Answer:
12:00 am midnight
Step-by-step explanation:
Given;
I can read a 336-page book in 6 hours.
My rate r1 = 336/6 pages per hour = 56 pages per hour
Jayne can read a 144-page book in 3 hours.
Jayne rate r2 = 144/3 = 48 pages per hour
If I start reading a 5000-page book at noon and Jayne starts reading the same book at 10 AM
Taking 10 am as the reference time.
Let x represent the time from 10 am at which they would both be on the same page.
For me;
Since i started by noon; 2 hours after 10 am
Time t1 = x-2
For Jayne;
She started by 10 am
Time t2 = x
For them to be on the same page they must have read the same number of pages;
Number of pages read = rate × time
r1(t1) = r2(t2)
Substituting the values;
56(x-2) = 48(x)
56x - 112 = 48x
x(56-48) = 112
x = 112/(56-48)
x = 14 hours
Since 10 am is the reference, the time would be;
=10 am + x = 10 am + 14 hours
= 24:00
= 12:00 am midnight
Answer: The percentage is almost 2%
Step-by-step explanation:
Around 50% of live births in the United States are male. The interpretation of this could be 49% or 51% that is 50 plus or minus 1 percent are Male
the remainder are designated female. That is Female = 49% or 51% too.
If many individuals do not fit neatly into either Male or female.
Then the current estimate of the percentage of such births will be around:
+1 - (-1) = 2%
The percentage is almost 2%
Answer:
Step-by-step explanation:
So we just want to get y by itself
2x - 4y = 8
4y = 2x - 8
y = (2/4)x - 2
y = (1/2)x - 2
In this form the y intercept and slope are easy to see. the slope is m and y intercept is b.
slope = 1/2
y intercept = -2
the answer your'e looking for is A
Answer :
There are two cases in this problem :
1). When the ion is positively charged :
Now, the ion and the substance both are positively charged hence when brought together will repel each other because equal charged particles repel each other.
2). When the ion is negatively charged
Now, the substance is positively charged and the ion is negatively charged so both will attract each other because the particles with opposite charges attract each other.
