Answer:
455m
Step-by-step explanation:
We know that acceleration is acceleration due to gravity, which is 10m/s, and initial speed u=0m/s
Use the motion equation to find distance when t=10:
d=ut+(1/2)at²
d=0t+(1/2)(10)(10²)
d=500m
The distance travelled in the seven seconds following the first three = 500-45=455m
Answer: 6
Step-by-step explanation:
I did it with LCM
-12(x-2) + (24x) = 4x(x-2)
using the quadratic formula, u get 6 and -1
Answer:
The answer is D
Step-by-step explanation:
You divide each by 20
Answer:
80
Step-by-step explanation:
30 = 100
24 = 80
6 x 5 = 30
6 x 4 = 24
5 = 20 because 5 x 8 = 80.
Answer:
Let the digits 0,1,2,3 and 4 represent the birth of a boy, and let digits 5,6,7,8, and 9 represent the birth of a girl. Use a table of random digits. Choose the first 10 digits in the table and record the number of boy and girl births. Continue to choose batches of 10 digits for a total of 100 times, recording the number of boy and girl births. (possibly B)
