Is this correct? If it isn’t what’s the correct answer?
alexdok [17]

Answer:

No, it is 6.60

Step-by-step explanation:

We need to know the cost of 1 pound, so we have to do 3.60 divided by 3, to get the cost of 1 pound, which is 1.20

We times 1.20 by the amount of pounds we need, (5.5,) and get 6.60.

If it was times just 5 pounds, than yes, it would be correct, but we need to look out for decimals too.

Convert a 30% markup percent on cost to markup percent on selling price. (Round to the nearest hundredth percent.)
Art [367]

Answer:

Option C

23.08% markup on selling price.

Step-by-step explanation:

Given in the question,

markup percentage on cost price = 30%

To find,

markup percentage on selling price

Markup is the ratio between the cost of a good or service and its selling price.

Let suppose that cost price percentage = 100%

As we know that,

<h3>cost% + markup%  = selling%</h3><h3>100% + 30% = 130%</h3>

So percent markup selling price = 30 / 130 x 100

                                                        = 23.0769

Hence, 30% markup on cost price = 23.0769% markup on selling price.

A student needs to make a circular cardboard piece with an area between 154 square inches and 616 square inches. The function f(
Nezavi [6.7K]
The area of the circle by definition is given by:
 f (r) =  \pi  * r ^ 2&#10;
 For f (r) = 154:
 154 =  \pi  * r ^ 2&#10;
 Clearing r we have:
 r ^ 2 = 154 / 3.14&#10;&#10; r =  \sqrt{154/3.14} &#10;&#10; r = 7
 For f (r) = 616:
 616 = \pi * r ^ 2
 Clearing r we have:
 r ^ 2 = 616 / 3.14 r = \sqrt{616/3.14} r = 14
 Answer:
 
a reasonable domain for f (r) is:
 
7 <r <14

What is the slope of a linear function that passes between (2, 7) and (5, 12)?
Grace [21]

The formula of slope,

→ (y2 - y1)/(x2 - x1)

Then the slope will be,

→ m = (12 - 7)/(5 - 2)

→ [ m = 5/3 ]

Hence, thy slope is 5/3.
