Step-by-step explanation:

<u>Step 1:  Answer the first question</u>

Find the perimeter:  P = (\pi *r)+d        But... let π be 3.14

P = (3.14 * \frac{27}{2}) + 27

P = 42.39 + 27

P = 69.39

Find the price:  $7.25 per foot

7.25 * 69.39

\503.0775

Answer:  \503.0775

<u>Step 2:  Answer the second question</u>

Find the amount traveled:  P = revolutions*\pi *d          But... let π be 3.14

P = 17 * 3.14 * 95

P = 53.38 * 95

P = 5071.1

Answer:  5071.1 feet

Answer:

1. $503.08

2. 5071

Step-by-step explanation:

1. Perimeter = (pi × r) + d

= (3.14 × 27/2) + 27

= 69.39

Cost: 69.39 × 7.25 = $503.0775

2. 17 × (pi × d)

17 × 3.14 × 95

5071.1 feet

Paraphin [41]

Answer:

Step-by-step explanation:

1). In ΔABC,

   For angle A as a reference angle,

   Opposite side of ∠A → BC

   Adjacent side of ∠A → AC

   Hypotenuse → AB

2). By using tangent ratio in ΔYWZ,

    tan(72°) = \frac{\text{Opposite side}}{\text{Adjacent side}}

    tan(72°) = \frac{12}{x}

    x = \frac{12}{\text{tan}(72)}

    x = 3.899

    x ≈ 3.9

3). By using sine rule in ΔKNM,

    tan(x°) = \frac{\text{Opposite side}}{\text{Hypotenuse}}

    tan(x) = \frac{20}{58}

    x = \text{tan}^{-1}(\frac{20}{58} )

    x = 19.03

    x ≈ 19.0°

4). By applying cosine ratio in ΔJKF,

    tan(70°) = \frac{\text{Opposite side}}{\text{Adjacent side}}

    tan(70) = \frac{60}{x}

    x = \frac{60}{\text{tan}(70)}

    x = 21.838

    x ≈ 21.8

disa [49]

Answer:

  26%

Step-by-step explanation:

Your 36 monthly payments will total ...

  36 × $205.10 = $7383.60

$5860 of that is the amount you borrowed. The remainder is the interest you pay:

  $7383.60 -5860 = $1,523.60

As a percentage of the original loan amount this is ...

  $1523.60/$5860 × 100% = 26%

You pay back 26% of the original loan amount in interest.
