Answer:
3.9 mi/h
Step-by-step explanation:
If the boy is rowing perpendicular to the current, the two vectors form a right triangle.
AB represents the downstream current, BC is the speed across the river, and AC is the ground speed of the boat
AC^2 = 2.4^2 + 3.1^2 =5.76 + 9.61 = 15.37
AC = sqrt(15.37) = 3.9 mi/h
The boat's speed over the ground is 3.9 mi/h.
Answer:
-5/9 ≥ 5k
Step-by-step explanation:
no less than means greater than or equal to because -5/9 is the lowest it can go (nothing less than), meaning that number or higher. 5 times a number k is just 5 times k, which is 5k to the inequality is
-5/9 ≥ 5k
<h3>
Answer: 2/5</h3>
This is because there are 20 women out of 50 people total (30+20 = 50).
So 20/50 = 2/5
This converts to the decimal form 0.4 and the percentage form 40%
