Answer:

The percent of increase from 6 to 9 is 50%

Step-by-step explanation:

Percentages

To calculate the percentage increase:

Work out the difference (increase) between the two numbers you are comparing.

Increase = New Number - Original Number.

Divide the increase by the original number and multiply the answer by 100.

We are required to find the percent increase from 6 to 9. Here: New number=9, Original number = 6

Increase = 9 - 6 = 3

Divide 3 by 6 and multiply the answer by 100:

3 / 6 * 100 = 50%

The percent of increase from 6 to 9 is 50%

36, ___, ___, 32/3 is a geometric sequence, with some terms missing. First, please solve for "r", the common ratio between each

Nikitich [7]

Answer:

The geometric sequence is

36,24,16, $\frac{32}3$ ,.......

Step-by-step explanation:

The first term of the g.s is 36.

The 4th term of the given sequence is $\frac{32}{3}$ .

The $n^{th}$ term of the geometric sequence is

$T_n=ar^{n-1}$

Where a is the first term of the geometric sequence and r is the geometric sequence.

Then 4th term of the sequence is

$T_4=ar^{4-1}$

$\Rightarrow \frac{32}3=36r^3$

$\Rightarrow r^3=\frac{32}{3\times 36}$

$\Rightarrow r=\sqrt[3]{ \frac{8}{27}}$

$\Rightarrow r=\frac{2}{3}$

Then, second term of the sequence $=36\times( \frac 23)^{2-1}$

$=36\times \frac 23$

=24

The third term of the sequence is $=36\times( \frac 23)^{3-1}$

$=36\times( \frac 23)^2$

=16

The geometric sequence is

36,24,16, $\frac{32}3$ ,.......

8% of what amount is birr 60? A. Birr 480 B. Birr 750 C. Birr 800 D. Birr 520

Rzqust [24]

Answer:

B. Birr 750

Step-by-step explanation:

8% * 480 = 38.4

8% * 750 = 60

8% * 800 = 64

8% * 520 = 41.6

Therefore, 8% of Birr 750 is Birr 60.

Which of the following statements about an ellipse is NOT true?

jeyben [28]

Answer: (b) The focus of an ellipse is always located precisely at the center of the ellipse.

Step-by-step explanation:

An ellipse is defined as "a closed curve with two axes of symmetry (major axis and minor axis) that results in cutting the surface of a cone by an oblique plane to the axis of symmetry with an angle greater than that of the generatrix with respect to the axis of revolution". That is why the ellipse is considered a conic figure.

To understand it better: an ellipse has two points on its major axis that are equidistant from the center , which are called foci, being this distance constant. In addition, the eccentricity allows to know how far the foci are from the center of the ellipse.

Therefore, the statement that indicates an ellipse has only one focus located precisely at the center is incorrect.
