Answer 2

Answer:

Ray wants to buy an item worth 500$ in the most cost-effective way. Let's study each of the 3 cases and see with option is the best.

In the first option, he'll buy the item at list price with a coupon for $10 off. So he'll buy it at 500-10 =$490.

In the second option, he'll buy a membership for $35 and then get the item at a 15% discount. With a 15% discount, the price of the item will be 500 - (500*0.15) = 500 - 75 = $425. And with the membership price, he'll pay a total of 425 + 35 = $460.

The third option is to buy the item online at a 10% discount and pay $4 for the shipping. At 10% discount, the price of the item will be 500 - (500*0.1) = 500 - 50 = $450. And with cost of the shipping, he'll pay a total of 450+4 = $454.

So if he chooses the first option, he'll pay $490. With the second, he'll pay $460. And finally with the third, he'll pay $454.

So the third option is the most cost-effective, buying the item at $454.

Hope this helps! :)

According to the pedometer i move 27 5/8 inches when i walk How many feet i will travel in 96 steps?

Answers

I am assuming that is how far you move per step? So, what I did was first multiply 27 5/8 by your 96 steps ( I also converted 5/8 into a decimal so it would be easier so it's 27.625) 27.625*96= 2,652. I divided that by 12 so I could turn that into feet instead of inches; 221 feet.

Inches cubed would be a massive number because the unit is so small, and Centimeters would be even larger. Meters cubed would work, but the standard unit for American homes is usually square footage, and it you're talking about the volume, cubic footage is also the standard.

Johan buys three flats of flowers he plants 2/5 of the flowers and then divides the remaining flowers amongst five friends. What fraction of the flat of flowers does each of Johahn's friends get?

Answers

Answer:

Each friend will get $(9)/(25)$ of the flat of flowers.

Step-by-step explanation:

Johan buys 3 flats of flowers.

He plants $(2)/(5)$ th of the flowers, then the remaining flowers = 3 - $(2)/(5)* 3$

= $(9)/(5)$

Now he divides the remaining flowers among 5 friends.

So each friend gets the fraction of flowers = $\frac{\text{Remaining flowers}}{\text{Number of friends}}$

= $((9)/(5) )/(5)$

= $(9)/(25)$

Therefore, each of Johan's friend will get $(9)/(25)$ of the flat of flowers.

We have to calculate the remaining, or the supplanted flower fraction.
Remaining =1-2/5=(5-2)/5=3/5.

Now, we calculate the fraction of the flat of flowers get by each friend.

Fraction get by each friend=remaining/number of friends
Fraction get by each friend=(3/5)/5=3/25

Answer: 3/25 flat of flowers are got by each friend
