janet is comparing prices of bottled water. one bottle of water costs $1.92 and contains 12 ounces. another bottle of water cost
AnnyKZ [126]

Bottle 1 = $1.92 & 12 ounces

Bottle 2 = $2.40 & 16 ounces

Bottle 1

If 12 ounces costs $1.92, to determine the price of 1 ounce we divide $1.92 by 12.

$1.92 ÷ 12 = $0.16 per ounce for bottle 1.

Bottle 2

If 16 ounces costs $2.40, to determine the price of 1 ounce we divide $2.40 by 16.

$2.40 ÷ 16 = $0.15 per ounce for bottle 2.

Therefore we can determine that Bottle 2 is cheaper per ounce than Bottle 1.

Happy Tuesday! Looking for some help with my geometry.
svetlana [45]

Answer:

Q1

  • cos 59° = x/16
  • x = 16 cos 59°
  • x = 8.24

Q2

BC is given 23 mi

<u>Maybe AB is needed</u>

  • AB = √34² + 23² = 41 (rounded)

Q3

  • BC² = AB² - AC²
  • BC = √(37² - 12²) = 35

Q4

Let the angle is x

  • cos x = 19/20
  • x = arccos (19/20)
  • x = 18.2° (rounded)

Q5

See attached

Added point D and segments AD and DC to help with calculation

  • BC² = BD² + DC² = (AB + AD)² + DC²

<u>Find the length of added red segments</u>

  • AD = AC cos 65° = 14 cos 65° = 5.9
  • DC = AC sin 65° = 14 sin 65° = 12.7

<u>Now we can find the value of BC</u>

  • BC² = (19 + 5.9)² + 12.7²
  • BC = √781.3
  • BC = 28.0 yd

<em>All calculations are rounded</em>
