Hey there! :)
Answer:
$3600.
Step-by-step explanation:
If the wife received $6000 which is a quarter of the money, solve for the total amount of the fortune:
1/4x = 6000
Multiply both sides by 4:
x = $24000
We can begin by subtracting the wife's amount from the total:
24000 - 6000 = $18000
He has 3 sons and 4 daughters. Let 'x' represent the amount the daughters received, and '2x' the amount the sons received.
18000 = 3(2x) + 4(x)
Distribute and combine the terms:
18000 = 6x + 4x
18000 = 10x
Divide both sides by 10:
18000/10 = 10x/10
x = $1800. This is the amount that each daughter receives. Since the sons receive '2x':
2(1800) = $3600.
Answer:
Approximately 13.1521 units.
Step-by-step explanation:
To find the diagonal, we can use the Pythagorean Theorem.
Since the figure is a square, all four sides are equivalent. A square also has four right angles. Therefore, we can use the Pythagorean Theorem to find the diagonal d. Therefore:
Substitute 9.3 for a and b, and let c equal d:
Instead of squaring, add the like-terms:
Take the square root of both sides:
Expand:
The right cancels:
