Answer:
23. 0.4583 seconds
24. 0.0107 seconds
Step-by-step explanation:
The problem statement tells you how to work it. You need to convert speed from miles per hour to feet (or inches) per second.
90 mi/h = (90·5280 ft)/(3600 s) = 132 ft/s = (132·12 in)/s = 1584 in/s
__
23. The time it takes for the ball to travel 60.5 ft is ...
time = distance/speed
time = (60.5 ft)/(132 ft/s) = 0.4583 s
It takes 458.3 milliseconds to reach home plate.
__
24. time = distance/speed
time = (17 in)/(1584 in/s) = 0.0107 s
The ball is in the strike zone for 10.7 milliseconds.
Answer:
Step-by-step explanation:
Ok then "cracks knuckles" heres an image of the division! hope it helps.
50-10 = 40. 40 divided by 6 = around 6/7. So about 6/7 weeks
Step 1
<u>Find the value of x</u>
we know that
-------> by corresponding angles, because the given lines are parallel
Solve for x
![(x-1)\°=74\°\\x=74+1 \\ x=75\°](https://tex.z-dn.net/?f=%28x-1%29%5C%C2%B0%3D74%5C%C2%B0%5C%5Cx%3D74%2B1%20%5C%5C%20x%3D75%5C%C2%B0)
Step 2
<u>Find the value of y</u>
we know that
![(x-1)+40+(y-2)=180](https://tex.z-dn.net/?f=%28x-1%29%2B40%2B%28y-2%29%3D180)
substitute the value of x and solve for y
![(75-1)+40+(y-2)=180](https://tex.z-dn.net/?f=%2875-1%29%2B40%2B%28y-2%29%3D180)
![74+40-2+y=180](https://tex.z-dn.net/?f=74%2B40-2%2By%3D180)
![112+y=180](https://tex.z-dn.net/?f=112%2By%3D180)
![y=180-112](https://tex.z-dn.net/?f=y%3D180-112)
![y=68\°](https://tex.z-dn.net/?f=y%3D68%5C%C2%B0)
therefore
<u>the answer is the option B</u>
![x=75\°, y=68\°](https://tex.z-dn.net/?f=x%3D75%5C%C2%B0%2C%20y%3D68%5C%C2%B0)
