A Web music store offers two versions of a popular song. The size of the standard version is 2.1 megabytes (MB). The size of the

SashulF [63]

Answer:

There were 440 Standard version of songs downloaded in Web music store.

Step-by-step explanation:

Given,

Total number of songs downloaded = 1310

Total size of the downloaded songs = 4752 MB

Size of standard version of song = 2.1 MB

Size of high quality version of song = 4.4 MB

Solution,

Let the number of standard version of song be 'x'.

And also let the number of high quality version of song be 'y'.

Now, total number of songs is the sum of total number of standard version of song and total number of high quality version of song.

On framing the above sentence in equation form, we get;

$x+y=1310\ \ \ \ \ equation\ 1$

Now, Total size of the downloaded songs is the sum of total number of standard version of song multiplied with size of standard version of song and total number of high quality version of song multiplied with size of high quality version of song.

On framing the above sentence in equation form, we get;

$2.1x+4.4y=4752$

Multiplying with 10 on both side, we get;

$10(2.1x+4.4y)=4752\times10\\\\21x+44y=47520\ \ \ \ equation\ 2$

Now multiplying equation 1 by 21, we get;

$21(x+y)=1310\times21`\\\\21x+21y=27510\ \ \ \ equation\ 3$

Now subtract equation 3 from equation 2, we get;

$(21x+44y)-(21x+21y)=47520-27510\\\\21x+44y-21x-21y=20010\\\\23y=20010\\\\y=\frac{20010}{23}\\\\y=870$

On substituting the value of y in equation 1, we get the value of x;

$x+y=1310\\\\x+870=1310\\\\x=1310-870=440$

Hence There were 440 Standard version of songs downloaded in Web music store.

Select the correct answer. What is the domain of the function shown on the graph?

maw [93]

Answer:

B. negative infinity < x < positive infinity

Step-by-step explanation:

When a question asks for the domain of a function, it is asking for all possible x-values, so we can rule out choice A since there are clearly x-values greater than 1. This graph shows arrows pointing left and downward, indicating that the graph continues past what we can see. This tells us that even though the x-values look like they end at -10 and 2, they continue further, so we can also rule out option C and option D. After these eliminations, we are left with choice B, which is a way of writing "All real numbers," and is the domain for all exponential functions, including this one.

lmk if im incorrect about anything, hope this helps :)

Miss Green tells you that a right triangle has a hypotenuse of 13 and a leg of 5 she asked you to find the other leg of the tria

Natalka [10]

Answer:

The other leg of the triangle is 12.

Step-by-step explanation:

Given:

Hypotenuse of triangle is 13 and a leg(Leg1) is 5.

Let, the other leg of the triangle (Leg2) be $x$ .

Now, putting the formula:

$(Hypotenuse)^{2}=(Leg1)^{2}+(Leg2)^{2}$

⇒ $13^{2} =5^{2} +x^{2}$

⇒ $169=25+x^{2}$

⇒ $169-25=x^{2}$

⇒ $144=x^{2}$

Taking square root both sides

⇒ $12=x$

⇒ $x=12$ .

Therefore, the other leg of the triangle is 12.
