x = 80

Answer:

The Rockets' team has the better record.

Step-by-step explanation:

The Blazers hockey team has played 12 games but they won only 7 out of the 12 games, so that means that they loss the other 5 games. So that makes the Blazers record 7 wins and 5 losses.

The Rockets' team has played 8 games but they won only 5 out of the 8 games, so that means that they loss the other 3 games. So that makes the Rockets' record 5 wins and 3 losses.

So, the Rockets' team has the better record because they loss less games than the Blazers team did.

Answer:

40°F

Step-by-step explanation:

When Tyrese fell asleep one night, the temperature was 24°F.

When Tyrese awoke the next morning, the

temperature was -16°F.

Letting + denote a rise in

temperature and - denote a drop in temperature, what was the change in temperature from the time Tyrese fell asleep until the time he awoke?

The temperature dropped from a high temperature to a low one : from 24° to -16°

This can be expressed mathematically as 24 - (-16), with - denoting a drop in the temperature

=24-(-16)

=24+16

=40°F

Please mark me brainliest

Answer:

a change of -40°F, i.e., a drop.

Step-by-step explanation:

use the formula

   change = end - start

and find -16 - 24 = -40

x = 45

Step-by-step explanation:

180-136 = 44

x - 1 = 44

x = 44 + 1

x = 45

x = 45°

Step-by-step explanation:

The two angles are supplementary so

[tex]136° + (x-1) = 180°[/tex]

[tex]\Rightarrow x - 1 = 44°[/tex]

or

[tex]x = 45°[/tex]

Answer:

The answer is 8b

Step-by-step explanation:

Hey, a variable is a filler for an unknown number. Don't let it confuse you too much!

If there were 5 teams, there would be 8(5) = 40 players, right??

With b teams, there are 8b players. We are lazy as mathematicians and don't say 8(b) or 8 x b. It's just 8b.

Thus, The answer is 8b

The polynomial expressed as trinomial is 3x² - 21x + 30

Polynomial is an expression that involves only the operations of addition, subtraction, multiplication of variables.

Polynomials can be classified based on the number of terms as binomial, trinomial.

Trinomial is a polynomial with 3 terms.

Given the polynomial:

(x - 5)(3x - 6)

= 3x² - 15x - 6x + 30

= 3x² - 21x + 30

Answer:

12/13

Step-by-step explanation:

I got a 100% on the test

The trigonometric function sin is the ratio of perpendicular to hypotenuse thus sinθ = 5/13.

The fundamental 6 functions of trigonometry have a range of numbers as their result and a domain input value that is the angle of a right triangle.

The trigonometric function is only valid for the right angle triangle and it is 6 functions which are given as sin cos tan cosec sec cot.

As per the given right angle triangle,

By sine function.

sinθ = perpendicular/hypotenuse

sinθ = 5/13

Hence "The trigonometric function sin is the ratio of perpendicular to hypotenuse thus sinθ = 5/13".

Answer:

  -3 ≤ x ≤ 19/3

Step-by-step explanation:

This inequality can be resolved to a compound inequality:

  -7 ≤ (3x -5)/2 ≤ 7

Multiply all parts by 2.

  -14 ≤ 3x -5 ≤ 14

Add 5 to all parts.

  -9 ≤ 3x ≤ 19

Divide all parts by 3.

  -3 ≤ x ≤ 19/3

_____

Additional comment

If you subtract 7 from both sides of the given inequality, it becomes ...

  |(3x -5)/2| -7 ≤ 0

Then you're looking for the values of x that bound the region where the graph is below the x-axis. Those are shown in the attachment. For graphing purposes, I find this comparison to zero works well.

__

For an algebraic solution, I like the compound inequality method shown above. That only works well when the inequality is of the form ...

  |f(x)| < (some number) . . . . or ≤

If the inequality symbol points away from the absolute value expression, or if the (some number) expression involves the variable, then it is probably better to write the inequality in two parts with appropriate domain specifications:

  |f(x)| > g(x)   ⇒   f(x) > g(x) for f(x) > 0; or -f(x) > g(x) for f(x) < 0

Any solutions to these inequalities must respect their domains.

Las medidas o parámetros que se sitúan hacia el centro de un conjunto de valores, con el objetivo de analizar un análisis profundo de los resultados, son denominadas "medidas de tendencia central".

Una medida de tendencia central da una impresión del centro de una cantidad de datos o una distribución. Dependiendo de la medida de centro utilizada, el centro puede significar el centro de los datos o la distribución, o el lugar más probable donde se encuentran la mayoría de los datos.

Por tanto, una medida de centro da una impresión de los datos o la distribución en un número y, a veces, también se utiliza como un resumen de un solo número de los datos o la distribución. Las medidas conocidas del centro son la media aritmética y geométrica, la mediana, la moda y el centro del rango (el valor exactamente entre los valores mínimo y máximo).
