Answer:
Step-by-step explanation:
For all shapes, the surface area will go up by a factor of 9 (3^2). This is true of spheres, cones, cubes, pyramids, torusses, everything.
The surface area of any body is proportional to the square of any linear dimension. Triple a linear dimension and you get a 9 fold increase in surface area. This is as true for pretzels as it is for spheres and cubes.
Answer:
a=31.61
Step-by-step explanation:
Pythagorean theorem states that square hypotenuse side is equal to square opposite side plus square adjacent side
Hyp²= Opp²+Adj²
the opposite is represented by a in the question, so
60²=a²+51²
3600=a²+2601
combine the like terms
3600-2601=a²
999=a²
a²=999
square root both sides to remove the square
√a²=√999 {square cancels the square root
a=√999
a=31.606
a=31.61 approximately
Answer:
Her centripetal acceleration during the turn at each end of the track is 
Step-by-step explanation:
Total distance covered in one round , D= 400 m
Time taken to cover one round , T = 1 min 40 s = 100 sec
Speed of runner , 
Now centripetal acceleration is given by

where 


Thus her centripetal acceleration during the turn at each end of the track is 
Answer:
11x11=121
Step-by-step explanation:
121 is equal to 11 times 11.
When the daughter cells split or divide from the parent cell, it is called cytokinesis. :)
