Answer:
Step-by-step explanation:
To find the median, arrange the data in ascending order
10,20,30,40,50,60,70,80,90
Number of data = 9 . It is a odd number
So, median will be the (n+1)/2 th term

Median = 50
Answer:
t=7,t=0
Step-by-step explanation:
2t^2-14t+3=3
Subtract 3 from both sides
2t^2 - 14t +3 - 3 = 3-3
Simpilfy
2t^2 -14t = 0
Answer:
Rosa ran
of the total distance between her house and her school.
Step-by-step explanation:
Distance between Rosa's house and her school =
miles ≈ 4.5 miles
She ran distance = 3 miles
Therefore, fraction of the total distance between her house and school she run = 
= 
= 
= 
Therefore, Rosa ran
of the total distance between her house and her school.
0.20km is the answer.
Explanation: 1ft = 30.48cm
The GCF is 
Explanation:
The GCF or greatest common factor is the factorization of two or more numbers to determine the greatest number that they have common.
The given terms are
and 
To determine the gcf of these two terms, let us find the greatest number that they have in common.
Comparing the powers of m from both the terms, we have,

Similarly, comparing the powers of n from both the terms, we have,

Also, comparing the powers of p from both the terms, we have,

Thus, the GCF of the terms
and
is
