Answer:its easy it the first one you had posted
Step-by-step explanation:
Just divide.
31 / 40 = .775
31/40 as a decimal is .775.
Area = 50.27 ft squared
area of circle = πr^2
a = π(4^2)
a = π16
a = 50.27
π = about 3.14159
3.14159(16) = 50.26544 --> 50.27
Answer:
c
Step-by-step explanation:
To solve this question, we want to get t by itself, on one side. To do that, the first step is the get all terms with 't' on one side and all the constants (numbers) on the other side.
4t + 2 = 7 t - 7
Since the left side has a greater number of t, let's move all of the terms with t there.
4t - 4t + 2 = 7t - 4t - 7
2 = 3t - 7
Now we move the numbers
2 + 7 = 3t - 7 + 7
3t = 9
Now we get t by itself.
3/3t = 9/3
t = 3
