Step-by-step explanation:
Angel is running for school council president. He receives 300 votes, which is 60% of all the votes. How many students vote in the election?
Angel receives 300 votes which is 60% of total votes.
Therefore we can determine 60% = 300
The next thing to do would be to determine 1% and we can do this by dividing both sides by 60:
60% = 300
1% = 5
Then multiply both sides by 100 to determine 100% of total votes (total amount of students who voted):
1% = 5
100% = 500
Therefore 500 students voted in the election.
Answer:
500 students
Step-by-step explanation:
300=60%
300x2=600
(turning the 300 into 600 helps it make sense)
600/3=200
200x5= 1000
1000/2=500

write in simplest form
14a^2 / 24a
Answer:
The simplest form of [tex]\frac{14a^2}{24a}[/tex] is [tex]\mathbf{\frac{7a}{12}}[/tex]
Step-by-step explanation:
We need to write [tex]\frac{14a^2}{24a}[/tex] in simplest form.
We know the exponent rule: [tex]\frac{a^m}{a^n}=a^{m-n}[/tex]
Applying the rule:
[tex]\frac{14a^2}{24a} \\=\frac{14a^{2-1}}{24}\\Since \ 14 \ and \ 24 \ are \ divisible\ by \ 2 \\=\frac{7a^1}{12} \\=\frac{7a}{12}[/tex]
The simplest form of [tex]\frac{14a^2}{24a}[/tex] is [tex]\mathbf{\frac{7a}{12}}[/tex]

Step-by-step explanation:
34x+85=3(13x+7)
Step 1: Simplify both sides of the equation.
34x+85=3(13x+7)
34x+85=(3)(13x)+(3)(7)(Distribute)
34x+85=39x+21
Step 2: Subtract 39x from both sides.
34x+85−39x=39x+21−39x
−5x+85=21
Step 3: Subtract 85 from both sides.
−5x+85−85=21−85
−5x=−64
Step 4: Divide both sides by -5.
−5x/−5=−64/−5
x=64/5

The fuel tank of a cruise ship holds 28,665 barrels of gasoline. A fuel tank hold 5,312 barrels of gasoline. Can 5 fuel tankers fuel fill the cruise ship's tank?
Answer:
No
Step-by-step explanation:
Given that :
Fuel tank of cruise ship hold 28,665 barrels
Capacity of fuel tanker = 5312 barrels
Can 5 fuel tankers fuel fill the cruise ship's tank?
5 * capacity of fuel tanker
5 * 5312 = 26,560 barrels
No because 28665 > 26560

surface area = 2 (LW + LH + WH)
a)
where L = length = 8
W = width = 2
H = height = 2
plugin values into the formula:
surface area = 2 (8*2 + 8*2 + 2*2)
= 2 (16 + 16 + 4)
= 72
---
b)
where L = length = 2
W = width = 3
H = height = 9
plugin values into the formula:
surface area = 2 (2*3 + 2*9 + 3*9)
= 2 (6 + 18 + 27)
= 102
---
c)
surface area = 2(area of rectangular side) + 2(area of triangular side) + base area
plugin values into the formula:
surface area = 2 (2*7) + 2( 1/2 * 7 * 6.1) + (2*7)
= 28 + 42.7 + 14
= 84.7

On Saturday, Carrie went to the store and bought 4 loaves of bread and 1 gallon of milk for a total of $12.50. The next weekend, she went to the same store and spent $11.50 on 2 loaves of bread and 2 gallons of milk. The prices had not changed. What is the price for one gallon of milk?
Answer:
The price of one gallon of milk is $3.5
Step-by-step explanation:
x----> the price of one loaves of bread
y----> the price of one gallon of milk
we know that
4x+y=12.50 ----> equation A
2x+2y=11.50 ----> equation B
Solve the system of equations by graphing
Remember that the solution of the system of equations is the intersection point both graphs
The solution is the point (2.25,3.5)
see the attached figure
therefore
The price of one loaves of bread is $2.25
The price of one gallon of milk is $3.5

