3 -4. Litros d jugo de frutilla 1 y 1-2 litro de jugo de manzana 1-8 litro de jugo de limón Y 1 y 1-2 litro de agua .Cuántos litros de jugo preparo la mamá??
Answer:
La madre hizo en total 2 y 3/8 litros de jugo.
Step-by-step explanation:
Sabemos que preparó:
3/4 litros de jugo de frutilla = 3/4 L
1 y 1/2 litro de jugo de manzana = (1 + 1/2) L
1/8 litro de jugo de limón = 1/8 L
1 y 1/2 litro de agua = (1 + 1/2) L
¿Cuántos litros de jugo preparó la mamá?
Simplemente debemos sumar los distintos volúmenes de jugo escritos arriba (el de agua no, pues solo nos pregunta cuantos litros de jugo se prepararon)
Total de jugo = 3/4 L + (1 + 1/2) L + 1/8 L
Para completar esta suma, separamos los números enteros de los racionales:
Total de jugo = 1 L + ( 3/4 + 1/2 + 1/8) L
Para resolver la suma dentro del paréntesis, debemos tener todos los números con el mismo denominador.
Recordar que si multiplicamos el numerador y el denominador por el mismo número, entonces el número racional no cambia.
Como el denominador más grande dentro del paréntesis es 8 (que tambien es multiplo de los otros dos), tratemos de reescribir los otros dos números de tal forma que su denominador también sea 8:
Total de jugo = 1 L + ( (2/2)*(3/4) +(4/4)*(1/2) + 1/8) L
= 1 L + (6/8 + 4/8 + 1/8) L
= 1 L + (11/8) L
podemos reescribir el segundo termino como:
= 1L + (8 + 3)/8 L
= 1L + (8/8) L + (3/8) L
= 1L + 1L + 3/8 L
= 2L + 3/8 L
La madre hizo en total 2 y 3/8 litros de jugo.

What is the image of the point(2,-5) after a rotation of 90 degree counterclockwise about the origin
Answer:
(-2,5)
Step-by-step explanation:
When a point is rotated counterclockwise 90 degrees about the origin then the coordinates of the image will be (x,y) → (-y,x).
Here, (5,2)→(-2,5)
Therefore , if (5,2) is rotated counterclockwise 90 degrees about the origin its image will be point (-2,5).
Hence, if (5,2) is rotated counterclockwise 90 degrees about the origin its image will be point (-2,5).

A map has a scale of 1:200000 How far is it from Belfast to Larne in Km if the distance on the map is 7.8cm
Answer:
15.6km
Step-by-step explanation:
Given the map scale 1:200000
1cm on the map represents 200000 cm on ground or in actual distance
Hence, if distance from Belfast to Larne is 7.8vm on map ;
Actual distance will be :
7.8 * 200000 = 1560000 cm
Converting to km :
Recall :
1000 m = 1km
100 cm = 1 m
Hence,
100000 cm = 1km
Therefore, (1560000 / 100000) km
= 15.6km
Hence, distance between Belfast and Larne is 15.6km

Assuming two hikers begin at a trail start, which scenarios must be true based on the table? Check all that apply. Melissa and Corey started on different trails. Melissa hiked up the trail for a longer period of time than Corey. Melissa and Corey crossed paths between 60 and 90 minutes. Corey began his descent before Melissa. As Melissa’s time increased from 0 to 60 minutes, her elevation decreased.
Answer:
1. Melissa and Corey started on different trails.
2. Melissa hiked up the trail for a longer period of time than Corey.
3. Melissa and Corey crossed paths between 60 and 90 minutes.
4. Corey began his descent before Melissa.
Step-by-step explanation:
A. Melissa and Corey started on different trails. - TRUE
Rationale: at the start, when t = 0, Melissa hiking trail elevation was 8,342 ft while that of Corey was 10,004 ft. Therefore, they started on different trails.
B. Melissa hiked up the trail for a longer period of time than Corey. - TRUE
Rationale: It took Melissa 90 mins to reach the highest elevation of 12,921 while it took just 60 mins for Corey to teach same elevation height at 60 mins
C. Melissa and Corey crossed paths between 60 and 90 minutes. - TRUE
Rationale: As Melissa was still ascending between 60 - 90 mins from 11,239 to 12,921, Corey was descending at the same time . So their path crossed.
D. Corey began his descent before Melissa. - TRUE
Rationale: Corey started descending earlier at 60 mins before Melissa
E. As Melissa’s time increased from 0 to 60 minutes, her elevation decreased. - FALSE
Rationale: as Melissa's time increased from 0 to 60 mins, her elevation increased also from 8,342 ft to 11,239 ft.
Answer:
A) Melissa and Corey started on different trails.
B) Melissa hiked up the trail for a longer period of time than Corey.
D) Corey began his descent before Melissa.

