Answer:
Step-by-step explanation:
a/(b+c) < 2a/(a+b+c)
b/(a+c) < 2b/(a+b+c)
c/(a+b) <2c/ (a+b+c)
so a/(b+c)+b/(a+c)+c/(a+b) <2(a+b+c)/(a+b+c)=2
Answer:
8/15
Step-by-step explanation:
you first want to change your whole number, 4, into a fraction so all you have to do is add a 1 in the denominator so it will be 4/1
then you multiply across
2/15 * 4/1
you first multiply 2 and 4 and your answer will be 8 which is the numerator
then multiply 15 and 1 which is 15, the denominator
then you get
8/15

Answer:
$4
Step-by-step explanation:
Trey sold his $80 hockey stick for 25% less. This means that he received 75% of the $80. Convert the percentage to a decimal, so it will be .75. Multiple .75 by $80 and you will get the final answer which is $60.
Brandon sold his $80 hockey stick for 30% less. This means that he received 70% of the $80. Convert the percentage to a decimal, so it will be .70. Multiple .70 by $80 and you will get the final answer which is $56.
Trey received $4 more for his hockey stick.
Determine whether the value is from a discrete or continuous data set. Number of coins in a jar is 78 number of coins in a jar is 78
Answer: Number of coins in a jar is from a discrete data set. Because the given variable is countable in a finite amount of time.
If a variable can take on any value between two specified values, it is called a continuous variable; otherwise, it is called a discrete variable.
