Work out the percentage change to 2 decimal places when a price of £78.98 is increased to £100

The percentage is 26.6%

Step-by-step explanation:

Here, we want to

work

out the percentage change

To do this, we use the percentage change formula

This is,

percentage change = new value-old value)/old value * 100%

= (100-78.98)/78.98 * 100%

21.02/78.98 * 100% = 26.6%

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
