Answer:

500 lb

Step-by-step explanation:

You have to make a proportion:

\frac{part}{whole} = \frac{percent}{100}

77 lb is part of the whole weight ( which we don't know) so 77 will go on top

The problem tells us that 15.4% of the total weight is pecans so 15.4 will go over 100 (since % are out of 100)

\frac{77}{x} = \frac{15.4}{100}

Then you cross multiply giving you: 7700 = 15.4x

then you divide 15.4 to both sides to isolate x which will give you 500

Which of the following is equal to the rational expression when x ≠ -4 or 16?
stepan [7]

Answer:

C

Step-by-step explanation:

Given

\frac{x^2-16}{(x-16)(x+4)}

The numerator is a difference of squares

x² - 16 = (x - 4)(x + 4)

= \frac{(x-4)(x+4)}{(x-16)(x+4) } ← cancel the common factor (x + 4) on numerator/ denominator

= \frac{x-4}{x-16} → C

Can some one help me with these two
kakasveta [241]

Answer:

11. B

12. D

Step-by-step explanation:

11)

2 times 10⁻² = 2·0.01 = 0.02 ≈ 0.0201

12)

6·10⁻⁴ = 6·0.0001 = 0.0006

However, 0.00058 rounds to 0.0006 and 0.00067 rounds to 0.0007, so the answer is a better estimation for D than for B.
