Answers

Answer 1

Answer:

Its probably too late now but the answer is 83

Step-by-step explanation:

Answer 2

83 is the lowest grade she can make on her last test to finish with an 80 test average.

What is Probability?

It is a branch of mathematics that deals with the occurrence of a random event.

Given that Jamie wants to make an 80, or B, test average in her class.

She scored 75 and 82 on her last 2 tests.

we need to find the  lowest grade she can make on her last test to finish with an 80 test average

Let x be the e  lowest grade she can make on her last test to finish with an 80 test average

75+82+x/3=80

157+x=240

Subtract 157 from both sides

x=83

Hence, 83 is the  lowest grade she can make on her last test to finish with an 80 test average.

A graph shows time (weeks) labeled 2 to 8 on the horizontal axis and height (inches) on the vertical axis. A line of orange dots increases from 0 to 9 weeks starting at 2 on the vertical axis. The graph shows the recorded heights of a plant in a soil experiment. Which statements describe the plant height function? Check all that apply. The function is linear. The function is quadratic. The height increases at a constant rate of change. The ratio of height and number of weeks is constant. There is no relationship between height and number of weeks.

Answers

Answer:

A.) The function is linear.

C.) The height increases at a constant rate of change.E

Step-by-step explanation:

Edge 2022

The function is linear and the height increases at a constant rate of change are the correct statements of the given graph.

What is Graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Based on the description, it seems that the function is linear because the graph shows a line of dots that increases at a constant rate from 0 to 9 weeks.

Therefore, the following statements apply:

The function is linear.

The height increases at a constant rate of change.

Linear functions are those functions whose graph goes in a straight line. This function has one independent variable and one dependent variable.

The height increases at a constant rate of change. We can see as the time is increasing the height is increasing. We can determine this by slope of graph.

Hence, the function is linear and the height increases at a constant rate of change are the correct statements of the given graph.

The rectangular prisim below has a total surface area of 158 in use the net to determine the missing dimension

Answers

Answer:

The problem seems to be incomplete, after an online search I couldn't find the complete question, to be able to solve the question, I will assume that the known measure is the width W.

For a rectangular prism of length L and width W, the surface area is calculated as:

S = W*L

For the assumption we took, we have:

W = 39.5ft

And we also know that S = 158 ft^2

And we want to find the missing dimension, in this case is L, then we need to solve:

158 ft^2 = W*L

We just need to divide both sides by the known measure, W

We get:

(158 ft^2)/W = L

So you just need to replace the known value, and can find the missing one.

You have tiles numbered 1-9 in a bag. What is the probability of drawing a multiple of 3,putting it aside, and then drawing the number 5

Answers

Answer:

1/18

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

Multiples of 3 between 1 - 9 = 3,6,9

Probability of picking a multiple of 9 = total multiples of 9 in the bag / total tiles in the bag

3/9

To transform to the simplest form. divide both the numerator and the denominator by 3

1/3

After picking the multiples of 3, the tiles are not replaced, tiles in the bag would now be 6

Probability of picking 5 = 1/6

1/6 x 1/3 = 1/18

Answer:

The roots of a function are the x-intercepts. By definition, the y-coordinate of points lying on the x-axis is zero. Therefore, to find the roots of a quadratic function, we set f (x) = 0, and solve the equation, ax2 + bx + c = 0.

enta al 4% de interés anual y otra al 5% anual. Calcula ambas partes


que el capital acumulado al cabo de un año es de $9,400.00 dólares.

Answers

Answer:

La respuesta al ejercicio es:

$4,000.00 al 5% anual.$5,000.00 al 4% anual.

Step-by-step explanation:

Teniendo en cuenta que el capital inicial es de $9,000.00 y el capital tras un año es de $9,400.00, se identifica en primera instancia que la ganancia gracias al interés anual fue de $400, por lo cual se pueden tener en cuenta las siguientes variables:

x = monto de dinero al 5% anual.y = monto de dinero al 4% anual.

Y el siguiente sistema de ecuaciones:

x + y = 9000x * 5% + y * 4% = 400

En la segunda ecuación, cambiaremos los porcentajes para facilitar los cálculos posteriores:

   2. x * 0.05 + y * 0.04 = 400

Lo cual también se puede representar como:

   2. 0.05x + 0.04y = 400

Procedemos a despejar una variable, en este caso despejaré la variable y de la primera ecuación:

x + y = 9000y = 9000 - x

Y la reemplazaré en la segunda ecuación:

0.05x + 0.04y = 4000.05x + 0.04 (9000 - x) = 400

Ahora operamos:

0.05x + 360 - 0.04x = 400

Restamos las variables x:

0.01x + 360 = 400

Y despejamos el valor real de x:

0.01x = 400 - 360x = 40 / 0.01x = 4000

Ya que x es el monto de dinero puesto al 5% anual, ahora sabemos que dicho monto fue $4,000.00, por último, reemplazamos este valor en la primera ecuación para identificar el valor de y:

x + y = 90004000 + y = 9000y = 9000 - 4000y = 5000

Por último, sabemos que el monto de dinero puesto al 4% fue $5,000.00.

Ferdinand is playing golf. He hits a shot off the tee box that
has a height modeled by the function h(t) = –16t2 + 80t,
where h(t) is the height of the ball, in feet, and t is the time
in seconds it has been in the air. The graph that models
the golf ball's height over time is shown below.

When does the ball reach its maximum height?

What is the maximum height of the ball?

Answers

Answer:

Maximum height of the ball = 100 m

Time to reach the maximum height = 2.5 seconds

Step-by-step explanation:

Function that models the height h(t) of the ball and time 't',

h(t) = -16t² + 80t

Convert this equation into vertex form,

h(t) = -16(t²- 5t)

     = -16[t² - 2(2.5t) + (2.5)² - (2.5)²]

     = -16[[t² - 2(2.5t) + (2.5)²] + 16(2.5)²

     = -16(t - 2.5)² + 16(6.25)

     = -16(t - 2.5)² + 100

By comparing this equation with,

g(t) = a(x - h)² + k

Here, (h, k) is the vertex of the parabola.

Vertex of the given parabola will be → (2.5, 100)

Therefore, maximum height of the ball = 100 m

Time taken by the ball to reach the maximum height = 2.5 seconds