Samuel, Martín y Santiago salen a montar bicicleta de Cali hacia Palmira. La distancia entre Cali y Palmira es de 29.3 KM. En la siguiente tabla se muestra los km que lograron realizar cada uno. Samuel izo 178/8 km , martin 21 3/4 km y santiago 21 5/12 ¿Quien recorrio mas distancia? ¿Cuantos km les falto a cada uno para llegar a palmira? ¿en promedio cuantos km recorrieron entre los 3 amigos? ¿¿Cuántos kilometros recorrió más Martín que Santiago? AYUDDAAAAAAAAaaaaaaa
Answer:
a) Martín recorrió más distancia, b) A Samuel, Martín y Santiago les falta 7.05, 7.55 y 7.883 kilómetros, respectivamente, c) La distancia recorrida promedio es 21.889 kilómetros, d) Martín recorrió 0.333 kilómetros más que Santiago.
Step-by-step explanation:
a) En primer lugar, convertimos la distancia recorrida por cada persona a su forma decimal:
Samuel
[tex]\frac{178}{8}\,km = 22.25\,km[/tex]
Martin
[tex]21\,km + \frac{3}{4}\,km = 21.75\,km[/tex]
Santiago
[tex]21\,km + \frac{5}{12}\,km = 21.417\,km[/tex]
Como puede apreciarse, Martín recorrió más distancia.
b) La distancia faltante es igual a la sustracción de la distancia recorrida por la persona a la distancia total:
Samuel
[tex]x = 29.3\,km -22.25\,km[/tex]
[tex]x = 7.05\,km[/tex]
Martin
[tex]x = 29.3\,km - 21.75\,km[/tex]
[tex]x = 7.55\,cm[/tex]
Santiago
[tex]x = 29.3\,km - 21.417\,km[/tex]
[tex]x = 7.883\,km[/tex]
A Samuel, Martín y Santiago les falta 7.05, 7.55 y 7.883 kilómetros, respectivamente.
c) La distancia recorrida promedio se obtiene sumando las distancias recorridas de las tres personas y dividiendo el resultado por la cantidad de personas:
[tex]\bar{x} = \frac{22.5\,km + 21.75\,km + 21.417\,km}{3}[/tex]
[tex]\bar x = 21.889\,km[/tex]
La distancia recorrida promedio es 21.889 kilómetros.
d) Esta diferencia se encuentra a restar la distancia recorrida por Santiago a la distancia recorrida por Martín:
[tex]x = 21.75\,km - 21.417\,km[/tex]
[tex]x = 0.333\,km[/tex]
Martín recorrió 0.333 kilómetros más que Santiago.

Step-by-step explanation:
If using the method of completing the square to solve the quadratic equation x^2-5x-18=0x 2 −5x−18=0, which number would have to be added to "complete the square"?
Answer:
25/4 will have to be added to "complete the square"
Step-by-step explanation:
x² - 5x - 18 = 0
x² - 5x = 18
Find the half of the coefficient of x and square it
(5/2)² = 25/4
Add 25/4 to both sides to complete the square
x² - 5x + 25/4 = 18 + 25/4
x² - 5x + 25/4 = 18(4/4) + 25/4
x² - 5x + 25/4 = 72/4 + 25/4
x² - 5x + 25/4 = (72+25)/4
x² - 5x + 25/4 = 97/4
(x - 5/2)² = 97/4
Find the square root of both sides
√(x - 5/2)² = ±√97/4
x - 5/2 = √97/2
x = √97/2 + 5/2 or x = -√97/2 + 5/2
x = 7.42443 or -2.42443
A delivery man can deliver 91 packages in 2 hours. If he continues at this rate, how many packages can the delivery man deliver in 8 hours?
==============================================
Work Shown:
(91 packages)/(2 hours) = (x packages)/(8 hours)
91/2 = x/8
91*8 = 2*x .... cross multiply
728 = 2x
2x = 728
x = 728/2 .... divide both sides by 2
x = 364
-----------------
Another approach:
If he delivers 91 packages in 2 hours, then his unit rate is 91/2 = 45.5 packages per hour. Multiply this by the 8 hours
8*45.5 = 364

Answer:
x = 12
Step-by-step explanation:
Angle 1 = 8x - 17
Angle 2 = 5x + 19
These are congruent which means they are the same so the equation is:
8x - 17 = 5x + 19
3x - 17 = 19
3x = 36
x = 12
Answer:
last option is correct
Step-by-step explanation:
8x-17=5x+19(being corresponding angles)
8x-5x=19+17
3x=36
x=36/3
x=12

Laura wants to place one flowerpot every meters along the path from the gate to the main entrance of her home. The path is meters long. How many flowerpots will she need?
Answer:
16 flower pots
Step-by-step explanation:
Length of path = 12 m long
Flower pot is placed every 3/4 m along the path ;
Number of flower pots required = (length of path / length of distance placed)
Number of flower pots required = 12 ÷ 3/4
12 * 4/3 = (12 * 4) / 3 = 48 / 3 = 16 flower pots
