The red square is the image of the blue square after a SINGLE transformation. Use two or more complete sentences to describe eac

Leni [432]

The transformations which can lead to the red square image of the blue Square are; Translation, Reflection, Rotation.

<h3>What transformations lead to the image?</h3>

Translation is when we slide a figure in any direction. The translation of the shape can be by moving the blue leftward or rightward and the then downward.
Reflection is when we flip a figure over a line. The reflection involves reflect the blue Square over the line; y = x.
Rotation is when we rotate a figure a certain degree around a point. The rotation is by rotating the blue Square over 180⁰.

A pair of shoes which costs Rs 320 was sold at a loss of 5%what was the selling price if it is sold at profit of 20%find the gai

taurus [48]

Answer:

The Sell Price of the shoe at 5% loss is Rs 304.

The Sell Price of the shoe at 20% profit is Rs 384.

The Total Gain Percent is 12.5% when shoes are sold at Rs.360.

Step-by-step explanation:

Given,

Cost Price(C.P.) of shoe = Rs 320

Case 1.

Loss = 5%

C.P. = Rs 320

Here loss percent and cost price of the shoe is given, we have to find out the selling price(S.P.) of the shoe.

For this we use the formula of calculating S.P.

$S.P. = \frac{C.P.(100-loss\%)}{100}$

On substituting the given values, we get;

$S.P. = \frac{320(100-5)}{100}\\\\S.P. =\frac{320\times 95}{100} =\frac{30400}{100} =Rs\ 304$

The Sell Price of the shoe at 5% loss is Rs 304.

Case 2.

C.P. = Rs 320

Profit = 20%

Here profit percent and cost price of the shoe is given, we have to find out the selling price(S.P.) of the shoe.

For this we use the formula of calculating S.P.

$S.P. = \frac{C.P.(100+profit\%)}{100}$

On substituting the given values, we get;

$S.P. = \frac{320(100+20)}{100}\\\\S.P.=\frac{320\times 120}{100}=\frac{38400}{100}=Rs\ 384$

The Sell Price of the shoe at 20% profit is Rs 384.

Case 3.

C.P. = Rs 320

S.P. = Rs 360

Now we need to find the gain percent.

First we will find the gain.

Gain is the difference of S.P with C.P.

Gain = $360-320 = 40$

Now Gain Percent can be calculated by dividing gain with the cost price and then multiplying it with 100

Gain Percent = $\frac{40}{320}\times 100 = 12.5\%$

Hence The Total Gain Percent is 12.5% when shoes are sold at Rs.360.

The square root of -8 times the square root of -40

Ksju [112]

The answer is: " -8 √5 " .
_________________________________________________________
Note:
_________________________________________________________

√-8 *√-40 = i√8 * i√40 ; {since: "i" refers to the imaginary number; " √-1 " } ;

= i² * √8 *√40 ;
___________________________

Note:

"√8 * √40 = ? " ;

↔ " √8 = √4 √2 = 2√2 " ;

"√40 = √4 √10 = 2√10" ;

→ "√8 √40 = 2 * 2 * √2 * √10 ;

= 4 * √(2*10) ;

= 4 √20 ;

→ " √20 = √4 √5 = 2√5 ;

→ 4 √20 = 4 * 2 * √5

= 8 √5 ;

→ i² * 8 √5 ;

↔ 8 i² √5 ;

Note: " i² = -1" ;

→ 8(-1) * √5 ;

= -8 √5 .
