2. B.C.E. is the same as... A. Before Christ C. Anno Domini B. After Death D. Before Christmas​

Answer:

$63

Step-by-step explanation:

Penny = $0,01

Nickel = $0.05

Dime = $0.1

Quarter= $0.25

Number of pennies = 6*50 = 300

Number of nickels = 5*40= 200

Number of dimes = 4*50= 200

Number of quarters = 3*40 = 120

The total amount of money:

300*0.01+ 200*0.05 + 200*0.1 + 120*0.25 = $63

Plan B is less expensive than Plan A when you use at least 25

Inequalities can simply be defined as mathematical expressions in which both or two sides of the expression are not equal.

From the information given, we have that;

Now, let's write the inequality that represents Plan B < Plan A

If Plan B < Plan A

Then,

0. 19m + 6. 00 <  0. 25m

Let's simply the inequality

6. 00 < 0. 25m - 0. 19m

0. 06m < 6. 00

Make 'm' the subject

m < 6. 00/ 0. 06

m < 100

Thus, Plan B is less expensive than Plan A when you use at least 25

The probability of randomly drawing the chip number 564 is 1 / 713 or 0.0014

Probability is used to determine the odds that a random event would happen. The odds that the event would happen is a distribution that lies between 0 and 1.

If it is certain that the event would occur, the probability value would be 1. If  it is certain that the event would not occur, the probability value would be 0. If it is equally likely that the event would happen or not happen, the probability value would be 0.5.

The more likely the event is to happen, the closer the probability value would be to 1. The less likely it is for the event not to happen, the closer the probability value would be to zero.

The probability of randomly drawing the chip number 564 = number of chips numbered 564 / total number of chips

The slope of the equation of the line described is equal to 1/3.

A slope is also referred to as gradient and it's typically used to describe both the ratio, direction and steepness of the function of a straight line.

Mathematically, the slope of any straight line can be calculated by using this formula;

[tex]Slope = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

Mathematically, the standard form of the equation of a straight line is given by;

y = mx + c

Where:

y + 2 = 1/3(x-8)

y + 2 = 1/3x - 8/3

y = 1/3x - 8/3 - 2

y = 1/3x - 2/3

Therefore, the slope of the equation of the line described is equal to 1/3.

the cost per book is 3$. you can buy 7 books for 21$.

Step-by-step explanation:

15 divided by 5 is 3, so they cost 3 each. 21 divided by 3 is 7.

The magnitude of an earthquake is related to the relative intensity by

magnitude = log(relative intensity).

Magnitude is a measure of earthquake size and remains unchanged with distance from the earthquake. Intensity, however, describes the degree of shaking caused by an earthquake at a given place and decreases with distance from the earthquake epicentre.

A better measure of the size of an earthquake is the amount of energy released by the earthquake, which is related to the Richter Scale by the following equation:

Log E = 11.8 + 1.5 M

(where Log refers to the logarithm to the base 10, E is the energy released in ergs and M the Richter magnitude).

Magnitude is determined from measurements on seismographs. Intensity measures the strength of shaking produced by the earthquake at a certain location. Intensity is determined from effects on people, human structures, and the natural environment.

An earthquake's magnitude is inversely proportional to its relative intensity (magnitude = log) (relative intensity)

Based on the money earned by Kaleigh's aunt from Wheels Around Town, the relationship between miles and money earned is proportional.

In a proportional relationship, the rate of increase or decrease in x should be equivalent to the rate of increase or decrease in y. This rate should be constant through the entire distribution.

The equation of the line should take the form:
y = mx

There should be no y-intercept.

The slope is:

= (48  - 72) / (120 - 180)

= -24 / - 60

= 2/5

Every value of y has to be 2/5 of x.

= 160 x 2/5 = 64

= 200 x 2/5 = 80

The relationship is therefore proportional.

The maximum value of the objective C = 5x -4y over given constraints is

In any optimization problem, when we need to either maximize or minimize some objective function for that we are given some limitations or logical conditions which the objective function  needs to satisfy in order to maximize or minimize.

These constraints are in the form of equalities or inequalities, where a feasible region satisfying all these equalities or inequalities is first found and then we maximize/minimize our objective on the boundary points of this feasible region.

Given problem is:

Maximize Objective function C = 5x-4y

When system of constraints are (i) x≥0 , (ii) y≥0 , (iii) 4 ≤y+ x

(iv) y ≤ (1/5)x +1

We will graph this system of constraints to find the feasible area.

x≥0,y≥0 represents that feasible area is in the 1st quadrant

For 4 ≤ x + y, we will use corresponding x+ y = 4 equality

When x= 0 then y=4 and when y=0 then x=4 , then y+ x = 4 is a line passing through (0,4) and (4,0)

When be substitute (0,0) in 4 ≤ x + y we get 4 ≤0 which is a false statement .

Therefore,4 ≤y + x is the region starting with line x+ y = 4 and area above this line in opposite direction of origin.

For y ≤ (1/5)x +1, we will use y = (1/5)x +1, put x= 0 we get y=1 and put y=0 then x= -5 , then y= (1/5)x +1 is a line passing through (0,1) and (-5,0)

And on substituting (0,0) in y ≤ (1/3)x +1 we get 0 ≤ 1 which is a true statement .

Therefore, y ≤ (1/5)x +1 is region including the line y = (1/5)x +1 and area on the side of this line that is towards origin

The feasible region is shown in the attached picture with the boundary points of the shaded area.

ABC is the shaded area is feasible area,  where A= (0,4)   ,B= (2.5, 1.5 ), C= (0,1)

Z at A : 5(0) -4 (4) =-16

Z at B : 5(2.5) -4(1.5) =6.5

Z at C : 5(0) -4(1) = -4

Clearly, maximum value of z in feasible area is Z= 6.5 at point (2.5, 1.5)

According to the solving it is proved that DE is parallel to BC.

Coordinates are numerical lengths or angles that uniquely identify points on two-dimensional (2D) or three-dimensional (3D) surfaces ( 3D ). Mathematicians, physicists, and engineers employ a variety of coordinate systems.

In-parallel refers to something that is the same distance as well as the direction away from something else. Two lines of individuals standing straight across from each other is an example of in-parallel. noun. 1. In-parallel means traveling the same direction and distance as something else.

To obtain the coordinates of each midpoint, use the midpoint formula.

(x, y) = (½ (x₁ + x₂), ½(y₁ + y₂))

Coordinates of D:

(x, y) = (½ (4 + 2), ½(6 + -2))

(x, y) = (3, 2)

Coordinates of E:

(x, y) = (½ (4 + -2), ½(6 + -4))

(x, y) = (1, 1)

Slope of DE:

m = Δy / Δx

m = (2 − 1) / (3 − 1)

m = 1/2

Slope of BC:

m = Δy / Δx

m = (-2 − -4) / (2 − -2)

m = 1/2

In an arithmetic progression (AP) sequence of numbers, the difference between any two consecutive integers is always the same. It is also known as an arithmetic sequence.

There are two definitions for an arithmetic sequence. Each term in an arithmetic sequence is created by adding a predetermined number (positive, negative, or zero) to its preceding term. It is a "series where the differences between every two following terms are the same."

Given,

first term, a = 7

common difference d = 7

n = 2

a+(n-1)d = 7+( 2 - 1 )7

= 7 + 7

= 14
