The usage of passive income instead of collecting and saving your money without risking a loss through investments:
Passive income is money that you make without having to perform a lot of "active" work to keep it. In essence, you may complete the most of the work upfront and put in some extra effort along the secondary source of income.
Passive income reduces your stress, anxiety, and fear of the future unless there are extremely high-risk investments.It allows you to pursue doing the things you love rather than what pays the bills.Passive income gives you the ability to live and work from anywhere.Help me! Please.✅✅✅✅✅✅

Step-by-step explanation:
I don't know if this is what your looking for but the 38 cars that are 10 years old are 45.78 in percentage and the 5 cars that are more than 20 years are 6.02 in percentage.
(if you are asking how much more percentage to get from 6.02 to 45.78 its 39.76)
I really did not get the question but hope it help a bit.
Answer:
(A) 46% (B) 13%
Step-by-step explanation:
First we can find the percentage of cars that are at least 10 years old by dividing the amount that are 10+ years old by the total amount of cars
[tex]38/83= 0.45783[/tex]
when made into a percentage that is 46%
Now we can find the percentage of those cars that are 20+ years old by dividing the number of 20+ year old cars by our percentage
[tex]5/38=0.13157[/tex]
When made into a percentage That is 13%
Hope this helps! :)

Thomas has to bring home $10.00 change but he wants to buy 2 hamburgers for his sisters will he have enough money to purchase the burgers ?
(2 hamburgers is 2.25)
8
Step-by-step explanation:
you would do 10 divide by 2.25 and that's 4.4 but you can't by half a hamburger so you round down to 4 and then you times 4x2 because it's 2.25 for two hamburgers so your answer is 8.
due tonight help me out please
The average rate of change is the slope.
The slope is equal [tex]\frac{y2-y1}{x2-x1}[/tex], if we were to do that for each set of points, we get the slope is always 8.
Thus the average rate of change is 8.

Answer:
y = - (x - 2)² + 10
Step-by-step explanation:
the equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k ) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square
y = - x² + 4x + 6 ( factor out - 1 from the first 2 terms )
y = - (x² - 4x) + 6
To complete the square
add/subtract ( half the coefficient of the x- term )² to x² - 4x
y = - (x² + 2(- 2) + 4 - 4) + 6
y = - (x - 2)² + 4 + 6
y = - (x - 2)² + 10 ← in vertex form

Ocho veces un número es restado de dos veces su
recíproco. El resultado es 15. Halla el número.
Resolviendo una ecuación cuadratica, veremos que el número puede ser -2 o 1/8.
¿Como transformar una oración en una ecuación?
Partimos de la oración matematica:
"Ocho veces un número es restado de dos veces su recíproco. El resultado es 15. Halla el número."
Primero vamos a definir al número como x.
El reciproco de x es la inversa, es decir, 1/x.
Entonces, a 2 veces ek reciproco de x, le restamos 8 veces x, y eso va a ser igual que 15.
2/x - 8*x = 15
Ahora podemos resolver esto para x, primero multiplicamos a ambos lados por x:
2 - 8x^2 = 15x
-8x^2 - 15x + 2 = 0
Esto es una ecuación cuadratica, las soluciones van a ser:
[tex]x = \frac{-(-15)\pm \sqrt{(-15)^2 - 4*(-8)*2} }{2*(-8)} \\\\x = \frac{15\pm 17}{-16}[/tex]
Entonces tenemos dos soluciones:
x = (15 + 17)/-16 = -2
x = (15 - 17)/(-16) = 1/8
El número puede ser -2 o 1/8.

I need to increase the numbers of customers I talk to daily by 20%. I talk to an average of 8 customers per hour during an 8 hour shift so now I’ll need to talk to ____ customers per day”
Answer:77
Step-by-step explanation:Talk to 8 customers per hour, work 8 hours, so:Talk to 8*8 = 64 customers.
Has to increase by 20%, so 64 is multiplied by 1 + 0.2 = 1.2. Then64*1.2 = 76.8Rounding up, 77 is the answer.

Melissa walks 3 miles to the house of a friend and returns home on a bike. She averages 4 miles per hour faster when cycling than when walking. The total time for the round trip is 2 hours. Find her speed walking and biking. Set up an equation and solve
SHOW WORK PLS!!
Answer: Melissa's walking speed is 2mph. Her biking speed is 6mph
Step-by-step explanation:
Her total distance is 6 miles, because she walks 3 miles, and so the returning distance must also be 3.
Let her cycling speed (in mph) be x
Let her walking speed (in mph) be y
We know that x = y + 4
Since we know that S = D/T:
T = D/S
So her cycling time must be: T = 3/x
and her walking time must be: T = 3/y
since we know that x = y + 4, we can substitute this into her cycling time, and rewrite it as T = 3/y+4
we also know that 3/y+4 + 3/y = 2, because the problem says that the total time taken was 2 hours.
We simply need to solve this equation now:
3/y+4 + 3/y = 2
The LCD for y+4 and y is y² + 4y
so now we have:
(3y/y² + 4y) + (3y+12/y² + 4y) = 2
(6y + 12)/y² + 4y = 2
6y + 12 = 2y² + 8y
2y² + 2y - 12 = 0
Solve this using factoring:
2y² + 2y - 12 = 0
2(y² + y - 6) = 0
(y+3)(y-2) = 0
using ab = 0, then a or b =0:
y = -3, or y = 2
Since speed cannot be negative, our answer is 2 for y. So y, or the walking speed is 2mph. Since x = y + 4, we know that x = 6 mph
Melissa's walking speed is 2mph. Her biking speed is 6mph

domain and range of a linear function that models a real world situation
Answer:
1. the set of all real numbers from 0 to 80.
2. {80, 81, 82, 83, ..., 360}
Step-by-step explanation:
So we know based on the number of days the crew works, a certain amount of road will be completed. The amount of road is dependent on the number of days the crew works.
So, number of days crew works = independent variable = D
amount of road completed = dependent variable = L
Since the crew can work for at most 80 days, they can work from 0 to 80 days.
The first answer is the set of all real numbers from 0 to 80.
The length of roads is the function L = 2D + 200. You plug in the D variable as it asks for it. D's domain is from (0, 80).
So,
L = 2(0) + 200 = 200
L = 2(80) + 200 = 360
The answer is {80, 81, 82, 83, ..., 360}
