Answer:
128mm
Step-by-step explanation:
Given

Determine the length of the openings of the pipe
To do this, we simply add 40mm to the length of the pipe.
This gives:


<em>Hence, the opening must be 128mm</em>
According to PEMDAS, division goes before subtraction. So, we divide 15 by 3, which equals 5. That leaves us with 12-5-3. Now, we subtract 5 from 12 = 7. Finally, 7 - 3 = 4, therefore, the answer is 4.
Step-by-step explanation:
remember the domain is the interval or set of valid input (x) values. the range is the interval or set of the valid result (y) values.
so, the given domain tells us the interval to look at.
what are the functional values of the function between 0 and 50 ?
since the function is continuous (there are no gaps) in this interval, we can safely assume that all values between f(0) and f(50) are valid y values.
f(0) = 4×0 + 5 = 5
f(50) = 4×50 + 5 = 205
so, the range is 5 <= y <= 205
