Answer:
Step-by-step explanation:
b(a + 1) + a = b*a + b + a = ab + b + a
1) b(2a +1 ) = b*2a + b*1 = 2ab + b Not equivalent.
2)a + (a +1)*b = a + ab+ b Equivalent
3) (a +1)(b+ a) = a*(b +a) + 1*(b+a) = ab+ a² +b + a Not equivalent.
4) (a + 1)b + a = ab+ b + a Equivalent
5) a + b(a+1) = a +ab + b Equivalent
6) a + (a +1) + b = a + a + 1 + b = 2a + 1 +b Not equivalent.
7) a(b +1) + b = ab + a + b Equivalent
1999 price = 11900
it depreciates 13%
year 2000 cost = 11900 - 1547 = 10353
it depreciates 13%
year 2001 cost = 10353 - 1345.89 = 9007.11
it depreciates 13%
year 2002 cost = 9007.11 - 1170.92 = 7836.19

Answer:
a) 376.66
b) Option 2: No, the result from part (a) could not be the actual number of adults who said that rising gas prices are "quite annoying" because a count of people must result in a whole.
c) 377
d) 40.77%
Step-by-step explanation:
a) 37% of 1018 is;
37/100 × 1018 = 376.66
b) Thus, the result in a above is not a whole number. Thus;
No, the result from part (a) could not be the actual number of adults who said that rising gas prices are "quite annoying" because a count of people must result in a whole.
c) from a above a, we got a value of 376.66.
Now the actual number would be preferably an integer. Thus, actual number is approximately 377.
d) percentage of respondents said that cellular phones are not at all harmful = 415/1018 × 100% = 40.77%
Answer:
1/2
Step-by-step explanation:
![y = \sqrt[3]{\frac{1}{8x}}\\\\=\sqrt[3]{\frac{1}{2*2*2*x}}\\\\=\frac{1}{2}\sqrt[3]{\frac{1}{x}}](https://tex.z-dn.net/?f=y%20%3D%20%5Csqrt%5B3%5D%7B%5Cfrac%7B1%7D%7B8x%7D%7D%5C%5C%5C%5C%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B1%7D%7B2%2A2%2A2%2Ax%7D%7D%5C%5C%5C%5C%3D%5Cfrac%7B1%7D%7B2%7D%5Csqrt%5B3%5D%7B%5Cfrac%7B1%7D%7Bx%7D%7D)
