Wyatt’s eye-level height is 120 ft above sea level, and Shawn’s eye-level height is 270 ft above sea level. How much farther can
brilliants [131]
Using the formula given: d = <span>√(3h/2)

We simply substitute the given values of h into the equation and compare the results.

For Wyatt where h = 120:
d = </span>√(3(120)/2)<span>
d = 13.42 miles

</span><span>For Shawn where h = 270:
d = </span>√(3(270)/2)<span>
d = 20.12 miles
</span>
Since the question asks for how much farther can Shawn see, we subtract the results:

20.12 - 13.42 = 6.7

Therefore, Shawn can see 6.7 miles farther.

bagirrra123 [75]

Answer:

There are 500 students which attends McCord Middle School.

Step-by-step explanation:

Given:

Number of students rode their bike or walked to school =200

percent of students rode their bike or walked to school = 40%

We need to find the total students attend the school.

Solution:

Let the number of total students attending the school be 'x'.

So we can say that;

percent of students rode their bike or walked to school multiplied by total students attending the school is equal to Number of students rode their bike or walked to school.

framing in equation form we get;

\frac{40}{100}x=200\\\\0.4x=200

Dividing both side by 0.4 we get;

\frac{0.4x}{0.4}=\frac{200}{0.4}\\\\x= 500

Hence There are 500 students which attends McCord Middle School.
