To the nearest minute, it will be 10 minutes until there are 70 grams of the element remaining.

The time the element took to decay can be found by using the following formula:

\(F=P(1-r)^{t}\)

Where:

We can find the answer by substituting the values.

\(F=P(1-r)^{t}\\\Rightarrow 70=840(1-0.229)^{t}\\\Rightarrow \frac{70}{840} =(1-0.229)^{t}\\0.0833=(1-0.229)^{t}\\t=9.56\\\approx10 \text{ minutes}\)

Therefore, we have found that the element will take around 10 minutes to have 70 grams remaining.

So

: (-4-4)--(-2,-4);

: (-4,-8)--(-2,-8);

: (-8,-8)--(-6,-8);

: (-8,-6)--(6-6);

2. Reflect the translator image Figure M across the Z-axis according to the rule.

Answer:

\(x=96\)

Step-by-step explanation:

\(360=x+\left(x+90\right)+\left(x-18\right)\)

Step 1: Simplify both sides of the equation.

\(360=x+x+90+x-18\)

\(360=(x+x+x)+(90+-18)\) (Combine Like Terms)

\(360=3x+72\)

Step 2: Flip the equation.

\(3x+72=360\)

Step 3: Subtract 72 from both sides.

\(3x+72-72=360-72\)

\(3x=288\)

Step 4: Divide both sides by 3.

\(\frac{3x}{3}=\frac{28}{3}\)

\(x=96\)

M= ([-1],[1/2])

The number in the green box is -1

Step-by-step explanation:

M= ([x1+x2/2], [y1+y2/2])

M= ([2+(-4)/2], [5+1/2])

M= ([-2/2, 6/2])

M= ([-1, 3])

Therefore, the rank of matrix 'a' in this case would be 5.

To find the rank of a matrix, we need to perform row reduction to obtain its row echelon form (REF) or reduced row echelon form (RREF). However, since the matrix 'a' is not provided, I cannot perform the calculations or determine its rank.

The rank of a matrix is equal to the number of non-zero rows in its row echelon form or reduced row echelon form. If the system of equations 'ax = 0' has a two-dimensional solution space, it means that the rank of matrix 'a' is less than the number of columns (6) but greater than 4 (since the solution space is two-dimensional).

Step-by-step explanation:

Weight of a 24 square foot, 2 inch thick aluminum plate will be: 720 lbs.

A single unit's value can be determined from the values of multiple units, and multiple units' values can be determined from the values of single units using the unitary method.

Given:

To find: weight of a 24 square foot, 2 inch thick aluminum plate

Finding:

By unitary method, we get:

Weight of 1 square foot aluminum plate = 15 lbs.

Weight of 24 square foot aluminum plate = 15(24) lbs = 360 lbs.

Again, by unitary method, we get:

Weight of 1 square foot, 1 inch thick aluminum plate = 15 lbs.

Weight of 24 square foot, 1 inch thick aluminum plate = 15(24) lbs = 360 lbs.

Weight of 24 square foot, 2 inch thick aluminum plate = 360(2) lbs = 720 lbs.

Hence, Weight of 24 square foot, 2 inch thick aluminum plate = 720 lbs.

The rate of filling water in the tank is 23450t gallons per hour.

Let's assume that the time taken to fill the tank is t hours.

The volume of water filled into the tank at time t is given by the expression V(t) = 23450t.

The tank is originally empty, which means its volume = 0 gallons.

After 5 hours,

t= 5 hours

The volume of water filled in is given by \(V(5) = 23450 * 5= 1,17,250\) gallons of water.

Therefore, 1,17,250 gallons of water are filled in the tank after 5 hours.

The linear distance traveled in one revolution of a wheel can be calculated using the formula:

Circumference = π * Diameter

Given that the diameter of the wheel is 36 inches, we can substitute the value into the formula:

Circumference = π * 36 inches

Using an approximate value of π as 3.14159, we can calculate the circumference:

Circumference ≈ 3.14159 * 36 inches

Circumference ≈ 113.09724 inches

Therefore, the linear distance traveled in one revolution of a 36-inch diameter wheel is approximately 113.09724 inches.

Answer:

0.4987

Step-by-step explanation:

What we must do is calculate the z value for each value and thus find what percentage each represents and the subtraction would be the percentage between those two values.

We have that z is equal to:

z = (x - m) / (sd)

x is the value to evaluate, m the mean, sd the standard deviation

So for 80 we have:

z = (80 - 80) / (3)

z = 0

and this value represents 0.5

for 89 we have:

z = (89 - 80) / (3)

z = 3

and this value represents 0.9987

we subtract:

0.9987 - 0.5 = 0.4987

Which means that it represents 49.87%

A regular hex decagon's measure of one internal angle is 7.5 degrees more than a regular dodecagon's measure of one interior angle.

We must ascertain the measure of each individual angle in each polygon in order to compare the differences in one inside angle between a regular hex decagon and a regular dodecagon.

The following formula can be used to determine the size of each interior angle in a regular polygon with n sides:

Interior Angle = (n - 2) x 180 / n

Regular hex decagon:

Interior Angle = (16 - 2) * 180 / 16

= 14 * 180 / 16

= 2520 / 16

= 157.5 degrees

Regular dodecagon:

Interior Angle = (12 - 2) * 180 / 12

= 10 * 180 / 12

= 1800 / 12

= 150 degrees

Difference = Measure of hexadecagon angle - Measure of dodecagon angle

= 157.5 degrees - 150 degrees

= 7.5 degrees

Therefore, the measure of one interior angle of a regular hex decagon is 7.5 degrees greater than the measure of one interior angle of a regular dodecagon.

The solution of the differential equation is \(y = (48/t - 6t)^{-1/2}.\)

A differential equation is a mathematical equation that describes the relationship between a function and its derivatives.

In this particular differential equation, the dependent variable is y and the independent variable is t. The equation states that the rate of change of y with respect to t is equal to

=> y²(6 + t).

To find the solution to this differential equation, we first need to separate the variables and integrate both sides.

This gives us an equation of the form

\(= > y = (C/t - 6t)^{-1/2}\)

where C is an arbitrary constant.

To find the value of C, we use the initial condition y = 8 when t = 1. Plugging in these values, we find that

=> C = (8)² * 1 - 6 = 48.

So, the solution to the differential equation is

=> \(y = (48/t - 6t)^{-1/2}.\)

A triangle is a three-sided polygon whose sum of all the angles is always 180 degrees, not 90 degrees.

No, a triangle is not 90 degrees. In geometry, a triangle is a three-sided polygon with three angles. The sum of the angles in a triangle is always 180 degrees.

This can be proved using the fact that a straight line is 180 degrees. If we draw a straight line, and divide it into two angles, which are supplementary angles. Therefore, these angles add up to 180 degrees. In a triangle, we can draw one straight line and divide it into three angles, which are supplementary angles, therefore the sum of the angles in a triangle is always 180 degrees.

For example, if a triangle has angles of 90 degrees, 60 degrees, and 30 degrees, the sum of these angles is 180 degrees (90+60+30=180).

Therefore, In short, a triangle is a three-sided polygon whose sum of all the angles is always 180 degrees, not 90 degrees.
