Answer:
t = (C - 3*A)/B + 3
Step-by-step explanation:
Given in the question that,
the speed with which canoe travelled for first 3 hours = A
the speed with which he travelled for any and all time thereafter = B
As we do not know the values of A, B, or C, so the answer will be an expression for C in terms of A and B.
<h3>Formula to use</h3>
distance = speed x time
C = A*3 + B*(t-3)
Rearranging and solving for t
C - (A*3) = B*(t-3)
C - (A*3) = Bt - B3
C - (A*3) + B3 = Bt
t = C - (A*3) + B3 / B
or
t = (C - 3*A)/B + 3
Answer:
2 1/2 cups
Step-by-step explanation:
3 dozen muffins = 1 1/2 cups

<span>The question is on how many ways can a cooking club with 12 members select a president and a vice president among themselves. First, 12 of them are selecting a president and they can do it in 12 different ways, then, 11 of them are selecting a vice president and they can do it in 11 different ways. When we multiply 12*11 we get that the overall number of ways they can select a president and a vice president is 132. So the correct answer is D. 132.</span>
∠M=90°-23.1°=66.9° - it's a right answer.
