Answer:
144 pages
Step-by-step explanation:
3 hours * 60 = 180 minutes
40 pages / 50 minutes = x pages / 180 minutes
40/50 = x/180
cross multiply
50x = 40 * 180
50x = 7200
x = 7200 ÷ 50
x = 144
Answer:
4times tall
Step-by-step explanation:
Volume of the boxes = Base area × height
Volume of the first box V1 = A1h1
Given the base of the first box to be 5cm, the base area:
A1 = 5cm×5cm = 25cm²
Volume of the first box V1 = 25h1... 1
Similarly, volume of the second box
V2 = A2h2
Given the base of the second box to be 10cm, the base area:
A2= 10cm×10cm = 100cm²
Volume of the second box
V2 = 100h2... 2
If the two boxes have the same volume, then V1 = V2
25h1 = 100h2
divide both sides by 25
25h1/25 = 100h2/25
h1 = 4h2
Since the height of the smaller box is represented as h1, then the height of the smaller base is 4 times tall.
The circumstance of the circle would be 56.55
C= 2πr
C=(2)(π)(8)
= 56.5486677646 round up and it would be 56.55
The fraction is 7/5.
