A dress is offered at £105 in a 30% sale.
How much does it normally cost?

the answer of the question is $36

£150

Step-by-step explanation:

£105 is the already reduced price. and it is reduced by 30%.

that means that price is 100-30 = 70% of the original price

so, how to get the 100% out of the 70% ?

well, in the same way we do it also in the other direction.

basically, figure out 1%, and then go for how many % we need.

so, we need to divide 105 by 70 (to get 1%) and then multiply the result by 100 (to get 100% out of the 1%).

price = 105/70 × 100 = 105 × 100 / 70 = 105 × 10 / 7 =

= 15 × 10 = £150

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.
