With the current 40 miles per hour
Against the current 30 miles per hour
bv means boat velocity with NO current
cv means current velocity
A) bv + cv = 40 mph
B) bv - cv = 30 mph
Adding both equations:
2bv = 70
boat velocity with NO CURRENT = 35 miles per hour
Using equationA
bv + cv = 40
35 + cv = 40
current velocity = 5 miles per hour
Answer:
75%
Step-by-step explanation:
increasing of the circumference is proportional with increasing of the radius
I think the answer is A and C!
An inequality is not equal (duh) so it includes signs like
> more than
< less than
<u><</u> equal to or less than
<u>></u> equal to or more than
so just write something that is true like
5>4
4>3
3<20
x<u>></u>39
