The value of x in the proportion below is option 1 3 1/2.
What is butterfly method?When using the butterfly method approach, the denominator of the first term is multiplied by the numerator of the second term, and vice versa.
What is proportion?An equation known as proportion shows that the two ratios presented are equal to one another. In other terms, the proportion declares that the two ratios or fractions are equal. In terms of proportion, two sets of supplied numbers are said to be directly proportional if they increase or decrease in the same ratio.
The given proportion is:
[tex]\frac{\frac{1}{2} }{4} = \frac{x}{28}[/tex]
Using the method of cross-product or butterfly method:
[tex]\frac{\frac{1}{2} (28) }{4}=x \\\\\frac{14}{4}=x\\ \\x=3.5[/tex]
The value of x is 3.5. Converting this value into mixed fraction:
3.5 = 3 1/2
Hence, the value of x in the proportion below is option 1 3 1/2.

if 1/2 gallon of paint covers 1/12 of a wall,then how many quarts of paint are needed for the entire wall
Answer: 4
Step-by-step explanation: there is 4 quarts in a gallon so 1/2 gallon is 2 quarts. 2x2=4
Answer:
6 gallons which is 24 quarts
Step-by-step explanation:
because while covering 2/12ths of a wall you used a whole gallon of paint so if 1 gallon covers 2/12ths of a wall you have 10/12ths left and s you already used 1 so it would leave you with 5 gallons and 10 divided by 2 is 5 which would give you your answer 6 gallons and there are 4 quarts in a gallon so you would multiply 6 *4 = 24
Is the number 65.4349224... rational or irrational? Explain.

It is irattional because the number keeps changing
Step-by-step explanation:
Answer:
my guess is irrational
Step-by-step explanation:
A rational number is a number that can be express as the ratio of two integers. A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever).
Jessie paid $43.75 for 5 movie tickets. Each ticket cost the same amount. What was the cost of each movie ticket in dollars and cents?
Answer:
$8.75
Step-by-step explanation:
Divide $43.75 by 5 to get the cost of ONE movie ticket like so:
$43.75 / 5 movie tickets = $8.75 per ticket.
Therefore, ONE ticket costs $8.75.
Jose takes 120 minutes to weed 6 equal rows of vegetable plants in his garden. What is his unit rate
Answer:
20 minutes per row
Step-by-step explanation:
Divide the total time by the total number of rows to find the amount of time for one row
6r= 120
Divide each side by 6 to isolate the variable (r= number of rows)
r= 20
what is x ?
what is y ?
Answer:
y = 100° , x = 80°
Step-by-step explanation:
Two angles on a straight line equal 180°. Therefore, 80° + y = 180°. This means y = 100°.
80° and x are alternate exterior angles. Using that property, we know those angles are congruent. This means x is also 80°.

Tavon has a gist card for $145 that losses $3.50 for each 30-day period is not used. He has another gift card for $125 that losses $3 for each 30-day period it is not used. A. Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal. B. What will the value of each card be when they have equal value?
Step-by-step explanation:
A. For Tavon's gift card the equation is
let y be the total amount
let x be the number of 30 day period
y=145-3.5x------1
for Tavon's second gift card the equation is
let y be the total amount
let x be the number of 30 day period
y=125-3x-------------2
B. equating 1 and 2 we have
145-3.5x=125-3x
solve for x we have
145-125=-3x+3.5x
20=0.5x
divide both sides by x we have
x=20/0.5
x= 40
put x=40 in
y=145-3.5*40------1
y=145-140
y=$5
put x=40 in
y=125-3*40------1
y=125-120
y=$5

