21. 1/7 3/8 1/2
23. 3 5/8 3 3/8 3 1/2
25. 1/6 3/4 2/3
Answer:
Option A is correct

Step-by-step explanation:
Let the number be z.
Given the statement:
'' five times the quotient of some number and ten"
" quotient of some number and ten" translated to 
"five times the quotient of some number and ten" translated to 
Then, the expression we get,

Therefore,
expression represents '' five times the quotient of some number and ten"
Is it a yardstick? It has 2 ft of the edges and one ft in the middle.
Answer:
Container B has smaller surface area.
Step-by-step explanation:
Given:
Container A
Radius = 60/2 = 30 mm
Height = 4 x 60 = 240 mm
Container B
Length = 120
Width = 120
Height = 60
Computation:
Surface area of container A (Cylinder) = 2πr[h+r]
Surface area of container A (Cylinder) = 2[22/7][60][120+60]
Surface area of container A (Cylinder) = 67,885.70 mm² (Approx)
Surface area of container B (Cuboid) = 2[lb+bh+hl]
Surface area of container B (Cuboid) = 2[(14,400)+(7,200)+(7,200)]
Surface area of container B (Cuboid) = 57,600 mm²
Container B has smaller surface area.
The slope is mx+b so find two points in the graph and use y-rise/x-run
