Mentally, they are numbers in which you can do mental math with since they are whole numbers
Start by identifying any factor of 50 and then rewriting 50 to include that one factor and another:
50 = 5 * 10 5 is prime, but 10 is not. Thus, factor 10:
50 = 5 * 5 * 2 This is 50 as a product of its prime factors 5, 5 and 2.
Answer:
11
Step-by-step explanation:
This is a difference of squares and therefore can be written as (76-1)(76+1)=(75)(77).
So lets look at the factors....
75=3(25)=3(5)(5)
77=7(11)
The biggest prime factor is therefore 11.
Identities used:
Difference of squares a^2-b^2=(a-b)(a+b)
The cost per day is $65 per day, the total cost for 8days will be:
8×65
=520
suppose that E is the number of miles she can drive without exceeding $600.
Thus
0.24×E+520=600
hence solving for E we get
0.24E=600-520
0.24E=80
hence
E=80/0.24
E=333.3333
E~333
