A whale costs $14700 and depreciates in value by 8% per year. When will the whale be worth $100
sammy [17]

Answer:

x = 60

Step-by-step explanation:

The question is asking

$14,700 * (1 - 8%)^x = $100

$14,700 * (1 - 0.08)^x = $100

$14,700 * (0.92)^x = $100

(0.92)^x = $100/$14,700

log(0.92^x) = log($100/$14,700)

x * log(0.92) = log(0.0068027)

x = log(0.0068027)/log(0.92)

x = 59.85

Since this question is asking in terms of years, we always round up (in this case to 60), as it won't fully be worth $100 by the beginning of the 59th year.

a right triangle has a height of 20 centimeters and a base of 10 centimeters.what is the area of the triangle?
viktelen [127]

Answer:

<u><em>The </em></u><u><em>area of the right triangle</em></u><u><em> is </em></u><u><em>100 centimeters squared.</em></u>

Step-by-step explanation:

<u><em>The </em></u><u><em>formula for the area of a right triangle is:</em></u>

Area = \frac{a*b}{2}

<u><em>Area = (a*b) / 2</em></u>

<u><em>The height of a triangle is represented by a. The base is represented by b.</em></u>

<u><em>Knowing this, we can use what they give us for the values, by </em></u><u><em>plugging them into the formula</em></u><u><em>.</em></u>

<u><em>a is 20 cenimeters</em></u>

<u><em>b is 10 centimeters</em></u>

<u><em>Therefore :</em></u>

Area = \frac{200}{2}

Area = 100

<u><em>So, the </em></u><u><em>area of the right triangle</em></u><u><em> is</em></u><u><em> 100 centimeters squared.</em></u>
