The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. The equation 9 x 5 = 45 consists of the two equations are separated by the 'equal' sign.

Assume that a team has N players.

Each squad may have anywhere from 3 to 5 players, so

3 ≤ 5 ...(i)

Let P represent a player's total points in a single game round.

Each round of the game allows for a maximum of 10 points for each player, so

0 ≤ p ≤ 10 ....( i)

(1) Elena assembled a team of five people.

As a result, 5 players' points in 1 round equal 5P.

Equation (ii) yields the range of

0 ≤ 5p ≤ 50.

As a result, Elena's team's points total ranges from 0 to 50.

(2) If each shot is off by one point, then

One player's points in one round are equal to 10-1=9.

So, 9 x 5 = 45 points were collected by 5 players in 1 round.

(3) Assume that R represents the number of teams as an integer.

the game involves at least three teams, therefore

R ≥ 3 ...( iii)

Given that N players make up one team,

R team has NR players, where R is 3, 4, or more.

Next, using equation (i)

3R ≤ 5R

Therefore, the number of players ranges from 3R to 5R if there are at least 3 teams.

The game can have anywhere from 3x3=9 to 5x3=15 players when R=3.

Answer:

(I) Between 0 and 50.

(ii) Between 3 and 5.

(iii) Between 3R and 5R, where R = 3,4,5,...

Answer:

24° , 60° , 96°

Step-by-step explanation:

sum the parts of the ratio, 2 + 8 + 5 = 15 parts

divide the sum of the angles in a triangle by 15 to find the value of one part of the ratio.

180° ÷ 15 = 12° , then

2 parts = 2 × 12° = 24°

5 parts = 5 × 12° = 60°

8 parts = 8 × 12° = 96°

the 3 angles in the triangle are 24° , 60° , 96°

First convert the angle measure from radians to degrees using the formula

Were θ represents the angle of interest

So for this exercise the angle is pi, so:

Now using the calculator you can determine tha tangent of negative 180º

tan(-180º)=0

So the tangent of negative pi should also be zero

The standard form of a hyperbola with center (h,k) is

We know the vertices are at (5,0) and (-5,0)

The vertices are at (h+a,k) and ( h-a,k)

The center must be at (0,0) and the a value is 5

The coordinates of the foci are at ( h+c,k) and ( h-c, k) and we know one of the foci is at (6,0)

c is equal to 6

We know that c^2 = a^2+b^2

6^2 = 5^2 + b^2

The radius of the snowball decreasing by -2.

What is rate?

A rate is the ratio of two related values expressed in various units. [1] If one of these numbers is used as the ratio's denominator and it is assumed that this quantity can be altered in a predictable way (i.e., is an independent variable), then the numerator of the ratio represents the rate of change in the other (dependent) variable.

Let r(t) be a function of the radius of the sphere over time.

The volume of the sphere over time is then [tex]v(t) = \frac{4}{3} \pi r(t)^3[/tex]

The rate of change of the volume is then  [tex]v'(t) = 4\pi r(t)^2r'(t)[/tex]

Comparing is to the surface area of the sphere [tex]s(t) = 4\pi r(t)^2[/tex],  it seems perfectly possible for the volume to decrease at a rate equal to  2s(t).

That just means that

[tex]v'(t) = -2s(t)\\4\pi r(t)^2r'(t) = -8\pi r(t)^2\\r'(t) = -2[/tex]

Therefore, the radius must shrink by two units of distance every unit of time, it is now obvious.

The given statement "Sal earns $480 per week. Lidia earns $300 per week. Are their salaries proportional if Sal works 40 hours per week and Lidia works 25 hours per week" is true.

As given in the question,

If one amount is proportional to another, the two amounts increase and decrease at the same rate so there is always the same relationship between them

a:b = c:d

a ÷b = c ÷d

ad = bc

let Sal earns $480 per week and he works 40hours per week

  480÷40 = 12

Lidia earn $300 per week and she works 25 hours per week

   300÷25 = 12

Cross product of their salaries is  

480×25=1200

300×40=1200

The ratio of their salaries and their product are equal.

