Answer:
The truck have travelled 345.5 inches after 5 rotations of the tires
Step-by-step explanation:
Given:
Diameter of the tyre= 22 inches
Number of rotations= 5
To find:
Distance travelled after 5 rotations=?
Solution:
We have given with diameter,
So let radius be r
r= 

r=11 inches
The distance covered by one rotation is given by circumference
Circumference =
Substituting the values, we get
Circumference =
Circumference =
Circumference =
Circumference =
Circumference = 69.11
Now for 5 rotation,
Distance travelled = 
Distance travelled = 
Distance travelled = 
The truck will travel 345.5 inches.

Step-by-step explanation:
Using the given information, the width of the river is 505.96 m
<h3>Bearing and Distances</h3>
From the question, we are to determine the width of the river
Consider the given diagram,
Let F be the first position of the biker
S be the second position
and C be the position of the church
First, we will determine the distance covered from F to S
Speed = 160m/min
Time = 4 minutes
Using the formula,
Distance = Speed × Time
Distance covered = 160 × 4
Distance covered = 640 m
That is, /FS/ = 640 m
Now, consider ΔFSC
∠F = 90° - 70° = 20°
∠S = 90° + 56° = 146°
and ∠C = 180° - 20° - 146° = 14°
By the Law of Sines

∴ 

/FC/ = 1479.33 m
Now,
By SOH CAH TOA

NOTE: d is the width of the river
∴ d = /FC/ × cos70°
d = 1479.33 × cos70°
d = 505.96 m
Hence, the width of the river is 505.96 m

Answer:
3
Step-by-step explanation:
We can use the slope formula:

Let's let (11,8) be x₁ and y₁ and let's let (17,26) be x₂ and y₂. So:

Subtract:

So, our slope is 3.
And we're done!
