Match the amounts and tip or tax rates in the first column to the total costs in the second column.

gogolik [260]

Answer:

1. $132.24

2. $55.89

3. $1336.66

4. $258.19

5. $57.86

Step-by-step explanation:

Simply use this equation.

$\frac{InitialValue}{100} = \frac{x}{TaxPercentage}$

Substitute in our values, using No.1 as our example.

$\frac{123.01}{100} = \frac{x}{7.5}$

Cross multiply

922.575 = x100

Solve for x by dividing by 100.

x = 9.22575

Now add x to the initial value.

9.22575 + 123.01 = 132.23575

Round to the nearest hundredth for the answer.

$132.24

There are fourteen songs on your playlist. Eight of them are country and six are

maxonik [38]

Answer: 34.965%

Step-by-step explanation:

Number of ways of selecting 8 songs from 14 songs = = 14! / [ 8! × (14-8)! ]

= 14! / (8! × 6!)

= 3003

If you listended to exactly four country songs, then you should listen to four pop songs because you listened to 8 songs

Number of ways of selecting 4 country songs from total 8 country songs

= 8! / [ 4! × (8-4)! ]

= 8! / (4! × 4!)

= 70

Number of ways of selecting 4 pop songs from total 6 pop songs

= 6! / [ 4! × (6-4)! ]

= 6! / (4! × 2!)

= 15

Number of ways of playing 4 country songs and 4 pop songs in total 8 songs = 70 × 15

= 1050

So Probability that you listened to exactly four country songs =1050/3003

= 0.34965

= 34.965%

Find the value of x to the nearest tenth.

Anastasy [175]

Answer:

x = 9.4

Step-by-step explanation:

(see attached for reference on cosine rule)

by cosine rule

x² = 8² + 15² - 2(8)(15) cos 33°

x² = 64 + 225 - 201.281

x² = 87.719

x = √87.719

x = 9.366

x = 9.4 (nearest tenth)
