Answer:

0.5s + 8 is the cost if he downloaded s songs

$28 is the cost for downloading 40 songs

Step-by-step explanation:

First, create an equation to represent the cost where s is the number of songs

Since it is 0.50 per song, the cost per song can be represented by 0.5s. Then, add 8 to this in the equation to represent the monthly fee.

Put this together:

0.5s + 8 is the cost if he downloaded s songs

Plug in 40 as s to find the cost for 40 songs downloaded:

0.5s + 8

0.5(40) + 8

20 + 8

= 28

So, the cost for downloading 40 songs is $28

Quantavius took a hiking with some friends.The friend started early and walked a while before stoping to each lunch.After lunch

kifflom [539]

Answer:

$7\frac{3}{8} \ miles$

Step-by-step explanation:

Given:

After lunch the friends walked 6 3/4 miles before arriving at the end of the trail.

The trail is 14 1/8 miles long.

Question asked:

How long did the friends walk before lunch ?

Solution:

Let the friends walk before lunch in miles = $x$

As total length of trail is given $14\frac{1}{8}\ miles$ , we can conclude:

Total length of trail = The friends walk before lunch in miles + The friends walk after lunch in miles

$14\frac{1}{8} =x+6\frac{3}{4} \\ \frac{14\times8+1}{8}=x+\frac{6\times4+3}{4} \\\frac{113}{8} =x+\frac{27}{4}$

Subtracting both side by $\frac{27}{4}$

$\frac{113}{8} -\frac{27}{4} =x+\frac{27}{4}-\frac{27}{4}$

Taking LCM of 4 and 8 ,we get 8

$\frac{113-54}{8} =x\\\\\frac{59}{8} =x\\\ \\7\frac{3}{8} = x$

Therefore, the friends walk before lunch is $7\frac{3}{8} \ miles$ .

ronaldo delivers the papers at the rate of 6 papers in 24 minutes. how much longer would it take him to deliver 56 papers than 4

UkoKoshka [18]

We are given

Ronaldo delivers the papers at the rate of 6 papers in 24 minutes

so, number of papers =6 in time =24 minutes

so, firstly we can find rate

rate = ( number of papers)/( time taken)

$r=\frac{6}{24} =\frac{1}{4}$

now, we can find times

Time for 56 papers:

we are given

number of papers =56

rate is

$r=\frac{1}{4}$

now, we can find time

$t_1=\frac{56}{r}$

$t_1=\frac{56}{\frac{1}{4}}$

$t_1=224min$

Time for 41 papers:

we are given

number of papers =41

rate is

$r=\frac{1}{4}$

now, we can find time

$t_2=\frac{41}{r}$

$t_2=\frac{41}{\frac{1}{4}}$

$t_2=164min$

now, we can find time difference

$t=t_1-t_2$

so, we can plug values

$t=224-164$

$t=60 min$ ..............Answer
