Si Doña Clara lleva un tratamiento con 2 medicamentos una toma cada 8 horas y la otra toma cada 12 horas, ¿Despues de la primera toma, a las cuantas horas volverá a tomar los dos medicamentos?
Respuesta:
24 horas
Explicación paso a paso:
El primer medicamento se toma cada 8 horas.
El segundo medicamento se toma cada 12 horas.
Para Obtian el momento en que ambos medicamentos se volverán a tomar juntos:
Encontramos el mínimo común múltiplo de 8 y 12
Múltiplos de:
8 = 8, 16, 24, 32, 40, 48, 56
12 = 12, 24, 36, 48, 60
El mínimo común múltiplo de 8 y 12 es 24.
Por lo tanto, ambos medicamentos se volverán a tomar después de 24 horas.

What is the common ratio of the following sequence?
-1, 6, - 36, 216 . . .
r = -6
r = 1296
r = -1
r = 7
Answer:
r = -6
Step-by-step explanation:
-1 × -6 = 6
6 × -6 = -36
-36 × -6 = 216
Answer:
-6
Step-by-step explanation:
To find the common ratio, take the second term and divide by the first term
6/ -1 = -6
Check the third term and divide by the second term
-36/-6 = -6
And the 4th divided by the third
216/ -36 = -6
The common ratio is -6

Is the percent increase from 50 to 70 equal to thhe percent decease from 70 to 50
Answer:
No
Step-by-step explanation:
The amounts of change are the same, but the original amounts are different. The ratio for the percent increase from 50 to 70 is 20/50, or 40%. The ratio for the percent decrease from 70 to 50 is 20/70, or about 29%.
Answer:
Step-by-step explanation:
Though the difference is the same, the original value is different. Therefore they are not the same.
Percentage increase from 50 to 70
[tex]=\frac{70 - 50}{50} \times 100\\\\=\frac{20}{50} \times 100 = 40 \%[/tex]
Percentage decrease from 70 to 50
[tex]= \frac{70-50}{70} \times 100\\\\= \frac{20}{70} \times 100 = 28.57 \%[/tex]
A line that includes the points (-9, 6) and (-3, s) has a slope of -1. What is the value of s?
Answer:
s=0
Step-by-step explanation:
We have two points so we can use the slope formula
m = (y2-y1) / x2-x1)
-1 = (s-6)/(-3 - -9)
-1 = (s-6)/(-3 +9)
-1 = (s-6)/(6)
Multiply each side by 6
6*-1 = s-6
-6 = s-6
Add 6 to each side
-6+6 = s-6+6
s=0
Answer:
[tex] \large\sf \: s = 0[/tex]
Value of s is 0.
Step-by-step explanation:
Here,
A line that includes 2 two points are ( -9 ,6) and (-3, s) and has a slope of - 1.
Using slope formula
m = ( y ² - y ¹ ) / ( x ² - x ¹)
Where,
m , is the slope which is -1( y ² - y ¹ ) = ( s - 6 )( x ² - x ¹) = ( - 3 - ( - 9 ) )substitute the values into the formula
-1 = ( s - 6 ) / ( - 3 - ( - 9 ) )
-1 = ( s - 6 ) / ( - 3 + 9 )
- 1 = ( s - 6 ) / ( 6 )
multiply each side by 2
- 1 × 6 = s - 6 × 6 / 6
- 6 = s - 6
- 6 + 6 = s - 6 + 6 ..( add 6 to each side)
0 = s

so i know g(x)=3k-2x² and g(-3)=-6
how do i know what g(x) ad k are?
Answer:
find k by putting -3 where there is x than -6 on g(x)
Step-by-step explanation:
g(x)=3k-2x²
-6=3k-2(-3)²
-6=3k-18
-6+18=3k
12=3k
12÷3=3k÷3
4=k
A plane, initially traveling 150 mi./hr. 100 east of north, suddenly enters a region where the wind is blowing at 50 mi./hr. from the southwest.
What is the plane’s resultant direction?
Answer:
the Velocity of the plane is 100 mi/hr along the northeast direction
Step-by-step explanation:
According to the Question,
Given That, the Initial velocity of the plane is 150 mi/hr along the east north direction and the wind is blowing at 50 mi/hr along the southwest directionsince the velocity of wind and plane is exactly opposite
the relative velocity of the plane with respect to the wind is given by[tex]V_{r} = V_{p} -V_{w}[/tex] , where [tex]V_{p}[/tex] is the velocity of plane = 150mi/hr and [tex]V_{w}[/tex] = velocity of wind = 50 mi/hr
Therefore, Relative Velocity = 150-50 ⇒ 100mi/hr along northeast directionThus, the velocity of the plane is 100 mi/hr along the northeast direction
The values in a dataset are 3.5, 2.5, 2.5, 3.5, and 3.0. If Xbar (sample mean) = sigma X / n, what is the mean for the sample?
Answer:
[tex]\bar x = 3.0[/tex]
Step-by-step explanation:
Given
[tex]x: 3.5, 2.5, 2.5, 3.5, 3.0[/tex]
Required
The sample mean
This is calculated using:
[tex]\bar x = \frac{\sum x}{n}[/tex]
So, we have:
[tex]\bar x = \frac{3.5+ 2.5+ 2.5+ 3.5+ 3.0}{5}[/tex]
[tex]\bar x = \frac{15.0}{5}[/tex]
[tex]\bar x = 3.0[/tex]

