PLEASE HELP MEEEEEEEEEEEEEEEEEE

Perimeter of the carpet = 21.8 m

Area of the carpet = $29.4 $ m^{2}$

Given:

Dimension of the living room:

$l = 4.9 $ m\\w = 6 $ m$

A. Perimeter of the carpet = perimeter of a rectangle

Perimeter = $2(l + w)$

Substitute

$Perimeter = 2(4.9 + 6)\\= 21.8 $ m$

Perimeter of the carpet = 21.8 m (The digits here are significant)

B. Area of the carper = area of a rectangle 

Area = $l \times w$

Substitute

$Area = 4.9 \times 6\\= 29.4 $ m^{2}$

Area of the carpet = $29.4 $ m^{2}$ (the digits here are significant)

Therefore, considering the rules of significant digits:

Perimeter of the carpet = 21.8 m

Area of the carpet = $29.4 $ m^{2}$

The weather forecast says there’s 70% probability of rain tomorrow. What are the odds against rain

krok68 [10]

Answer:

30%

Step-by-step explanation:

Key skills needed: Probability

1) There is a 70% chance of rain.

2) We need to find the chances against rain.

3) To do this, we need to use the fact that

70% + x = 100% (Since all the probabilities add up to 1 or 100%)

4) If you subtract 70% from both sides, x = 30%

5) This means the probability against rain is 30%.

Hope you understood and have a nice day!! :D
