brad buys a pack of 12 bottles for £9.25
he sells all the bottles for £1 each
work out brads percentage profit

Answers

Answer:

29.87%

Step-by-step explanation:

£9.75 \ 12 = £0.77

This is what he pays for each bottle

He makes £0.23 on each bottle sold

0.23/0.77 x 100 = 29.87

This is the percentage profit.

You can also validate the answer by calculating 29.87% of £0.77 and then add it to the £0.77 and you will see that you get £1

Answer:

Point of intersection of diagonal is: (-4,2)

x-coordinate = -4

y-coordinate = 2

Step-by-step explanation:

The diagonals of parallelogram bisect each other, So we need to find the midpoint of the diagonal to find the point of intersection. The midpoint of both diagonals will be same.

Consider the diagonal BD

We have B (-6,-5) and D (-2,9)

We need to find midpoint of the diagonal BD.

The formula used is: [tex]Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

We have [tex]x_1=-6, y_1=-5, x_2=-2, y_2=9[/tex]

Putting values and finding midpoint

[tex]Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\Midpoint=(\frac{-6+(-2)}{2},\frac{-5+9}{2})\\Midpoint=(\frac{-6-2}{2},\frac{-5+9}{2})\\Midpoint=(\frac{-8}{2},\frac{4}{2})\\Midpoint=(-4,2)[/tex]

So, We get Midpoint(-4,2)

We will get the same midpoint if we find for other diagonal AC.

So, Point of intersection of diagonal is: (-4,2)

x-coordinate = -4

y-coordinate = 2

Answer:

x = 14

Step-by-step explanation:

First put it into slope intercept form

20 = 2x - 8

Move the variable to the left hand side and change its symbol

-2x + 20 = -8

Move the constant to the right hand side and change its symbol

-2x = -8 - 20

Calculate the difference

-2x = -28

Divide both sides of the equation by -2

x = 14

Solution

X = 14

All frictional forces are considered to be negligible. Can the student use the graph and the known data to determine the momentum of the object after the force has been applied?Yes, because the average force exerted on the object can be used with the time interval of 2 s to determine the change in momentum of the object by using p =F t.Yes, because the area bound by the best-fit line and the horizontal axis from 0 s to 2 s can be used to determine the change in momentum of the object.No, because the data is too scattered to determine the average force that is exerted on the object.No, because the student needs to know the direction that the force is applied to the object because the applied force will be in the same direction as the change in momentum of the object. imagine you are picking anumber between 1 and 10 inclusive what is the probability of picking up a nuimber that is even or between 1 and 5 inclusive Zen gardens were the results of intense ______ and manual_____ Which statement best describes the effect of the rhyme in this stanza?
