a) You put the scientific notation in expanded form, 671,000,000. From there just divide it by 60. 11,183,333.333 miles per minute.
b) Take the miles/minute rate and multiply it by 8.3; 92821666.6667 miles per 8.3 minutes.
Hope this helps :)
Answer:
0.61
Step-by-step explanation:
Pr (female) = total number of females(n')/Total number of students(n)
Where P(female) = probability of selectinga female
Pr(female) = n'/n................. Equation 1
Given: n = 44 students, n' = 15+12 = 27 females
Substitute into equation 1
Pr(female) = 27/44
Pr(female) = 0.61.
Hence the probability of selecting a female is 0.61
Answer:
I think it would be 5 and 5 of each solution
Answer:
x ≤ 2
Step-by-step explanation:
2 red rose cost $ 18
x flowers cost $ 11x
"At most " means ≤.
11x + 18 ≤ 40
11x ≤ 40 - 18
11x ≤ 22
x ≤ 2
top left: speed = 2.7 miles per hour = 2.7 MPH
top right: speed = 0 miles per hour = 0 MPH
bottom left: speed = 4 miles per hour = 4 mi/h
bottom right: speed = 2 miles per hour = 2 mi/h
and so, the fastest is bottom left. And pay attention in class! i'm in highschool and Iearned this in 6th grade!
Step-by-step explanation:
key: speed= distance/time
distance= speedxtime
time=distance/speed
top left: 8/3= 2.66667 MPH= 2.7 MPH
top right: 0/8= 0 MPH= 0 MPH
bottom left: 8/2= 4 MPH= 4 MPH
bottom right: 8/4= 2 MPH= 2 MPH