La suma de las edades de un padre y sus dos hijos es de 48 dentro de 10 años el doble de la suma de las edades de los hijos excederá en 6 años a las edades del padre cuando nacio el pequeño la edad del padre accedia 26 unidades al triple de la edad que tenia el hijo mayor cual es la edad de los 3
Answer:
La edad del padre es 40 años, la edad del hijo menor es 2 años y la del hijo mayor es 6 años.
Step-by-step explanation:
Un sistema de ecuaciones lineales es un conjunto de ecuaciones lineales que tienen más de una incógnita. Las incógnitas aparecen en varias de las ecuaciones, pero no necesariamente en todas, y se relacionan mediante las ecuaciones. En otras palabras, un sistema de ecuaciones es un conjunto de dos o más ecuaciones con varias incógnitas en la que desea encontrar una solución común, es decir, encontrar el valor de cada incógnita para que se cumplan todas las ecuaciones del sistema.
En este caso debes resolver una sistema de ecuaciones, para lo cual debes en primer lugar definir las variables a utilizar:
x: edad del padre y: edad del hijo mayor z: edad del hijo menorEntonces, siendo:
La suma de las edades de un padre y sus 2 hijos es 48. Dentro de 10 años el doble de la suma de las edades de los hijos excederá en 6 años a la edad del padre. Cuando nació el pequeño la edad del padre excede 26 unidades al triple de la edad que tenía el hijo mayor.Se puede expresar simbólicamente como:
x +y +z= 48 Ecuación 12*[(y+10) + (z+10)]= (x+10) + 6 Ecuación 2(x-z)= 3*(y-z) +26 Ecuación 3que será el sistema de ecuaciones a resolver.
Para resolver se puede usar el método de sustitución, que consiste en despejar o aislar una de las incógnitas (por ejemplo, x ) y sustituir su expresión en la otra ecuación para así ir determinando el valor de cada una de las variables.
En este caso, despejando el valor de x de la ecuación 1 se obtiene:
x= 48 -y -z Ecuación 4
Reemplazando esta expresión en la ecuación 2:
2*[(y+10) + (z+10)]= (48 -y -z+10) + 6
y aislando la variable y obtienes:
2*[y + z +10 +10]= 48 -y -z +10 +6
2*[y + z +20]= 64 -y -z
2*y + 2*z +40= 64 -y -z
2*y + y= 64 -z -2*z -40
3*y= 24 - 3*z
y= (24 - 3*z)÷ 3
y= 8 - z Ecuación 5
Reemplazando esta expresión en la ecuación 4:
x= 48 - (8 -z) -z
y resolviendo se obtiene el valor de x, es decir, la edad del padre:
x= 48 -8 +z +z
x=40
Entonces, la edad del padre es 40 años.
Ahora, reemplazando la ecuación 5 y el valor de x en la ecuación 3 se obtiene:
(40-z)= 3*(8 -z -z) +26
Resolviendo:
40 -z= 3*(8 -2*z) +26
40 -z= 3*8 - 3*2*z +26
40 -z= 24 -6*z +26
-z + 6*z= 24 + 26 - 40
5*z= 10
z= 10÷ 5
z=2
Entonces, la edad del hijo menor es 2 años.
Finalmente, reemplazando el valor de z en la ecuación 5 se obtiene:
y= 8 - 2
y= 6
Por lo que, la edad del hijo mayor es 6 años.

I had this question on a test
Mateo has been studying after school while preparing for a test retake. His work paid off ! His score on the retake was a 94. This was quite a difference from the grade on his first attempt which was a 68. What is the approximate percent of change between the two tests?
Answer:
28%
Step-by-step explanation:
We know that 100 percent is total. Mateo first scored 68/100, then a retake got his score up to 94/100.
First, subtract the two numbers
94 - 68 = 26
Put 26 over 94 to make this 26/94
Divide to get 0.28 (simplified and rounded)
So the increase was 28%
Answer:
increase of 28?
Step-by-step explanation:
Okay so, I believe it is 28, let me explain. First, work out the difference (decrease) between the two numbers you are comparing. Next, divide the decrease by the original number and multiply the answer by 100. If the answer is a negative number, this is a percentage increase.
