From the given scenario above, the value of the car after n years is given by the equation,
                          V(n) = V₁(1 - d)^n
Where V(n) is the value after n years, V₁ is the original value, d is the depreciation rate and n is the number of years. Substituting the known values,
                          V(n) = ($25,750)(1 - 0.2)^5
                                 = $8,437.76
Thus, the answer is the second choice.

One angle of the following triangle measures 2x. How many degrees does that angle
ella [17]

<u>Given</u><u> info</u><u>:</u><u>-</u> In triangle (∆)ABC , in which ∠A = 2x, ∠B = x+15° and ∠C = 2x + 10°. Then find the value of x , also find the measure of each angles of a triangle.

<u>Explanation</u><u>:</u><u>-</u>

Let the angles be 2x, x+15 and 2x+10 respectively.

∵ Sum of the three angles of a triangle is 180°

∴ ∠A + ∠B + ∠C = 180° [Sum of ∠s of a ∆=180°]

→2x + x+15 + 2x+10 = 180°

→ 2x + x + 2x + 15 + 10 = 180°

→ 3x + 2x + 15 + 10 = 180°

→ 5x + 15 + 10 = 180°

→ 5x + 25 = 180°

→ 5x = 180°-25

→ 5x = 155°

→ x = 155°÷5 = 155/5 = 31.

Now, finding the measure of each angles of a ∆ABC by putting the original value of “x”.

∴ ∠A = 2x = 2(31) = 62°

∠B = x+15 = 31 + 15 = 46°

∠C = 2x + 10 = 2(31) + 10 = 62 + 10 = 72°.

Sonja [21]

In three hours Miguel drew 2 cartoon cells . And since he keeps drawing at the same rate, therefore,

in one hour Miguel drew (2/3) cartoon cells .

Hence in 9 hours, Miguel drew (2/3)* 9 = 18/3=6 cartoon cells .

So the answer of the given question is 6 cartoon cells .
