sutopa has 3/4 the money maneet has. maneet has $18 less than Kim. together, they have $286.40. How much money does each of them
timurjin [86]

The amount of money Kim, maneet and Sutopa have is $115.6, $97.6 and $73.2 respectively.

<h3>Equation</h3>

  • Kim = x
  • Maneet = x - 18
  • Sutopa = 3/4(x-18)
  • Total = $286.40

x + (x - 18) + 3/4(x-18) = 286.40

x + x - 18 + 3/4x - 13.5 = 286.40

2 3/4x = 286.40 + 13.5 + 18

11/4x = 317.9

x = 317.9 ÷ 11/4

= 317.9 × 4 / 11

= 1,271.6 / 11

x = $115.6

So,

Kim = x

= $115.6

Maneet = x - 18

= 115.6 -18

= $97.6

Sutopa = 3/4(x-18)

= 3/4(97.6)

= $73.2

The shorter leg of a 30°-60°-90° right triangle measures 5 in. What is the length of the longer leg?
DedPeter [7]
The relationship of the angles to the sides opposite those angles is always:

30°=1, 60°=√3, and 90°=2

So the longer leg can be found using the ratios from above...

L/S=√3/1 and we are told that the shorter side is 5 in so

L/5=√3

L=5√3

So A. is the correct answer.
