2. the ans is C because 3 sides in option C keep the same ratio as the 3            sides of triangle NOP: 7.5/5=1.5, 10.5/7=1.5 and 13.5/9=1.5

3. the ans is D  
    just see from the point Q(16,4), after the first dilation, the x-coordinate of        Q=16*0.25=4, then by subtracting 4 from the x-coordinate of point T (i.e.        -2-4=-6), then you can see only option D has the x-coordinate (x-6), so it        shows that it is the ans

4. i dont know about this.. sorry :(

Kamila buys a dress for £30 in a sale. It was advertised "25%off". Kamila says"25% of £30 is £7.50 so i saved £7.50". Explain wh
sveta [45]

Answer:

She was wrong in her analysis because the sales discount of 25% is the discount on the original cost of the dress and not the purchasing cost of the dress as explained below:

Step-by-step explanation:

From the question:

Purchasing cost price of the dress = £30

However, this cost (£30) was after a 25% Sales Discount        

It, therefore, implies that £30 is equal to 75% of the cost price

75% of the original cost price  = £30

100% of the original cost price = (30 x100%)/75%

   Original cost price                 = £40

Therefore the 25% discount / savings on the cost

                                                     = £ (40-30)

                                                      = £10    

She saved £10 by buying the dress at £30 instead of the original cost of £40

The probability of picking two black marbles from a box at random without replacement is 10/91 .
sasho [114]
The probability of the 2 events are multiplied to get the result 10/91

so we have the relation 5/14 *  x  = 10/91

where x is the probability of drawing the second black

so x =  10/91 * 14/5 =  4/13   answer
