Answer:
Step-by-step explanation:
The formula for determining the area of a rectangular playground is expressed as
Area = length × width
The rectangular playground is 40 meters by 10 meters. This means that the area of the playground would be
Area = 40 × 10 = 400 m²
Each bag of the wooden Chips to be used to cover the playground covers 200 sq meters. The number of bags needed would be
400/200 = 2 bags
Each bag costs $30. Therefore, the total cost for this project would be
2 × 30 = $60
Answer:
$132
Step-by-step explanation:
First we need to find the total number of woods required. This would be total area of fence divided by area of each wood. Remember to convert inch into feet.
Now we know the total number of planks, we need to find what is the cost of each plank. We know that one wood plank area is 2 sq. ft ( 6*0.33333). Therefore, the cost of each plank is = cost per area(sq.ft) multiply by total area (sq. ft).
cost per plank = 2 * $1.10 =$2.20.
We have total planks = 60 units and we have cost per plank = $2.20.
So, we can find total cost as 60*2.20= $132
Let's do this step by step:
Our objective is to find out x.
First, we have to take the '-3' to the right side, and put it next to the 11. When we do this its operation reverses, so it becomes 11 + 3, which is 14.
So we have 9x > 2x + 14.
Then we do the same to the numbers with X, but this time we take the number from the right side to the left. So 2x to the left (reversed) becomes 9x-2x which is 7x.
So 7x > 14
Now let's simplify, 14/7 = 2
so x = 2
N=3 because when you’re multiplying two numbers with a power, you add them to get your answer. so it would be 4^6•4^3=4^9 because 6+3=9, making the only possible value of n, 3.
