Answer: 1st table: P=25h No it's not porportional.
2nd table: h=mi/40 Yes it's porportional.
Step-by-step explanation:
1st table:
P equals your total pages read and your h is equal to the amount of hours you read for. So for every h (hour) there are 25 pages read. So in two hours there are 50 read. Since the table doesn't go 50, 75, 100, that means that there was nat a consistant rate so it's not porportional.
2nd table:
Yes this is porportional. The reason is because to find the time the equasion is h=mi/40. the rate of change between the all of the numbers is equal. so for every 40 miles traveled there is 2 of your time.
Answer:
√(x)
Step-by-step explanation:
(1)/(x^-(1/2)) that's 3 goes into -3 leaving 1 and goes into 6 leaving 2
1/2 is same as 2^-1
so therefore we can simplify the above as
x^-(-1/2)
x^(1/2)
and 4^(1/2)
is same as √(4)
so we conclude as
√(x)
Length times width times height, then you get the volume.
Answer:
this is so eigliy to do...............
Step-by-step explanation:
We are here given that a point B is between A and C . Also ,
- Value of AB = 2x
- Value of BC = 3x + 1
- Value of AC = 21 .
And we would like to calculate the length of BC . For figure refer to the attachment. From figure we can see that ,
Substitute the respective values,
Add like terms ,
Subtract 1 on both sides,
Simplify,
Divide both sides by 5,
Now consider ,
Plug in the value of x found above ,
Simplify,
Add,
And we are done !
