prem gave 1/3 of his property for charity of the rest he gave 2/3 to his wife and rest divided equally between his son and daugh

Anna11 [10]

Given parameters:

Fraction given to charity = $\frac{1}{3}$

Fraction given to wife = $\frac{2}{3}$

Unknown:

Fraction given to son and daughter =?

Solution:

Let the total property = x

Fraction given to charity = $\frac{1}{3} x$

Fraction given to wife = $\frac{2}{3} x$

The remaining was given to son and daughter = F

So;

Total property = fraction given to charity + fraction given to wife + fraction given to son and daughter

x = $\frac{1}{3} x + \frac{2}{3} x + F$

F = x - ( $\frac{1}{3} x + \frac{2}{3} x$ )

F = 0

The son and daughter will not inherit anything

Given the graph, find the distance of GH. Round to the nearest tenth.

lord [1]

Answer:

GH = 6.3 units

Step-by-step explanation:

Assuming that 1 box represents 1 unit, the coordinate pair of G = (-2, -3), while H = (0, 3).

Distance between G and H = $d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Let,

$G(-2, -3) = (x_1, y_1)$

$H(0, 3) = (x_2, y_2)$

$GH = \sqrt{(0 - (-2))^2 + (3 - (-3))^2}$

$GH = \sqrt{(2)^2 + (6)^2}$

$GH = \sqrt{4 + 36} = \sqrt{40}$

$GH = 6.3 units$ (nearest tenth)
