Answer:

$m < 1 = 180 \degree - 123\degree \\ = 57\degree$

$m < 2 = 180\degree - 57\degree - 48\degree \\ = 75\degree$

$m < 3 = 180\degree - 123\degree - 13\degree \\ = 44\degree$

Answer:

∠1 = 180° - 123° = 57°

∠2 = 180° - 57° - 48° = 75°

∠3 = 180° - 123° - 13° = 44°

Answer:

3 bags

Step-by-step explanation:

Suppose there are

bags of candy.

If the

blue gumballs are to be split evenly with no leftovers among the

bags, then

must divide evenly into

If the

green gumballs are to be split evenly with no leftovers among the

e-lub [12.9K]

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.

$S=2^x+12$

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.

$S=15x+35$

To plot the above function, first find points by which they are passing.

For species A, At x=0 , $S=1+12=13$

At x=2 , $S=2+12=14$

Similarly find more points and plot curve on graph.

For species A, At x=0 , $S=0+35=35$

At x=2 , $S=15+35=50$

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.
