Solve the system of equations using the elimination method and enter the value of y
4x - 5y = -9
- 4x + y = -7

Answers

Answer:

y = 4; x = 11/4

Step-by-step explanation:

4x - 5y = -9

-4x + y = -7

Add the two equations to eliminate x:

-4y = -16

-4y/-4 = -16/-4

y = 4

Plug in y for x

4x - 5y = -9

4x - 5(4) = -9

4x - 20 = -9

4x = -9 + 20

4x = 11

4x/4 = 11/4

x = 11/4

Each interior angle of a regular polygon = 140 deg. So each exterior angle of the regular polygon = 180-140 = 40 deg. Hence the regular polygon has 360/40 = 9 sides.

(a) Mary and Cynthia were building a cone-shaped sand castle. After some time, the diameter of
the sand shaped cone was 14 in. and the height was 15 in. What is the appoximate volume of the
sand cone rounded to the nearest tenth? (Show work!!) PLEASE HELP!

Answers

Answer:

[tex]\displaystyle V\approx 769.7\text{ in}^3[/tex]

Step-by-step explanation:

We are given that the diameter of the sand-shaped cone is 14 inches, and the height is 15 inches.

The volume for a cone is given by:

[tex]\displaystyle V=\frac{1}{3}\pi r^2h[/tex]

Where r is the radius and h is the height.

Since the diameter is 14, the radius is 7.

And we are given that the height is 15.

Therefore, the volume will be:

[tex]\displaystyle V=\frac{1}{3}\pi (7)^2(15)[/tex]

Use a calculator:

[tex]\displaystyle V\approx 769.7\text{ in}^3[/tex]

The volume of the cone is approximately 769.7 cubic inches.

A group of five students have a mean test score of "34.2." Another student has a score of 50. What is the mean average of all "six" students?

Answers

Answer:

The mean average of all "six" students is 36.83.

Step-by-step explanation:

Mean:

The mean is the sum of all scores divided by the number of scores.

A group of five students have a mean test score of "34.2." Another student has a score of 50.

This means that the sum is given by:

[tex]S = 5*34.2 + 50 = 171 + 50 = 221[/tex]

What is the mean average of all "six" students?

Sum of 6 students is 221. So

[tex]M = \frac{221}{6} = 36.83[/tex]

The mean average of all "six" students is 36.83.
