The area of a circle is pi times radius^2
So if you use 3.14 x 16, it gives you approximately 50.264
9.9714 x 10^-1
That would be in scientific notation
Answer:
36 mph.
Step-by-step explanation:
Let x be the distance to the town hall.
Trip there:
speed (s) = distance / time
s = x / 1.5 so x = 1-5s
Trip back:
s - 12 = x / 2 so x = 2s - 24
AS they are both = to x:
1.5s = 2s - 24
0.5s = 24
s = 48.
Average speed on the way back = 48-12 = 36 mph.
Answer:
D
Step-by-step explanation:
In the prime factorization of 36 = 2² x 3², the two is used as a factor two times and the three is used as a factor twice. When checking to see if a number is prime or not, you need only divide by those prime numbers that when squared remain less than the given number.
Answer:
they both involve the hypotenuse
