Answer:

Step-by-step explanation:

This is a special right triangle: 5, 12, 13

Or you can solve using the Pythagorean Theorem (a^2+b^2=c^)

--> 13^2-12^2=b^2

-->169-144=b^2

-->25=b^2

b=5

Answer:

solution

here

hypotenuse (h)=13

perpendicular(p)=12

now,

h^2=p^2+b^2

13^2=12^2+b^2

169=144+b^2

169-144=b^2

b^2=25

b=5

Answer:

880 high-quality version

Step-by-step explanation:

I think the below is your full question:

A Web music store offers two versions of a popular song. The size of the standard version is 2.1megabytes (MB). The size of the high-quality version is 4.5 MB. Yesterday, there were 1290 downloads of the song, for a total download size of 4821 MB. How many downloads of the high-quality version were there?

Here is my answer:

Let x is the number of high-quality version

So the number of standard version= 1290 - x

We also know: total download size of 4821 MB. which means:

4.5x + 2.1(1290-x) = 4821

<=> 4.5x+2709-2.1x=4821

<=> 2.4x=2112

<=> x=880

So there were 880 high-quality version

Caitlin is designing a railing for a set of stairs. The railing will begin at a height of 36 inches and follow the slant of the

ollegr [7]

The function which can represent the height, y according to the horizontal distance, x is; Choice A; y = –3/4x + 36.

Which function can represent the height, y, according to the horizontal distance x, from the top of the stairs?

According to the task content; The railing will begin at a height of 36 inches and follow the slant of the stairs. On this note, it follows that the y-intercept of the function is 36.

Additionally, since the railings decreases 9 inches for every 12 horizontal inches, it follows that the slope, m = -9/12 = -3/4.

On this note, the required function is; A.y = –3/4x + 36
