Step-by-step explanation:

The common difference of an arith. seq. is the distance between any two adjacent members of the sequence.

The difference (increase) between -1 and 10 is +11.

as a check, determine whether adding 11 to y = 10 results in 21. Yes, it does.

The common difference here is 11.

5^10/5^3 rewrite in the form of 5^n

Sergeeva-Olga [200]

Answer:

5^7

Step-by-step explanation:

To rewrite the expression, you use the laws of exponents.

Using the law of exponents of division, you subtract the exponent of the smaller value (5^3) from the larger value (5^10).

Your expression would now be this:

5^10-3

Since the bases have the same value (5), they remain the same.

As a result of 5^10-3, you would get 5^7 as your answer.

To check that both are equivalent to each other you solve and find the values of both expressions.

5^7=78125

5^10/5^3=78125

5^7=5^10/5^3

A shopkeep offers a discount of 20% on all the articles at his shop and still makes a profit of 12%. What is the CP of an articl

Arte-miy333 [17]

Given info:-

A shop keeper offers a discount of 20% on all the articles at his shop and all makes a profit of 12%.

What is the CP of an article whose MP is Rs. 280 ?

Explanation:-

Given that

The Marked Price of an article (M) = Rs. 280

Discount on it = 20%

Discount (D) = MD/100

⇛ Discount = (280×20)/100

⇛ Discount = 28×2

⇛ Discount =56

Selling Price = Marked Price - Discount

⇛ Selling Price = 280-56

⇛ Selling Price = Rs. 224

Selling Price of the article = 224

Profit on it = 12%

We know that

Cost Price = (100×SP)/(100+g)

⇛ CP = (100×224)/(100+12)

⇛ CP = 22400/112

⇛ CP = 200

Therefore, The CP = Rs. 200

The Cost Price of the article = Rs. 200.

Formula:-

Discount (D) = MD/100

M = Marked Price

Selling Price = Marked Price - Discount
Cost Price = (100×SP)/(100+g)

SP = Selling Price

g = gain or profit
