Answer:
Cost = 1440 × 1.86
Cost = $2678.4
Step-by-step explanation:
The flooring costs $1.86 per square foot, or each foot squared.
First, find the total area covered by the warehouse floor.
Do this by multiplying the width of the floor by the length to find the area.
A = 30 × 48
A = 1440 feet²
Now, one square foot costs $1.86. Therefore, finding how much 1440 square feet costs will look as follows:
Cost = 1440 × 1.86
Cost = $2678.4

<h3>
Answer: 1/2 of the container</h3>
Explanation:
Draw a circle and split it into thirds. The sister will take one of the slices, so we have 2 left over. That accounts for the 2/3 left over.
Then split each of those two slices in half to get 2*2 = 4 smaller slices. The mother takes 3 of those smaller slices which represents 1/2.
Or you could say (2/3)*(3/4) = (2*3)/(3*4) = 2/4 = 1/2.
The diagram is shown below. The white portion is the 1/3 the sister gets at first. The pink portion represents the fractional amount the mother drank, which is 3/6 = 1/2.
