Answer: The answer is 15 * 14

Step-by-step explanation:

You start with 15 people to choose from to select a president, so you have 15. After removing one person 15-1,=14 you have fourteen people to choose from, to select a vice president. This gives you 15*14.

The expression that can be used to represent the number of ways that a president and a vice-president can be chosen out of a group of 15 people is 15×14 or ¹⁵P₂.

Permutation helps us to know the number of ways an object can be arranged in a particular manner. A permutation is denoted by 'P'.

[tex]^nP_r = \dfrac{n!}{(n-r)!}[/tex]

where,

n is the number of choices available,

r is the choices to be made.

The number of people that are available for the post of the president is 15, while the number of people that are available for the post of vice-president after the president is selected is 14. Therefore,

Number of ways in which president and vice-president can be selected

= ¹⁵P₂

= 15 × 14

Hence, the expression that can be used to represent the number of ways that a president and a vice-president can be chosen out of a group of 15 people is 15×14 or ¹⁵P₂.

Answer:

18 Inches total of rope

Step-by-step explanation:

9+9=18

or

9 x 2 = 18

You can do this two ways:

1. You can multiply 9 (how long the rope is) by 2 (how many ropes you have. so...

length of rope * number of ropes

9 * 2 = 18

2. Or you  can add 9 plus nine together and it will give you the same answer. so...

9 + 9 = 18

To find the measure of ∠ONK in rectangle MPKN with given conditions, it's determined through the congruency of triangles and properties of a rectangle that ∠ONK is 72°.

The question involves finding the measure of ∠ONK in rectangle MPKN, where the diagonals intersect at point O, and a line segment OA is an altitude of triangle MOP with m∠AOP = 18°. Given the properties of a rectangle, we know that its diagonals bisect each other and are equal in length. Therefore, triangles MOP and NOP are congruent.

Because OA is the altitude to hypotenuse MP of triangle MOP, it creates two right triangles, OAM and OAP. The angle ∠AOP is given as 18°, which means ∠MOA = 90° - 18° = 72° since triangle OAM is a right-angled triangle. Because the diagonals of the rectangle bisect each other at O, triangle ONP is congruent to triangle OMP, and hence ∠ONK (which is also ∠ONP) is equal to 72° as angle ∠ONP is supplementary to ∠MOA in rectangle MPKN.

Answer:

48 cm²

Step-by-step explanation:

Let's call the width and height of the rectangle w and h.

w / h = 3 / 4

2w + 2h = 28

Solve the system of equations with substitution.

w = 3/4 h

2 (3/4 h) + 2h = 28

3/2 h + 2h = 28

7/2 h = 28

h = 8 cm

So the width is:

w = 3/4 (8)

w = 6 cm

So the area is:

A = wh

A = 48 cm²

Answer:

Figure A sides are 1/4 the size of Figure B

The top of Figure A = 4, the top of Figure B = 1.

EXPLANATION

The given exponentiial expression is

[tex] {x}^{ - 8} \bullet {x}^{ - 2} [/tex]

We simplify using the rule:

[tex] {a}^{m} \times {a}^{n} = {a}^{m + n} [/tex]

We apply this property to get:

[tex]{x}^{ - 8} \bullet {x}^{ - 2} = {x}^{ - 8 + - 2}[/tex]

We simplify to get;

[tex]{x}^{ - 8} \bullet {x}^{ - 2} = {x}^{ - 10}[/tex]

We rewrite as a positive index to get;

[tex]{x}^{ - 8} \bullet {x}^{ - 2} = \frac{1}{ {x}^{10} } [/tex]

Answer:

when you move a decimal point to the left you are increasing the number

when you move a decimal to the right you are decreasing the number

Answer:

44, 46

Step-by-step explanation:

The integers are both even, so if the smaller one is x, then the larger one is x+2.

Therefore:

((x) + (x+2))² = 4048 + (x)² + (x+2)²

(2x + 2)² = 4048 + x² + x² + 4x + 4

4x² + 8x + 4 = 2x² + 4x + 4052

2x² + 4x - 4048 = 0

x² + 2x - 2024 = 0

(x + 46) (x - 44) = 0

x = -4+, 44

Since x must be positive, x = 44.  And x+2 = 46.  So the numbers are 44 and 46.

Let's check:

(44 + 46)² = 8100

4048 + 44² + 46² = 8100

We need to drag the tiles and place them in boxes to form the correct pairs.

