Find the geometric mean of the pair numbers 6 and 10

Mathematics
1 answer:
inn [45]2 years ago
3 0

Answer:

The geometric mean between 6 and 10 will be:

G.M=2\sqrt{15}

Step-by-step explanation:

We know that the geometric mean between the two numbers 'a' and 'b' is defined as:

G.M=\sqrt{a\times b}

Now, let us determine the geometric mean between 6 and 10

  • a = 6
  • b = 10

Using the formula

G.M=\sqrt{a\times b}

G.M=\sqrt{6\times 10}

        =\sqrt{60}

        =\:\sqrt{4\times 15}

        =2\sqrt{15}

 Therefore, the geometric mean between 6 and 10 will be:

G.M=2\sqrt{15}

Which of the following is an example of direct variation?
LekaFEV [45]

Answer:

C

Step-by-step explanation:

Direct variation is a special case of first order equations; in both cases, the input is multiplied by a constant which we call the "slope" or "constant of variation."  However, no direct variation equation includes a constant ("y-intercept").  So, if a given equation does have a y-intersect, that equation does not represent direct variation; if it does NOT have a y-intercept, that equation represents direct variation.

A)  involves a constant term, -2; NOT direct variation

B)  involves a constant term, 10; NOT direct variation

C)   Here 3y = x, or y = x/3, involves no constant term, so Does represent direct variation

D)  involves a constant term -3; NOT direct variation

Answer:

8 is the length of JB

Step-by-step explanation:

<u>Key skills needed: Equations, Congruence</u>

1) We need to find out an equation to make based on the lengths that are given. ΔJMB is congruent to ΔKMB because of Side-Angle-Side:

  • JB is congruent to BK
  • Angle MBK would be a right angle, since it is supplementary to the right angle JBM. Since both are right angles they are congruent.
  • Both triangles have the side BM. Using the reflexive property, BM is congruent to itself, so there you go --> Side-Angle-Side

2) Now since both triangles are congruent, we can make the equation that the length of JM is congruent to the length of MK, using the fact that: If triangles are congruent, then corresponding parts are congruent.

3) This means that 16x -24 = 4x

Subtract 16x from both sides : -24 = -12x

Divide by -12 on both sides and get x = 2

4) Substitute x into the length of JB (16x-24)

16(2)-24 = 32-24 = 8

5) Therefore, the length of JB is 8

Kelly has 4 times as many songs on her music player as Lou. Tiffany has 6 times as many songs on her music player as Lou. Altoge
slava [35]
Let the number of songs owned by Lou  be  =  x.

Kelly has 4 times as many songs as Lou    =  4x

Tiffany has 6 times as many songs as Lou  = 6x

They all have total of 682 songs

=    x + 4x + 6x = 682
           11x  = 682
               x  = 682 / 11 .           Use your calculator.
               x =62.

How many songs Kelly has  = 4x = 4*62 =  248 songs.
Kelly = 248 songs.
