Answer:
The numbers; 19.0 , 19.00 and 19.000 are same value as the number 19
Step-by-step explanation:
Here in this question, we simply want to write decimals which would have same value as the number 19 when written.
Let’s start with 19.0
This is absolutely same value as the number 19
Furthermore let’s write 19.00
This is also same value as the number 19
Lastly;
19.000
This is same value as the number 19
Answer:
25
Step-by-step explanation:
From the given information;
Numbers of posters that can be printed in an hour = no of impression/hour × no of plate utilized in each impression.
= 1000x
Thus, the required number of hours it will take can be computed as:

cost per hour = 125
If each plate costs $20 to make, then the total number of plate will equal to 40x
∴
The total cost can be computed as:


At C'(x) = 0




x = 25


where; x = 25

C''(x) = 1.6
Thus, at x = 25, C'' > 0
As such, to minimize the cost, the printer needs to make 25 metal plates.
Answer:
equation involves an equal sign, ' = '
while expression does not have an equal sign.
for example:
an equation is 5x² × 3 = y
an expression is 2xy + 3
