Do a proportion and then youll get the things you need to make the equation using x =
First, add the total of all marbles in the bag: 3+2+7=12. this will be our denomonator. the probability is just the number of marbles in this question. there are three green marbles out of 12, and since you cannot simplify, that is your probability: 3/12
First, determine the width of the court by dividing the area by the length.
width = area / length
width = 162 m²/18 m = 9 m
Then, determine the perimeter of the court by the equation
P = 2L + 2W
where L and W are length and width, respectively.
P = 2(18m) + 2(9m) = 54 m
Given that every 20 m roll of tape costs $2.79, and even if the court is only 54 m, Jeff still needs to buy 3 20-m roll
total cost = ($2.79) x 3 = $8.37
Thus, the answer is letter B.
Answer:
The area is 452 cm2
Step-by-step explanation:
We use the formula:
Area = π (raduis)2 =π (12cm)´2 = 452, 39 cm2
