Please answer! Ignore the work it’s not right

Part A

S = smallest piece

M = medium length piece

L = largest piece

The ratio of the smallest to largest is 2:3, so we can say S = 2x and L = 3x for some positive real number x. The ratio 2x:3x reduces to 2:3.

The third piece (medium length piece) is 1 & 3/4 feet shorter than the longest piece. This means

M = L - (1 & 3/4)

M = L - (1 + 3/4)

M = L - (4/4 + 3/4)

M = L - (7/4)

M = 3x - (7/4)

Add up the three pieces

T = total length

T = S+M+L

T = ( S ) + ( M ) + ( L )

T = ( 2x ) + ( 3x - (7/4) ) + ( 3x )

T = (2x+3x+3x) - 7/4

T = 8x - 7/4

Set this equal to the expression (8/3)x - 7/4 and solve for x

9x - 7/4 = (8/3)x - 7/4

12* [ 8x-7/4 ] = 12*[ (8/3)x - 7/4 ] ... multiply both sides by 12

96x - 21 = 32x - 21

108x = 32x

108x-32x = 0

76x = 0

x = 0/76

x = 0

This is not a useful answer because for example S = 2x = 2*0 = 0, but we can't have a piece of 0 length.

Part B

Instead of (8/3)x - 7/4 feet, we are given a total length of 22 & 1/4 feet.

This is equivalent to the improper fraction 89/4 since

22 & 1/4 = 22 + 1/4

22 & 1/4 = 88/4 + 1/4

22 & 1/4 = 89/4

Let's try to find x now. Set the value of T we got earlier equal to 89/4 and solve for x

T = 8x - 7/4

T = 89/4

8x - 7/4 = 89/4

4*( 8x-7/4) = 4*89/4 multiply both sides by 4 to clear out fractions

32x - 7 = 89

32x = 89+7

32x = 96

x = 3

This is a useful x value because...

S = 2x = 2*3 = 6

M = 3x - 7/4 = 3*3 - 7/4 = 9 - 7/4 = 36/4 - 7/4 = 29/4 = 7 & 1/4

L = 3x = 3*3 = 9

None of the lengths are 0.

Then note how,

T = S+M+L

T = 6 + (7 & 1/4) + 9

T = 6 + (7 + 1/4) + 9

T = (6+9+7) + (1/4)

T = 22 + 1/4

T = 22 & 1/4

Which helps confirm the answers.

There is enough info for her to find the length of each piece in this case. The lengths are

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