Hope I Helped! :)
Answer:
The solution is C. -10
Step-by-step explanation:
Before entering the solution, remember the formula first!
Addition
• (-) + (-) = (-)
• (+) + (+) = (+)
Subtraction
• (+) - (+) = can (-) and (+)
• (+) - (-) = (+)
Multiplication
• (-) x (-) = (+)
• (+) x (-) = (-)
Division
• (-) : (-) = (+)
• (+) : (-) = (-)
Solution:
(-90) + (-20) + 100
= -90 - 20 + 100
= -110 + 100
= -10 (the minus number is greater than the positive, then the result is minus)
Una tienda compra pendrive de diferentes
colores al por mayor, para navidad hizo un
pedido extraordinario de 84 memorias rojas, 196 azules y 252 verdes. Para guardar la
mercancía de forma organizada, exigió que
le enviarán las memorias en cajas iguales,
sin mezclar los colores y conteniendo el mayor número posible de memorias.
Answer:
En síntesis, se requiere utilizar cajas con capacidad para 28 memorias. Al no mezclarse los colores, requerimos utilizar 3 cajas para las memorias rojas, 7 cajas para las memorias azules y 9 cajas para las memorias verdes.
Step-by-step explanation:
La cantidad de cajas es igual a la cantidad de memorias dividida por la capacidad de una caja. Al indicarse que las memorias serán guardadas en cajas de igual capacidad, sin mezclar los colores y con el mayor número posible de artículos, podemos utilizar el concepto de máximo común divisor, cuyo procedimiento mostramos a continuación:
(i) Realizamos la descomposición factorial de cada número:
Memorias rojas:
[tex]84 = 2\times 2 \times 3\times 7[/tex]
Memorias azules:
[tex]196 = 2\times 2\times 7\times 7[/tex]
Memorias verdes:
[tex]252 = 2\times 2\times 3 \times 3 \times 7[/tex]
(ii) Hallamos los números primos en común que tiene cada colección de memorias:
[tex]S=\{2,2,7\}[/tex]
(iii) Calculamos el máximo común divisor al multiplicar los elementos del conjunto S:
[tex]M.C.D. = 2\times 2\times 7[/tex]
[tex]M.C.D. = 28[/tex]
Esto quiere decir que cada caja debe llevar 28 memorias del mismo color. Finalmente, calculamos la cantidad requerida de cajas para cada memoria.
Memorias rojas:
[tex]n_{R} = \frac{84}{28}[/tex]
[tex]n_{R}= 3[/tex]
Memorias azules:
[tex]n_{A} = \frac{196}{28}[/tex]
[tex]n_{A} = 7[/tex]
Memorias verdes:
[tex]n_{V} = \frac{252}{28}[/tex]
[tex]n_{V} = 9[/tex]
En síntesis, se requiere utilizar cajas con capacidad para 28 memorias. Al no mezclarse los colores, requerimos utilizar 3 cajas para las memorias rojas, 7 cajas para las memorias azules y 9 cajas para las memorias verdes.

Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
So first you have to plug in what you know...
[tex]3x+y>3\\3(\frac{3}{4})+(0)>3\\\frac{9}{4}+0>3\\\frac{9}{4} >3[/tex]
If it's hard to look at it that way you should make it look like this...
[tex]2\frac{1}{4} >3[/tex]
Now when you look at it you can tell that it's false, so [tex](\frac{3}{4},0 )[/tex] is not a solution f this inequality.

Step-by-step explanation:
A cab charges $1.45 for the flat fee and $0.55 for each mile. Write and solve an inequality to determine how many miles Ariel can travel if she has $35 to spend.
answers are:
A. $1.45 + $0.55x ≥ $35; x ≥ 61 miles
B. $1.45 + $0.55x ≤ $35; x ≤ 61 miles
C. $0.55 + $1.45x ≥ $35; x ≥ 23 miles
D. $0.55 + $1.45x ≤ $35; x ≤ 23 miles
9514 1404 393
Answer:
B. $1.45 + $0.55x ≤ $35; x ≤ 61 miles
Step-by-step explanation:
The mileage charge for x miles will be $0.55x, so the total charge will be $1.45+$0.55x. This must be less than or equal to $35 for Ariel to be able to pay for her travel. The appropriate inequality is ...
$1.45 +$0.55x ≤ $35 . . . . . matches choice B
__
Comment on selecting an answer
From a "reasonableness" point of view, any answer choice with "≥ $35" can be eliminated immediately. Further, any answer choice with $1.45x can be eliminated, since the mileage charge is not $1.45, it is $0.55. The leaves only the choice shown above.
A magician charges parties a $30 fee to cover travel and other expanses plus $19.99 per hour. Write an equation to represent the relationship between x, the number of hours, and y, the total charge for the magician.
Answer:
y = 19.99x + 30Step-by-step explanation:
one time charge of $30
plus $19.99 per hour
let x be the number of hour
and y be the total charge of the magician.
therefore, the equation would be:
y = 19.99x + 30
