Answer:
54 inches
Step-by-step explanation:
first you're going to want to put four and a half feet into a decimal (4.5) and multiply it by how many inches are in 1 ft ( 12). after that you're going to want to count how many decimal paces there are (2) and move your decimal at the end of 5400 to 54.00. The extra 0s are not needed.
'a' is the correct answer
60 in^2 will be your answer.
To find this I would use the pythagorean theorem which is:
a^2 + b^2 = c^2
Since we already know c = hypotenuse, and a side of the shorter sides we can plug them it like this:
11^2 + b^2 = 12^2
121 + b^2 = 144
b^2 = 23
√23 = 4.79
Round:
B. 4.8 would be your answer!
Answer: 
Step-by-step explanation:
You know that 1 sandwich costs $4.60 and the school bought 47 sandwiches.
Therefore, in order to calculate the total cost of 47 sandwiches, you need to multiply this number of sandwiches bought by the schoole, by the cost of 1 sandwich. Then:

You know that 1 bag of chip costs $1.25 and the school bought 39 bags of chips.
So, in order to calculate the total cost of 39 bags of chips, you must multiply the total number of them bought by the school, by the cost of 1 bag of chips.
Then:
Therefore, the total amount school spent was:
