Answer:
it don't
Step-by-step explanation:
Start with the division:
36 ÷ 6 = 6
Then, multiply by 3:
6 x 3 = 18
Square 2:
2² = 4
Next, evaluate the parentheses:
(3 + 5) = 8
Now, we have the expression:
18 + 4 - 8
Perform the addition and subtraction in order:
18 + 4 = 22
22 - 8 = 14
So, the expression simplifies to 14, not 32. It seems there might be an error in the calculation provided for the answer of 32.
The solution to this question is 39.0625.
This is because you will need to multiply the width by height. As this is in square feet it will be irrespective of which two sides we choose.
The calculation that will need to be done is the following :
6.25ft X 6.25ft which will equal 39.0625.
6.25 has three significant digits so rounding 39.0625 off to three significant digits is 39.1 square feet
Answer:
Part 1) The best choice is Plan A
Part 2) The data is
Step-by-step explanation:
Part 1)
Let
y ----> the cost per month
x ----> the number of GB of data per month
we know that
Plan A
Plan B
Find out which plan is the best choice if he uses five to eight GB of data per month
Plan A
For x=5 GB -----> y=5(5)+30=$55
For x=8 GB -----> y=5(8)+30=$70
so
with Plan A the cost is between $55 and $70 -----> average $62.5
Plan B
For x=5 GB -----> y=2(5)+50=$60
For x=8 GB -----> y=2(8)+50=$66
so
with Plan B the cost is between $60 and $66 ----> average $63
therefore
The best choice is Plan A
Part 2) How much data would Irfan need to use for both plans to cost the same?
we have
y=5x+30 ----> equation A
y=2x+50 ----> equation B
Solve the system of equations by elimination
Subtract equation B from equation A
0=5x-2x+30-50
0=3x-20
3x=20
Convert to mixed number
----> for this data the cost is the same in both plans
