Answer:
a=5.25
Step-by-step explanation:
Hey there!
First we multiply 3 1/4 x 1 1/2:
3 1/4 = 13/4 and 1 1/2 = 3/2
13 X 3 = 39
4 x 2 = 8
39/8 in simplest form = 4 7/8
Next, multiply 4 7/8 x 9:
4 7/8 = 39/8 and 9 = 9/1 (since it is one whole)
39 x 9 = 351
8 x 1 = 8
351/8 in simplest form is 43 7/8.
Your final answer is 43 7/8.
Hope this helps you.
Have a great day!
OK, so first you would look at 3/5 and you would see that it is basically 3÷5, so then you would get your answer, and all you would need to do after that is transfer the decimal into a percent, good luck!
Answer:
Dimension of room = 18 foot x 18 foot
Step-by-step explanation:
Let the square room is of side a foot,
The cost of re-finishing the hardwood floors is $2.25 per square foot and the cost of purchasing and installing the new baseboards $14.5 per linear foot
Total cost is $1773.
Cost for re-finishing the hardwood floors = Area x 2.25
Area = a²
Cost for re-finishing the hardwood floors = 2.25 a²
Cost of purchasing and installing the new baseboards = Perimeter x 14.5
Perimeter = 4a
Cost of purchasing and installing the new baseboards = 4a x 14.5 = 58 a
Total cost = Cost for re-finishing the hardwood floors + Cost of purchasing and installing the new baseboards
1773 = 2.25 a² + 58a
2.25 a² + 58a - 1773 = 0
a = 18 or a = -43.77(not possible)
Dimension of room = 18 foot x 18 foot
