If apples cost $3.12 per pound and you have a bag that weighs 3pounds and 8 ounces, how much will you pay for those apples?

Answer:

The Probability that a marble selected at random from the bag will NOT be green is 1/3

Step-by-step explanation:

The probability of selecting a green bag

                                            = Total No.of green bags/ Total number of bags

                                           =8/12

                                          = 2/3

Then the probability not of selecting a green bag  

                                                = 1 - The probability of selecting a green bag

                                                 = 1-(2/3)

                                                = 1/3

The height is 230 feet after 9.125 seconds.

We have the  equation that describes the height of the object as a function of time as:

h(t) = -16t^2 + 145t + 2

We input the values and simplify:

-16t^2 + 145t + 2 = 230

-16t^2 + 145t - 228 = 0

we can use the quadratic formula, to solve this quadratic equation,

t = (-b ± √(b^2 - 4ac)) / 2a

where a = -16, b = 145, and c = -228.

t = (-145 ± √(145^2 - 4(-16)(-228))) / 2(-16)

t = (-145 ± √ (21025)) / (-32)

t = (-145 ± 145) / (-32)

t = 0.625 seconds or t = 9.125 seconds

In conclusion, the height is 230 feet after 9.125 seconds.

Based on the word problem, the answer is not one of the given options (E. NOTA).

In this case, we have 9 letters and we want to select all of them, so n = 9 and r = 9. Therefore:

A = 9!

A = 362,880

B) The hypotenuse of a right triangle can be found using the Pythagorean theorem:

c^2 = a^2 + b^2

In this case, we have a = 9 and b = 12. Therefore:

c^2 = 9^2 + 12^2

c = 15

So, B = 15.

y - 9 = 3(x - 6)

y - 9 = 3x - 18

y = 3x - 9

The y-intercept of this line is -9, so C = -9.

Therefore, A + B + C = 362,880 + 15 - 9 = 362,886.

The rate of change of the amount of laundry with respect to the number of loads is a constant value of -1.6 fluid ounces per load.

Any equation that has terms that are either constants or the product of a constant and a variable of the first degree (exponent 1) is said to be linear. In other words, the equation's greatest degree for any variable is 1. One way to express a linear equation is as follows:

ax + b = 0

If an is not equal to zero, a and b are constants, and x is the variable. This is how a linear equation is typically expressed.

The given function is f(x) = 50 - 1.6x.

Now, the rate of change is the slope of the equation.

Comparing the equation with that of the linear equation y = mx + c we see that the slope is -1.6.

The trigonometric identity has been proven as 1 in the space below

Given the identity:

tan(1/2x) (2cot(x) + tan(1/2x)) = 1

To prove this identity, let's start by expressing cot(x) in terms of tan(x):

cot(x) = 1 / tan(x)

Now, replace cot(x) in the given identity:

tan(1/2x) (2(1/tan(x)) + tan(1/2x)) = 1

Now, let's use the double angle formula for tan(x):

tan(x) = 2 * tan(1/2x) / (1 - tan^2(1/2x))

Replace tan(x) in the equation:

tan(1/2x) (2(1/(2 * tan(1/2x) / (1 - tan^2(1/2x))) + tan(1/2x)) = 1

Simplify the equation:

tan(1/2x) ((1 - tan^2(1/2x)) + tan(1/2x) * tan(1/2x)) = 1

Now, notice that the expression in the parentheses is equal to 1:

(1 - tan^2(1/2x)) + tan^2(1/2x) = 1

So, we can simplify the equation further:

tan(1/2x) * 1 = 1

Considering the graph,

The hanger's equation is as follows:

4x= 24

There are 4 numbers here that represent the value of the hanger.

So, x+x+x+x will be 24.

1. Actual Labor Rate per Hour:

The labor price variance formula is:

Labor Price Variance = (Actual Labor Rate - Standard Labor Rate) x Actual Hours

We are given that the labor price variance for April was unfavorable and equal to $1,157. We also know that the standard labor rate was $20 per hour. Using the formula above and plugging in the known values, we can solve for the actual labor rate:

-1,157 = (Actual Labor Rate - 20) x 1,780

-1,157 = 1,780Actual Labor Rate - 35,600

1,780Actual Labor Rate = 34,443

Actual Labor Rate = 19.35

Therefore, the actual labor rate per hour for April was $19.35.

