2+(4)^2)
SQRT(4+16)
SQRT(20)
2SQRT(5)
Answer:
D
Step-by-step explanation:
I might be wrong, so somebody check my answer please. The open circle means that number is not included in the graph. So less than 8 would be D.
Well, you don't have any options.
But a mixed number for 12.16 would be 12 4/25. Hope it helps! :)
