How to determine the values</h3>
It is important to note that a percentage is the number or ratio expressed as a fraction of 100.
It is denoted using the percent sign, "%"
a. What number is 53% of 43
= 53/ 100 × 43
= 0. 53 × 43
= 22. 79
b. 43% of 300
= 43/ 100 × 300
= 129
c. 12% of what number is 43
12/ 100 × x = 43
x = 43 × 100/ 12
x = 358. 3
d. 43 is what percent of 106
43/106 × 100/ 1
4300×/ 106
40. 5%
e. What percent of 43 is 6
43/ 100 × 6
2.58%
Thus, the percentage of a value is that value divided by 100

I can't understand your question do you have any number there?
Answer:
Work done in stretching the spring = 7.56 lb-ft.
Step-by-step explanation:
Normal length of the spring = 8 in or 
ft
= 
ft
If the spring has been stretched to 11 inch then the stretched length of the spring is = 11 in
= 
ft
Force applied to stretch the spring = 12 lb
By Hook's law,
F = kx [where k is the spring constant and x = length by which the spring is stretched]
12 = k()
k = 18
Work done (W) to stretch the spring by ft will be
W = 
= 
= ![18[\frac{x^{2}}{2}]^{\frac{11}{12}}_0](https://tex.z-dn.net/?f=18%5B%5Cfrac%7Bx%5E%7B2%7D%7D%7B2%7D%5D%5E%7B%5Cfrac%7B11%7D%7B12%7D%7D_0)
= 9()²
= 7.56 lb-ft
The probability that the event won't happen would be .58.
Answer: 29.2cm
Step-by-step explanation: perimeter of parallelogram; 2(a + b) where a = base, b = altitude
a = 8cm
b = 6.6cm
Perimeter = 2(8 + 6.6) = 2(14.6)
Perimeter = 29.2cm
