Length of a rectangle is 3 in longer than the width when the perimeter is 54 inches

1 answer:

3 0

Let width be x,
Length: 3+x

P=2(l+w)
54=2(x+(x+3))
54/2=2x+3
27=2x+3
27-3=2x
24=2x
24/2=x
12=x

Therefore, the width is 12 inches and the length is (12+3)=15 inches

Hope I helped :)

The half-life of radium is 1690 years. If 20 grams are present now, how much will be present in 250 years?

Aneli [31]

Answer:

18.05 g

Step-by-step explanation:

The multiplier of the initial quantity is ...

(1/2)^(t/1690)

so, for t=250, this becomes ...

(1/2)^(250/1690) ≈ 0.902545

Then the quantity remaining of the initial 20 g is ...

(20 g)(0.902545) ≈ 18.05 g

X+2y=8 x-2y=-4 solve by system of equations

Vsevolod [243]

Answer:

Step-by-step explanation:

x + 2y = 8 -----------(I)

x - 2y = -4 -----------(II)

Add equation (I) & (II) and thus y will be eliminated and we can get the value of 'x'

(I) x + 2y = 8

(II) <u>x - 2y = -4</u><u> </u>{Now add}

2x = 4

x = 4/2

x = 2

Substitute x = 2 in equation (I)

2 + 2y = 8

2y = 8 - 2

2y = 6

y = 6/2

y = 3
