An average-sized ant is about \( 4 \times 10^{-3} \) meter long. The circumference of the Earth is about \( 4 \times 10^{7} \) meters. (4) About how many ants would it take to wrap around the Earth?

Classify the equation as a conditional equation, an identity, or a contradiction. \[ -6 x-5+9 x=3 x-5+3 \] select the correct answer below: conditional equation identity contradiction

An unknown compound has the following chemical formula: \[ \operatorname{Cr}(\mathrm{OH})_{\mathrm{x}} \] where \( x \) stands for a whole number. Measurements also show that a certain sample of the unknown compound contains 7.90 mol of oxygen and 2.63 mol of chromium. Write the complete chemical formula for the unknown compound.

The correct Standard Form of the equation \( y=-\frac{1}{3} x+\frac{23}{9} \) :

An airplane with a total mass of 950 kg has an engine malfunction, causing it to provide a constant horizontal force of 3000 N . The pilot, who has a mass of 65 kg , decides to eject from the airplane. With the reduced total mass, what is the new approximate acceleration of the airplane?

\begin{tabular}{l} Evaluating and Solving Exponential Functions \\ \hline Since 1991, the number of fish in Lake Beckett has been decreasing at a rate of \( 1.7 \% \) per year. In 1991, the \\ population of fish was estimated to be 101 million. Use this information to answer the following: \\ \hline a) Write the exponential function \( P(t) \) for this scenario where \( P(t) \) is the fish population in millions \( t \) \\ years after 1991. \\ Exponential Function: \( P(t)= \) \\ b) Determine the number of fish in Lake Beckett in 1996.
