Answer:

Explained below

Step-by-step explanation:

We are told that; Line CA = Line CD

Thus, it means that;

∠ACD = ∠BCD

Line CE is equal in both triangles. Thus,

Line CE = Line CE

This then implies that;

ΔACD = ΔBCD

Finally, it means that;

Line AD = Line BD

Since Line AD = Line BD, it means the perpendicular line from point C touching D is a bisector of Line AB

Jessica is organizing a guided tour of the rain forest. The average profit per person that the touring company makes is given by

Allushta [10]

As a practical equation, this one doesn't make much sense -- why would the profit per person have a term proportional to the number of people? Let's just go with it.

$18x + \dfrac{35}{x}$

$= \dfrac{18x^2}{x} + \dfrac{35}{x}$

$= \dfrac{18x^2 + 35}{x}$

That's the answer to the first part.

35/x represents a portion of the profit that's 35/x per person, or a constant $35 per tour.

1400 dollars is placed in an account with an annual interest rate of 5.5%. to the nearest year, how long will it take for the ac

olga_2 [115]

It will take 19 years and 6 months for the account value to reach 2900 dollars

Step-by-step explanation:

Given

Principal amount = 1400 dollars

Rate = 5.5 %

Final value = A = 2900

We have to find t

So,

The formula for simple interest is:

$A = P(1+rt)$

Putting values

$2900 = 1400(1+0.055.t)\\\frac{2900}[1400} = 1+0.055t\\2.071 = 1+0.055t\\2.071-1=0.055t\\1.071 =0.055t$

Dividing both sides by 0.055

$\frac{0.055t}{0.055} = \frac{1.071}{0.055}\\t = 19.47\ years$

Rounding off to nearest tenth

19.5 years

Hence,

It will take 19 years and 6 months for the account value to reach 2900 dollars

Is this right and what's the answer for number 3?

Mumz [18]

That looks great! But say you chose number 2. You could say you organized it by multiplying single packs by the pieces of packs.
