Answer:
The information given is not enough to determine their ages explicitly, so, here their ages are given in terms of Anna's age, which is the best that could be determined.
Anna's age = x years
Robert's age = (x - 11) years
Sara's age = (x - 9) years
David's age = (x - 1) years
Step-by-step explanation:
Let Anna be x years old.
Anna's age = x
Because Anna is 11 years older than Robert, we can say Robert's age is Anna's age minus 11.
Robert = x - 11
But Robert is 2 years younger than Sara, we can say Sara's age is Robert's age plus 2
Sara = (x - 11) + 2
= x - 9
David is 8 years older than Sara, we can say David's age is Sara's age plus 8.
David = (x - 9) + 8
= x - 1
Answer:
x = 3/4
Step-by-step explanation:
Simply add 1/4 to both sides of the equation to isolate <em>x</em> and to get your answer.
x = 1/4 + 1/2
x = 1/4 + 2/4
x = 3/4 or 0.75
Answer:
Option B
Step-by-step explanation:
Slope of a graph: 
y moves up by 1 unit and x moves right by 2 units
247,039 rounded to the nearest thousand is 247,000
Answer:
Volume of the given oblique cylinder = 36π units³
Step-by-step explanation:
Volume of the oblique cylinder = πr²h
Here, 'r' = Radius of the circular base
'h' = Height of the cylinder
For the given oblique cylinder,
Radius of the circular base = 3 units
Height of the cylinder = 4 units
Volume of the cylinder = π(3)²(4)
= 36π units³
Therefore, volume of the given oblique cylinder = 36π units³
