<span>she wanted to buy 6 bottles.
the cost of 10 bottles was $12.
therefore we need to find the cost of one bottle and then find the cost for 6 bottles.                                           
if 10 bottles cost - $ 12                                                                                  
then 1 bottle costs - $ 12 / 10 bottles
                                         
here we divided 12 by 10 , cost of 1 bottle is 12/10 to find the cost of 6 bottles we have to multiply by 6 .12 / 10 x 6
                                                                                 
correct answer is therefore B. divide 12 by 10 and then mulitply by 6</span>

<h2>Answer:</h2>

Option: B is the correct answer.

B.   Step 1:  Divide $12 by 10 to find out the cost of 1 bottle.

Step 2 :  Multiply that cost by 6.

<h2>Step-by-step explanation:</h2>

The cost of 10 bottles is: $ 12.

  • This means that the cost of 1 bottle is:

$ (12/10)=$ 1.2

( Since the cost of  1 bottle will be less and hence the total cost must be divided by the number of items in order to obtain the cost of 1 item)

  • and similarly in order to find the cost of 6 items we need to multiply the cost of 1 item by 6.

Hence, cost of 6 bottles of juice is: $ (1.2×6)=$ 7.2

Hence, the correct answer is:

B.   Step 1:   Divide $12 by 10 to find out the cost of 1 bottle.

Step 2:   Multiply that cost by 6.

Use the distributive property to solve the equation 3.2 = 4/5 (b - 5)
djyliett [7]

Answer:

b=1

Step-by-step explanation:

3.2 = \frac{4}{5} (b - 5)\\3.2 = \frac{4}{5}b - \frac{4}{5} *5\\3.2 = \frac{4}{5}b - 4\\3.2 = -3\frac{1}{5}b\\3.2 = -3.2b\\1 = b\\b= 1

This quarter circle has a radius of 7 centimeters what is the area of this shape?
IgorLugansk [536]

Answer:

153.94

Step-by-step explanation:

I literally just typed in "how to find area of a circle with given radius" to refresh my memory lol. But then all I had to do was type in the radius and it gave me the answer: 153.94

However, if you need the actual steps:

Use the formula: A = πr^2

A = π7^2

A = 49π

A = 153.938 which rounds to 153.94 :)
