Sure the sin function is an odd function because sin (-Ф) = - sin (Ф)
Example: sin (- 30°) = - sin (30°) = -1/2

The taxi fare in Gotham City is $2.40 for the first 1/2 mile and additional mileage charged at the rate $0.20 for each additiona
Troyanec [42]
3.3 miles should be the answer
10 = 2.40 + .2x    - take 2.4 from both sides
7.6 = .2x              - take 2 from 7.6 for the tip
5.6 = .2x              - divide both sides by .2
28 = x
this means that you can pay the taxi drives an additional 28 times with the .20 cents fee and still have 2 dollars left over       
now multiply 28 by .1 miles which is 2.8 miles
add 2.8 miles to .5 miles which equals 3.3 miles

Tristan and Ronna are collecting clothes for a clothing drive. Ronna collected 3 times as many clothes as Tristan did. If Trista
Anni [7]

Ronna collected 12\frac{3}{4} bags of clothes

Step-by-step explanation:

Tristan and Ronna are collecting clothes for a clothing drive

  • Ronna collected 3 times as many clothes as Tristan
  • Tristan collected 4\frac{1}{4} bags

We need to find how many bags of clothes  Ronna collected

∵ Ronna collected 3 times as many clothes as Tristan did

- That means Ronna collected 3 × the amount that Tristan did

∵ Tristan collected 4\frac{1}{4} bags

- Multiply the amount of Tristan by 3 to find the amount of Ronna

∴ Ronna collected = 3 × 4\frac{1}{4}

Change the mixed number to improper fraction

∵ 4\frac{1}{4} = \frac{(4*4)+1}{4}=\frac{17}{4}

∴ Ronna collected = 3 × \frac{17}{4}

∴ Ronna collected = \frac{51}{4}

Change the improper fraction to mixed number by divide 51 by 4

∵ 51 ÷ 4 = 12 and reminder 3 (4 × 12 = 48 and 51 - 48 = 3)

∴ \frac{51}{3}=12\frac{3}{4}

∴ Ronna collected = 12\frac{3}{4} bags of clothes

Ronna collected 12\frac{3}{4} bags of clothes
