Answer:
Step-by-step explanation:
Given that:
Distance to friends's house = 1.8 miles
Time taken = 12 minutes
Since the rate is constant :
The rate Is related to distance and time :
The two variable equation which represents the equation is :
Speed = Distance / time
To evaluate a function at a given input, you have to substitute every occurrence of the variable with that particular value.
So, for the first function, you have

The name of the variable is obviously irrelelvant, so the same goes for the second function:

An acute angle has a smaller measure than an obtuse angle
Answer:
Step-by-step explanation:
turn the 4/3 into a decimal.=1.33
multiply 1.33*3.14=4.1762
i cant see the rest is it r³?

Hello!</h2>
The answer is:
The correct option is:
D. 40 feet.
<h2>
Why?</h2>
To solve the problem and calculate the width of the river, we need to assume that the distance from A to B and the angle formed between that distance and the distance from A to the other point (C) is equal to 90°, meaning that we are working with a right triangle, also, we need to use the given angle which is equal to 34°. So, to solve the problem we can use the following trigonometric relation:

Where,
alpha is the given angle, 34°
Adjacent is the distance from A to B, which is equal to 60 feet.
Opposite is the distance from A to C which is also equal to the width of the river.
So, substituting and calculating we have:


Hence, we have that the correct option is:
D. 40 feet.
Have a nice day!
