<h2>15</h2>
Step-by-step explanation:
The formula of a slope <em>m </em>:
From the graph we have the points (0.2, 3) and (0.4, 6).
Substitute:
Answer:
y=4x+8
Step-by-step explanation:
y=mx+b where m=slope and b=y-intercept
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.
If three hens lay 3 eggs any 3 days. The number of days that 3 Hens give in 9 eggs is: 9days.
<h3>
Number of days that three hens lay 9 eggs</h3>
Given:
3 hens lay 3 eggs in 3 days
First step is to determine the number of egg one hen lay in 3 days
1 hen in 3 days lays 3/3
1 hen in 3 days lays=1 egg
Second step is to determine the number of egg 3 hens lay 1 day
1 hen in 1 day lays 1/3 egg
3 hens in 1day lay=(1×3)/3
3 hens in 1day lay=1 egg
Third step is to determine the number of eggs 3 hens lay in 9 days
3 hens in 9 days lay=(1×9)
3 hens in 9 days lay=9 eggs
Therefore assuming three hens lay 3 eggs any 3 days. The number of days that 3 Hens give in 9 eggs is: 9days.
