Answer:
Greatest common factor (GCF) of 80 and 100 is 20. GCF(80,100) = 20. We will now calculate the prime factors of 80 and 100, than find the greatest common factor (greatest common divisor (GCD) of the numbers by matching the biggest common factor of 80 and 100.
Answer:
Step-by-step explanation:
Approximately 4 liters are in a gallon
(c)*(d)=8*30+8*4=8*34,=>
c=8
d=34
a+b>a-b, =>a+b=d, a-b=c; =>
{a+b=34
{a-b=8, =>a=b+8 ;
(b+8)+b=34
2b=34-8
b=13
a=13+8=21
Answer: a=21; b=13; c=8; d=34.
Answer:
The year in which the population of Los Angeles reached 2.6 million is 1965.
Step-by-step explanation:
We are given the approximate population y (in millions) of Los Angeles between 1950 and 2000 is given by:
y = Population(in millions)
We are supposed to find the year in which the population of Los Angeles reached 2.6 million.
Substitute y = 2.6
The real solution is x=14.77≈15
We are given that 0 corresponds to 1950.
So, 15 corresponds to 1965
Hence the year in which the population of Los Angeles reached 2.6 million is 1965.
