Answer:
Se refieren a las unidades de tiempo del sistema sexagesimal
9:25 son 9 minutos y 25 segundos
33:41:38 son 33 horas, 41 minutos y 38 segundos.
Step-by-step explanation:
El sistema sexagesimal se utiliza para medir tiempos y ángulos.
El tiempo se mide en horas,minutos y segundos
En cambio, los ángulos se miden en grados,minutos y segundos.
Los dos puntos '':'' sirven para separar las unidades.
La base de este sistema es el número 60 :
60 segundos ⇒ 1 minuto
60 minutos ⇒ 1 hora
Eso en cuanto a tiempo
En cuanto a grados :
60 segundos ⇒ 1 minuto
60 minutos ⇒ 1 grado
Cuando tengo dos números como en 9:25 , el número de la derecha corresponde a los segundos y el de la izquierda a los minutos
Entonces, 9:25 son 9 minutos y 25 segundos
Por otro lado, cuando tengo 3 números, como en 33:41:38, el número de la derecha corresponde a los segundos, el de en medio al de los minutos y el de la izquierda al de las horas (si nos referimos a unidades de tiempo).
Entonces, 33:41:38 son 33 horas, 41 minutos y 38 segundos.

~Apple exponent rule [ a^b * a^c = a^b+c ]
3^2-8+0
~Simplify
3^-6
~Use exponent rule [ a^-b = 1/a^b ]
1/3^6
~Simplify
1/729
Best of Luck!
Answer:
3^-6 which equals 1/3^6
Step-by-step explanation:
all you do is add the exponents.
3^0 is equal to 0 so that one doesn't matter, you just cross it out.
now you're left with 3^2x3^-8
so add 2+(-8) which is -6 so the answer is: 3^-6
since the exponent is negative, you put a 1 above the problem, making it a fraction: 1/3^-6

The shaded region represents the possible solutions of the inequality.
What is a function? What is equation modelling? What is a mathematical equation and expression?In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.
Given is the inequality -
y ≤ (1/2)x - 4
Refer to the graph of the inequality attached. It is showing the inequality being plotted. The shaded region represents the possible solutions of the inequality.
Therefore, the shaded region represents the possible solutions of the inequality.

3km: 500m in lowest terms.
Answer:
6:1Step-by-step explanation:
To write 3km: 500m in its lowest terms. we need to make sure the units are the same.
Converting 3km to metres:
Since 1km = 1000m
3km = (3*1000)m
3km = 3000m
The expression becomes 3000m:500m
3000m:500m = 3000/500
3000m:500m = 6*500/500*1
3000m:500m = 6/1
Hence 3km: 500m in its lowest term is 6:1
(01.05 MC)Which fraction is equivalent to 2 over negative 6?
Answer:
1/(-3)
Step-by-step explanation:
Simplify the following:
2/(-6)
Hint: | Reduce 2/(-6) to lowest terms. Start by finding the GCD of 2 and -6.
The gcd of 2 and -6 is 2, so 2/(-6) = (2×1)/(2 (-3)) = 2/2×1/(-3) = 1/(-3):

A ball is thrown into the air with a velocity of 34 ft/s. It's height in feet after t seconds is given by y=34t-26(t)^2. Find the avg velocity for the time period beginning when t(0)= 3 seconds and lasting for the given time t= .01 seconds: ???
Answer:
The average velocity of the ball at the given time interval is -122.3 ft/s
Step-by-step explanation:
Given;
velocity of the ball, v = 34 ft/s
height of the ball, y = 34t - 26t²
initial time, t₀ = 3 seconds
final time, t = 3 + 0.01 = 3.01 seconds
At t = 3 s
y(3) = 34(3) - 26(3)² = -132
The average velocity of the ball in ft/s is given as;
[tex]V_{avg} = \frac{y(3.01)-y(3)}{3.01 -3}\\\\V_{avg} = \frac{34(3.01)-26(3.01)^2-y(3)}{3.01 -3}\\\\V_{avg} = \frac{-133.223-y(3)}{0.01}\\\\V_{avg} = \frac{-133.223-(-132)}{0.01}\\\\V_{avg} =\frac{-1.223}{0.01}\\\\V_{avg} = -122.3 \ ft/s[/tex]
Therefore, the average velocity of the ball at the given time interval is -122.3 ft/s
What is the slope-intercept form equation of the line that passes through (5.7) and (8, 22)?
A) y=-5x+18
B) y=5x+18
C) y=5x-18
D) y=-5x-18
Answer:
C . y= 5x -18
Step-by-step explanation:
[tex](5,7) = (x_1 ,y_1) \\ (8,22)=(x_2,y_2)[/tex]
Plug in the values into the following equation
[tex] \frac{y - y _1}{x - x_1} = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
[tex] \frac{y - 7}{x - 5} = \frac{22 - 7}{8 - 5} \\ \frac{y - 7}{x - 5} = \frac{15}{3} [/tex]
Cross Multiply
[tex]3(y - 7) = 15(x - 15) \\ 3y - 21 = 15x - 75[/tex]
Collect like terms and simplify
[tex]3y = 15x - 75 + 21 \\ 3y = 15x - 54[/tex]
Divide through by 3
[tex] \frac{3y}{3} = \frac{15x}{ 3 } - \frac{54}{3} \\ y = 5x - 18[/tex]

What is the correct classification for JML?
Answer:
Option (2)
Step-by-step explanation:
From the picture attached,
m∠JKL = m∠JMK + m∠KML
Since, m∠KML + m∠HML = 180° [Linear pair of the angles]
m∠HML = 180° - m∠KML
= 180° - 132°
= 48°
Therefore, m∠JML = 41° + 48°
= 89°
Since measure of angle JML is less than 90°, by definition of an acute angle it will be an acute angle.
Option (2) will be the answer.
Answer:
The answer is acute bru
