Answer:
88 cm
Step-by-step explanation:
The side of the square = 6 cm, so the shorter side of each rectangle = 6 cms.
The area of each rectangle = 36 * 1 1/3
= 36 * 4/3 = 48 cm^2
So the longer side of each rectangle = 48 / 6 = 8 cms
Therefore, the perimeter of the whole figure
= 4( shorter sides ) + 8(longer sides)
= 4*6 + 8*8
= 24 + 64
= 88 cm (answer)
The pile contains 17 quarters and 15 half-dollars.
Let <em>x</em> = the number of quarters and <em>y</em> = the number of half-dollars.
We have two equations:
(1) $0.25<em>x</em> + $0.50<em>y</em> = $11.75
(2) <em>x</em> = <em>y</em> +2
Substitute the value of <em>x</em> from Equation (2) into Equation (1).
0.25(<em>y</em>+2) + 0.50<em>y</em> = 11.75
0.25<em>y</em> + 0.50 + 0.50<em>y</em> = 11.75
0.75<em>y</em> = 11.75 – 0.50 = 11.25
<em>y</em> = 11.25/0.75 = 15
Substitute the value of <em>y</em> in Equation (2).
<em>x</em> = 15 + 2 = 17
The pile contains 17 quarters and 15 half-dollars.
<em>Check</em>: 17×$0.25 + 15×$0.50 = $4.25 + $7.50 = $11.75.
