Step-by-step explanation:
Ok, let's pretend that R is 5 and S is 10
That means that Sophie spent 2 hours while Rana spent 4 which means to find the difference you have to subtract. Back to the real problem, we see that we are given R and S not numbers, but variables; as a result, we show the operation then subtract.
Hope this helped my dude.
Answer:
30.5 in
Step-by-step explanation:
All the trianges involved are isosceles right triangles. You know that the hypotenuse is the leg multplied by √2.
ML = KM = KL/√2 = 2/√2
ML = KM = √2
Hope that helps, have a good day :)

This means that about 21 level truck loads are necessary to remove all dirts.</h3>
Step-by-step explanation:
To get the number of level truck loads needed to remove all the dirts in the house, first we need to calculate volume of the truck and the house.
Volume of truck = Length * Breadth * Height
If the truck is 5.0 for the length 2.0 for the height 3.0 for the side base;
Volume of the truck = 5*2*3
Volume of truck = 30
For the house;
Volume of house = Length * Breadth * Height
If the house is 4.0 for the height 14.5 for the length and 11.0 for the side base, then
Volume of the house = 4*14.5*11 = 638
Number of level truck loads needed to remove all the dirts = Volume of house/Volume of the truck = 638/30 ≈ 21.3
This means that about 21 level truck loads are necessary to remove all dirts.
