Answer:
Add all of them together. So your answer is
61/10 or 6 and
Step-by-step:
7/5 =1 and 2/5 or 14/10
1/2= 5/10
4/1 or 4= 40/10
14/10 + 5/10 + 40/10 = 61/10
Simplified: 6 and 1/10
Answer:
142.5
Step-by-step explanation:
You multiply the base of the triangle and the width. Then divide it by 2
Answer:
-2y=10x-24
y= -5x+12
Step-by-step explanation:
Answer: After 7 years the number of birds of species A and B are same. and the number of birds during that year will be 140.
Step-by-step explanation:
Given: Sharon is conducting research on two species of birds at a bird sanctuary.
The number of birds of species A is represented by the equation below,where S represents the number of birds, x years after beginning her research.
![S=2^x+12](https://tex.z-dn.net/?f=S%3D2%5Ex%2B12)
The number of birds of species B is represented by the equation below,where S represents the number of birds, x years after beginning her research.
![S=15x+35](https://tex.z-dn.net/?f=S%3D15x%2B35)
To plot the above function, first find points by which they are passing.
For species A, At x=0 , ![S=1+12=13](https://tex.z-dn.net/?f=S%3D1%2B12%3D13)
At x=2 , ![S=2+12=14](https://tex.z-dn.net/?f=S%3D2%2B12%3D14)
Similarly find more points and plot curve on graph.
For species A, At x=0 , ![S=0+35=35](https://tex.z-dn.net/?f=S%3D0%2B35%3D35)
At x=2 , ![S=15+35=50](https://tex.z-dn.net/?f=S%3D15%2B35%3D50)
Plot a line with the help of these two points.
Now, from the graph the intersection of curve (for A) and line (for B) is at (7,140) which tells that After 7 years the number of birds of species A and B are same. and the number of birds during that year will be 140.
