56.52 ÷ pi(3.14) = 18
18 ÷ 2 =9
A = pi(3.14)r^2
A = 3.14 × 9^2
A = 3.14 × 81
A = 254.34in^2
Answer:
7.5 hours
Step-by-step explanation:
We can model an equation for this problem.
We can write:

Where
F is the final temperature (15 degrees we need)
m is the rate of temperature change (2 degrees per hour)
and
t is the time, in hours, it will take (we need to find this)
It is given,
F = 15
m = 2
So, t would be:
F = mt
15 = 2t
t = 15/2 = 7.5
So it will take 7.5 hours
Step-by-step explanation:
integers are whole numbers.
3/5 is a rational number because it represents a ratio of two integers (and denominator ≠0).
4x - 5y = 40
4x = 40 + 5y
x = 10 + 5/4y
The x intercept is 10.
Answer: I think it is greater than
Step-by-step explanation:
Because positive - negative = positive
