Given:

Toilet rolls com in packs of 4 and 9.

4-pack is priced at £2.04.

9-pack is priced at £4.68.

To find:

The pack that has better value by calculating the price per roll.

Solution:

We have, the 4-pack is priced at £2.04.

So, the price per roll for this pack is:

\dfrac{2.04}{4}=0.51

In the pack of 4 rolls the price per roll is £0.51.

It is given that, the 9-pack is priced at £4.68.

So, the price per roll for this pack is:

\dfrac{4.68}{9}=0.52

In the pack of 9 rolls the price per roll is £0.52.

Since the price per roll in the pack of 4 rolls is less that the price per roll in the pack of 9 rolls because 0.51 < 0.52, therefore the pack of 4 rolls has better value.

What is median of 3 7 5 2 4 2 53 6 9 7 7 3 5 2 7 3 2 2 7
ludmilkaskok [199]

Answer:

5

Step-by-step explanation:

To find the median number of

3 7 5 2 4 2 53 6 9 7 7 3 5 2 7 3 2 2 7

Number them from least to greatest

2 2 2 2 3 3 3 4 5 5 6 7 7 7 7 7 9 53

Since this isn't an even numbered set, all we do is cancel each number out equally on both sides until only one number which should be in the middle is left. This gives you an answer of 5

Hope this helps!

Given that f(x) = ax – 5 and f(4) = 15, determine the value of a.
agasfer [191]

Given that f(x) = ax – 5 and f(4) = 15, then the value of a is 5

The given function is:

f(x)  =  ax  -  5

If f(4)  =  15, then x = 4

Substitute x = 4 into f(x) = ax - 5

f(4)  =  a(4)  -  5

15   =  4a   -  5

Solve for a by adding 5 to both sides

15  +  5  =  4a  -  5  +  5

20    =  4a

Divide both sides by 4

4a/4   =  20/4

a    =  5

Given that f(x) = ax – 5 and f(4) = 15, then the value of a is 5

A kite has angle measures of 7x, 65, 85, and 105. Find the value of x. What are the measures of the angles that are congruent?
Gnesinka [82]

Answer:

  • x = 15
  • 105

Step-by-step explanation:

A kite is a quadrilateral, so the sum of its angle measures is 360°.

  7x + 65 + 85 + 105 = 360

  7x = 105 . . . . . . . . . . . . . . . . . subtract 255. This answers the second part of the question: the missing angle is 105°, so is congruent to the 105° angle given.

  105/7 = x = 15 . . . . . . . . . . . . divide by the coefficient of x
