Answer:

2 1/4 yards above sea level

Step-by-step explanation:

The midpoint elevation is the average of the endpoint elevations, their sum divided by 2. When elevation is below sea level, it is represented by a negative number.

(17 3/4 - 13 1/4)/2 = (4 2/4)/2 = 2 1/4 . . . yards above sea level

Ned has a coupon for one fourth off the cost of any item. Today all items are on sale for one third off. Does it matter whether

Aleksandr [31]

Answer:

Step-by-step explanation:

Let the cost of the item is C.

Case I :

first sale is applied

so, the price of item = one third = C - C/3 = 2C/3

Now coupon is applied

so, the price of item = $\frac{2C}{3}-\frac{1}{4}\times \frac{2C}{3}$ = C/2

case II :

First coupon is applied

so, the price of item = C - C/4 = 3C/4

Now sale is applied

the price of item = $\frac{3C}{4}-\frac{1}{3}\times \frac{3C}{4}$ = C/2

So, it does not matter that either coupon is applied first or the sale is applied first the final cost of the item remains same.

Simplify. (c/3)^-2 A. c²/9 B. 9/c² C. 1/9c² D. 9c²

torisob [31]

The same applies to this one as well...we have a fraction of C/3 and the whole fraction has the exponent of -2.

C^-2 / 3^-2 = C^-2 / 9....we can't have a negative exponent in the numerator, so we send it to the bottom and make it a positive...

9 / C^2
