Answer:
24 birds
Step-by-step explanation:
Let b represent the number of birds at the shelter on Wednesday. Then the cost of care for the 41 animals is ...
5b +7.5(41 -b) = 247.50
-2.5b +307.50 = 247.50 . . . . . simplify
-2.5b = -60 . . . . . . . . . . . . . . . . subtract 307.50
b = 24 . . . . . . . . . divide by -2.5
The number of birds at the shelter on Wednesday was 24.
The meaning of circumference is to find the distance around a circle or in other words perimeter by using the formula C=2πr or C=<span>πd.
On this case it is asked you to find the circumference of a circle with a diameter of 3 meters, so you will use the formula C=2</span><span>πr.
C=2</span><span>πr
C=2(3.14)(3)
C=18.84 meters
The circumference of the given circle is 18.84 meters.</span>
Note:
The slope of a straight line passing through the points (x₁, y₁) and (x₂, y₂) is

The two given points are (-3,4) and (4,-1). Therefore the slope is
