Fudgin [204]

9514 1404 393

Answer:

  $98.15

Step-by-step explanation:

2005 is 15 years after 1990. Using the formula we find ...

  c(15) = 63·1.03^15 ≈ 63·1.55797

  c(15) ≈ 98.152

An ounce of the chemical costs about $98.15 in 2005.

Pachacha [2.7K]
5x + 4y = 32 ⇒ 45x + 36y = 288
9x -  1y = 33 ⇒ <u>45x -    5y = 165</u>
                                    <u>41y</u> = <u>123</u>
                                     41      41
                                        y = 3
                            5x + 4(3) = 32
                              5x + 12 = 32
                               <u>    - 12  - 12</u>
                                      <u>5x</u> = <u>20</u>

Triangle S R Q is shown. Angle S R Q is a right angle. An altitude is drawn from point R to point T on side S Q to form a right
juin [17]

Answer:

RT = 12 units

Step-by-step explanation:

From the figure attached,

ΔSRQ is right triangle.

m∠R = 90°

An altitude has been constructed from point T to side SQ.

m∠RTQ = 90°

By applying geometric mean theorem in triangle SRQ,

\frac{\text{RT}}{\text{ST}}=\frac{\text{TQ}}{\text{RT}}

\frac{x}{9}=\frac{16}{x}

x² = 16 × 9

x² = 144

x = √144

x = 12

Therefore, length of altitude RT is 12 units.
