Answer:

This problem is a great systems of equations problem--you have two different variables: song size and number of songs.

Let's call the number of standard version downloads (S) and the high quality downloads (H).

You can make two statements:

For number of songs downloaded: S + H = 910

For download size: 2.8(S) + 4.4(H) = 3044.

S will be the same number in both equations and H will be the same number in both equations, so to find S, we can rearrange the first statement to H = 910 - S, then substitute or plug in (910 - S) wherever you see an H in the second equation so that you have only S's in your equation. Should look like this:

2.8(S) + 4.4(910 - S) = 3044

2.8S + 4004 - 4.4S = 3044

-1.6S = -960

s = 600

Your question only asks for the standard version downloads, but to help you out in future Systems situations-

You can also solve for H once you have S by plugging it into either of your equations like this:

600 + H = 910

-600

H=310

Answer:

V= 18.75 cm^3

Step-by-step explanation:

Answer: The answer is 39 square feet.

Step-by-step explanation:

By saying square feet it's indicated that you mean the area of this irregular figure.

To do this you can break apart the shape into two pieces.

The first 11 x 3 rectangle then the 2 x 3 rectangle.

Next, you can find the area to be 33 square feet and 6 square feet. respectively, afterward, you add the areas together to find the area of the figure, which is 39 square feet.

Answer:

12.73 Degrees

Step-by-step explanation:

I'm going to assume some things. The height of the truck is not changing, i.e. the the distance and length of the ramp is but the height stays the same.

We draw our right triangle, see photo

We really only care about finding out what side a is so

[tex]c = \frac{a}{ \sin(x) } [/tex]

Note: Let x = A

[tex]12 = \frac{a}{ \sin(36) } [/tex]

[tex]12 \sin(36) = a \\ a = 7.05342302750[/tex]

[tex] \sin(x) = ( \frac{opp}{hyp} ) \\ \sin(x) = ( \frac{7.05342302750}{12} ) \\ = 35.9999 \: degrees[/tex]

So, since I stated that height did not change, same process just using 32 for the hypotenuse.

[tex] \sin(x) = ( \frac{opp}{hyp} ) \\ \sin(x) = ( \frac{7.05342302750}{32} ) \\ = 12.73367164 \: \: degrees[/tex]

Answer:

The area of the triangular section is 12 square units. The area of the entire figure is  60  square units.

Step-by-step explanation:

The area of the triangular section is 12 square units and the area of the entire figure is 60 square units

The dimension of the triangular section is:

Base = 12 - 6 = 6 units

Height = 4 units

So, the area is:

Area = 0.5 * Base * Height

This gives

Area = 0.5 * 6* 4

Area = 12 square units

The area of the entire figure is then calculated as;

Area = Triangle + Rectangle

This gives

Area = 12 + 12 * 4

Evaluate

Area = 60

Hence, the area of the triangular section is 12 square units and the area of the entire figure is 60 square units

Answer:

Line 1: zero

Line 2: negative

Line 3: undefined

Line 4: positive

Step-by-step explanation:

Line 1 => slope is horizontal. The slope of horizontal lines are always equal to 0. Therefore, the slope of line 1 is zero.

Line 2 => the line slants downwards form our left to the right, this implies there is a decline or increase. Thus, the slope would be negative.

Line 3 => the line of a vertical line is always undefined. Line 3 slope is therefore undefined.

Line 4 => the slope slants upwards from our left to the right. This indicates a rising slope or an increase. Therefore, the slope of line 4 is positive.

Answer:

Option D

Step-by-step explanation:

We have that:

csc(x) = 1/sin(x)

Then:

csc(  tan(√(17)/8)^-1 )

To use the inverse tangent function, you can go to the "inv" button in your calculator, and then use go to the "tan" button.

This is equal to:

= csc( 27.26°)

= csc(27.26°)

= 1/sin(27.26°) = 2.18

And we know that:

(9*√17)/17 = 9/√17 = 2.18

Then the correct option is D.
