Answer:

Pop/rock = 17 million

Urban Latin= 2 million

Tropical = 4 million

Step-by-step explanation:

Let the pop/rock be denoted by P

Urban be denoted by U

And T represents tropical.

From the first statement

"total revenues from digital sales of pop/rock, tropical (salsa/merengue/cumbia/bachata), and urban (reggaeton) Latin music in a certain country amounted to $23 "

We can deduct that

P + T +U = 23000000.......eqn(I)

From the second statement

"Tropical music brought in twice as much as urban music"

We can say T = 2U ......eqn(II)

And P-(T+U)=11000000

P- T-U= 11000000...... eqn(III)

Putting equation 2 in both equations we have

P + (2U)+ U = 23000000

P+ 3U = 23000000......eqn iv

Then putting

P - (2U)-U = 23000000

P - 3U= 23000000.......eqn v

Combining eqn Iv and v

P+ 3U = 23000000......eqn iv

P - 3U= 11000000.......eqn v

Solving simultaneously using elimination i.e adding the 2 equations

2P= 34000000

P= 17000000

Substituting P to the first equation

17000000+3U = 23000000

3U = 23000000-17000000

3U = 6000000

U = 2000000

And since T = 2U

T= 2* 2000000

T= 4000000.

The price of a cup coffee was 2.40 yesterday. Today, the price fell to 2.15 find the percentage decrease. Round the answer to th
irakobra [83]
ANSWER

The percentage decrease is 10.4%.

EXPLANATION

To calculate percentage decrease, use the formula,

Percentage decrease

= \frac{new \: price - old \: price}{old \: price} \times 100\%

Yesterday the price of coffee was 2.40. This is the old price.

Today the price is 2.15. This is the new price.

= \frac{2.15 - 2.40}{2.40} \times 100\%

= \frac{ - 0.25}{2.40} \times 100\%

= - 0. 10416667 \times 100\%

= - 10.416667\%

To the nearest tenth, we have:

- 10.4\%

Therefore the percentage decrease is 10.4%.

A portion of a map with cities a and b is shown.The map uses a scale of 1 inch to 30 miles. A new map has a scale of 2 inches=15
Alina [70]

Answer:

22.5miles

Step-by-step explanation:

For Map 1;

1 inches = 30miles

For Map 2:

2 inches = 15miles

1 inches = x

2x = 1 *15

x = 15/2

x = 7.5miles

This means that 1 inch represents 7.5miles on Map 2'

The distance between the two cities in miles = 30miles - 7.5miles

The distance between the two cities (in miles) = 22.5miles
