An element with a mass of 400 grams decays by 29.8% per minute. To the nearest
minute, how long will it be until there are 2 grams of the element remaining?
The time elapsed, to the nearest minute, until only 2 grams of the element remains is 15 minutes.
We have an element. The element has a mass of 400 grams. The element decays by 29.8% per minute. We need to find the time duration after which there will be only 2 grams of the element remaining. Let the initial mass of the element, the final mass of the element, the rate of decay, and the time elapsed be represented by the variables m, M, r, and t. We can write the equation as given below.
M = m(1 - r)^t
2 = 400(1 - 0.298)^t
0.005 = (0.702)^t
log(0.005) = t*log(0.702)
t = log(0.005)/log(0.702)
t = 14.97
The time taken, to the nearest minute, is 15 minutes.

What is the system of linear equations in three variables?
Three-variable equation systems are only slightly more difficult to solve than two-variable equation systems. Substitution and the use of 3x3 matrices are the two most straightforward methods for solving these types of equations.
The given equations are
r - 3s + t = 4 ------------(I)
3r - 6s +9t = 5 ---------(II)
4r - 9s + 10t = 9--------(III)
from equation (I), we get
r = 4 + 3s - t ------------(IV)
Now put the value of 'r' in equations (II) and (III), and we get
3(4 + 3s - t) - 6s + 9t = 5
4(4 + 3s - t) - 9s + 10t = 9
Solving the above equations, we get
3s + 6t + 12 = 5 --------(V)
3s + 6t + 16 = 9 --------(VI)
Now isolate the value of 's' from equation (IV), we get
3s = - 6t + 5 -12
[tex]s=\frac{-6t-7}{3}[/tex]
Now put the value of 's' in equation (IV), and we get
[tex]r=4 +3s -t\\r=4+3\cdot(\frac{-6t-7}{3}) -t\\ r=4-6t-7-t\\r=-7t-3[/tex]

Lulu the Lucky puts chests of gems into her treasure vault. Each chest holds the same number of gems. The table below shows the number of gems Lulu received from three different adventures and the number of chests she needed to hold the gems
An equation to describe the relationship between g, the number of gems, and c, the number of chests is; g = 300c
How to solve Linear Equation Word Problems?
In adventure A, when number of gems is 600, we see that number of chests is 2. Thus;
Rate of gems per chests = 600/2 = 300 g/c
In adventure B, when number of gems is 1500, we see that number of chests is 5. Thus;
Rate of gems per chests = 1500/5 = 300 g/c
In adventure C, when number of gems is 4800, we see that number of chests is 16. Thus;
Rate of gems per chests = 4800/16 = 300 g/c

(b) Graph this system to show both solutions. Label each axis appropriately.
a) The revenues for both items will be the same after 1 day.
b) The graph with the solution is given by the image at the end of the answer.
How to obtain the number of days for which the revenues will be the same?The functions defining the revenues for the selling of x brownies and of x cookies are presented as follows:
Brownies: B(x) = 2x² + 8x - 4.Cookies: C(x) = 2x + 4.The revenues will be the same after x days, for which:
B(x) = C(x).
Hence:
2x² + 8x - 4 = 2x + 4
2x² + 6x - 8 = 0.
x² + 3x - 4 = 0.
The quadratic function can be factored as follows:
(x + 4)(x - 1) = 0.
Applying the Factor Theorem, the solutions are given as follows:
x + 4 = 0 -> x = -4, which is an extraneous solution, as the number of days cannot be negative.x - 1 = 0 -> x = 1, which is the number of days when the revenues are the same.The graph shows the intersection of the two curves, B(x) and C(x).

