A camper wants to know the width of a river. From point A, he walks downstream 60 feet to point B and sights a canoe across the

Anarel [89]

<h2>Hello!</h2>

The answer is:

The correct option is:

D. 40 feet.

<h2>Why?</h2>

To solve the problem and calculate the width of the river, we need to assume that the distance from A to B and the angle formed between that distance and the distance from A to the other point (C) is equal to 90°, meaning that we are working with a right triangle, also, we need to use the given angle which is equal to 34°. So, to solve the problem we can use the following trigonometric relation:

$Tan\alpha =\frac{Opposite}{Adjacent}$

Where,

alpha is the given angle, 34°

Adjacent is the distance from A to B, which is equal to 60 feet.

Opposite is the distance from A to C which is also equal to the width of the river.

So, substituting and calculating we have:

$Tan(34\°) =\frac{Width}{60ft}$

$Width=60ft*Tan(34\°)=60ft*0.67=40.2ft=40ft$

Hence, we have that the correct option is:

D. 40 feet.

Have a nice day!

From past experience, the organization knows that about 20% of all potential donors will agree to give something if contacted by

Veronika [31]

Answer:

Total number of donor who will give first $ 100 = 100 people

Step-by-step explanation:

Given that:

Total percentage of people who donate when contact by phone 20%

Percentage of donating people who will give $100 or more = 5% = 0.05

Total number of donor who will give first $ 100 can be calculated as

calculate the percentage of donor who will give first $ 100

$P(X) = 0.05\times 0.20 = 0.01\ percent$

$\mu_x = \frac{1}{0.01}$

so, total number of the donor who will give first $ 100 = 100 people

Answers for the 2 boxes please:)

Answer:

(5,-5)

Step-by-step explanation:

<u>Eliminate</u><u> </u><u>y-term</u>

$(2x + 5x) + ( - 3y + 3y) = 25 + 10 \\ 7x = 35 \\ x = \frac{35}{7} \\ x = 5$

We can eliminate x-term but for this system of equations, eliminating y-term is faster.

<u>Substitute</u><u> </u><u>x</u><u> </u><u>=</u><u> </u><u>5</u><u> </u><u>in</u><u> </u><u>any</u><u> </u><u>given</u><u> </u><u>equations</u><u>.</u>

I will choose to substitute in the first equation.

$2x - 3y = 25 \\ 2(5) - 3y = 25 \\ 10 - 3y = 25 \\ 10 - 25 = 3y \\ - 1 5 = 3y \\ 3y = - 15 \\ y = - 5$

<u>Answer</u><u> </u><u>Check</u>

Substitute both x-value and y-value in any given equations

$2x - 3y = 25 \\ 2(5) - 3( - 5) = 25 \\ 10 + 15 = 25 \\ 25 = 25$

The equation is true. (<em>It</em><em> </em><em>is</em><em> </em><em>better</em><em> </em><em>to</em><em> </em><em>check</em><em> </em><em>both</em><em> </em><em>the</em><em> </em><em>answer</em><em> </em><em>for</em><em> </em><em>both</em><em> </em>equation.)

Thus the answer is (5,-5)
