Help!! Solve 1 1/4 + 5 5/6
Answer:
7 2/24
Step-by-step explanation:
We can start by making the denominators the same (the bottom number)
1 1/4+5 5/6
1 6/24+ 5 20/24=7 2/24
Answer:
so what you would want to do is get your fraction into improper fractions and to do that you multiply the whole number by the denominator and add it to your numerator, once you do that you get 5/4, and 35/6, now we want to get common denominators, so we multiply 5/4, by 6/6, and 35/6 by 4/4 which would get us 30/24 and 140/24 then we add them and get 170/24 and then simplify, which gets you 85/12 and then put it into a mixed number which is 7 1/12

If the buses run on schedule, when is the next time a red line and a blue line bus will leave together? Show your work.
Answer:
So the next time they will leave together is 4:24 pm
Step-by-step explanation:
Since both the buses left at 4 pm and red line bus leaves every 6minutes and blue line bus leaves every 8 minutes they next time they leave together can be found by taking the L.C. M of 6 and 8.
The L.C. M is found by multiplying all the factors and chosing one which common in both numbers.
Factors of 6 = 2*3
Factors of 8= 2*2*2
In these numbers 2 is common in both.The rest of the numbers( 2*2*3 )are multiplied with the the common 2 to get the L.C.M
L.C.M= 2*2*2*3= 24 minutes
So the next time they will leave together is 4:24 pm
Brianne's town is building a pool based on a scale drawing that is 20 centimeters by 10 centimeters and uses the scale 1 cm:250 cm. What is the area of the pool in square meters? Enter the area of the pool in the box.
Answer:
[tex]A=1250m^2[/tex]
Step-by-step explanation:
From the question we are told that
Dimension of drawing
20 centimetres by 10 centimetres
Scale of drawing
1 cm:250 cm
Generally the the Main dimension of the pool is mathematically given as
[tex]L=length\ of\ scaled\ pool*250 cm\\B=length\ of\ scaled\ pool*250 cm\\L=20*250=5000 cm=50m\\B=10*250=2500 cm=25m[/tex]
Therefore Area Aof main pool is mathematically given as
[tex]A=50m*25m=1250 m^2[/tex]
[tex]A=1250m^2[/tex]

Determina el perimetro de las figuras geometricas que forman la rayuela
Perimetro: L=50 cm
Expresión:
Sustitucion:
P=_______/
La figura es un cuadrado y cada lado mide 50 cm
Answer:
2000cm
Step-by-step explanation:
Rayuela es un juego jugado por niños que se compone de 10 cuadrados.
Se nos da a partir de la pregunta anterior, la longitud del lado de un cuadrado = 50 cm
La fórmula para el perímetro de un cuadrado es 4a
Donde a = longitud del lado
El perímetro de 1 cuadrado =
4 × 50 cm
= 200cm
El perímetro de los cuadrados totales en la rayuela.
1 cuadrado = 200 cm
10 cuadrados = x
Multiplicar cruzada
x = 10 × 200 cm
x = 2000 cm
Por lo tanto, el perímetro de las figuras geométricas de una rayuela = 2000cm.
A café has a monthly fixed cost of $4700, and a typical customer order costs the café $2. Therefore, the cost to serve x customers in a month is given by x = 4,700 + 2x. The typical order costs $10. So revenue is y = 10x. Find the number of customers that would need to come in the café for the company to break even. (Intersection point)
Answer:
The number of customers that would need to come in the café for the company to break even is 470.
Step-by-step explanation:
Given
Revenue = y = 10x ……………….…. (1)
Cost = x = 4,700 + 2x ……………… (2)
Since the company will break even when Revenue is equal to Cost, we therefore equate equations (1) and (2) and then solve for x as follows:
10x = 4,700 + 2x
10x - 2x = 4,700
x = 4,700 / 10
x = 470
Therefore, the number of customers that would need to come in the café for the company to break even is 470.
7. A triangle has side lengths of 9 and 5. Which of the following cannot be the length of the third side? *
The values less than 4 or greater than 14 cannot be the length of the third side
Which cannot be the length of the third side?From the question, we have the following parameters that can be used in our computation:
Side lengths of 9 and 5.
Represent the third length of the triangle with x
So, we have the following representation (using the triangle inequality theorem)
a + b ≥ c.
Substitute the known values in the above equation, so, we have the following representation
9 + 5 ≥ x
9 + x ≥ 5
5 + x ≥ 9
Evaluate the sum
14 ≥ x
x ≥ -4
x ≥ 4
So, we have
14 ≥ x
x ≥ 4
Combine
4 ≤ x ≤ 14
This means that values less than 4 or greater than 14 cannot be the length of the third side

The measure that cannot be the length of the third side is 14. Option
How to determine the lengthAn important rule to remember about triangles is called the third side rule:
Third side rule of triangles states that;
The length of the third side of a triangle is less than the sum of the lengths of the other two sides and greater than the (positive) difference of the lengths of the other two sides.
For this triangle, the length of the third side must be greater than
9- 5= 4
Also, the length of the third side must be less than
9 + 5 = 14
Hence, all the answers are possible except for answer D, which is equal to 14 but not less than 14.

Question 12 (2 points)
Solve the system of equations using subsititution.
y = 2x - 3
y + 5 = 3x
Answer:
(2,1)
x = 2
y = 1
Explanation:
Check the image
Answer:
(2,1)
Step-by-step explanation:
Since we already have an equation for y, all we need to do is plug that into y in the other equation.
y + 5 = 3x
(2x - 3) + 5 = 3x
2x - 3 + 5 = 3x
2x + 2 = 3x
2 = x
Now that we know y, we just need to plug the value of x into the equation.
y = 2(2) - 3
= 4 - 3
= 1

Uno se pierde, el otro se recicla.
Explicación:
El movimiento de nutrientes difiere del flujo de energía en un ecosistema porque los nutrientes se pueden reciclar mientras que, por otro lado, la energía se pierde en el ecosistema. Tanto los nutrientes como la energía fluyen en la misma dirección y toda la energía del ecosistema proviene del sol, que es la principal fuente de energía. Entonces podemos decir que la energía perdida y los nutrientes se reciclan en el ecosistema.
