Can someone translate it?: What's the fastest animal in the world?
Answer (2)
The fastest animal in the world is the peregrine falcon, capable of reaching speeds over 240 miles per hour during its hunting stoop. It is found globally, except for extreme polar regions, and its speed is due to its aerodynamic shape and powerful muscles. In contrast, the cheetah is the fastest land animal but does not match the falcon's speed in flight.

Evaluate each expression.
E = -8 + 4/7 = -7.42857...
F = 7 - 0.5 = 6.5
G = 9 + (-3) = 6
H = 3.8 - 6.7 = -2.9
The only integer result is G = 6, so the answer is G .
Explanation
Understanding the Problem We are given four numerical expressions and we need to determine which one evaluates to an integer. An integer is a whole number (not a fraction). We will evaluate each expression and check if the result is an integer.
Evaluating Expression E Let's evaluate expression E: E = − 8 + 7 4 . This is equal to − 8 + 0.5714... = − 7.42857... which is not an integer.
Evaluating Expression F Now, let's evaluate expression F: F = 7 − 0.5 = 6.5 , which is not an integer.
Evaluating Expression G Next, let's evaluate expression G: G = 9 + ( − 3 ) = 9 − 3 = 6 , which is an integer.
Evaluating Expression H Finally, let's evaluate expression H: H = 3.8 − 6.7 = − 2.9 , which is not an integer.
Final Answer Therefore, the only expression that evaluates to an integer is G, which equals 6.
Examples
Imagine you're splitting tasks among friends. Some tasks take whole hours, others fractions of an hour. This problem helps you identify which task durations result in a whole number of hours, making scheduling easier. For example, if one task takes 9 hours and another reduces the workload by 3 hours, the net task time is 6 hours, a whole number.
