Mr. Lafond is building a rectangular dog run in his backyard. He uses 86 feet of fencing to enclose the dog run. The dog run is

prohojiy [21]

Here,

Perimeter (P)=86 feet

Length (l)=25 feet

Let, width(b)= x feet

Then,

Perimeter= 2(l+b)

86=2(25+x)

43=25+x

x=18

Hence, required width is 18 feet...

The sum of two segments are 75 cm, and one the segments are four times the other. Calculate the measurement of each segment

iVinArrow [24]

The length of one segment is 15 cm and other segment is 60 cm

Step-by-step explanation:

Let x be the length of one segment and y be the length of other segment

Then according to given statement

x+y=75 Eqn 1

And

one the segments are four times the other

x=4y Eqn 2

$Putting\ x=4y\ in\ equation\ 1$

$4y+y=75\\5y=75\\Dividing\ both\ sides\ by\ 5\\\frac{5y}{5}=\frac{75}{5}\\y=15\\Putting\ y=15\ in\ eqn\ 2\\x=4(15)\\x=60$

Hence,

The length of one segment is 15 cm and other segment is 60 cm
