Answer:
1 mile = 1,609 meters is the key to converting the rates of the two swimmers
Step-by-step explanation:
there are 60 seconds in a minute and 60 minutes in an hour
so 1.8 meters/sec x 60 sec/min x 60 min/hr = 6480 meters/hr
now we convert meters to miles
6480 meters/1 hr x 1 mile/1609 meters = roughly 4 miles/hr (4.027)
or we can convert the other rate to meters/sec
2.5 mi/hr x 1hr/60 min x 1min/60 sec = 0.00069444 mi/sec
then convert miles to meters
0.00069444 mi/sec x 1609meters/ 1mi = roughly 1.1 meters/sec (1.117)
A = 1/4 * (pi) * d^2
A = 1/4 * (pi) * 8^2
A = 1/4 * (pi) * 64
A = 1/4(64) * (pi)
A = 64/4 * (pi)
A = 16 (pi) in^2
Your answer is 16 pi in^2

Answer:What’s the question-
Step-by-step explanation:9-4 and greater than -19? Oh 5 because 9-4=5 but it’s greater than -19 because -19 is a negative number.
3/1, 2/, 6/, 4/1, hope I helped!
Since the number is a fraction make a number line using fractions. The inequality sign includes being equal to, so add a solid dot on -5/2 and since x is less than that, draw an arrow pointing to the left.
See attached drawing.
For interval notation since x can be any number less than or equal to -5/2 it would be written as (-∞, -5/2]
