If there are 10 people in a room, how many different combinations of three could there be?

Will mark brainiest

Answer:

15

Step-by-step explanation:

1) we can use a proportion

2.25 : 33.75 = 1 : x

in a proportion the product of the terms nearest to equal is equal to the therms furthest than equal

33.75 * 1 = 2.25 * x

x = 33.75/2.25 = 15

Answer:

It will take Amanda 3 track practices to run 29 miles.

Step-by-step explanation:

29-14=15

15/3=5

or

14+5x=29

subtract 14 from both sides

5x=15

divide both sides by 3

x=3

Answer:

6000 m^3

Step-by-step explanation:

The basic formula for the area of a pyramid is 1/3 * b * h

where b is the base and h is the height.

The base is a square, so, we can find the area by squaring the side:

30^2 = 900.

Now, we can plug the values we have into the formula from above:

1/3 * 900 * 20

6000 m^3

Answer:

Perimeter = 2 ( l + w )

if u r given for rectangle thats the formula

Step-by-step explanation:

To find the perimeter of a rectangle, add the lengths of the rectangle's four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width).

Answer:

first option

Step-by-step explanation:

Given

y = 2(x - 3)² + 1

Rearrange making x the subject

Subtract 1 from both sides

y - 1 = 2(x - 3)² ( divide both sides by 2 )

[tex]\sqrt{\frac{y-1}{2} }[/tex] = (x - 3)² ( take the square root of both sides )

± [tex]\sqrt{\frac{y-1}{2} }[/tex] = x - 3 ( add 3 to both sides )

± [tex]\sqrt{\frac{y-1}{2} }[/tex] + 3 = x

Change y into terms of x with x being the inverse, that is

[tex]f^{-1}[/tex] (x) = ±[tex]\sqrt{\frac{x-1}{2} }[/tex] + 3

Answer:

180 units^3

Step-by-step explanation:

Formula for the volume of a right triangular prism: V=1/3Ah (A=Area of base triangle, h=height)

BASE TRIANGLE

A= 1/2bh (base•height)

A= 1/2•10•4

A= 40 units^2

VOLUME OF PRISM

V=1/3Ah

V= 1/3•40•18

V= 180 units cubed

Answer:

B

Step-by-step explanation:

THIS IS HOW YOU CAN FIND ANY MISSING ANGLE - ALSO SOLVES FOR X IN THIS QUESTION.

So, a traingle is 180 degrees.

A line is also 180 degrees.

We know that the angles that make up the triangle are 46, 90, and a missing angle

We need to find the missing angle to find x

To find the missing angle, we must subtract the known angles by the 180 degrees of the traingle.

So:

180-90

=

90

90-46

=

44

So we know the missing angle is 44 degrees.

Let subtract the missing angle(44 degrees) by the 180 degrees of the line:

180-44

=

136

THIS IS WHAT ANSWERS THE OPTION METHOD THAT GIVES THE ANSWER

So x equals 136. This is the missing angle x.

So, remember, both the line and the traingle are 180 degrees.

They both need to find the missing value, which we know is 44

The rest of both the triangle and line is 136 degrees.

Well, 136 degrees on the triangle is the known 90+46 degrees.

Since this will be the same on the line, we can think of x as:

90+46

This looks like answer 1.

Hope this helps! :)

The r-value that represents the strongest correlation is -0.81 (option C). Details about correlation coefficient can be found below.

Correlation coefficient is any of the several measures indicating the strength and direction of a linear relationship between two random variables.

The correlation coefficient is denoted by r. A r-value can either be negative or positive depending on the direction of the relationship.

However, the closer a r-value is to 1, the stronger the relationship. This means that a r-value of -0.81 represents the strongest correlation.

Answer:

B

Step-by-step explanation:

x^2 + 4x + 2 = 0; a=1, b=4, c=2

D= b^2 - 4ac = 16 - 8 = 8>0

-> x1/2= (-b +/- √D)÷2×a= (-4 +/- √8)÷2= 2(-2 +/- √2)÷2

= -2 +/- √2

Answer:

The required height is equal to 5.33 feet.

Step-by-step explanation:

Given that,

Diameter, d = 10 feet

Volume, V = 419 ft.³

We need to find the height the support poles crossed with some of the tepee correctly. Let the height is h.

The tepee is in the form of a  cylinder. The volume of a cylinder is given by :

[tex]V=\pi r^2 h\\\\h=\dfrac{V}{\pi r^2}\\\\h=\dfrac{419}{3.14\times 5^2}\\\\h=5.33\ ft[/tex]

So, the required height is equal to 5.33 feet.

Answer:

Step-by-step explanation:

6). Equation of the line has been given as,

    4x + 9y = -9

    By converting this equation into y-intercept form,

    9y = -4x - 9

    [tex]y=-\frac{4}{9}x-\frac{9}{9}[/tex]

    [tex]y=-\frac{4}{9}x-1[/tex]

    By comparing this equation with y = mx + b

    Here, m = Slope of the line

    b = y-intercept

    Slope of the equation (m) = [tex]-\frac{4}{9}[/tex]

    y-intercept (b) = -1

8). Equation of the line is,

    5x + 3y = 12

    3y = -5x + 12

    [tex]y=-\frac{5}{3}x+\frac{12}{3}[/tex]

    [tex]y=-\frac{5}{3}x+4[/tex]

    Slope of the line = [tex]-\frac{5}{3}[/tex]

    y-intercept = 4
