HURRY PLEASE When 5 and 6 are multiplied by the same factor, how do the ratios compare to the ratio 5:6? The ratios are equivalent to 5:6. The ratios are equivalent to 6:5. The ratios are greater than 5:6, as the factors become greater. The ratios are greater than 6:5, as the factors become greater.
Answer:
The ratios are equivalent.
Step-by-step explanation:
If you multiply both 5 and 6, the ratio stays the same.
5:6 = 10:12 = 15:18 = 20:24 etc.
You can try this by dividing the larger number by the smaller number. You'll always get 1.2 as the "relationship", or ratio, is preserved.
24/20 = 1.2
15/18 = 1.2
10/12 = 1.2
6/5 = 1.2

9:25 y 33:41:38 a que unidades de tiempo se refieren?
Answer:
Se refieren a las unidades de tiempo del sistema sexagesimal
9:25 son 9 minutos y 25 segundos
33:41:38 son 33 horas, 41 minutos y 38 segundos.
Step-by-step explanation:
El sistema sexagesimal se utiliza para medir tiempos y ángulos.
El tiempo se mide en horas,minutos y segundos
En cambio, los ángulos se miden en grados,minutos y segundos.
Los dos puntos '':'' sirven para separar las unidades.
La base de este sistema es el número 60 :
60 segundos ⇒ 1 minuto
60 minutos ⇒ 1 hora
Eso en cuanto a tiempo
En cuanto a grados :
60 segundos ⇒ 1 minuto
60 minutos ⇒ 1 grado
Cuando tengo dos números como en 9:25 , el número de la derecha corresponde a los segundos y el de la izquierda a los minutos
Entonces, 9:25 son 9 minutos y 25 segundos
Por otro lado, cuando tengo 3 números, como en 33:41:38, el número de la derecha corresponde a los segundos, el de en medio al de los minutos y el de la izquierda al de las horas (si nos referimos a unidades de tiempo).
Entonces, 33:41:38 son 33 horas, 41 minutos y 38 segundos.

Aaron’s age is three years less than Devon‘s age the sum of their ages is 31 find each of their ages
Aaron 14 years
Devon 17 years
Step-by-step explanation:D = A + 3
D + A = 31
replace D
A + 3 + A = 31
2A = 31 - 3
2A = 28
A = 14 years
D = 17 years
A music company sells CDs for a particular artist. The company has advertising cost of $4,000 and recoding costs of $10,000; Their cost for manufacturing, royalties, and distribution are $5.50 per CD. They sell the CDs to Mage-Mart for $7.20 each
Answer:
Instructions are below.
Step-by-step explanation:
Giving the following information:
Fixed costs= 4,000 + 10,000= $14,000
Unitary variable cost= $5.5
Selling price= $7.2
To calculate the number of units to be sold to break-even, we need to use the following formula:
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 14,000 / (7.2 - 5.5)
Break-even point in units= 8,235 units
In dollars:
Break-even point (dollars)= fixed costs/ contribution margin ratio
Break-even point (dollars)= 14,000 / (1.7/7.2)
Break-even point (dollars)= $59,294
Now, imagine the company requires a profit of $50,000:
Break-even point in units= (fixed costs + desired profit) / contribution margin per unit
Break-even point in units= 64,000/1.7
Break-even point in units= 37,647 units
Break-even point (dollars)= (fixed costs + desired profit) / contribution margin ratio
Break-even point (dollars)= 64,000 / (1.7/7.2)
Break-even point (dollars)= $271,059

2(n+2)=4n+1-2n
Whats the answer
Answer:
no solution
Step-by-step explanation:
Given
2(n + 2) = 4n + 1 - 2n ← distribute parenthesis on left side
2n + 4 = 2n + 1 ( subtract 4 from both sides )
2n = 2n - 3 ( subtract 2n from both sides )
0 = - 3 ← not possible
This indicates the equation has no solution
The original equation 2(n + 2) = 4n + 1 - 2n has no solution for n.
To solve the equation 2(n + 2) = 4n + 1 - 2n, we can simplify and then solve for the variable n.
First, distribute 2 to the terms inside the parentheses:
2n + 4 = 4n + 1 - 2n
Next, combine like terms on the right side:
2n + 4 = 2n + 1
Now, subtract 2n from both sides to isolate the n term:
2n - 2n + 4 = 2n - 2n + 1
4 = 1
Since 4 is not equal to 1, there is no solution to this equation.
Therefore, the original equation 2(n + 2) = 4n + 1 - 2n has no solution for n.

Answer:
x=1
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
7x−(6x−1)=2
7x+−1(6x−1)=2(Distribute the Negative Sign)
7x+−1(6x)+(−1)(−1)=2
7x+−6x+1=2
(7x+−6x)+(1)=2(Combine Like Terms)
x+1=2
x+1=2
Step 2: Subtract 1 from both sides.

Simplifying the top:
(2* a^3 * b^5)^2 * (6ab)
4* a^6 *b^10 * (6ab)
24 *a^7 * b^11
so we have
(24 *a^7 * b^11) / (-3* a^5 *b)
immediately we can simplify 24 and -3
(-8 *a^7 * b^11) / ( a^5 *b)
a^7 and a^5 can cancel into just a^2
(-8 *a^2 * b^11) / (b)
b^11 and b cancels to b^10
-8 *a^2 * b^10
so that is your answer:

what is the answer to 7x-35=30+6x
Answer:
x=65
Step-by-step explanation:
you have to get all variables to one side so you would subtract 6 from seven getting one and then add 35 to 30 giving you 65 :)
Answer:
x = 65
Step-by-step explanation:
7x - 35 = 30 + 6x First subtract 6x from both sides
x - 35 = 30 Then add 35 to both sides
x = 65
During a trip Sara knits a scarf at the rate of 469 millimetre everyday if her trip lasts 8 days how much of the scar will she have knitted by the end of the trip
Answer:
3752mm or 3752 millimeter
