Answer:
The area of the rectangular playroom is 260 feet² .
Step-by-step explanation:
Given:
The perimeter of the rectangular playroom is 72 feet and it's width is 10 feet.
Now, to find its area we need the length .
So, putting the formula of perimeter we get it's length:
Let the length be l .
Perimeter = 2( length + width)
subtracting both sides from 20:
Dividing both sides by 2:
Length is 26 feet.
And, to get the area we put the formula of finding the area:
Therefore, the area of the rectangular playroom is 260 feet² .
Answer: There are 9 outcomes in this experiment.
Step-by-step explanation:
Rock-Paper- Scissor is a simple game, in which Rock beats scissor, scissor beats paper, paper beats rock. If any two people made the same gesture it will be a tie.
So if two roommates are playing the game , total outcomes in the sample space = 3 x 3 [By fundamental principal of counting]
= 9
Hence, there are 9 outcomes in this experiment.
Answer:
a = 18
Step-by-step explanation:
a/6 = 3
Multiply each side by 6
a/6*6=3 *6
a = 18
Multiply:
1.17 x 1.5 = 1.755
rounded to 2 places = 1.76 minutes
