Question 6 of 10

Maksim231197 [3]

Answer:

(2.5 , 3.5)

Step-by-step explanation:

We can use the midpoint formula . Here the points are , (2,2) and (3,5) .

• Using Midpoint Formula :-

⇒ M = { (x1 + x2)/2 , (y1 + y2)/2 }

⇒ M = ( 2+3/2 , 5+2/2 )

⇒ M = ( 5/2 , 7/2 )

⇒ M = ( 2.5 , 3.5 )

<h3>Hence the midpoint is (2.5 , 3.5)</h3>

Brainly the owner of a hat store buys a hat for 5.50 he uses a markup rate up 105% what is the sale price of the hat

nirvana33 [79]

11.275 is the sale price of the hat

Step-by-step explanation:

Brainly the owner of a hat store buys a hat for 5.50 and he uses a mark-up rate is 105%. Need to find out what is the sale price of the hat.

Here, given data, cost price of hat = 5.5. Let the selling price of hat be x and find the data as asked in question,

$\text {Markup rate}=\frac{S . P .-C . P .}{S . P .} \times 100$

$105=\frac{x-5.5}{5.5} \times 100$

$\frac{105 \times 5.5}{100}=x-5.5$

$\frac{577.5}{100}=x-5.5$

5.775 + 5.5 = x

Where,

S.P - sale price

C.P - cost price

Therefore, x = 11.275 is the sale price of the hat.
