a) If this trend continues, how many birds will be left by 2010 will be 525
b) The birds would there have been in 1990 will be 2475
<h3>What is rate of increase?</h3>
Rate of increase or decrease is defined as the increment or decrement in any quantity over a period of time constantly.
Here we have the data that:
There were 1500 birds in 2000 and they are decreasing at an annual rate of 6.5%.
a) If this trend continues, how many birds will be left by 2010
{1500x6.25}/{100}=97.5
So the bird decrement in the one year will be =97.5 so it will be in the 10 years or upto 2010 will be
97.5x10=975
So the birds left till 2010 will be:
Q=1500-975=525
b)The birds would there have been in 1990 will be:-
=1500+975=2475
Hence If this trend continues, how many birds will be left by 2010 will be 525.The birds would there have been in 1990 will be 2475

Answer: Everybody gets 5 marbles a piece because he took to of his favorite away which leaves 45 and 9 times 5 is 45 so yeah
Step-by-step explanation:
The final answer would depend in the type of triangle we are analyzing, however here are the possible outcomes:
1.) If it was a right triangle, 36.5 would be the smaller angle.
2.) It cannot be an equilateral triangle since all angles would be 60°.
3.) In a isosceles triangle, 36.5° would be the smaller, since the others would be 72°.
4.) In an scalene triangle it cannot be determined unless we had 2 angles since in that kind of triangle all angles can be different.
5.) In an acute triangle, 36.5° would be the smaller angle.
6.) In an obtuse triangle it cannot be determined unless we had 2 angles, since it can have highly acute angles.
Answer:
6 square units
Step-by-step explanation:
In oder to do this, you need graph paper to make it easier and then mark your graph paper with the quadrants.
I got 3 unites for the height and 4 units for the base
4 x 3 = 12 square units
however the formula for a triangle is Ab/2
so divide 12/2 = 6
So its 6 square units
