Answer:
It would be A
Step-by-step explanation:
The other answers do not make sense.
First of all: Area= length x width.
Two of the options were larger than 49.7, so we could cross those out
Then, we look at A and B.
46.2 x 3.5 = 161.7, which is WAY larger than 49.7.
Since we have no option left to test, we can test A:
14.2 x 3.5= 49.7
Now we cam be sure that the answer is 14.2, or, A.

Answer:
Problem-solving requires persistence as much as it requires ingenuity. When you get stuck, or solve a problem incorrectly, back up and.

Step-by-step explanation:
The ratio is 6w = 4f.
Multiply both sides by 3/2 to get 6 cups of flour, and we have:
6*3/2 w = 4 * 3/2 f
18/2 w = 12/2 f
9 w = 6 f
So 9 cups of water.
Answer:
The exponential decay function.
Step-by-step explanation:
The exponential decay function can be used to model the amount of medicine in a person's bloodstream after a certain amount of time. When a drug is administered to a persons bloodstream perhaps through intravenous injections, the exponential decay function measures the initial concentration of the drug and then after a time t, it notes the new concentration. To obtain the result, the equation below is used:
C(t)=C(0)e^(-kt)
where,
k= constant
C(0)= Initial concentration after the injection
C(t)= Concentration after time t
