Answer:
The answer is 5 ft squared
Step-by-step explanation:
so you have the find the area of the circle first and you do that by starting with the formula which is
pi r2
the diameter is 2.45 so you divide that by to to get the radius and get 1.25
the you would multiply 1.25 times 1.25 times 3.14, and get 4.91 which rounds to by the nearest whole umber as 5 ft 2.
Answer:
33.5 minutes
Step-by-step explanation:
At 5 mL/min, the full can of coke will be emptied in ...
... (335 mL)/(5 mL/min) = 67 min
The can will be half-empty (and the other can will be half-full) in half that time,
... (67 min)/2 = 33.5 min
Answer:
Yes your friend is correct.
Step-by-step explanation:
This can become very complex when trying to explain but essentially, opposite angles like angle 4 and 6 or the 103 degree and angle 2 would have the same angle measurement. Since angle 2 and 6 are on the same straight line with lines a and b being parallel, we know that that angle 2 and 6 are equal. Since we know that angle 2 and the 103 degree angle are equivalent, we can conquer that angle 6 equals 103 degrees.
Since bot of the expressions in x are equal to y we can equate them as follows:-
6x + 9 = 7x + 7
9 - 7 = 7x - 6x
x = 2
and y = 6(2) + 9 = 21
THe answer is Choice B
