Which statements are equivalent to -2.5< 8/13
1 answer:
<u>The question looks to be incomplete (without the appropriate choices). But still answering related to the inequalities part:</u>
Inequalities are the relationships between two expressions which are not equal to one another. The symbols used for inequalities are <, >, ≤, ≥ and ≠.
reads as '7 is greater than x' (or ' x is less than 7', reading from right to left). Here above, Statements are equivalent when both sides are true or logically the inequality holds good here.
We have , -2.5<8/13 . which is equivalent to -2.5< 0.615 which holds true. We know that any negative number is always smaller than any positive number, also less than 0. And , -2.5 value is less than 0.615. ∴ Inequality holds good!

Answer:
The bird has to fly 7.5 m
Step-by-step explanation:
Please see diagram in attached image.
Notice that there is a right angle triangle that defines the situation, and you know two elements of such triangle;
1) one acute angle (), and
2) the side opposite to that angle.
What you need to find is the side adjacent to the angle, which is what the bird needs to fly horizontally to be above the fish. We named that "x".
The trig function that relates such triangle elements is the tangent:
which rounded to the nearest tenth is: 7.5 m