The given options are:-

1) [tex]9x^{2}+3x-20[/tex]

2) [tex](4x-3y)^{2}[/tex]

3) [tex](3x+5)(3x-4)[/tex]

4)[tex](3x+2)(9x^{2} -6x+4)[/tex]

First we simplify the all given factor and then compare with provided options

2) [tex](4x-3y)^{2}[/tex]

=[tex]16x^{2}+9y^{2}-24xy[/tex]

3) [tex](3x+5)(3x-4)[/tex]

[tex]9x^{2}-12x+15x-20[/tex]

[tex]9x^{2}+3x-20[/tex]

Here we can see equation (3) match with (1)

so, [tex]9x^{2}+3x-20=(3x+5)(3x-4)[/tex]

Hence, the correct match is shown in figure-1

The expressions that are equivalent should be matched as follows;

9x² + 3x - 20 ↔ (3x + 5)(3x - 4)

In order to match the equivalent expressions, we would have to either expand or factor each of the given expressions as follows;

9x² + 3x - 20

By applying the sum-product pattern, we have:

9x² + 15x - 12x - 20

By writing the common factor from the two pairs, we have:

(9x² + 15x) + (-12x - 20)

3x(3x + 5) - 4(3x + 5)

(3x + 5)(3x - 4)

Next, we would expand the expression (4x - 3y)²;

(4x - 3y)(4x - 3y)

16x² - 12xy - 12xy + 9y²

16x² - 24xy + 9y²

Answer:

[tex]A = 301.59\ cm^2[/tex] or [tex]A=96\pi\ cm^2[/tex]

Step-by-step explanation:

The lateral area of a cylinder is calculated by the following formula

[tex]A = 2\pi r * h.[/tex]

Where r is the radius of the right cylinder and h is the height

In this case we know that the diameter d of the cylinder is

[tex]d=2r\\\\r=\frac{d}{2}\\\\r=\frac{12}{2}\\\\r=6\ cm[/tex]

[tex]h=8\ cm[/tex]

Therefore the lateral area is:

[tex]A = 2\pi*6 * 8.[/tex]

[tex]A = 96\pi[/tex]

[tex]A = 301.59\ cm^2[/tex]

Answer:

The lateral area of a right cylinder = 96π cm²

Step-by-step explanation:

Points to remember

The lateral area of a right cylinder  = 2πrh

Where r - Radius of cone and

h - Height of cone

To find the lateral surface area

Here diameter d = 12 cm

then radius r = d/2 = 12/2 = 6 cm

And h = 8 cm

Lateral surface area =  2πrh

= 2 * π *6 * 8 = 96π cm²

Therefore the lateral area of a right cylinder = 96π cm²

Answer:

The value of y when x = 5 and z = 16 is 272

Step-by-step explanation:

* Lets Talk about the direct variation

- y is varies jointly (directly) as x and z, that means there are direct

  relation between y , x and z

- y increases if x increases or z increases

∴ y ∝ x × z

- To change this relation to equation we use a constant k

∴ y = k (x) (z), where k is the constant of variation

- To find the value of k we substitute the values of x , y and z in

  the equation above

∵ y = 136 when x = 5 and z = 8

∴ 136 = k × 5 × 8

∴ 136 = 40 k ⇒ divide both sides by 40

∴ k = 3.4

- Substitute this value in the equation

∴ y = 3.4 (x) (z)

∵ x = 5 , z = 16

∴ y = 3.4 (5) (16) = 272

∴ The value of y when x = 5 and z = 16 is 272

Answer:

The correct answer is B.

Step-by-step explanation:

If y varies jointly as x and z, then we can write the join variation equation.

[tex]y=kxz[/tex], where 'k' is the constant of proportionality.

If y = 136 when x = 5 and z = 8,then

[tex]136=k(5)(8)[/tex],

[tex]\implies 136=40k[/tex]

[tex]\implies \frac{136}{40}=k[/tex]

[tex]\implies \frac{17}{5}=k[/tex].

The variation equation now becomes:

[tex]y=\frac{17}{5}xz[/tex]

when x = 5 and z = 16, then

[tex]y=\frac{17}{5}(5)(16)[/tex]

[tex]y=17(16)[/tex]

[tex]y=272[/tex]

The correct answer is B.

Answer:Two <‘s supplementary to equal <‘are=

I got this correct on Odyssey:)

Answer:

Option B.

Step-by-step explanation:

∠1 and ∠3 are supplementary and ∠2 and ∠4 are supplementary.

Because they are exterior sides in opposite rays.

In other words ∠1 + ∠3 = 180° and ∠2 + ∠4 = 180°

and it is given that ∠1 ≅ ∠2

So ∠3 ≅ ∠4

Since Two angles supplementary to equal angles are equal will be the reason.

Option B is the correct option.

If the diameter of a circle is 50 yards the radius must be 25 yards.

This is because the radius is always half the diameter of the circle. Since we know the diameter is 50 yards, half of 50 is 25 so the radius must be 25 yards.

Have a great day!

The radius of the circle is 25 yards.

A circle is a round shaped figure which has all its points in one plane and the distance between all the points on its circumference to the center of the circle is equal .

It is given that

Diameter of a circle is 50 yards.

Radius of a circle =  Diameter of circle / 2

Radius of the circle = 50/2 = 25 yards
