Susie plans to run 2 miles per day the first week and then increase the daily distance by a half a mile each of the following we
AlekseyPX

Due to length restrictions, we kindly invite to see the explanation below to know the answer with respect to each component of the question concerning linear equations.

<h3>How to determine a linear equation describing the daily distance of a runner</h3>

In this question we need to derive an expression of the <em>daily</em> distance as a function of time. Now we proceed to complete the components:

  1. <em>Linear</em> equations have an <em>independent</em> variable (t - time) and a dependent variable (x - daily distance).
  2. We notice that the daily distance increases linearly in time, then then we have the following pattern:

    t          1            2            3             4            5              6
    x          2          2.5          3           3.5           4             4.5
  3. The equation that represents the n-th term of the sequence is x(n) = 2 + 0.5 · (n - 1).
  4. The week when Susie will run 10 miles per day is:

    10 = 2 + 0.5 · (n - 1)
    8 = 0.5 · (n - 1)
    n - 1 = 16
    n = 17

    Susie will run 10 miles per day in the 17th week.
  5. It is not reasonable to think that pattern will continue indefinitely as it is witnessed in the difficulties experimented by <em>fastest</em> runners in the world to increase their <em>peak</em> speeds.
  6. A marathon has a distance of 26 miles, then we must solve the following equation:

    26 = 2 + 0.5 · (n - 1)
    24 = 0.5 · (n - 1)
    48 = n - 1
    n = 49

    Susie should start her training 49 weeks before the marathon.

Find the area of the sector
sergij07 [2.7K]

Answer:

\boxed {\boxed {\sf a \approx 190.9 \ yd^2}}

Step-by-step explanation:

There are 2 formulas for the area of a sector, but since we are given the central angle in degrees (not radians), we will use this formula:

a= \frac {\theta}{360} \times \pi r^2

Where θ is the central angle and r is the radius.

For this circle, the radius is 9 yards and the central angle is 270 degrees. We can substitute these values into the formula.

a= \frac {270}{360} \times \pi \times (9 \ yd )^2

Solve the fraction.

a=0.75 \times \pi \times (9 \ yd)^2

Solve the exponent.

  • (9 yd)²= 9 yd* 9 yd=81 yd²

a= 0.75 \times \pi \times 81 \ yd^2

Multiply all three numbers together.

a= 190.851753706 \ yd^2

The question asks us to round to the nearest tenth.

  • 190.8<u>5</u>1753706

The 5 in the hundredth place tells us to round the 8 up to a 9.

a \approx 190.9 \ yd^2

The area of the sector is approximately <u>190.9 square yards. </u>

How would I solve for x?​
vaieri [72.5K]

Answer:

x = 65

Step-by-step explanation:

First, we calculate the unknown angle of the left triangle and right triangle:180 - 62 - 50 = 68

Unknown angle for left triangle⬆️

180 - 80 - 53 = 47

Unknown angle for right triangle⬆️

Now we've calculated the two angles for the small triangle in the middle. So, we just have to calculate the top angle of the middle triangle:

180 - 68 - 47 = 65

The angle 65° and angle of x are vertical angle.(both are equal)

So... <u>x= 65°</u>

Please answer these 2 questions for me!!
erma4kov [3.2K]

Answers:

  1. C) 5/14
  2. A) 2/16

===========================================

Explanations:

  1. We have 5+9 = 14 people who don't have a dog. Of this total, 5 have a cat. So that's where 5/14 comes from. We ignore the top row because we know 100% that this person doesn't have a dog (based on what the "given" says).
  2. Focus on the top row. This is because we're given or told that the person completed the hw. We have 2 people who failed the test out of 14+2 = 16 people who did the hw. The fraction 2/16 reduces to 1/8, but it appears your teacher doesn't want you to reduce.
