<span>The reciprocal of a fraction is simply the reverse
position of the original fraction, its numerator and denominator. It is
represented by the formula of 1/number (fraction). To get the reciprocal of the
number, divide one by the fractional number. You are given the number 6/5. So you
have a numerator of 6 and a denominator of five. Simply swap them and you get
the new numerator as 5 and the new denominator as 6. Or you can just divide
1/(6/5) then you will get 5/6. The answer is letter D.</span>
That means that the first rectangle and the first triangle ave athe same perimiter
so therefor
perimiter=sides added up
rectangle has 4 sides bu 2 is given so double it since the other side is same legnth
rec=x+x+4
multiply 2
2x+2x+8=4x+8=perimiter
this is equal to perimiter of triangle which is
x+9+x+5+x=3x+14
therefor
4x+8=3x+14
subtract 3x from both sides
x+8=14
subtract 8 from both sides
x=6
first one x=6
second rectangle and second triangle
s+7 and 3s
2 sides
2s+14+6s=p
8s+14=p
traignel=2s+12+2s+12+2s+12=6s+36=p
they are equal so
8s+14=6s+36
subtract 6s from both sides
2s+14=36
subtract 14 from both sides
2s=22
divide both sideds by 2
s=11
the values are
pair one:
x=6
pair 2:
s=11

Answer:
A motor running at 75 revolutions per second.
Step-by-step explanation:
Given statement: A motor running at 4500 RPM, revolutions per minute.
⇒ In one minute , a motor running at 4500 revolutions.
Use conversion:

We have to calculate how many revolutions per second.
in 60 sec , a motor running at 4500 revolutions
then,
in 1 sec , a motor running at
revolutions.
Therefore, a motor running at 75 RPS, revolution per second.
