Answer:
Step-by-step explanation:
If the circumference of the circle is x cm the perimeter of the square will be 38-x cm.
The area of the square = (38-x)^2.
The radius r of the circle = circumference /2π = x / 2π.
The area of the circle = πr^2 = π * (x / 2π)^2
= x^2/ 4π.
So total area A = (38 - x)^2 + x^2/4π
A = 1444 - 76x + x^2 + x^2/ 4π
A = x^2 - 76x + 0.07958x^2 + 1444
A = 1.07958x^2 - 76x + 1444
Answer: 0.5049
Step-by-step explanation:
The probability that the first card drawn is a heart is 13/52 = 1/4
The probability that the second card drawn, without replacement, is a spade is 13/51
So the probability of drawing a heart for the first card and spade for the second card is
1/4 + 13/51 = 103 / 204 = 0 5049

I don't have a step-by-step explanation, and I don't know if this is right. It doesn't give me enough time to solve it. If an expert could check this, it would be highly appreciated!
Step-by-step explanation:
1.78 . 1012. 4.55 . 1013
ANS. 1,801.36. ANS. 4,609.15
4609.15 - 1801.36 = 2,80679 kilogram
they are 2,806.79 kilogram aparts
