PEMDAS = Parentheses, Exponents, Multiplication, Division, Addition, Subtraction
First, subtract the numbers in the parentheses, then multiply by 11.
(12 - 9) = (3)
3 x 11 = 33
19 + 11 - 12^2 ÷ 3(33) - 7
Now, just multiply 33 by 3, and then square 12 (12 x 12).
19 + 11 - 144 ÷ 99 - 7
Now, you can divide 144 by 99, this is an infinite number, so..
144 ÷ 99 = 1.455
19 + 11 - 1.455 - 7
Finally add, then subtract.
30 - 1.455 - 7
28.545 - 7
The final answer is 21.545.
Answer: 15+X=27
Step-by-step explanation: 15+X=27 X Represents How Much More Is Added
The problem does not clearly give us the distance from Buffalo to Chicago, so let this be x (in mile) just so I can show you how the total cost is solved.
The total cost is equal to the sum of the rental fee plus the cost of the additional fee per mile which is equal to 1.50x, and also of the cost of the gasoline which is equal to (x/16)(2.15). Thus, the final answer should be expressed as,
total cost = 29.95 + 1.5x + 2.15x/16
When the distance is available, this should be easily substituted in the equation above.
Answer:
1. V = 130 in³
Step-by-step explanation:
1. You can find the volume of a rectangular prism with this formula:
( l • w )h
(20 • 2)3 1/4
=
130
And then add the label in³
<h3>Answer:</h3>
2. V = 20 ft³
<h3>Step-by-step explanation:</h3>
2. A box is the same as a rectangular prism.
Use the same formula to find the answer.
(4•2 1/2)2
=
20
And then add the label ft³
<h3>Answer:</h3>
3. V = 10 in³
<h3>Step-by-step explanation:</h3>
3. It doesn't matter if the rectangular prism is a "right" one so you can just use the same formula for a rectangular prism.
5/4 = 1 1/4 or 1.25
(1.25 • 2)2
=
10
And then add the label in³
