If the geometric mean of a and 34 is 6 sqrt(17) find the value of a
Using the geometric mean concept, it is found that the value of a is 18.
----------------------
The geometric mean, of a data-set of n elements, [tex](n_1, n_2, ..., n_n)[/tex], is given by:
[tex]G = \sqrt[n]{n_1 \times n_2 \times ... \times n_n}[/tex]
That is, the nth root of the multiplication of all elements.
----------------------
In this question:
Two elements(n = 2), a and 34.[tex]G = 6\sqrt{17}[/tex]Thus:
[tex]\sqrt{34a} = 6\sqrt{17}[/tex]
We find the square of each side, so:
[tex](\sqrt{34a})^2 = (6\sqrt{17})^2[/tex]
[tex]34a = 36\times17[/tex]
Simplifying both sides by 17:
[tex]2a = 36[/tex]
[tex]a = \frac{36}{2}[/tex]
[tex]a = 18[/tex]
The value of a is 18.

find the value of x and y
<1=(10x)
<2=(10y+20)
<3 =100
Answer:
1008010080x = 10
y = 6
Step-by-step explanation:
We can use the vertical angle theorem to solve for most of this problem. We know that 1/3 will have the same measure and so will 4/2. We can create an equation to solve for 1 and 3.
10x = 100
x = 10
We aren't given angle 4 so we are going to have to solve that ourselves. We can create an equation knowing that 4 and 3 will create a supplementary angle.
100 + z = 180
z = 80
Now, that we have angle 4, we know that angle 2 will have the same measure because they are vertical angles. Now to find the value of y, we can take the angle measure and solve for it.
10y + 20 = 80
10y = 60
y = 6

Answer:
A. All Real Numbers
Step-by-step explanation:
26 + 6b ≥ 2(3b + 4)
~Simplify
26 + 6b ≥ 6b + 8
~Subtract 26 to both sides
6b ≥ 6b - 18
~Subtract 6b to both sides
0 ≥ -18

Calculate the cost for the fuel needed for Sam to drive to Nanaimo to tofino
(15 points)
Answer:
cost of Sam of fuel from Nanaimo to Tofino(207km) is $34.78
Step-by-step explanation:
Diatance from Nanaimo to Tofino is 207km.
Now:
fuel consume in 100km= 12L
fuel consume in 1km=12/100L
We have to find consumption of fuel in 207km.
fuel consume in 207km=12/100 × 207km
= 24.84L
Price of 1 liter= $1.40
Price of 24.84 liters=$1.40 × 24.84
=$34.78

Name 4 collinear points
Answer:
B) H, N, K, I
Step-by-step explanation:
Collinear points are points that are on the same line. Therefore, the answer is B.
The points H, N, K, and I are collinear which is the correct answer that would be an option (B).
What are the collinear points and the coplanar?Collinear points are defined as points that are along a straight line represented by a collinear. Because a straight line may be drawn continuously between any two points, they are always collinear. There can be a collinear relationship from three or more points, although it is not necessary.
A group of points that are coplanar, or a planar surface that extends endlessly in all directions, are all located on the same plane. Four or more points may or may not be coplanar, however, any two or three points are always coplanar.
We have given a line and a planar surface with points H, N, K, I, M, N, O, J, K, and L.
At the line, points H, N, K, and I are collinear.
Hence, the points H, N, K, and I are collinear which is the correct answer that would be an option (B).

g(x) = –2x – 9 What is g(–7)? A. 5 B. –1 C. –5 D. –23
Answer:
D. -23
Step-by-step explanation:
The question wants you to plug in the -7 into the equation. So in this case it wants you to plug the -7 in so it looks like this:
-2(-7)-9
Now it's just simplify which would be easy. Follow PEMDAS(parenthesis, exponents, multiplication, division, addition, subtraction). Do the multiplication first so you get -14-9 and then you'll get -23.
Simplify: 6 × 9 ÷ 3 − 4 × 5 ÷ 2

if angle 1 and angle 2 form a linear pair. if m angle 1=(5x+9) and m angle 2= (3x+11), find the measure of each angle
Answer:
5x+9 = 109
3x+11 =71
Step-by-step explanation:
A linear pair adds to 180
5x+9 + 3x+11 =180
Combine like terms
8x + 20 =180
Subtract 20 from each side
8x +20-20 = 180-20
8x = 160
Divide each side by 8
8x/8 = 160/8
x=20
5x+9 = 5*20+9 = 100+9 = 109
3x+11 = 3*20+11 = 60+11=71
What was Maria’s team score
Answer:
-2
Step-by-step explanation:
So Maria's team skipped 8 turns, losing 8 points, putting them at -8 points. But, Maria's team also guessed correctly 6 times, putting them at -8 + 6 points.
So now we can subtract 8 from 6, or you could subtract 6 from 8(If you do the latter, make sure the answer is negative.):
-8 + 6 = -2
or
6 - 8 = -2
or
8 - 6 = 2 Then make it negative: -2
