bija089 [108]

The pathway is 8.46 yards.

<h3>How to find the length of the pathway?</h3>

To find the length of the pathway, it is required to find how long is the diagonal line from one corner of the herb garden to the opposite corner. As shown in the image attached.

The general formula for this is:

  • d = a√2 or diagonal = side√2

Let's apply this formula:

  • d= 6 √2
  • d= 6 x 1.41
  • d= 8.46 yards

SpyIntel [72]

Answer: Prokhorova is more outstanding.

Step-by-step explanation: To compare scores from different distributions, first standardize it:

z-score = \frac{x-\mu}{\sigma}

where

x is the individual mean you want to compare

μ is the mean of the population

σ is standard deviation

For <u>Gertrud Bacher</u>:

z-score = \frac{129-137}{5}

z-score = -1.6 (s)

The negative sign indicates Bacher's mean is less than the mean

For <u>Yelena Prokhorova</u>:

z-score = \frac{660-600}{30}

z-score = 2 (cm)

The positive sign indicates Prokhorova's mean is more than the mean.

Using z-score table, you determine the percentiles are:

For Bacher: Percentile = 5.5%

For Prokhorova: Percentile = 97.7%

Bacher's percentile means she is above 5.5% of the participants, while Prokhorova is 97.7% above the other competitors, which means Prokhorova have a better performance and deserves more points.

If a car has tires with a radius of 1.5 ft and the tires are spinning at 840 rpm (revolutions per
tamaranim1 [39]

Answer:

89·98 mph

Step-by-step explanation:

First, we get the circumference of the tires:

Circumference = \pi × (radius × 2)

Circumference = 3.142 × (1·5 × 2)

Circumference = 3·142 × 3

Circumference = 9·426 ft

The circumference of the tire is equal to one round.

      1 round = 9·426 ft

840 rounds = ?

We cross multiply to get the length that the tires would cover in a minute

= <u>840 × 9·426</u>

       1

    1 minute = 7917·84 ft

60 minutes = ?

<u>60 × 7917·84</u>

          1

= 475070·4 ft

      5280 feet = 1 mile

475070·4 feet = ?

<u>475070·4 × 1</u>

     5280

475070·4 ÷ 5280 = speed of the car in mph

89·97545

Round this off to 2 decimal places...

= 89·98 mph

hope this helps! =)
