Answer:
1) 4 days 2) P30 3) P125 4) 6 adult 5) smallest number : 57.77 largest number = 72.22
Step-by-step explanation:
1)
6 litres --> 3 days
1 litres --> 1/2 days
8 litres --> 1/2 * 8 = 4 days
2)
3 ball pens --> P18
1 ball pens --> P6
5 ball pens --> P30
3)
12 pencils --> P60
1 pencils --> P5
25 pencils --> P125
4)
7 children --> 2 adults
1 chldren --> 2/7 adults
21 children --> 2/7 * 21 = 6 adult
5) 4:5
4x+5x=130
x = 130/9
4x = 57.77
5x = 72.222
Answer:
35 is its width and 63 is its length.
Step-by-step explanation:
7 x 5 = 35 and 98 - 35 equals 63 which is the length.
B.!!!!!! !!!!
that’s the answer
The impulse delivered to the baseball is 140kgm/s.
Option B) 140 kg • meters per second is the correct answer.
<h3>What is Impulse?</h3>
An impulse is simply a concept that involves the change in the momentum of an object when force is introduced for a period of time.
It is expressed as;
ΔP or Change in Momentum = F × t
Where F is force applied and t is the elapsed time.
Given that;
- Mass of baseball m = 0.25kg
- Time of contact t = 0.0075s
- Force exerted F = 18500N = 18500kgm/s²
We substitute our given values into the expression above to determine the impulse.
ΔP = F × t
ΔP = 18500kgm/s² × 0.0075s
ΔP = 18500kgm/s² × 0.0075s
ΔP = 138.75kgm/s = 140kgm/s
Therefore, the impulse delivered to the baseball is 140kgm/s.
Option B) 140 kg • meters per second is the correct answer.

Answer:
0.3024
Step-by-step explanation:
Given the following :
Probability of breaking pinata on first hit = 0.58;
P(first hit break) = 0.58
P(does not break on first hit) = 1 - p(first hit break) = 1 - 0.58 = 0.42
P(2nd hit break) = p(first hit break) + 0.14 = 0.58 + 0.14 = 0.72
Hence, Calculate the probability that Amanda does not break the piñata on the first hit and does break the piñata on the second hit
P(does not break on first hit) * p(2nd hit break)
0.42 * 0.72 = 0.3024
