Answer:

Other diagonal is 98.5 inches long.

Step-by-step explanation:

Formula to get the measure of diagonals of a parallelogram is,

x^2+y^2=2(a^2+b^2)

where x and y are the lengths of the diagonals and a and b is the measure of two non parallel sides.

If a = 50 inches, b = 80 inches and x = 90 inches,

then from the given formula,

90² + y² = 2(50² + 80²)

y² = 2(2500 + 6400) - 8100

y² = 17800 - 8100

y = \sqrt{9700}

y = 98.49

  ≈ 98.5 inches

Therefore, other diagonal of the parallelogram is 98.5 inches long.

i have 30 coins, all nickels, dimes and quarters, worth $4.60. there are two more dimes than quarters.. how many of each kind of
Oliga [24]

Answer:

Step-by-step explanation:

I have 30 coins, all nickels, dimes, and quarters, worth $4.60. There are two more dimes than quarters. How many of each kind of coin do I have.

..

let quarters be x

dimes = x+2

...

dimes + quarters = x+x+2=2x+2

...

nickels = 30-(2x+2)

...

5(30-(2x+2))+10(x+2)+25x=460

5(30-2x-2)+10x+20+25x=460

150-10x-10+10x+20+25x=460

160+25x=460

-160

25x=460-160

25x=300

/25

x=300/25

x=12 ---- quarters

x+2= 12+2=14 dimes

30-(2x+2)=4 nickels

...

check

4*5+14*10+12*25=20+140+300=460
