The statement that describes the expression ( 5 x 3 - 12 ) x 8 is:

Subtract 12 from the product of 5 and 3, then multiply by 8.

Given,

( 5 x 3 - 12 ) x 8

We need to find the best statement that describes this expression.

Let A and B be any numbers.

Subtract:

= A - B

Multiply:

= A x B

Product:

= A x B

Difference:

= A - B

Find the statement that describes ( 5 x 3 - 12 ) x 8.

We have,

5 x 3 = 15

This is the product of 5 and 3.

5 x 3 - 12

This is the subtraction of 12 from the product of 5 and 3.

Or

The difference between the product of 5 and 3 and  12

(5 x 3 - 12 ) x 8

This is subtract 12 from the product of 5 and 3, then multiplying by 8.

Thus the statement that describes the expression ( 5 x 3 - 12 ) x 8 is:

Subtract 12 from the product of 5 and 3, then multiply by 8.

Answer:

90pi [tex]in^{3}[/tex] or about 282.74 [tex]in^{3}[/tex]

Step-by-step explanation:

Volume is found by base area times height (B*h).

6/2 = 3

3^2 = 9

B: 9pi

9pi*1- = 90pi [tex]in^{3}[/tex] or about 282.74 [tex]in^{3}[/tex]

Answer:

282.6 in³

Step-by-step explanation:

Radius = 6/2 = 3

Volume = pi × r² × h

3.14 × 3² × 10

282.6 in³

H = 20

VALUE OF H IS 20

WHEN YOU ADD 20 AND 20 IT WILL GIVE 40

The value of h using concept of missing angles is: h = 55

We know that the sum of angles on a straight line is 180 degrees.

Thus, the remaining two internal angles of the triangle are:

180 - 2h and 180 - 2h

We also know that the sum of angles in a triangle is 180 degrees. Thus:

180 - 2h + 180 - 2h + 40 = 180

400 - 4h = 180

4h = 400 - 180

4h = 220

h = 220/4

h = 55

Answer:10

Step-by-step explanation:

if a song costs $1.50 and a video is 2 times that amount of a song, then the video would cost $3. you have a balance of $60. you by 15 videos to start. i multiplied $3 by 15 to get the cost of the movies, witch is $45. after i got the cost of the movies i subtracted the $45 from the over all amount, i got 15. now to the songs. i have $15 to get music. 2 songs costs $3( 1.50+1.50= 3.00). 4 songs would cost $6. 8 songs would cost $12. after that i just added 1.50 until i hit a total of 15. so you can get 10 songs for $15

After buying 15 videos, you can purchase 10 songs with your $60 credit. Each video costs $3.00 and each song $1.50. After buying the 15 videos for $45, you have $15 left for songs.

The subject matter of this question falls under Mathematics, specifically operations involving money and elementary algebra. This kind of problem is typically encountered by middle school students, hence the grade level.

In order to answer the question, here's a step by step solution: First, we need to know the cost of downloading a video. Since each download of a video costs 2 times as much as the song download, and the song download costs $1.50, then the video download costs 2 * $1.50 = $3.00. If you plan to buy 15 videos, the total cost would be 15 videos * $3.00/video = $45.00.

Subtracting this amount from your $60 credit, you'll have $60 - $45 = $15 left. Given that the cost of a song download is $1.50, you can therefore purchase $15 / $1.50/song = 10 songs.

So, after buying 15 videos, you can still purchase 10 songs with your $60 credit.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Actually, the lesson is giving you wrong information. The exponential function written in the example does not work for the point (4, 24).

Here's another way to look at it.

Given

  two points: (x1, y1) and (x2, y2)

Solution

The exponential function can be written as ...

  y = (y1)(y2/y1)^((x -x1)/(x2 -x1))

Example

For the example points, the function would be ...

  y = (6)(24/6)^((x-2)/(4-2)) = 6·4^(x/2 -1) = (6/4)(4^(1/2))^x = (3/2)2^x

Check

  For x=2, y=(3/2)2^2 = 6. For x=4, y = (3/2)2^4 = 24.

You will notice that we figure out "b" and "a" as a part of the process of simplifying the equation. The equation would work perfectly well without simplification.

_____

1. Given points (2, 50) and (3, 250), the equation is ...

  f(x) = 50(250/50)^((x -2)/(3 -2)) = 50·5^(x -2) = (50/25)5^x

  f(x) = 2·5^x . . . b = 5; a = 2

__

2. Given points (1, 3) and (2, 9/2), the equation is ...

  f(x) = (3)(3/(9/2))^((x -1)/(2 -1)) = (3)(2/3)^(x -1) = (3/(2/3))(2/3)^x

  f(x) = (9/2)(2/3)^x . . . b = 2/3; a = 9/2

__

3. Given points (3, 32) and (4, 128), the equation is ...

  f(x) = (32)(128/32)^((x -3)/(4 -3)) = (32)4^(x -3) = (32/64)4^x

  f(x) = (1/2)4^x . . . b = 4; a = 1/2

_____

Additional comments

The usual rules of exponents are useful in this:

  a^(b+c) = (a^b)(a^c)

  a^(bc) = (a^b)^c

  a^-b = 1/a^b

Answer:240

Step-by-step explanation:

Given:

Given that O is the center of the circle.

AB is tangent to the circle.

The measure of ∠AOB is 68° and we know that the tangent meets the circle at 90°

We need to determine the measure of ∠ABO.

Measure of ∠ABO:

The measure of ∠ABO can be determined using the triangle sum property.

Applying the property, we have;

[tex]\angle ABO+\angle BAO+\angle AOB=180^{\circ}[/tex]

Substituting the values, we get;

[tex]\angle ABO+90^{\circ}+68^{\circ}=180^{\circ}[/tex]

Adding the values, we have;

[tex]\angle ABO+158^{\circ}=180^{\circ}[/tex]

Subtracting both sides by 158, we get;

[tex]\angle ABO=22^{\circ}[/tex]

Thus, the measure of ∠ABO is 22°

The equation for a vertical line passing through (-6,6) is x = -6. However, this line cannot be represented by a formula for a linear function in the form y = mx + b, as a vertical line has an undefined slope.

A vertical line in a coordinate plane, such as the one passing through point (-6,6), has an equation format of x = c where c represents a constant value. In this particular case, as the line passes through the x-coordinate of -6, the equation of the vertical line is x = -6.

As for creating a formula for a linear function whose graph is this given line, that is not possible. Linear functions can be represented by the slope-intercept form "y = mx + b" where m represents the slope and b is the y-intercept. However, a vertical line does not have a slope (it is considered undefined or infinite), and therefore can't be represented as a linear function in this form.

24x = 72

Divide each side by 24

24x/24 = 72/24

x =3

Answer:

x = 3

Step-by-step explanation:

6 (4x + 1) = 78

4x + 1 = 78 ÷ 6

4x + 1 = 13

4x = 13 - 1

4x = 12

x = 3

Answer:

y= -1\2x-4

Step-by-step explanation:

y=mx+c

perpinicular means you flip the slop and change the sign so the slope(m) become -1\2

y=-1\2x+c

since he gives you (8,-8) meaning x=8 and y= -8

we substitute

-8=(-1\2 x 8) +c

now we isolate c

-8+4=c

c=-4

the equation will be

y= -1\2x-4
