Answer:
Step-by-step explanation: 1 foot= 12 inches
so length 5.5 inches= 0.458 feet or 5.5/12
width 4 inches= 0.33 feet or 4/12
area 4x5.5= 1.833 feet or 22/12
Answer:
5/8
Step-by-step explanation:
28x + 4 can be factorised because 28 is a multiple of 4
so it can become
4(7x+1)
35x + 5 can be also factorised because 35 is a multiple of 5
5(7x+1)
we can now rewrite the expression as
6/4(7x+1) * 5(7x+1)/12
we can “eliminate” the two 7x+1 and simplify 6 with 12
so it remains
1/4 * 5/2 = 5/8
Answers:
Lower bound = 41.3
Upper bound = 41.5
===========================================================
Explanation:
49.15 is the smallest f can be while 49.24 is the largest it can be. Well technically we could have something like 49.2499 or 49.24999 and so on. We slowly approach 49.25 but never actually get there
So the variable f is between 49.15 and 49.25 inclusive of the first value but excluding the second value. We can write it as 
For similar reasoning, 
-----------------
If we wanted to subtract those variables and get the smallest result possible, then we need to pick values that are closest together. It might help to set up a number line.
This means we'd go for f = 49.15 and g = 7.85
The lower bound for f-g is f-g = 49.15-7.85 = 41.3
In contrast, the upper bound is when the two variables are spaced as far apart as possible. The upper bound is f-g = 49.25 - 7.75 = 41.5
