Speed against current = 120 miles / 6 hours = 20 miles / hour
Speed with current = 120 miles /5 hours = 24 miles / hour.

Speed of boat in still water = (20+24)/2 = 22 miles / hour

Answer:

D 28x+40

Step-by-step explanation:

To find the perimeter, we add all the sides

2x+2x+5x+8+4x+10+5x+8+x+2+2x+7x+12 = P

Combine like terms

2x+2x+5x+4x+5x+x+2x+7x+10+8+8+2+12

28x +40

Someone help me asap math 10
Ghella [55]

Answer:

x ≈ 25.4 Km

Step-by-step explanation:

Using the tangent ratio in the right triangle on the right

tan54° = \frac{opposite}{adjacent} = \frac{opp}{17} ( multiply both sides by 17 )

17 × tan54° = opp , thus

opp ≈ 23.4

-------------------------------------------

Using the cosine ratio in the right triangle on the left

cos23° = \frac{adjacent}{hypotenuse} = \frac{23.4}{x} ( multiply both sides by x )

x × cos23° = 23.4 ( divide both sides by cos23° )

x = \frac{23.4}{cos23} ≈ 25. 4 Km ( to the nearest tenth )
