What is the first step to converting from a fraction to a decimal ?
Answer:
To convert a fraction into a decimal, divide the top number by the bottom number. What about with denominators that don't divide into 10, 100 or 1000, such as 7? You still divide the denominator into the numerator, no matter what the numbers are.

1999 total revenue of a company from music sales and Licensing was 14.2 billion dollars. It was forecasted that this number would continue to drop until it reaches 5.3 million in 2014. Find the percent decrease in music revenue.
Answer:
62.67%
Step-by-step explanation:
Total revenue of a company from music sales is 14.2 billion dollars in 1999.
It reaches 5.3 million in 2014.
We need to find the percent decrease in music revenue. It can be given by :
[tex]\%=\dfrac{|\text{original value-decrement value}|}{\text{original value}}\times 100\\\\\%=\dfrac{|14.2-5.3|}{14.2}\times 100\\\\\%=62.67[/tex]
So, the percent decrease in music revenue is 62.67%.
Podemos calcular la profundidad d
de la nieve, en centímetros, que se acumula en el jardín de Harper durante las primeras h horas de una tormenta usando la ecuación
d=5h
Cuántas horas tarda en acumularse 1
centímetro de nieve en el jardín de Harper?
Cuántos centímetros de nieve se acumulan por hora?
Answer:
a) Cuántas horas tarda en acumularse 1
centímetro de nieve en el jardín de Harper?
0.508 horas o 30.48 minutos
b) Cuántos centímetros de nieve se acumulan por hora?
5 cm
Step-by-step explanation:
a) ¿Cuántas horas se necesitan para acumular 1 pulgada de nieve en el jardín de Harper?
1 pulgada de nieve = 2.54 cm de nieve
d = 5 × h
2.54 = 5 h
h = 2.54 / 5
h = 0.508 hora
Convertir a minutos = 0.508 horas × 60 minutos
= 30.48 minutos.
Por lo tanto, se necesitarían 0.508 horas o 30.48 minutos para acumular 1 pulgada de nieve en el jardín de Harper.
b) ¿Cuántos centímetros de nieve se acumulan por hora?
d = 5 h
Por hora = 1 hora
d = 5 × 1
d = 5 cm
Por tanto, se acumulan 5 cm de nieve por hora.
A candy store uses 77.2 grams of sugar each hour. How many grams of sugar will the store use in 10 hours?
Answer:
The store will use 772 grams of sugar in 10 hours.
Taking into account the rule of three, a candy store uses 772 grams of sugar in 10 hours.
Rule of threeThe rule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.
That is, what is intended with it is to find the fourth term of a proportion knowing the other three.
If the relationship between the magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other), the direct rule of three must be applied.
To solve a direct rule of three, the following formula must be followed, being a, b and c known data and x the variable to be calculated:
a ⇒ b
c ⇒ x
So: [tex]x=\frac{cxb}{a}[/tex]
Grams of sugarThe rule of three can be applied as follow: if in 1 hour a candy store uses 77.2 grams of sugar, in 10 hour how many mass is used?
1 hour ⇒ 77.2 grams
10 hours ⇒ x
So: [tex]x=\frac{10 hoursx77.2 grams}{1 hour}[/tex]
Solving:
x= 772 grams
In summary, a candy store uses 772 grams of sugar in 10 hours.

Simplify 3{[3(9 – 2)] + [7(8 – 1)]}
Answer:
210
Step-by-step explanation:
Use the order of operations pemdas( parenthesis, exponent, multiply, divide, add, subtract)
first do everything within the parenthesis.
3 ( ( 3 (9-2) ) + ( 7 (8-1) ) )
3 ( ( 3 (7) + ( 7 ( 7 ) ) )
3 ( ( (21) + (49) ) ) )
3 ( ( 21 + 49 ) )
3 ( 70 )
3 (70) = 70 + 70 + 70 = 140 + 70 = 210

Use the residual plot to determine if this linear model is appropriate.
Answer:
The linear model is not appropriate.
Step-by-step explanation:
In regression, the difference amid the observed-value of the dependent-variable (y) and the predicted-value ([tex]\hat y[/tex]) is known as the residual (e).
[tex]e=y-\hat y[/tex]
A residual plot is a graphical representation of the residuals on the y-axis and the independent variable on the x-axis. If the data-points on the residual plot are randomly spread around the x-axis, a linear regression model is appropriate for the data. And if the residual plots shows a non-random or a U or inverted U pattern, a nonlinear model is more appropriate for the data.
The residual provided shown an inverted U pattern. That is the points are not scattered around he graph.
Thus, the linear model is not appropriate.
A residual plot for the nutrition data would display the residuals on the y-axis and the age on the x-axis.
The residual plot is not appropriate for a linear model.
From the residual plot (see attachment), we can see that the points on the residual plot follows a curved pattern.
For a residual plot to be a linear model, the points on the plot must be at random on the horizontal axis of the plot.
This means that, the residual plot is not appropriate for a linear model.

One car dealer sells a car with a $500 down payment and payments of $250 per month. Another car dealer sells the same type of car with no down payment and monthly payments of $300 per month. After how many months will the buyers have paid the same amount? Use m for your variable
Answer:
By month 10 both buyers will have paid the same amount of 3,000.
Step-by-step explanation:
The equation would be 500 + 250m = 300m. If you put 10 in for m you get the same amount on both sides of the equation.
500 + 250m = 300m
500 + 250(10) = 300(10)
500 + 2,500 = 300(10)
3,000 = 300(10)
3,000 = 3,000

Chau rented a truck for one day. There was a base fee of $20.99, and there was an additional charge of 79 cents for each mile driven. Chau had to pay $130.80 when he returned the truck.
For how many miles did he drive the truck?
Answer:
Chau drove 139 miles
Step-by-step explanation:
Knowing how much Chau spent at the end makes the question much much easier. So what you want to do is take of the base fee ($20.99) off the final amount he had to pay.
$130.80 - $20.99 = $109.81
Now you divide $109.81 by the additional charge ($0.79)
Change the divisor (0.79) to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend (109.81) the same, 2 places to the right.
We then have the equations:
10981 ÷ 79 = 139.000
and therefore:
109.81 ÷ 0.79 = 139.000
Chau drove 139 miles.

-3/4
Step-by-step explanation:

0-3/5-1
A line contains points M(1, 3) and N(5, 0). The slope of MN is -3/4.
What is the slope of the line?A line's slope provides information on the steepness and direction of the line. By calculating the difference between the coordinates of the two locations, (x1,y1) and (x2,y2), it is simple to calculate the slope of a straight line between them.
The slope, m, of the line, is calculated through the equation,
The formula used to find the slope is,
m = (y2 - y1)/ (x2 - x1)
Where (x1, y1) and (x2, y2) are the points
The given points on the line are:
M(1, 3) and N(5, 0)
Substituting it in the formula,
m = (0 - 3)/ (5 - 1)
m = -3/4
Therefore, the slope of MN is -3/4.
