Answer:
134.189
Step-by-step explanation:
1+ 4x√7
√7 = 2.646
=4 x 2.646 = 10.584
1+10.584= 11.584
11.584 squared
=134.189
Answer:
Step-by-step explanation:
If 4 hole need to complete in 25 minutes than 1 hole need to fine in how many minute
Than 25÷4=6.25 one hole
6.25×13= 81.25
Answer:
B. 19 inches and 60 inches.
Step-by-step explanation:
Required
Select matching pairs
Represent diameter with D and Circumference with C
C is calculated as:
Where
A. D = 5m; C = 22m
Using:
15.71 does not approximates to 22m.
Hence, the pair do not match
B. D = 19 in; C = 60 in
Using:
59.698 approximates to 60.
Hence, the pair match
C. D = 33 cm; D = 80 cm.
Using:
103.686 does not approximates to 22m.
Hence, the pair do not match
From the analysis above, only option B matches the diameter with the circumference
In a mechanical system, it is a law that energy should be conserved. In this case, what is the initial energy should be equal to the total energy after the motion happened. We do as follows:
PE(at rest) = KE(during motion) + PE(after motion)
51450 J = KE(during motion) + 32781 J
KE(during motion) = 18669 J
