The cost of a cd after 6 year is =$ 15.12

Step-by-step explanation:

The present cost of the cd is $11.95 and inflation rate 4%

P = $11.95 , r = 4% and n = 6 years

The cost of a cd after 6 year is = $P (1+\frac{r}{100})^n$

=$ $11.95(1+\frac{4}{100})^6$

=$ 15.12

Answer: x = 40

Step-by-step explanation:

3x + x + 20 = 180 same side (consecutive) interior angles

4x + 20 = 180

4x = 160

x = 40

****************************************************************************

Answer: x = 24

Step-by-step explanation:

6x - 24 + 2x + 12 = 180 linear pair (supplementary angles)

8x - 12 = 180

8x = 192

x = 24

****************************************************************************

Answer: x = 16

Step-by-step explanation:

base angles of an isosceles triangle are congruent

2(2x + 15) + 6x - 10 = 180 triangle sum theorem

4x + 30 + 6x - 10 = 180

10x + 20 = 180

10x = 160

x = 16

****************************************************************************

Let ∠1 and ∠2 represent the exterior angles in the diagram and "x" represent the same side (consecutive) interior angle with ∠1.

Then m∠1 + x = 180 same side interior angle theorem

and m∠2 + x = 180 linear pairs are supplementary

m∠1 + x = m∠2 + x transitive property

m∠1 = m∠2 subtraction property of equality

∠1 ≈ ∠2 definition of congruency

Suppose that y varies inversely with x. Use the information to find k, and then choose the equation of variation. X= 2.5 when y=

puteri [66]

Answer:constant of variation(k) is, 250.

Step-by-step explanation:

The inverse variation says that:

then, the equation is in the form of :

....[1] where, k is the constant of variation

As per the statement:

Suppose that y varies inversely with x.

then,

by definition of inverse variation we have;

When x = 2.5 and y = 100 then

Substitute these in [1] we have;

Multiply 2.5 both sides we have;

k = 250

⇒

Therefore, the constant of variation is, 250 and the equation we get
