Answer:

X can be - 2 or 6.

Step-by-step explanation:

d=5

d=sqrt((x2-x1)^2 +(y2-y1)^2)

5=sqrt((x-2)^2 +(5-2)^2)

5^2 =(x-2)^2 +3^2

25=(x-2)^2 +9

(x-2)^2 =25-9

(x-2)^2 =16

x-2=sqrt(16)

x-2=4

x=4+2

x=6;

x-2=-4

x=-4+2

x=-2

A stadium has 47000 seats seats sell for $35 in section a $30 in section B and 25 in section c the number of seats in section A

Rainbow [258]

Answer: a section holds 11,750 seats

$1,483,500 from one sold out event

47,000 seats in total, 3 sections (A = B + C)

A = B*2, C*2

47,000 / 4 = 11,750

Cindy claims that 4x/12x= 1/3. Enter a whole number that supports Cindy's claim, and then enter a whole number that does not sup

galina1969 [7]

A whole number that would support Cindys claim would be 2 because if u do the ,math it would be 8/24 which would be .333 repeating which is simplify to 1/3 and i do not know a number that would not work.

David made a class banner out of a large rectangular piece of paper. He cut a

Irina18 [472]

Answer:

100 in²

Step-by-step explanation:

The area of the banner is equal to the area of the initial rectangle minus the area of the cutout triangle.

The rectangle has a height of 8 inches and width of 14 inches, so its area is:

A = (8 in) (14 in) = 112 in²

The triangle has a base of 8 inches and a height of 3 inches, so its area is:

A = ½ (8 in) (3 in) = 12 in²

So the area of the banner is 112 in² − 12 in² = 100 in².

If the geometric mean of a and 34 is 6 sqrt(17) find the value of a

Alborosie

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, $(n_1, n_2, ..., n_n)$ , is given by:

$G = \sqrt[n]{n_1 \times n_2 \times ... \times n_n}$

That is, the nth root of the multiplication of all elements.

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

In this question:

Two elements(n = 2), a and 34.
$G = 6\sqrt{17}$

Thus:

$\sqrt{34a} = 6\sqrt{17}$

We find the square of each side, so:

$(\sqrt{34a})^2 = (6\sqrt{17})^2$

$34a = 36\times17$

Simplifying both sides by 17:

$2a = 36$

$a = \frac{36}{2}$

$a = 18$

The value of a is 18.