show that the convergence of a series is not affected by changing a finite number of its terms. (of course, the value of the sum may be changed.)
Convergent Series:
A Convergent Series is a series whose partial sums tend to a specific member is called a limit.
∑ 1/2n = 1/2+ 1/4 + 1/8 + 1/16 +........
Given an infinite series ∑₁ ∞ an determine the series is convergence. Recall that we can actually do better with geometric series not only we can determine convergence but also divergence. We can also calculate geometric series.
Suppose we are given a series ∑ aₙ which is not quite a geometric series but becomes a geometric series for sufficiently large n. That is we can find an integer N such that aₙ = aₓⁿ for all n > N. we don't have a general formula for aₙ when n ≤ N. The values of aₙ for small n don't effect Sₙ is convergence or not.
As a moment of fact, we never used the fact that aₙ eventually become geometric. More general ∑aₙ is convergent series, we can add a finite number of terms to the be gaining of this series or remove a finite number of terms from the be gaining of the series without affecting the convergence of the series. For Example: if ∑aₙ convergence then so does
10 + 10¹⁰ + 10 ¹⁰⁰ + 10¹⁰⁰⁰ + ∑aₙ
Similarly, if ∑aₙ convergence then,
a₁₀₀₀ +a₁₀₀₁ +a₁₀₀₂ + ..... = ∑₁₀₀₀ ∞ aₙ
However, the fact that we are only adding finitely many terms to the series is essential. That is, when it comes to determining convergence of a series ∑aₙ , we can see that only the asymptotic behavior of ∑aₙ matter, that is, only the behavior of the sequence aₙ as n--- ∞ affects convergence.

What is distance?In Science, distance can be defined as the amount of ground that is covered (travelled) by a physical object over a particular period of time and speed, irrespective of its direction, starting point or ending point.
Mathematically, the distance traveled by a physical object (body) can be calculated by using this formula:
Distance = speed (rate) × time
Note: Let the variable x represent the halfway distance.
Since it takes the same amount of time to walk each block and halfway there, half of the berries are gone. Therefore, we have the following:
At point x, the number of strawberries that is left is equal to 12 strawberries while the distance after walking 3 more blocks, you still have 5 blocks to go would be given by:
1/2 × x = (3 + 5) = 8
1/2 × x = 8
Distance, x = 8 × 2
Distance, x = 16 blocks.
Now, we can determine the rate at which this person walks a block:
Rate (speed) = 28/16
Rate (speed) = 1.75 minutes.

The lengths of the major and minor axis are 4√6 and 4√3.
What is Major and Minor Axis?A point on a curve is described by an ellipse if its location is such that the sum of the distances between its two focal points is a constant.
(x−h)²/ b² +(y- k)² /a² = 1
Given:
(x−3)²/ 27+(y+4)² /45=1
The above equation can be compared to the standard equation of an ellipse
(x−h)²/ b² +(y- k)² /a² = 1
where, (h, k) = coordinates of the center of the ellipse
a = length of the semi major axis
b = length of the semi minor axis
By comparison, we have;
(h, k) = (3, -4)
a = √(24) = 2 x√6
b = √(12) = 2 x√3
and, length of the major axis = 2a
length of the minor axis = 2b
Thus, The length of the major axis is
2x a = 2 × 2 x √6 = 4√6

The perimeter of a triangle is 6p + 2q - 5 units. One side length is p - 3 units. The second side length is 2p + 3q units. Which expression represents the length, in units, of the third side of the triangle?
Answer: 3p-q-2
Step-by-step explanation:
Perimeter is the sum of all the sides.
Add the known sides together:
(p-3) + (2p+3q) = 3p + 3q - 3
To find the unknown side, subtract the sum of the 2 known sides from the perimeter (combine like terms):

for the first 11 months of this year , Dan's sales averaged 24,870 a month. What must be Dan's sales for the next month if he wants his monthly average for the year to be 25,000
Dan's sales for the next month if he wants his monthly average for the year to be 25,000 is 36430.
How to calculate the value?Since for the first 11 months of this year , Dan's sales averaged 24,870 a month. The total amount will be:

Write an equation of the line passing through point P(-1, 3) that is perpendicular to y = 4x - 7
The equation of line is y = -1/4x + 11/12.
What is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx
where, m is the slope
Given:
line passing through P(-1, 3) that is perpendicular to y = 4x - 7.
Now, the slope of perpendicular line is
slope= -1/ 4
and, the lines passes through (-1, 3)
Thus, using slope- intercept form
y- 3 = m( x + 1)
y- 3 = -1/4 ( x+ 1)
y- 3 = -1/4x - 1/4
y = -1/4x + 11/12
