Answer:

10\sqrt{2}

Step-by-step explanation:

The given is a special right triangle with angle measures as follows:

45-45-90

The side lengths for this special right triangle are represented as follows:

a (the side length that sees angle measure 45)

a\sqrt{2} (the side length that sees angle measure 90)

İn the image we can see that one of the side length that sees angle measure 45 is 10

so c, the side length that sees angle measure 90 (hypotenuse),

is equal to

10\sqrt{2}

Ray wants to buy an item worth $500. Which option is the most cost-effective?
LuckyWell [14K]

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! :)

abruzzese [7]

Answer:

Ella sold the each print for the cost of $57.21.

Step-by-step explanation:

The total number of prints sold at gallery = 52

Total amount it is sold for = $2,975

Noe, If 52 prints are sold for $2,975.

⇒\textrm{Cost of 1 print} =  \frac{\textrm{Total cost of 52 prints}}{\textrm{52}}

= \frac{2,975}{52}  = 57.21

or, Cost of 1 print = $57.21

So, Ella sold the each print for the cost of $57.21.
