Answer:the company bought 12 computers and 4 printers.
Step-by-step explanation:
Let x represent the number of computers that the company bought.
Let y represent the number of printers that the company bought.
The company buys a total of 16 machines. It means that
x + y = 16
Each computer costs $550 and each printer costs $390. If the company spends $8160 for all the computers and printers that was bought, it means that
550x + 390y = 8160 - - - - - - - - - - 1
Substituting x = 16 - y into equation 1, it becomes
550(16 - y) + 390y = 8160
8800 - 550y + 390y = 8160
- 550y + 390y = 8160 - 8800
- 160y = - 640
y = - 640/ - 160
y = 4
Substituting y = 4 into x = 16 - y, it becomes
x = 16 - 4
x = 12
Answer:
5670 cm^3 or 5670cm cubed
Step-by-step explanation:
Original sides-
12, 15, 18
After increasing by 3-
15, 18, 21
Finding the volume of a rectangular prism is length*width*height.
=15*18*21
=270*21
=5670
Therefore, the volume of the new prism is 5670cm cubed.
Hope this helped^^
Given:
v = 150d
v represents company's production for the coming year
d represents the number of days
150 is the daily production
<span>The rate of change of the function representing the number of vehicles manufactured for the coming year is CONSTANT (150) , and its graph is a STRAIGHT LINE . So, the function is a LINEAR function. </span>

Answer:
January has the greater MAD.
Step-by-step explanation:
The MAD of January is 8. You can figure this out by finding the mean of the data (adding them all together then dividing by the number of data points), then finding the distance between each data point and the mean. You then will add all the distances together, then divide by the number of data points. The MAD of July is 2.5. See above for the process.
