Answer:

You can buy 5 songs.

Step-by-step explanation:

First, you would divide 9 by 12 which is 0.83, assuming that each song costs 0.83 by itself you would just add 0.83 + 0.83 until you reach 4.15, the amount of times you added is the answer, which is 5 lolz

A cab in NYC charges you $1.25 a mile and a flat fee of $4 to ride in the cab. A cab in Chicago charges you $0.75 a mile but a f

Vikentia [17]

Answer:

After 4 miles driven by cab the amount would be same in both cities.

Step-by-step explanation:

Let the number of miles be 'x'.

Given:

In NYC

Flat fee of cab = $4

Per mile charge = $1.25

Total cab charges is equal to sum of Flat fee of cab and per mile charge multiplied by number of miles.

Framing in equation form we get;

Total cab charges in NYC = $4+1.25x$

In Chicago

Flat fee of cab = $6

Per mile charge = $0.75

Total cab charges is equal to sum of Flat fee of cab and per mile charge multiplied by number of miles.

Framing in equation form we get;

Total cab charges in Chicago = $6+0.75x$

Now we need to find number of miles driven so that the amount could same in both cities.

Total cab charges in NYC = Total cab charges in Chicago

$4+1.25x=6+0.75x$

Combining like terms we get;

$1.25x-0.75x=6-4\\\\0.5x=2$

using Division Property we will divide both side by 0.5 we get;

$\frac{0.5x}{0.5} =\frac{2}{0.5} \\\\x=4$

Hence After 4 miles driven by cab the amount would be same in both cities.

Mai, Clare, and Noah are making signs to advertise the school dance. It takes Mai 6 minutes to complete a sign, it takes Clare 8

Vaselesa [24]

Answer:

There is no question here, but suppose you want to find the number of signs they can make in half an hour, the answer is 14.

Step-by-step explanation:

Times it take to complete a sign.

Mai = 6 minutes

Clare = 8 minutes

Noah = 5 minutes.

Since they keep working for half an hour, which is 30 minutes. Suppose we want to find how many signs they can all make in that time, all we have to do is determine how many signs each person can make and then sum it.

Mai, who makes one every 6 minute, can make only 30/6 signs in 30 minutes. 30/6 = 5

Mai can make 5 signs in that time

Clare, who makes one every 8 minute, can make only 30/8 signs in 30 minutes. 30/8 = 3.75

She can only make 3 signs.

Noah, who makes one every 5 minute, can make only 30/5 signs in 30 minutes. 30/5 = 6

He can only make 6 signs.

In total, they can make 6 + 5 + 3 = 14 signs in half an hour.

A man measured his height and found 5.7 feet. However, after he carefully measured his height a second time, he found his real h

Lina20 [59]

Answer:

percentage error = 12.28%

Step-by-step explanation:

5 x 0.14 = 0.7

5 x 1.14 = 5.7

as increase is not the same as error decrease.

We use the same numbers 12.28% = 0.1228.

5.7 x 0.1228 = 0.69996 = 12.28%

5.7 - 0.69996 = 5.00004 foot. As decrease.

And find it is correct.

His error therefore was 12.28% out.

As we work the first numbers 5.7 and can only x by a number to see 5ft

We take 5.7 x 0.1228 and find 0.69996 when taken from 5.7 ft. is unmistakably 5 foot. (5.00004) ft.
