Answer:

B

The price of a shirt is marked down from $12.50 to $10,00. What is the percent decrease of the shirt?
choli [55]

Answer: 20%.

Step-by-step explanation:

Given, The price of a shirt is marked down from $12.50 to $10.00.

Previous price = $12.50

New price = $10.00

Change in price = Previous price - New price

= $12.50 - $10.00

= $2.50

Now, the percent decrease of the shirt = \dfrac{\text{Change in price}}{\text{Prevoius price}}\times100

=\dfrac{2.50}{12.50}\times100\\\\=20\%

Hence, the percent decrease of the shirt = 20%.

Help!!!!!!!!!!!!!!!!!!!!!!
zhuklara [117]

Answer:

see below

Step-by-step explanation:

9 ^-5 * 9^-3

When multiplying these we ADD the exponents:

9^-5 * 9^-3

= 9^(-5 + -3)

= 9 ^-8

= 1/9^8  Option A


2.    2^14 / 2^7   This is a division so we SUBTRACT the exponents:-

= 2^(14 - 7)  

= 2^7   (answer)

3.    If the triangle is a right angled one then it will obey Pythagoras Theorem so:-

13^ = x^2 + 5&2

x^2 = 13^2 - 5^2

x^2 = 144

x = 12    (answer)


4.   The last choice is a crucial step.

The total area of the triangles is the same in both large squares so  the area of the large  square e^2 = a^2 + b^2 ( the 2 squares in the left side large square).
