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

This is a proportion. What is the value of X?
Verizon [17]

Answer:

x = 15 or x = - \frac{2}{5}

Step-by-step explanation:

Cross- multiplying gives

(14x + 6)(17x + 5) = 9x(27x + 11) ( expanding factors )

238x² + 172x + 30 = 243x² + 99x

rearrange into standard form : ax² + bx + c = 0

5x² - 73x - 30 = 0 ← in standard form

consider the factors of the product 5 × - 30 = - 150 which sum to the coefficient of the x-term (- 73 )

the factors are - 75 and + 2

Use these factors to split the middle term

5x² - 75x + 2x - 30 = 0 ( factor by grouping )

5x(x - 15) + 2(x - 15) = 0 ← take out the factor (x - 15)

(x - 15)(5x + 2) = 0

equate each factor to zero and solve for x

x - 15 = 0 ⇒ x = 15

5x + 2 = 0 ⇒ x = - \frac{2}{5}
