Answer:
1078
Explanation:
For this you can use a proportion to solve. So first we set up the proportion as laptop over desktop is equal to "<em>l</em>" over total desktop computers. Let <em>l</em> be the total amount of laptops which is what we must first solve for.
Then we cross multiply.
Now we can solve it as a regular algebra problem,
Now that we know how many laptop computers there are we can find the total number of computers in the school. We simply add the total number of desktop computers to the total number of laptop computers.
And that is the answer. 1078.
Option D:
160 plastic cubes can fit into the box.
Solution:
Convert mixed fraction into improper fraction.
Length of the box = 4 ft
Width of the box = ft
Height of the box = 2 ft
Volume of the box = length × width × height
= 20 ft³
Volume of the box = 20 ft³
Length of the plastic cube = ft
Volume of the cube = length × length × length
Volume of the cube = 0.125 ft³
= 160
Number of plastic cubes = 160
Hence 160 plastic cubes can fit into the box.
Option D is the correct answer.
