B is the correct answer, i believe
Answer:
9
Step-by-step explanation:
Initial number occurs when x = 0
so its 9(2)^0
= 9*1
= 9 answer
Answer:
784
Step-by-step explanation:
A = 1/2ap A = area , a = apothem , p = perimeter
a = 1/2s a = apothem length , s = side length
14 = 1/2s , 14(2) = 1/2s(2) , 28 = s
p = 4(s) , p = 4(28) , p = 112
A = 1/2ap , A = 1/2(14)(112) , A = 784
or
A = s^2 , A = 28^2 , A = 784
Let's define the following variable:
t = total time it takes to assemble a shelving unit together.
We then have the following equation:
1/5 + 1/3 = 1 / t
Solving the equation we have:
3t + 5t = 15
8t = 15
t = 1,875 hours
Answer:
the time it takes for worker A and worker B to assemble a shelving unit together is:
t = 1,875 hours