Hence, The given statement "Sal earns $480 per week. Lidia earns $300 per week. Are their salaries proportional if Sal works 40 hours per week and Lidia works 25 hours per week" is true

Hello!

First, let's write the possible options:

Dice: 6 different results.

• 1, 2, , 4, 5, 6.

Spinner: 4 different results.

• A, B, C, D.

Knowing it, let's solve each alternative of your exercise:

In the dic, we have 6 possible results and we want a specific number. SOo, we can write it as 1/6.

In the spinner, we have 4 possible results and we want a specific one too. So, we have 1/4.

Now, remember he r"and" rule: when we consider two events happening simultaneously, we must multiply their probabilities.

Solving:

We'll solve it in a similar way.

We have three possible odd numbers (1, 3, 5) in a total of 6 options. So, 3/6 = 1/2.

For the spinner, the reasoning will be the same: 1/.

Let's calculate:

In a dice, we have four numbers less than 5: 1, 2, 3,4.

In the spinner, there are 3 consonants (B, C, D).

EXPLANATION

The triangle in the picture is dilated with scale factor 2.

This simply means that the size of the triangle was increased by 2.

To do this, first, let us write out the cordinates of the vertices of the original triangle:

M(-2, 1)

P(2, -2)

A(3, 5)

To dilate this, we will multiply the cordinates by 2, they become:

M' (-4, 2)

P' (4, -4)

A' (6, 10)

Therefore, the vertex M on the image after the dilation is (-4, 2).

4x² - 18x - 5 cannot be factored by grouping.

Factoring a polynomial involves writing it as a product of two or more polynomials.

In other words, it is a process of finding the factor.

Therefore, let's factor the quadratic equation as follows:

4x² - 18x - 5

Factorization by grouping means that we need to group the terms with common factors before factoring.

The grouping method can be used to factor polynomials whenever a common factor exists between the groupings.

Hence,

4x² - 18x - 5 cannot be factorise by grouping because it has no common factor.

in other word, we cannot, however, use the grouping method to factor 4x² - 18x - 5 because factoring out the GCF from both groupings does not yield a common factor.

Recall:

The height of the tree is approximately 2.11 meters if Kayla is 1.85 meters tall. At 12 noon, she measures the length of a tree's shadow to be 28.15 meters.

It is defined as the law to prove that two triangles have the same shape, but it is not compulsory to have the same size. The ratio of the corresponding sides is in the same proportions and the corresponding angles are congruent.

It is given that:

Kayla is 1.85 meters tall. At 12 noon, she measures the length of a tree's shadow to be 28.15 meters.

D = 39.75 m

d = 34.9 m

H:h = D:d

H/1.85 = 39.75/34.9

H = 2.11 m

Thus, the height of the tree is approximately 2.11 meters if Kayla is 1.85 meters tall. At 12 noon, she measures the length of a tree's shadow to be 28.15 meters.

Depending on the particular isotope, this process can take a variety of times. While for some it will take years and decades, it will just take a microsecond for individuals. Usually, the isotope will decay into a different element or isotope.

Isotopes are two or more different atom types that share the same atomic number and place in the periodic table but have different quantities of neutrons in their nuclei, resulting in various nucleon numbers.

If we start with 180 g of the isotope, after one half-life the quantity will diminish to  180 g/2 = 90 g which exists half the original quantity.

This can be written mathematically as: [tex]$180 g\left(\frac{1}{2}\right)^1$[/tex]

After the second half life: [tex]$\frac{90 g}{2}=45 g=\frac{180 g}{4}=(180 g)\left(\frac{1}{2}\right)^2$[/tex]

After the third half life: [tex]$\frac{45 g}{2}= 22.5 g=\frac{180 g}{8}=(180 g)\left(\frac{1}{2}\right)^3$[/tex]

But now that we are dividing the amount by 2 to a power that grows as the number of half-lives, we can start to notice a pattern.

The original quantity can then be rapidly computed for six half-lives using the formula below:

[tex]$(180 g)\left(\frac{1}{2}\right)^6=(180 g)\left(\frac{1}{64}\right)=\frac{180 g}{64}=2.8 g$$[/tex]
