Answer:
7.1
Step-by-step explanation:
write pythagorean theorem 
+ = 
2
= 100
divide 2 both side:
= 50
= 
=
= 7.07106781
round to nearest tenth:
= 7.1
Answer: 11.33
Step-by-step explanation: First you must multiply 42 x 500, which gets you 21,000. Then you divide 238,000 by 21,000 to get 11.33
Answer:
The time it takes for the stone to reach the ground is 3.94 s. This answer is correct.
Step-by-step explanation:
I believe there's a mistake in the equation shown, the acceleration (number that multiplies t²) should be negative, since the stone is falling, therefore I'll answer assuming it's -16 instead of 16, otherwise there would be no real solution to the equation.
In order to calculate how long it'll take for the stone to hit the ground we must make f(t) = 0 and find the time "t" that makes the equation valid, so we have:
f(t) = -16t² + 248 = 0
-16t² = -248
t² = -248/(-16) = 15.5
t = sqrt(15.5) = 3.94
Answer:
r/n
22.91%
33.33%
Step-by-step explanation:
To calculate the experimental probability, we must divide the number of times the event occurred by the total number of events, that is:
r / n
r = 11, n = 48
11/48 = 0.2291
In other words, the experimental probability is 22.91%
for the theoretical probability it would be the quantity that there is of that object among the total quantity of objects, in this case it would be:
1/3 = 0.3333
that is, the probability is 33.33%
