Answer:

m<CDE = 50°

Step-by-step explanation:

Recall: when an angle is formed outside a circle by two tangents, the angle formed = ½(the difference between the measures of the intercepted arcs), based on the outside angles theorem.

This implies that:

m<CDE = ½(Arc CBE - Arc CE)

Arc CE = 130°

Arc CBE = 360° - 130° = 230°

Plug in the values

m<CDE = ½(230 - 130)

m<CDE = ½(100)

m<CDE = 50°

The answer would be A. When using Cramer's Rule to solve a system of equations, if the determinant of the coefficient matrix equals zero and neither numerator determinant is zero, then the system has infinite solutions. It would be hard finding this answer when we use the Cramer's Rule so instead we use the Gauss Elimination. Considering the equations:

x + y = 3 and <span>2x + 2y = 6
Determinant of the equations are </span>
<span>| 1 1 | </span>
<span>| 2 2 | = 0
</span>
the numerator determinants would be
<span>| 3 1 | . .| 1 3 | </span>
<span>| 6 2 | = | 2 6 | = 0.
Executing Gauss Elimination, any two numbers, whose sum is 3, would satisfy the given system. F</span>or instance (3, 0), <span>(2, 1) and (4, -1). Therefore, it would have infinitely many solutions. </span>

Answer:

6.04 inches.

Step-by-step explanation:

Corbin want's to make a model, in which every 100 feet would be shown by 1 inch.

The monument is 604 feet in height.

Divide 604 with 100:

604/100 = 6.04

The height of Corbin's model would thereby be 6.04 inches.

What number must be added to 15,-6, and 12 to have a mean of 5? Explain.
Genrish500 [490]

You need to add a -1

We can find this by setting up the equation like so

x + (-6) + 12 + 15 / 4 = 5

x + 21 = 20

x = 20 -21

x = -1

Now if we insert -1 where x is located in the equation, you will get a means of 5

multiply width times the height to get the rectangle area

5 x 7 = 35 units squared

I may be wrong but I think you may be over complicating it its okay I do that a lot too
