Answer:

4( \sqrt[5]{ {x}^{2} y} ) + 3( \sqrt[5]{ {x}^{2}y } ) \\

factorise out the 5th root of x²y :

=  \sqrt[5]{ {x}^{2}y } (4 + 3) \\  = 7( \sqrt[5]{ {x}^{2} y} )

The speed is the change in position divided by the time.

There are four intervals where the speed is uniform:

1) from 0 to 0,5 hours
2) from 0,5 hours to 3 hours
3) from 3 to 4 hours
4) from 4 to 7 hours

We are asked to say the average speed during the interval in which J. is traveling the fastest.

That is where the is more inclined, and that happen in the last interval. There the speed is tha change in position / the time =
(200 -0)miles/3hours = 67 mph.

If you are not sure that this is the fastest speed, you can calculate the speed in the other intervals in the same way and compare.

What is the total number of pages in the e-book
Dafna1 [17]

Answer:

Step-by-step explanation:

If 75 percent is 180 pages, we need to find the amount of pages the remaining 25 percent of the book has and add that to 180 pages because 75+25 = 100. 75/3 is equal to 25.

75:180 =

25:60.

By dividing the ratio, we found out that if Logan read 25 percent of his book, he would have read 60 pages.

180 + 60 = 240.

The total number of pages is 240

Which of the points listed below is not on the line with equation 7y+2=3x-5
kicyunya [14]

Answer: Second option.

Step-by-step explanation:

Given the folllowing Linear Equation:

7y+2=3x-5

You need to substitute the coordinates of each point given in the options into the equation and then evaluate.

1) Substituting  (2, -\frac{1}{7}) into the equation, you get:

7(-\frac{1}{7})+2=3(2)-5\\\\-1+2=6-5\\\\1=1\ (TRUE)

2) Substituting the point (3, -\frac{3}{7}). you get:

7(-\frac{3}{7})+2=3(3)-5\\\\-3+2=9-5\\\\-1=4\ (FALSE)

3) Apply the same procedure using the point (1, -\frac{4}{7}):

 7(-\frac{4}{7})+2=3(1)-5\\\\-4+2=3-5\\\\-2=-2\ (TRUE)

4)  Apply the same procedure using the point (-1, -\frac{10}{7})

 7(-\frac{10}{7})+2=3(-1)-5\\\\-10+2=-3-5\\\\-8=-8\ (TRUE)

5) Substituting  (0,-1) into the equation:

 7(-1)+2=3(0)-5\\\\-7+2=-0-5\\\\-5=-5\ (TRUE)

Therefore, the point (3, -\frac{3}{7})  is not on the given line.

Answer:

410 student and 436 adult tickets

Step-by-step explanation:

x is the number of student tickets and y is the number of adult tickets sold. we now that a total of 846 tickets were sold so x+y=846=>x=846-y. we also now that their worth was 3 846usd so 3*x+6*y=3846. we substitute x and are left with the following equation:3x+6*(846-x)=3846

5076-3x=3846

3x=1230

x=410

=>y=846-410=436
