Rick is taking a 1-mile ride on his bicycle. For each rotation of his tire, he travels 72 inches. How many rotations will his tire make during the 1-mile trip?
73 rot

Answer:

15

Step-by-step explanation:

if you have 2/5 lengths each time, if you divide that by 6 it gives 15.

Or if you go 2/5 to 4/5 to 6/5 until you have 30/5 because that is how long 6 feet is.

When r varies inversely with x and r = -2 when x = 6, the value of r when x = -3 is 4.

r varies inversely with x, meaning that as one increases, the other decreases. Given r = -2 when x = 6, we can find the constant of variation by using the formula for inverse variation: r₁ * x₁ = r₂ * x₂. Plugging in the values, we have (-2) * 6 = r₂ * -3, which simplifies to r₂ = 4. Therefore, when x = -3, the value of r is 4. This demonstrates the relationship between variables in an inversely proportional scenario, elucidating the concept of variation in algebraic contexts.

Answer: [tex]x=-5[/tex]

Step-by-step explanation:

You need to find the value of the variable "x".

Solve for "x":

Subtract [tex]\frac{5}{6}x[/tex] from both sides of the equation:

[tex]\frac{2}{3}x-\frac{1}{2}-\frac{5}{6}x}=\frac{1}{3}+\frac{5}{6}x\\\\-\frac{1}{6}x-\frac{1}{2} =\frac{1}{3}[/tex]

Add  [tex]\frac{1}{2}[/tex]  to both sides of the equation:

[tex]-\frac{1}{6}x-\frac{1}{2}+\frac{1}{2} =\frac{1}{3}+\frac{1}{2}\\\\-\frac{1}{6}x=\frac{5}{6}[/tex]

Multiply both sides of the equation by -6:

[tex](-\frac{1}{6}x)(-6)=(\frac{5}{6})(-6)\\\\x=-5[/tex]

Answer:

The length of side AB is 5 units

Step-by-step explanation:

* Lets revise how to find the distance between two points

- If there are two points their coordinates are (x1 , y1) and (x2 , y2),

 then we can find the distance between them by this rule:

 d = √[(x2 - x1)² + (y2 - y1)²]

- Now lets solve the problem

∵ A = (4 , -5)

∵ B = (7 , -9)

- To find the length of AB use the rule of the distance above

- Let point A is (x1 , y1) and point B is (x2 , y2)

∵ x1 = 4 and x2 = 7

∵ y1 = -5 and y2 = -9

∴ AB = √[(7 - 4)² + (-9 - -5)²]

∴ AB = √[(3)² + (-4)²]

∴ AB = √[9 + 16] = √25 = 5

* The length of side AB is 5 units

Answer:

1 out of 5

Step-by-step explanation:

There are 5 answer choices total and you're supposed to choose 1 answer so 1 outta 5.

The probability that Peter will choose the correct answer by chance is 1/5 or 0.2 (or 20%).

If Peter has no knowledge about the correct answer to question number 4 on a multiple-choice test with 5 answer choices, the probability of him randomly selecting the correct answer is 1 out of 5.

This probability can be calculated by dividing the number of favorable outcomes (1, since there is only one correct answer) by the total number of possible outcomes (5, since there are 5 answer choices).

Mathematically, it can be represented as 1/5. Thus, the probability that Peter will choose the correct answer by chance is 1/5 or 0.2 (or 20%). This means that, on average, he would be expected to choose the correct answer 20% of the time if he were to guess without any knowledge or information.

Answer:

3m - 15 + m

Step-by-step explanation:

Multiply (m - 5) by 3.

m * 3 = 3m

-5 * 3 = -15

This doesn't apply with +m.

So this leaves it as 3m - 15 + m.

Separate the kite into two triangles.

The base of the triangles would be 6 ( half the width is given as 3, so the full width would be 3 x 2 = 6).

The height of the bottom triangle is given as 10.

The area of a triangle is 1/2 x base x height.

Bottom triangle = 1/2 x 10 x 6 = 30 square units.

For the top triangle you need to find the height using the Pythagorean theorem.

