Pair of listening post is 4000 feet apart they both pick up a soundboard one listening post records the sound 1.5 seconds after the other listing post assume sound travels app 1100 ft per second which equation can be used to determine the possible location to the origin of the sound x2/825 - y2/1,175 = 1
x2/680,625 - y2/3,319,375 = 1
x2/680,625- y2/4,000,000 = 1
x2/ 2,722,500-y2/13,277,500 = 1​

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

correct answer:

b.(19,-2)

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