*Chuckles* my GPA is in danger
Answer:
A
Step-by-step explanation:
Exponential growth is when numbers increase rapidly in an exponential fashion so for every x-value on a graph there is a larger y-value. Decay is when numbers decrease rapidly in an exponential fashion so for every x-value on a graph there is a smaller y-value. So here the one that fits the description is A.

Answer:
Rs 2.25
Step-by-step explanation:
S.P. = 375 * 3.36 = 1260
C.P. = 1125. for 500 mangoes
So for 1 mango,
C.P. = Rs 2.25
Answer:
₹2.25
Step-by-step explanation:
Selling price of 1 mango = ₹3.36
Mangoes in good state = 500 - 125 = 375
Selling price of 375 mangoes = 3.36 *375 = ₹ 1260
Cost price = [tex]\frac{100}{100+profit}*SP[/tex]
[tex]= \frac{100}{100+12}*1260\\\\=\frac{100}{112}*1260\\\\= 1125[/tex]
Cost price of 500 mangoes = ₹ 1125
CP of 1 mango = 1125/500 = ₹2.25
La sombra de un árbol cuando los rayos del sol forman con la horizontal un ángulo de 36º, mide 11 metros. ¿Cuál es la altura del árbol?
Answer:
La altura del árbol es 8 metros.
Step-by-step explanation:
La sombra de un árbol, cuando los rayos del sol forman con la horizontal un ángulo de 36º, mide 11 metros. Esto se puede observar en la imagen adjunta.
La trigonometría estudia la relación entre los lados y ángulos de los triángulos. Las razones trigonométricas de un ángulo α son las razones obtenidas entre los tres lados de un triángulo rectángulo (uno de sus ángulos es recto y mide 90°).
La tangente de un ángulo es la razón entre el cateto opuesto y el cateto contiguo o cateto adyacente. En este caso se debe aplicar dicha relación trigonométrica.
[tex]tan(\alpha )=\frac{cateto opuesto}{cateto adyacente}[/tex]
En este caso, se conoce el ángulo, cuyo valor es 36°, y el cateto adyacente, cuyo valor es 11. Reemplazando:
[tex]tan(36 )=\frac{cateto opuesto}{11}[/tex]
Resolviendo:
cateto adyacente= tan(36)*11
cateto adyacente= 7.99 metros ≅ 8 metros
La altura del árbol es 8 metros.

Según la gráfica cuadrática de la expresión y= x² + 1 ¿Cuales serían las coordenadas cuando x es igual a -2,-1 y 0?
Answer:
When x = -2 P ( -2 ; 5)
When x = -1 Q ( -1 ; 2)
When x = 0 R ( 0 ; 1)
Step-by-step explanation:
y = x² + 1
When x = -2
y = ( -2)² + 1 y = 5 point P ( -2 ; 5)
When x = - 1
y = ( -1)² + 1 y = 2 point Q ( -1 ; 2 )
When x = 0
y = (0)² + 1 y = 1 point R ( 0 ; 1 )

Find the value of 1×4+2×5+3×6......n×（n+3）
Answer:
n(n+1)(n+5)/3
Step-by-step explanation:
there is no value, as we don't know n.
but we can create a summary formula/ function definition :
this is the sum for k = 1 to n of k×(k+3)
k×(k+3) = k² + 3k
so, the overall sum splits into the sum of k² for k=1 to n, and the sum of 3k for k=1 to n.
and the sum of 3k is 3 times the sum of k for k=1 to n.
Σk² for k=1 to n = [n(n+1)(2n+1)]/6
Σk for k=1 to n = n(n+1)/2
3×Σk for k=1 to n = 3×n(n+1)/2
so, we have a function formula
n(n+1)(2n+1)/6 + 3n(n+1)/2 = n(n+1)(2n+1)/6 + 9n(n+1)/6 =
= n(n+1)(2n+1+9)/6 = n(n+1)(2n+10)/6 = n(n+1)(n+5)/3

Answer:
angle 3 = 79 degree
Step-by-step explanation:
given:
angle 1 = 98 degree
angle 2 : 19 degree
angle 3 =?
angle 2 + angle 3 =angle 1 (sum of two interior angle opposite angles is equal to the exterior angle formed)
19 + angle 3 = 98
angle 3 = 98 - 19
angle 3 = 79 degree
