a man spends 1/3 of his wages on food, 1/5 on rent. if he saved the rest what fraction of his wage did he save?

Answers

Total wages = 1
Food = 1/3
Rent = 1/5
Savings = total wages - food - rent
= 1 - 1/3 - 1/5
= 15/15 - 5/15 - 3/15
= 7/15

A square has a side length of x + 3. A regular octagon has a side length of 3x. If the polygons have the same perimeter, determine the value of x.

Answers

Answer:

x = ⅗ = 0.6

Step-by-step explanation:

A square has four equal sides.

If a square has a side length of $x + 3$ , therefore,

Perimeter of the square = $4(x + 3)$

$= 4x + 12$ .

Also, a regular octagon has 8 equal sides.

If it has a side length of 3x, therefore:

Perimeter of the octagon = $8(3x)$

= $24x$

Given that the Perimeter of the rectangle and the octagon are the same, to find the value of x, set each perimeter equal to the other.

Thus:

$24x = 4x + 12$

Subtract 4x from each side

$24x - 4x = 12$

$20x = 12$

Divide both sides by 20

x = 12/20 = ⅗ = 0.6.
