Its very easy. Whats the math problem ill help you out.
Answer:
The coordinates of a point are called an ordered pair because the order of the two numbers is important. The first number in the ordered pair is the x coordinate. It describes the number of units to the left or right of the origin. The second number in the ordered pair is the y coordinate.
Step-by-step explanation:
#22 you just figure out the common denominator, then figure out from there and #24 i dont understand
V - the crew rowing rate,
u - rate of the current.
Downstream: v + u = 13.5/1.5 = 9 mph
Upstream : v - u = 13.5/4.5 = 3 mph
u = 9 - v
v - ( 9 - v ) = 3
v - 9 + v = 3
2 v = 12
v = 6 mph, u = 9 - 6 = 3 mph
Answer: the crew`s rowing rate is 6 mph and the rate of the current is 3 mph.
Answer:
C) 153.9 in²
Step-by-step explanation:
14 ÷ 2 = 7
π = 3.14
3.14×7×7 = 153.9 in²
hope this helps!
