Distance formula = sqrt ((x2 - x1)^2 + (y2 - y1)^2)
(20,-4)...x1 = 20 and y1 = -4
(-4,3)...x2 = -4 and y2 = 3
now we sub
d = sqrt ((-4 - 20)^2 + (3 - (-4)^2)
d = sqrt ((-24^2) + (7^2))
d = sqrt (576 + 49)
d = sqrt 625
d = 25 <==

lisabon 2012 [21]

Answer: Length of smallest piece is 3.43 feet.

Length of middle piece is 2× 3.43 = 6.86 feet

Length of largest piece is 4× 3.43 = 13.72 feet.

Step-by-step explanation:

Let the length of smallest piece be x

According to question, the middle piece is twice the length of the smallest piece.

So, length of middle piece be 2x

According to question, the largest piece is twice the length of the middle piece.

So, length of largest piece be 2(2x)=4x

Total length of pipe = 24 ft

So, it becomes,

x+2x+4x=24\\\\7x=24\\\\x=\dfrac{24}{7}\\\\x=3.43\ ft

Length of smallest piece is 3.43 feet.

Length of middle piece is 2× 3.43 = 6.86 feet

Length of largest piece is 4× 3.43 = 13.72 feet

Alex

Answer: $140

Step-by-step explanation:

1/4 × 560 to buy a coat

= 0 25 x 560 = $140

Remaining balance after purchase of coat will be $560 - $140 = $420

Next, he uses 2/3 of $420 for present

2/3 × 420

0.667 x 420

= $420 - $280

=$140
