If a car is moving at a speed of 30 miles per hour, how many miles

Mathematics

Ne4ueva [31]3 years ago
4 0

Answer:

90 miles

Step-by-step explanation:

There's more than one way in which to do this.  I have chosen to convert '180 minutes' to '3 hours.'

Since distance = rate times time, we have here:

distance traveled in 180 minutes = (30 mph)(3 hr) = 90 miles

What does AC=?<br> Round your answer to the nearest hundredth. <br><br> Please help
faltersainse [42]

Answer: About 3.06

Step-by-step explanation:

  We can use trigonometry functions to solve for AC. Let the ?, representing AC, be "x" in our mathematical work.

  Since we have the hypotenuse and x is adjacent to the angle given, I am going to use cosine.

      cos(θ) = \frac{adjacent}{hypotenuse }

      cos(40) = \frac{x}{4}

      0.766 ≈ \frac{x}{4}

      3.06 ≈ x

      x ≈ 3.06

A 9 feet tall dragon ice sculpture is melting at a rate of 1.75 feet per hour. Write a linear function that represents this scen
vaieri [72.5K]

Answer:

y = 9 - 1.75x

Step-by-step explanation:

Given

Initial\ Height = 9ft

Rate = 1.75ft per hour

Required:

Determine the linear function

Let y represent the function and x represent the number of hours

The function can be represented with:

y = Initial\ Height- Rate * x

We used minus (-) in the equation because the question indicates that the height of the sculpture reduces.

So, we have:

y = 9 - 1.75 * x

y = 9 - 1.75x

The tax rate is obtained by dividing the amount of the taxes be raised by the cost of the property. Then, multiply the quotient by 100%. The operations are shown below,
                                ($13,750,000) / ($305,000,000) x 100%
The answer is approximately equal to 4.5%. Thus, the answer is letter B.
