Answer:

Step-by-step explanation:

Answer:

Let x be the number of songs downloaded.

Each song is $1.29; the total cost would be found by multiplying the cost by the number of songs, or 1.29x.

This cannot be more than 20, so we set this less than or equal to 20:

1.29x ≤ 20.

To solve this, we divide both sides by 1.29:

≤ ;

x ≤15.5.

We cannot download half of a song, so we round this down to 15 (although the number rounds up mathematically, he would not have enough money to download 16 songs). This means he can download at most 15 songs.

Step-by-step explanation:

if you want the sample response then here: If x represents the number of downloads, you can write the inequality 1.29x ≤ 20. Solving the inequality, you find that x is less than or equal to about 15.5. Since he can’t download part of a song, Joseph can download 15 or fewer songs.

Answer:

P(x < 149.6) = 0.11821

Step-by-step explanation:

We start by calculating the z-score of the parameter given

Mathematically,

z-score = (x-mean)/SD/√n

z-score = (149.6-152.8)/26.2/√94

z-score = -3.2/2.70

z-score = -1.18

So the probability we want to calculate is;

P( x < -1.18)

we can use the standard normal distribution table to get this

From the standard normal distribution table, this value is 0.11821

Answer:

2/5

Step-by-step explanation:

first select the line that is positive which is the purple one

slope = change in y / change in x

two clear points are (0,2) and (5,4)

so you do y2-y1 / x2-x1

=(4-2)/(5-0)

=2/5

so the slope is 2/5

Step-by-step explanation:

Using the area model and standard algorithm, we have:

                332   (tenths)

          ×       21  

                332

             664    

             6972   tenths = 697.2

              30      +      3      tenths

     1       300           32         332

    20     600           64         664

The last one   5x-3y=15   This is the same as  y= (5/3)x -5

Step-by-step explanation:

5x-3y=15

Move 5x to the right (becoming negative)

-3y = -5x +15

Divide everything by - 3

y= (5/3)x -5

y intersect= -5   ( line crosses y coordinate at -5)

Slope = 5/3      From -5  you start counting  (5 up,3 right,5 up,3 right....  OR    5 down,3 left,5 down,3 left........)

Answer:

The measure of angle Q'R'S' is 35°

Step-by-step explanation:

The given parameters are;

The measure of angle QRS = 35°

The transformation applied to triangle QRS = 90° clockwise rotation

For a 90° clockwise rotation, we have;

Coordinate of the preimage (x, y), coordinate of the image after rotation (y, -x)

Given that the distance, d, between points is given by √((x₂ - x₁)² + (y₂ - y₁)²), we have that the distance between points of the image will be given as follows;

d' =√((y₂ - y₁)² + ((-x₂) - (-x₁))²) = √((y₂ - y₁)² + (x₁ - x₂)²)

Whereby we have √((y₂ - y₁)² + (x₁ - x₂)²) = √((x₂ - x₁)² + (y₂ - y₁)²)

Therefore, d = d' and the length of the sides and measures of the angles in ∠QRS and ∠Q'R'S' will be equal and ∠Q'R'S' = ∠QRS = 35°.

Answer

I think 55 times

Step-by-step explanation:

13,200/1,200 = 11

5/1200 =  x/13,200

so if 1,200*11=13, 200 then 5*11= 55.

The total time the stadium runs the cable ad in order to reach this target is 11 days and this can be determined by using the unitary method.

Given :

The following steps can be used in order to determine the total times the stadium run the cable ad in order to reach this target:

Step 1 - The unitary method can be used in order to determine the total times the stadium runs the cable ad in order to reach this target.

Step 2 - According to the given data, running a cable TV ad 5 times daily for a week generated 1,200 ticket sales.

Step 3 - If running TV ad 5 times daily sales 1200 tickets then to sell 13200 tickets the total times the ad is running is:

[tex]=\dfrac{13200}{1200}\times 5[/tex]

= 55 times

Step 4 - Now, if 5 times ad running in one day then 55 times ad running in:

[tex]=\dfrac{55}{5}\times 1[/tex]

= 11 days

Step-by-step explanation:

I think cause you would do 3 by the second power so that would be 9 then 9 the the second power would be 81 so yeah good luck

Answer:

D is your correct answer

Step-by-step explanation:

Well first things first if we want to simplify with a base and an exponent we can use product of two powers with like bases.

-------------------------

Example/model of product of two powers with like bases:

x^m + n (adding the exponents)

-------------------------

If we add those two exponents you get 3^4. Then if you do 3 x 3 x 3 x 3 = ?

What do you get? You get 81. Hope this helpss! Good luck!!

Answer:

Step-by-step explanation:

We know that the angle of elevation is 8 degrees.

We know that the height of the opposite side of the angle is 3 feet.

We want to know the adjacent side (the side from the start of the ramp to the bottom of the opposite side)

We can do this with tangent

[tex]tan(8) = \frac{3}{adj} \\adj = \frac{3}{tan(8)} \\adj = 21.34611 feet[/tex]

The distance between the ramp and the door can be calculated using the principle of Pythagoras, Hence, the distance should be 21.34 feets

Using SOHCAHTOA :

Tanθ = Opposite / Adjacent

Tan(8°) = 3 / d

0.1405408 = 3 / d

0.1405408d = 3

Divide both sides by 0.1405408 to isolate d

0.1405408d / 0.1405408 = 3 / 0.1405408

d = 21.34 feets

Therefore, the distance of the ramp from the door should be 21.34 feets

Answer: Distributive Property

The term "distribution" is also used in place of "distributive"

This property says

x*(y+z) = x*y + x*z

We multiply the outer term x with each inner term (y and z). Then we add the results.

In this case,

x = 5

y = a

z = 3b

So,

5(a+3b) = 5*a + 5*3b = 5a+15b

Step-by-step explanation:

3x + 7y > 21

where:

x = number of field goals needed to win

y = number of touchdowns (plus extra point) needed to win

Since your team is 21 points behind and you want to win the game, not tie it, the number of field goals and touchdowns must result in a number higher than 21, not equal to or higher than.
