Answer:

The correct answer is C

Step-by-step explanation:

The first composition performed by student is rotation of 90° clockwise on A to get A'' then A' can't be obtained either by reflecting A'' across x-axis or y-axis.

But on rotating A by 90° counterclockwise to get A'' and reflecting this A'' across x-axis we get the required composition.

So, student need to rotate the figure 90° anticlockwise instead of 90° clockwise

So, The right answer is C.

F) The marked price of a radio is 25 % above the selling price and the cost pr

Ostrovityanka [42]

Answer:

See explanation below.

Step-by-step explanation:

Let's say, $x$ represents the sale price of radio.

Then the marked price of the radio is $1.25x$

The cost price of the radio is $(1.25x)(0.70)$

The discount is simply 25% because the radio is being sold at 25% less then the marked price.

The gain percent is given as:

$\frac{x-1.25x\times \:0.70}{x}\times 100\\\\=12.5\%$

The radio is being sold at 12.5% gain.

Best Regards!

The length of a rectangular floor is 2 feet more than the width. The area of the floor is 168 square feet. Kim wants to use a ru

defon

The area of the rectangular is expressed in the formula A = l*w where l is the length and w is the width. from the first satement, l = 2 + w; then A = (2+w)*w = 2w + w^2. If A is equal to 168, then w should be equal to 12 feet and l is equal to 14 feet. Hence the width due to the border limits is 12- 2*2 equal to 8 feet