2. Standard Hours Allowed for the Output Achieved:

The flexible-budget variance formula is:

Flexible-Budget Variance = (Actual Hours - Standard Hours) x Standard Labor Rate

We are given that the flexible-budget variance for April was favorable and equal to $1,643. We also know that the standard labor rate was $20 per hour.

Using the formula above and plugging in the known values, we can solve for the standard hours allowed:

1,643 = (1,780 - Standard Hours) x 20

1,643 = 35,600 - 20Standard Hours

The inequality that represents all possible values for the amount of money that Joann has is 21 ≤ J ≤ 50.

Let's call the amount of money that Joann has in her wallet "J" and the amount of money that Shana has in her wallet "S".

We know that the total amount of money they have is at least $56 and at most $85. Therefore, we can write two inequalities:

J + S ≥ 56 (the total is at least $56)

J + S ≤ 85 (the total is at most $85)

We also know that Shana has only $35 in her wallet. We can substitute this value for S in the inequalities to get an inequality that represents all possible values for the amount of money that Joann has:

J + $35 ≥ 56 (substituting S = $35 in the first inequality)

J + $35 ≤ 85 (substituting S = $35 in the second inequality)

Simplifying these inequalities by subtracting $35 from both sides, we get:

J ≥ 21 (the amount of money Joann has is at least $21)

J ≤ 50 (the amount of money Joann has is at most $50).

The dimensions of the strongest beam are 27 inches x 13.5 inches.

In general, dimension refers to a measurable extent of a physical quantity, such as length, width, height, depth, or time. These dimensions provide a framework for describing and measuring objects and events in the physical world. In geometry, dimension are refers to the number of coordinates needed to specify a point in a space. In physics, the concept of dimension is used to describe the properties of space and time.

We know that the strength of the beam is directly proportional to its width multiplied with the square of its height. Let's call the width of the beam "w" and the height "h". Then we can write the strength of the beam as:

S = kwh², where "k" is the constant of proportionality.

We want to find the dimensions of the strongest beam, which means we want to find the values of "w" and "h" that will maximize the strength "S". To do this, we need to find the maximum value of the function S = kwh² subject to the constraint that the diameter of the log is 18 inches.

The diameter of the log is equal to the width of the beam plus twice the height of the beam:

d = w + 2h

Since the diameter of the log is 18 inches, we can write:

w + 2h = 18

or

w = 18 - 2h

Substituting this expression for "w" into the equation for the strength of the beam, we get:

S = k × w(18-2h) × h²

Expanding and simplifying this expression, we get:

S = 36kh³ - 2kh⁴

To find the maximum value of S, we take the derivative of S with respect to h and set it equal to zero:

dS/dh = 108kh² - 8kh³ = 0

Simplifying this expression, we get:

h²(108 - 8h) = 0

This equation has two solutions: h = 0 and h = 13.5.

Since a beam with height equal to zero would have zero strength, we reject the solution h = 0. Therefore, the maximum strength is achieved when h = 13.5 inches.

To find the corresponding width, we can use the equation we derived earlier:

w = 18 - 2h = 18 - 27 = -9

Since the width of the beam cannot be negative, we reject this solution as well.

Therefore, the required dimensions of the strongest beam are:

Width = 2h = 2(13.5) = 27 inches

Height = h = 13.5 inches

Answer:

We can use trigonometry to find AB.

First, we can use the fact that the sum of the angles in a triangle is 180° to find angle A:

A + B + C = 180°

A + 90° + 30° = 180°

A = 60°

Now, we can use the sine function to find AB:

sin A = opposite/hypotenuse

sin 60° = AB/96

AB = 96 * sin 60°

AB = 96 * √3/2

AB = 48√3

Therefore, AB is approximately 83.14 cm (rounded to two decimal places).
