The figure below shows a shaded rectangular region inside a large rectangle:
SSSSS [86.1K]

Answer:

Step-by-step explanation:

The formula for determining the length of a rectangle is expressed as

Area = length × width

The large rectangle has a length of 10 units and width 5 units. The area of the large rectangle would be

10 × 5 = 50 units²

Inside this rectangle is a smaller rectangle of length 4 units and width 2 units. The area of the smaller rectangle would be

4 × 2 = 8 units²

Probability is expressed as favorable outcome/total number of possible outcomes

The region that is not shaded grey is

50 - 8 = 42 units²

The probability that a point chosen inside the large rectangle is not in the shaded region is

42/50 = 0.84

Converting to percentage, it becomes

0.84 × 100 = 84%

i When 20 is added to a certain number and the sun is divided by 3, the result is 3 times the number, find the number.​
Bingel [31]

Answer:

let \: the \: number \: be \: x \\  \frac{20 + x}{3}  = 3x \\  \frac{3(20 + x)}{3}  = (3x)3 \\ 20 + x = 9x \\ 20 = 9x - x \\ 20 = 8x \\  \frac{20}{8}  =  \frac{8x}{8}   \\ x = 2.5

Step-by-step explanation:

Hope that this is helpful .

Have a great day.