Height = √(5^2 - 3^2) = √(25-9) = √16 = 4

Now the area of the top triangle is 1/2 x 4 x 6 = 12 square units.

Total area = Bottom + top = 30 + 12 = 42 square units.

Step-by-step explanation:

4x+3y=18

3x+4y=3

Multiply the first equation by 3

3(4x+3y)=18*3

12x+9y = 54

Multiply the second equation by -4

-4(3x+4y)=3*-4

-12x -16y = -12

Add these two new equations together to eliminate x

12x+9y = 54

-12x -16y = -12

Answer:

The area of the biggest possible square that fit into the circle is 18 cm²

Step-by-step explanation:

* Lets talk about the square inscribed in a circle

- The square is fit into the circle if its four vertices lie on the

  circumference of the circle

- The diagonal of the square is the diameter of the circle

- The vertices of the square divide the circle into 4 equal arcs

* Look to the attached figure

- The square ABCD fit into the circle M

- A , B , C , D lie on the circumference of the circle M

- The four arcs AB , BC , CD , AD are equal in measure and length

- The diagonal of the square is DB

- The diameter of the circle M is DB

∵ The radius of the circle is 3 cm

∵ The diameter = twice the radius

∴ The diameter of the circle = 2 × 3 = 6 cm

∴ DB = 6 cm

- The rule of the area of the square = (diagonal)²/2

∵ The length of the diagonal is 6 cm

∴ The Area of the square = (6)²/2 = 36/2 = 18 cm²

* The area of the biggest possible square that fit into the circle is 18 cm²

Answer:

The area of the biggest possible square = 36 cm²

Step-by-step explanation:

From the figure attached with this answer shows that, the biggest possible square that would fit into a circle having a radius of 3 cm.

To find the area of square

Side of square  = 2 * radius of circle = 2 * 3 = 6 cm

Area of square = side * side = 6 * 6 = 36 cm²

[tex]r^2=4\sec 2\theta}[/tex]

Step-by-step explanation:

The given equation is:

[tex]x^2-y^2=4[/tex]

We substitute [tex]x=r\cos (\theta)[/tex] and [tex]y=r\sin (\theta)[/tex] to obtain:

[tex]r^2\cos^2\theta-r^2\sin^2\theta=4[/tex]

This implies that:

[tex]r^2(\cos^2\theta-\sin^2\theta)=4[/tex]

Apply double angle identity to obtain:

[tex]r^2\cos 2\theta=4[/tex]

This implies that:

[tex]r^2=\frac{4}{\cos 2\theta}[/tex]

This simplifies to:

[tex]500,000*4,000,000,000,000=2,000,000,000,000,000,000[/tex]

You can rewrite the product in scientific notation form. This form is:

[tex]a*10^n[/tex]

Where "a" is a number between 1 and 10 but lesss than 10, and "n" is an integer.

In scientific notation, the decimal point must be after the first digit.

So, for the product [tex]2,000,000,000,000,000,000[/tex] the decimal point must be moved 18 places to the left.

Then, you get:

[tex]=2*10^{18}[/tex]

Answer:

∠EFA

Step-by-step explanation:

Linear pair : A linear pair is a pair of adjacent angles formed when two lines intersect and the sum of these angles is 180°

Vertical angles: The opposite angles formed by the two intersecting lines are called vertical angles.

Option 1) ∠BFC

Line BE and CF intersect at point F

So, the two adjacent angles formed when two lines intersect are ∠BFC and ∠EFC.

These are linear pair.

So,  ∠BFC is a part of linear pair.

Now by the definition of vertical angles , ∠BFC has no vertical pair.

So, ∠BFC is not a part of vertical pair.

Option 2) ∠CFG

According to the definition of linear pair ∠CFG is not a part of linear pair.

According to the definition of vertical pair ∠CFG is not a part of vertical pair.

Option 3) ∠GFD

According to the definition of linear pair ∠GFD has a linear pair ∠AFG

Thus ∠GFD is a part of linear pair

According to the definition of vertical pair ∠GFD is not a part of vertical pair.

