I think it’s h=64m because it just makes sense the most
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:
40 nickles
Step-by-step explanation:
Here is the correct question: Earl went to the store and realize he had 7 more Nickles in his pocket then he thought he had; If all the change in earl’s pocket is nickles, he had $2.35 in his pocket, how many more nickles did he think were in his pocket
?
Given: All Nickles in the Earl´s pocket is $2.35.
Remember, 1 Nickles = $.05
∴ Converting the dollar to nickels
$2.35= 
Earl had total 47 nickels in his pocket.
∴ Earl earlier had nickles = 
∵ we know Earl had realized that he had 7 more nickles in his pocket, which means he already had 40 nickles to make $2.35.
