Answer:

$76.51

Step-by-step explanation:

The price after discounting is (1.00 - .35)($110), or 0.65($110) = $71.50.

The price after 7% sales tax has been added in is

(1.00 + 0.07)($71.50) = $76.51.

A radioactive substance decays at a rate of 25% every 10 years. Which equation represents the amount of the substance (S) remain
Lelechka [254]

Answer:

y = 100 * (0.75)^{30

Step-by-step explanation:

Given

a =100 --- Initial Amount

r= 25\% every 10 years

Required

The remaining amount after 300 years

To do this, we make use of:

y = a(1 - r)^T

Where

r = decay rate

T = the period of decay

In 300 years, there are 30 periods of 10 years.

i.e.

T = \frac{300}{10}

T = 30

y = a(1 - r)^T

y = 100 * (1 - 25\%)^{30

y = 100 * (1 - 0.25)^{30

y = 100 * (0.75)^{30

Both passages base their arguments on the unstated
Aleksandr-060686 [28]

The correct answer is option c) human cloning is a genuine possibility in the future.

Both passages base their arguments on the unstated assumption that human cloning is a genuine possibility in the future.

Both chapters describe cloning as if it is a foregone conclusion; as if it will occur in the near future. This is the implicit assumption in both paragraphs.

What is human cloning?

Human cloning is the process of creating a genetically identical replica of a human (or clone).

The phrase is most commonly used to refer to artificial human cloning, or the replication of human cells and tissue. It does not relate to identical twins being conceived and delivered naturally.

The prospect of human cloning has sparked debate. Because of these ethical considerations, numerous countries have passed laws prohibiting human cloning.

Therapeutic cloning and reproductive cloning are the two most widely discussed kinds of human cloning. Therapeutic cloning would include cloning human cells for use in medicine and transplantation.

An observer on top of a 50-foot tall lighthouse sees a boat at a 7° angle of depression. To the nearest foot, how far is the boa
Yuri [45]

Answer:

407.22 foot is the boat from the base of the lighthouse

Step-by-step explanation:

Given the statement: An observer on top of a 50-foot tall lighthouse sees a boat at a 7° angle of depression.

Let x foot be the distance of the object(boat) from the base of the lighthouse

Angle of depression = 7^{\circ}

\angle CAB = \angle DCA = 7^{\circ}       [Alternate angle]

In triangle CAB:

To find AB = x foot.

Using tangent ratio:

\tan (\theta) = \frac{Opposite side}{Adjacent Base}

\tan (\angle CAB) = \frac{BC}{AB}

Here, BC = 50 foot and \angle CAB =7^{\circ}

then;

\tan (7^{\circ}) = \frac{50}{x}

or

x = \frac{50}{\tan 7^{\circ}}

x = \frac{50}{0.1227845609}

Simplify:

AB = x = 407.217321 foot

Therefore, the boat from the base of the light house is, 407.22'
