1. The sides of a triangle measure 6 inches, 10 inches, and 13 inches. What type of triangle is it?


A. right

B. scalene

C. isosceles

D. equilateral

Answer:

630 square meters.

Step-by-step explanation:

Given:

A triangular prism has an equilateral triangle base whose sides are 6 meters. The height of the prism is 35 meters, and the height of the base is 5.2 meters.

Question asked:

What is the lateral surface area of the prism?

Solution:

As we know:

[tex]Lateral\ surface\ area\ of\ the\ prism=Perimeter\ of\ the\ base\times height\ of\ the\ prism[/tex]

Perimeter of the equilateral triangle base = 6 + 6 + 6 = 18 meters

The height of the prism = 35 meters  

Lateral surface area of the prism = 18 [tex]\times[/tex] 35 = 630 square meters.

Thus, lateral surface area of the prism is 630 square meters.

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

20 times 4=80

21 times 4=84

Answer:240

Step-by-step explanation:

Answer:

D) 160

Step-by-step explanation:

20% × n = 32

20 /100 × n = 32

Multiplying both sides by 100 and dividing both sides by 20,

n = 32 ×  100 /20

n = 160

Answer:

D, 160

Step-by-step explanation:

Hello!

To find the answer to this question, we have can represent any number as "n."

Since 20% is the same as [tex]\frac{20}{100}[/tex], we have:

[tex]\frac{20}{100}[/tex] * n = 32

Now we multiply both sides by 100 to get rid of the fraction:

20n = 3200

And divide both sides by 20:

n = 160.

Thus, the answer is [tex]\boxed{160{\text{\:or\:D.}}}[/tex]

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.

Answer:

x=3

Step-by-step explanation:

6(4x+1) = 78

Distribute

24x+6 = 78

Subtract 6 from each side

24x +6-6 =78-6

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:

x = 9 and 12

Step-by-step explanation:

6/8 = x/12 = x/16

Simplify

3/4 = x/12 = x/16

Multiply 3/4 by 3/3 (does nothing but changes the number)

9/12 = x/12

x = 9

Multiply 3/4 by 4/4 ( also does nothing)

12/16 = x/16

x = 12

There is no values of X that will make the expression correct

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

Answer:4848.51

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
