Answer:
$0.06 per square inch
Step-by-step explanation:
The question should be:
<em>"If tile costs $8.50 per square foot, how much does it cost per square inch?"</em>
<em />
To solve this, we basically need a conversion from feet to inches. BUT 2 times, since we are talking about "square feet" and "square inches".
We know 1 feet = 12 inches
Also, since we are going from square feet to square inches [big to small], we have to divide TWICE.
Thus, we will have:

We are dividing 8.5 (the cost) by 12, 2 times since we want square feet in square inches. The answer is:

So, tile costs $0.06 per square inch
25 students.....10 of which passed...
percentage of students that passed : 10/25 = 0.4 = 40% <==
Since 5x is equal to y.we can write 5x instead of y in the equation.and then solve the equation
Answer:
b = 60
Step-by-step explanation:
The sum of the angles of a triangle are 180
80+40+b = 180
Combine like terms
120+b =180
Subtract 120 from each side
b = 180-120
b = 60
