Answer:

Choice 1

m^2 +n^2=13^2

m^2=13^2-n^2

n^2=13^2-m^2

Both m & n =(13 x sq rt 2)/2

To put it another way:

m=(sq rt 2)/2 x 13

n=(sq rt 2)/2 x 13

If 1/a, 1/b, 1/c are in Arithmetic Progress, show that 2ac/a+c.

Iteru [2.4K]

1/b-1/a = 1/c-1/b [ since they are in arithmetic progress]
1/b+1/b = 1/c+1/a
2/b = (a+c)/ac
2ac = b(a+c)
2ac/(a+c) =b

Kitty [74]

Answer:

The inequality for amount x (in dollars) is given by

x ≤ $33 - (cost of necklace).

Step-by-step explanation:

Let the cost of the necklace be $ y.

The amount for the necklace is constant and it is less than $33 and it is also known that the amount for the necklace will be spent.

Therefore after the necklace has been purchased and the amount deducted from $33 the remaining amount can be used completely or partly to purchase the other item.

Let the cost in dollars of the other item be $x.

The inequality for amount x (in dollars) is given by

x ≤ $33 - (cost of necklace)
