9. A water pail in your backyard has a small hole in it. You notice that it has drained a total of 3.5 liters in 4 days. What is the average change in water volume each day?

10. The price of one share of ABC Company declined a total of $45.75 in 5 days. What was the average change in the price of one share per day?

11. To avoid a storm, a passenger-jet pilot descended 0.44 miles in 0.8 minutes. What was the plane’s average change of altitude per minute?

Answers

Answer 1

Answer: 9-11 below

Step-by-step explanation:

9. Well, we're given that the hole drains color(red)(3.5color(white)(l)"L" in color(green)(4color(white)(l)"d", so we can write the rate as

(color(red)(3.5color(white)(l)"L"))/(color(green)(4color(white)(l)"d"))

Now we perform this division, and afterward the denominator will be 1 and thus it will tell us the number of liters drained per day:

(color(red)(3.5color(white)(l)"L"))/(color(green)(4color(white)(l)"d")) = color(blue)(ulbar(|stackrel(" ")(" "(0.875color(white)(l)"L")/(1color(white)(l)"d")" ")|)

Therefore, color(blue)(0.875color(white)(l)"liters" are drained every day on average.

10. $

9.25

decrease per day

Explanation:

We can divide the total price decrease by the number of days it took to reach that decrease to find the average decrease per day:

$

45.75

5

=

$

9.25

decrease per day

11. The average change of altitude per minute would simply be the ratio of distance descended over time. That is:

average change of altitude = distance / time

average change of altitude = 0.44 mile / 0.8 minutes

average change of altitude = 0.55 mile / minute

What is y – 3 = 7 (x – 5) in standard form?

Answers

Answer:

38=7x-y

Step-by-step explanation:

standard form= Ax+By+C

(y-3=7(x-5))

(y-3=7x-35)+3 to both sides

(y=7x-38) +38 to both sides

(y+38=7x) -y to both sides

38=7x-y

you have to move the 38 and y because if you moved the x value, than A becomes negative and it can't be in standard form

Los talleres gráficos "La imprenta" están modificando los salarios de sus empleados. La administración está considerando dos planes, ambos con base en un salario fijo más una comisión en porcentaje por venta al menudeo. El plan A es de $300 de salario más 6% de ventas, y el plan B es de $150 de salario más 10% de ventas. ¿Para qué nivel de ventas serán iguales los planes? Traza en tu libreta la gráfica. LA RESPUESTA SOLAMENTE SE CONSIDERARA COMO CORRECTA SI SE REDACTA COMO LA ESTRUCTURA DEL SIGUIENTE EJEMPLO: $5600.

Answers

Responder:

$ 3750

Explicación paso a paso:

Dado que :

Los planes A y B se basan en un salario fijo más el porcentaje de comisión por venta minorista.

Plan A:

Salario fijo = $ 300

Comisión porcentual = 6% de la venta

Plan B:

Salario fijo = $ 150

Comisión de porcentaje = 10% de la venta

Nivel de venta en el que el plan será el mismo:

Sea nivel de venta = x

Ganancia total por plan:

Plan A:

300 + 0.06x - - - (1)

Plan B:

150 + 0,1x - - - (2)

Igualar (1) y (2)

300 + 0.06x = 150 + 0.1x

0.06x - 0.1x = 150 - 300

-0.04x = - 150

x = 150 / 0,04

x = 3750

Por lo tanto, el nivel de venta en el que ambos planes serán iguales es una venta minorista por valor de $ 3750

Willis analyzed the following table to determine if the function it represents is linear or non-linear. First he found the differences in the y-values as 7 – 1 = 6, 17 – 7 = 10, and 31 – 17 = 14. Then he concluded that since the differences of 6, 10, and 14 are increasing by 4 each time, the function has a constant rate of change and is linear.

Choose the equation that represents the line that passes through the point (6, −3) and has a slope of one half

Answers

Answer:

y = 1/2x - 6

Step-by-step explanation:

slope = 1/2 = m

lets find your y-intercept using slope intercept form: y = mx + b using the points they gave us (6, -3)

y = mx + b; plug what we know to find b, which is our y-intercept.

-3 = 1/2(6) + b

-3 = 3 + b

-6 = b

Now you have all you need to write your equation

y = mx + b

y = 1/2x - 6

Dwight is making accessories for the soccer team. He uses 648.62 inches of fabric on headbands for 39 players and 2 coaches. He also uses 331.89 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player?

Answers

Answer:

24.33 inches

Step-by-step explanation:

inches of fabric on headbands = 648.62 inches

39 players and 2 couches = 41 people

Inches of fabrics per person = Total headbands inches / number of people

= 648.62 inches / 41

= 15.82 inches per person

Inches of fabrics used for headbands per person = 15.82 inches

inches of fabric on wristbands = 331.89 inches

Used for players alone

Inches of fabrics for wristband pee person = Total inches of fabrics for wristband / number of people

= 331.89 inches / 39 players

= 8.51 inches

Inches of fabrics used for wristband per person = 15.82 inches

How much fabric was used on a headband and wristband for each player?

= Inches of fabrics used for headbands per person + Inches of fabrics used for wristband per person

= 15.82 inches + 8.51 inches

= 24.33 inches

Inches of fabrics used on headband and wristband for each player is 24.33 inches

as we can see in the first fraction, they are multiplying the denominator by 5 to get from a denom of 20 to 100. THerefore,  we can now multiply the num of 17/20 by 5 to get our answer. 17x5=85

85/100 can be written as .85.

THe answer is 85

2.

By folowing the same proccess we see that the denom in being multiplied by 2 and therefore by doing the ssame with the num we get 62. 62/100 is 0.62. To find this you can divide 62 by 100 or just know that any number over 100 is the decimel. For example in the fraction 76/100 0.76 is the decimal.

y=88 and x=23 because 4x=3x+23 and y+4x=180

Answer:

x = 23

y = 88

Step-by-step explanation:

because they are parallel lines 3x + 23 = 4x

So you subtract 3x from both sides to get 23 = x

now because you have this and y + 4x = 180

4(23) = 92

180 - 92 = 88

y = 88

Let a and b be real numbers where a ≠ b ≠ 0. Which of the following functions could represent the graph below?

Answers

Answer:

b.

Step-by-step explanation:

The correct function of the graph is,

⇒( f(x) = (x-a)²(x-b)⁴

What is mean by Function?

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Now, Clearly from the graph of the function we could see that zero is not a root of the polynomial function

Hence, option (a) and (c) are discarded.

Now, we will check for option (b) and option (d)

As the graph touches the x-axis at two point i.e. a and b that means that both the roots of the polynomial equation are of even degree.

Hence, the correct option is:

⇒ f(x) = (x-a)²(x-b)⁴
