The answer that you are looking for, for this question is D. Four thirds
The percent of change can be calculated by finding the difference between the two volumes and then dividing by the original volume.
0.64 - 0.34 = 0.3
0.3/.34 = 0.882
This is approximately an 88.2% increase in volume.
Answer:
D: {9, 21, 33}
Step-by-step explanation:
Ken worked 2, 8 and 14 hours on 3 separate days.
For working 2 hours, his earnings were f(2) = 2(2) + 5, or 9;
For working 8 hours, his earnings were f(28) = 2(8) + 5, or 21; and
For working 14 hours, his earnings were f(14) = 2(14) + 5, or 33
Thus, the range of this function for the days given is {9, 21, 33} (Answer D)
Answer:
Firstly, it is important to note that the multiplication of matrices is done in this way:
Columns x Rows or viceversa
Now, two matrices can be multiplied only if their dimensions are compatible, which means that the number of columns in the first matrix must be equal to the number of rows in the second matrix.
In other words:
Two matrices A and B are said to be multiplies if the number of columns in A coincides with the number of rows in B.
In this context, the correct option is:
![\left[\begin{array}{c}1&-1\end{array}\right] \left[\begin{array}{cc}0&4\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D1%26-1%5Cend%7Barray%7D%5Cright%5D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D0%264%5Cend%7Barray%7D%5Cright%5D)
Where A is:
![\left[\begin{array}{c}1&-1\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D1%26-1%5Cend%7Barray%7D%5Cright%5D)
And B is:
![\left[\begin{array}{cc}0&4\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D0%264%5Cend%7Barray%7D%5Cright%5D)
As you can see, the number of columns in A coincides with the number of rows in B
Answer:
$230.65
Step-by-step explanation:
$179 marked down by 35 % = $116.35
computer mount= $99
cell holder= $56
total= $271.35
marked down by 15% = $230.65 (230.6475)
