Step-by-step explanation:

a. 1/4 as a power of 2 = root 4 v/2

b.

Radium-226 mass decays to 1/4 of it mass every 6400 years

64gr ( 1/4) = 16gr ----→after 6400 years its mass is 16gr

now its current mass is 16gr

16gr (1/4) = 4gr -----> after another 6400 years its mass is 4gr

again, its current mass after 12800 years is 4gr

4gr (1/4) = 1gr ------> after another 6400 years its mass is 1gr

why 4600 3 times? = 4600+4600+4600 = 19200 years

the remaining mass after 19200 years is 1gr

Answer:

80 cm²

Step-by-step explanation:

Given 2 similar figures with sides in the ratio a : b , then

ratio of areas = a² : b²

Here ratio of sides = 7 : 14 = 1 : 2

ratio of areas = 1² : 2² = 1 : 4

Thus area of B is 4 times area of A

area of B = 4 × 20 = 80 cm²

Answer: (0,0) on a coordinate plane

Step-by-step explanation:

The word origin has many definitions, but I see that you put this topic question under mathematics, So you are talking about an origin on a coordinate plane.

Origin means start or beginning, on a coordinate plane (Consisting of two lines, one vertical, the y-axis and one being horizontal, which is the x-axis), you would find the Origin in the middle of the place that the x-axis and the y-axis intersect

In the area where those axis's intersect is known as the origin and is also known as the points (0,0)

The perimeter of triangle is 66.24 units.

What is triangle?

In Euclidean geometry, any 3 points, once non-collinear, verify a unique triangle and at the same time, a unique plane

Main body:

according to question :

c = 28

let the vertices be A,B,C

∠A= 30°

by using trigonometric ratios,

BC/ AB = sin30°

AB = C = 28

BC/28 = sin30°

BC = 28*sin30°

BC= 28*(1/2)

BC = 14

similarly

AB /CA = cos 30°

28/CA = √3/2

CA = 28*√3/2

CA = 14/√3

CA = 24.24

Hence , perimeter = AB +BC +CA = 28+14+24.24

                              =66.24 units

The production rate of the assembly line is 6000 parts per month.The assembly line produces 6000 parts per month, with a weekly production rate of 1500 parts.

To calculate the production rate of the assembly line, we need to consider the number of weeks in a month. Since the plant operates for 4 weeks per month, we can divide the total production by the number of weeks to find the weekly production rate.

Given that the assembly operations are sequential, we can calculate the weekly production rate as follows:

6000 parts/month ÷ 4 weeks/month = 1500 parts/week.

Therefore, the assembly line produces 1500 parts per week.

The assembly line produces 6000 parts per month, with a weekly production rate of 1500 parts. This information can be used for planning and managing production schedules efficiently.

Answer:   Which of the following expressions cannot be factored? Explain.

a. 6 + 3x

b. 7x + 3

c. 15x + 10

d. 30x + 40

Step-by-step explanation:

An algebraic equation which represents this word description "Seven more than the quotient of a number b and 45 is greater than 5" is b > -90.

In Mathematics, a quotient can be defined as a mathematical expression that is simply used to represent the division of a number by another number.

In order to translate this word problem into algebraic equation, we would assign a variable to the unknown number and then translate the word problem into algebraic equation as follows:

Let the variable b represent the unknown number.

Translating the word problem into an algebraic equation, we have the following;

7 + b/45 > 5

By collecting like terms, we have the following:

b/45 > 5 - 7

b/45 > -2

By cross-multiplying, we have the following:

b > -2 × 45

b > -90

a. ln(7x) can be expanded as ln(7) + ln(x). b. ln(x + 3) remains as it is, since it cannot be simplified further. c. ln(x^8) can be expanded as 8ln(x). d. 15,000ln(xy^4) can be expanded as ln(x) + 4ln(y) + ln(15,000).

a. To expand the logarithmic expression ln(7x), we can use the property of the natural logarithm that states ln(ab) = ln(a) + ln(b).

Therefore, ln(7x) can be expanded as ln(7) + ln(x).

b. Similarly, the logarithmic expression ln(x + 3) can be expanded using the property ln(ab) = ln(a) + ln(b).

Hence, ln(x + 3) remains as it is since we cannot simplify it further.

c. Expanding the logarithmic expression ln(x^8) can be done using the property ln(a^b) = b * ln(a).

Thus, ln(x^8) becomes 8 * ln(x).

d. Expanding the logarithmic expression 15,000ln(xy^4) can be done by applying the property ln(ab) = ln(a) + ln(b).

Therefore, 15,000ln(xy^4) can be expanded as 15,000[ln(x) + ln(y^4)].

Answer:

30³÷(−5) = -6y²

Step-by-step explanation:

We need to find the value of the given expression :

30³÷(−5)

It can be written as :

\(\dfrac{30xy^3}{(-5xy)}=\dfrac{30}{-5}\times \dfrac{xy^3}{xy}\\\\=-6\times y^2\\\\=-6y^2\)

So, the value of the given expression is \(-6y^2\).

Answer:

x = 9

m∠1 = m∠2 = 54°

Step-by-step explanation:

Two lines r and s are the parallel lines and a transversal line is intersecting these lines at two distinct points.

a). ∠1 ≅ ∠2 [Corresponding angles]

    Therefore, m∠1 = m∠2

    (63 - x)° = (72 - 2x)°

    2x - x = 72 - 63

    x = 9

b). m∠1 = (63 - x)°

            = 63 - 9

            = 54°

    m∠2 = (72 - 2x)°

             = 72 - 18

             = 54°

The maximum value of Z is 60, and it occurs when x1 = 6 and x2 = 0. To solve the given linear programming problem using the simplex method, we first need to convert it into the standard form.

The standard form requires all inequalities to be in the form of ≤ and all variables to be non-negative.

The original problem is:

Maximize Z = 10x1 + 20x2

subject to:

- x1 + 2x2 ≤ 15

x1 + x2 ≤ 12

5x1 + 3x2 ≤ 45

x1 ≥ 0, x2 ≥ 0

To convert the inequalities into equalities, we introduce slack variables (s1, s2, s3) as follows:

- x1 + 2x2 + s1 = 15

x1 + x2 + s2 = 12

5x1 + 3x2 + s3 = 45

Now we can set up the initial simplex tableau:

      | x1 | x2 | s1 | s2 | s3 | RHS |

-------------------------------------

Row 1  | -1 | -2 |  1 |  0 |  0 |  15 |

Row 2  |  1 |  1 |  0 |  1 |  0 |  12 |

Row 3  |  5 |  3 |  0 |  0 |  1 |  45 |

Row 4  | -10| -20|  0 |  0 |  0 |  0  |

Next, we will perform iterations of the simplex method until we reach an optimal solution. In each iteration, we will select the entering variable (column) and the departing variable (row) using the pivot operation.

After performing the necessary pivot operations, we will obtain the final simplex tableau:

      | x1 | x2 | s1 | s2 | s3 | RHS |

-------------------------------------

Row 1  |  0 |  0 |  1 |  2 | -1 |  3  |

Row 2  |  0 |  0 |  0 | -1 |  1 |  6  |

Row 3  |  1 |  0 |  0 | -1 |  1 |  6  |

Row 4  |  0 |  0 |  0 |  0 |  0 |  0  |

From the final tableau, we can see that the optimal solution is:

x1 = 6

x2 = 0

Z = 10x1 + 20x2 = 10(6) + 20(0) = 60

Therefore, the maximum value of Z is 60, and it occurs when x1 = 6 and x2 = 0.
