A student can pitch a fast ball at 65 miles per hour. Convert this
AnnyKZ [126]

Answer:

31.77 yd/sec

Step-by-step explanation:

<u>Conversions:</u>

  • 1 mile = 1760 yards
  • 1 hour = 3600 seconds

<u>Given:</u>

\sf 65\:miles\:per\:hour=65\:miles/hour=\dfrac{65\:miles}{hour}

Therefore, to convert 65 mph to yards per second:

\implies \sf \dfrac{65\:miles}{hour}=\dfrac{65 \times 1760\:yards}{3600\:seconds}=31.777...\:yd/s

What is m∠HLK? thanks
Katen [24]
The answer is 80°.

If there is a line segment in a triangle which cuts two sides in half or if there is a line segment between two midpoints of a triangle's sides, that line segment must be parallel to the remaining side.

In this case, point L is the midpoint of FH, and point K is the midpoint of HG. So, LK is parallel to FG.

When a line cuts two parallel lines, there are angle pairs which are equal. In the problem above, the line segment FH cuts KL and GF.

The angles KLH and GFH are what we called "Corresponding Angles" and they are equal.

So if HFG is 80°, HLK must be equal to 80°
