<em>v₂ = 55mph</em>
- Step-by-step explanation:
<em>Hi there ! </em>
<em>Velocity formula</em>
<em>v = distance/time = d/t => d = vₓt</em>
<em>v₁ = v₂ - 11</em>
<em>t₁ = 10h</em>
<em>t₂ = 8h</em>
<em>d = v₁ₓt₁ = (v₂ - 11)t₁ </em>
<em>d = v₂t₂</em>
<em>(v₂ - 11)t₁ = v₂t₂</em>
<em>replace t₁ ; t₂</em>
<em>(v₂ - 11)10 = v₂8</em>
<em>10v₂ - 11ₓ10 = 8v₂</em>
<em>10v₂ - 8v₂ = 110</em>
<em>2v₂ = 110</em>
<em>v₂ = 55 mph</em>
<em>Good luck !</em>
Answer:
I think that it is y=15x+35
Step-by-step explanation:
15*x is how many hours and you have to pay $35 regardless to rent the boat
Answer:
x = -60
Step-by-step explanation:
1/3x=−20
X is 1/3
X times 3 = a full X
Fill it in
X times -20 = -60
Hope this helps :)
Answer:
Step-by-step explanation:
Trigonomos used tangent to solve it.
Let the width of the river is w.
- tangent = opposite leg / adjacent leg
- tan 76° = w / 15
- w = 15 tan 76°
- w = 60.16 m
