Answer:
125 %
Step-by-step explanation:
Computers purchased in the last month = 8
By the middle of the current month, 8 more computers than the last month were purchased. This means, total number of computers purchased by middle of current month = 8 + 8 = 16
Number of computers purchased by end of current month = 2
So,
Total computers purchased by current month = 16 + 2 = 18
We have to find the percentage increase in the number of computers from last month's purchases to the end of this month's purchases. The formula for percentage change is:
Here, Original Value is the number of computers from last month and New Value is the number of computers from current month. Using the values in the formula, we get:
Thus, there was a 125% increase from last month's purchases to the end of this month's purchases
Answer:
D. 360 in.²
Step-by-step explanation:
<em>Since all the answers are labeled as in.², we know that we have to find the area of the rectangular prism. The formula for area of a rectangular prism is: </em><em>lwh </em><em>(length x width x height).</em>
<em>l = 12</em>
<em>w = 6</em>
<em>h = 5</em>
12 x 6 x 5 = 360

Answer:
f^-1(x) = (x +4)/3
Step-by-step explanation:
The inverse function is found by swapping x and y, then solving for y.
y = 3x -4 . . . . . function y = f(x)
x = 3y -4 . . . . . inverse relation
x +4 = 3y . . . . add 4
(x +4)/3 = y . . . divide by 3. This is the inverse function
f^-1(x) = (x +4)/3
