The manager of a store marks up all
items by 10%. if x is the original price,
which expression represents the new
price with the markup? select all that
apply.

1.1x

x + 0.1x

Step-by-step explanation:

The manager of a store marks up all  items by 10%.

So, if the original price of any item is x, then increase for markup is 10% of x i.e. .

Hence, the expression that represents the new price with the markup is (x + 0.1x) = 1.1x.

Therefore, options C and D i.e. 1.1x and (x + 0.1x) both are the required expression for the new price. (Answer)

answer: 180

step-by-step explanation:

12-2=10

20-2=18

18x10=180

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
