At the zoo, for every 6 adult camels, there are 5 baby camels. There are a total of 44 adult and baby camels at the zoo.
lesya [120]

Using proportions, it is found that the table is completed as follows:

                         Original Ratio Number in the zoo

Baby camels     5                     20

Adult camels     6                     24

Total camels     11                     44

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

At the zoo, for every 6 adult camels, there are 5 baby camels, hence, out of 11 camels, 5 are baby and 6 are adult.

Thus, out of 44 camels, we have that:

  • 44/11 x 5 = 20, hence there are 20 baby camels.
  • 44/11 x 6 = 24, hence there are 24 adult camels.

The table is:

                         Original Ratio Number in the zoo

Baby camels     5                     20

Adult camels     6                     24

Total camels     11                     44

What is the sum of the EXTERIOR angles of an octagon?
navik [9.2K]

Answer:

A rule of polygons is that the sum of the exterior angles always equals 360 degrees. Since it is a regular octagon, so each of the interior angles of octagon are equal. ((n-2)*180)/n where n is the number of sides of the polygon.for example in case n=8 for an octagon, so we get:

((8-2)*180)/8 => (6*180)/8 => 1080/8 = 135 degrees. This means that each interior angle of the regular octagon is equal to 135 degrees.  

Each exterior angle is the supplementary angle to the interior angle at the vertex of the polygon, so in this case each exterior angle is equal to 45 degrees. (180 - 135 = 45). Remember that supplementary angles add up to 180 degrees.  

And since there are 8 exterior angles, we multiply 45 degrees * 8 and we get 360 degrees.

This technique works for every polygon, as long as you are asked to take one exterior angle per vertex.

Graph these equations: x+2y=6, y=-1/2x+4 How many solutions does the system of equations have?
inysia [295]

Answer:

The system has no solution

Step-by-step explanation:

we have

x+2y=6

Isolate the variable y

2y=-x+6

Divide by 2 both sides

y=-\frac{x}{2}+3 ---> equation A

y=-\frac{x}{2}+4 ---> equation B

Compare the equations

Equation A and equation B have the same slope and different y-intercept

Remember that

If two lines have the same slope, then the lines are parallel

The solution of the system is the intersection point both graphs

In this problem, the lines don't intersect, therefore, the system has no solution

using a graphing tool