Option 4) ∠EFA

According to the definition of linear pair ∠EFA has a linear pair ∠EFD

Thus ∠EFA is a part of linear pair

According to the definition of vertical pair ∠EFA has a ∠BFD vertical pair.

Thus ∠EFA is a part of vertical pair.

Hence ∠EFA is part of a linear pair and part of a vertical pair.

Answer:

D) EFA

Step-by-step explanation:

Let's see the definition of linear pair and vertical angles.

A linear pair of angles are the adjacent angles, when the angles add upto 180°.

Vertical angles are the  opposite angles when the two lines are intersecting. The vertical angles are equal in measure.

In the given figure there are only two lines, they are AD and BE. Othere are just rays.

By look at the figure, ∠EFA is a linear pair to∠EFD and as well as vertical angle to ∠DFB.

Therefore, the answer is D) EFA

[tex]\left(a+3\right)\left(a-2\right)=a^2+a-6=[/tex]

Step-by-step explanation:

Given expression is [tex]\left(a+3\right)\left(a-2\right)[/tex].

Now we need to multiply this using FOIL.

F = First [tex]=\left(a\right)\left(a\right)= a^2[/tex]

O = Outside [tex]=\left(a\right)\left(-2\right)= -2a[/tex]

I = Inside [tex]=\left(3\right)\left(a\right)= 3a[/tex]

L = Last [tex]=\left(3\right)\left(-2\right)= -6[/tex]

Hence we get :

[tex]\left(a+3\right)\left(a-2\right)=a^2-2a+3a-6=a^2+a-6=[/tex]

Answer:

[tex](a+3)(a-2)=a^2+a-6[/tex]

Step-by-step explanation:

The given expression is:

[tex](a+3)(a-2)[/tex]

Using FOIL, we multiply the;

First terms:[tex]a\times a=a^2[/tex]

Outside terms: [tex]a\times -2=-2a[/tex]

Inner terms:[tex]3\times a=3a[/tex]

Last terms:[tex]3\times -2=-6[/tex]

Putting all together we have:

[tex](a+3)(a-2)=a^2-2a+3a-6[/tex]

This simplifies to [tex](a+3)(a-2)=a^2+a-6[/tex]

AM║ON

To prove:∆AMN ≅ ∆NOA

Lets first draw two diagonals represented by lines MO and AN inside the given quadrilateral AMNO

Now we know if lines are parallel then the alternate interior angles are congruent , hence

∠NMO≅∠AOM

∠MNA≅∠NAO

∠AMO≅∠NOM

∠MAN≅∠ANO

Also by Reflexive Property we have

NA≅NA

MO≅MO

From ASA congruence property of triangles that states that if two angles and a side of two triangles are congruent then the two triangle are said to be congruent, hence we have

ΔAMN≅ΔNOA

ΔMAO≅ΔONM  !

Answer:

∆AMN=∆NOA by rule SSS

The distribution is very simple. Using FOIL.

It states that [tex](a+b)(c+d)=ac+ad+bc+bd[/tex].

Also note that when multiplying expressions we multiply variables and values differently. If we have variables like [tex]x[/tex] their exponents will add. If we have values like 3 we multiply them normally.

For example your practise 3.

[tex](x+3)(2x^2+4)=2x^2\cdot x+4x+3\cdot2x^2+3\cdot4 \\

\underline{2x^3+4x+6x^2+12}

You are basically just working this problem backwards; the way you would find the zeros of the function.

Therefore, to start, make each equal to zero and do the opposite (+ or -) to each side.

-2=x and 2/3=x

0=x+2 and 0=x-2/3

In a function like this, we are usually given an equation like (x+#)(x+#) then we would set these to zero. However, since we are working backwards we are trying to get it in that (x+#)(x+#) form.

(x+2)(x-2/3)

2+2/3 = 2 2/3 or 2.667

2 x 2/3 = 4/3 or 1.334

Your quadratic function is now x^2+2.67x+1.334

or x^2+2 2/3x+4/3.
