Answer : The different is, find BC - AC and find AC + CB, find AB and find CA + BC are same.
Step-by-step explanation :
As see that, AB is a line segment in which point C is represented in between the line.
As we are given that:
AC = 3
CB = 7
So,
AC + CB = 3 + 7 = 10
Similarly,
CA + BC = 3 + 7 = 10
Similarly,
AB = AC + CB = 3 + 7 = 10
But,
BC - AC = 7 - 3 = 4
From this we conclude that, find AC + CB, find AB and find CA + BC are same things while find BC - AC is a different thing.
Hence, the different is, find BC - AC and find AC + CB, find AB and find CA + BC are same.
Answer:
Devon earned $86.45
Step-by-step explanation:
first, we know that the final price is 960.51 and we know that devon only gets 9% of that.
so we just need to multiply the final price by the percentage
960.51 x 9% = 86.445
then we round up to 86.45
Answer:
51 milligrams
Step-by-step explanation:
Exponential growth or decay can be modeled by the equation ...
y = a·b^(x/c)
where 'a' is the initial value, 'b' is the "growth factor", and 'c' is the time period over which that growth factor applies. The time period units for 'c' and x need to be the same.
In this problem, we're told the initial value is a = 190 mg, and the value decays to 95 mg in 19 hours. This tells us the "growth factor" is ...
b = 95/190 = 1/2
c = 19 hours
Then, for x in hours the remaining amount can be modeled by ...
y = 190·(1/2)^(x/19)
__
After 36 hours, we have x=36, so the remaining amount is ...
y = 190·(1/2)^(36/19) ≈ 51.095 . . . . milligrams
About 51 mg will remain after 36 hours.

Answer: There are 7 students who want French only.
Step-by-step explanation:
Since we have given that
Number of students is planning schedules = 30
Number of students who want to take French = 16
Number of students who want to take Spanish = 16
Number of students want to take Latin = 11
Number of students who take both French and latin = 5-3 =2
Number of students who take French and Latin and Spanish as well = 3
Number of students who only want Latin = 5
Number of students who only want spanish = 8
According to venn diagram, we get that
So, it becomes,
Similarly,
Similarly,
Hence, there are 7 students who want French only.
