8) Which ratio would be equivalent to 1/9 ? *
OA) 3/18
OB) 2/27
OC) 3/27
D) 3/10

Answer: To determine the estimated age of the artifact, we can use the half-life of carbon-14 and the percentage of carbon-14 that is present in the artifact.

The half-life of carbon-14 is the amount of time it takes for half of the carbon-14 in a sample to decay. In this case, the half-life of carbon-14 is 7,730 years.

The percentage of carbon-14 that is present in the artifact is 44%. This means that the artifact contains 44% of the carbon-14 that it would have had when it was originally made.

To determine the age of the artifact, we can use the formula:

age = (half-life / log(2)) * log(percentage of carbon-14 / 100)

Substituting the values from the problem into the formula, we get:

age = (7,730 years / log(2)) * log(44% / 100)

age = (7,730 years / 0.693) * log(0.44)

age = 11,095 years * (-0.847)

age = -9,432 years

Therefore, the estimated age of the artifact is -9,432 years.

It is important to note that this is just an estimate, and the actual age of the artifact may be different. Carbon-14 dating is only accurate up to a certain point, and the accuracy of the age determination depends on several factors, including the initial concentration of carbon-14 in the sample and the presence of any contaminants.

Inequality is 2x+178 >=2000. and Solution set is x>=911 i.e., the no: of cans that Shane should have collected

The idea of inequality, which is the state of not being equal, especially in terms of status, rights, and opportunities1, is at the core of social justice theories. However, because it frequently has different meanings to different people, it is prone to misunderstanding in public discourse. However, some distinctions are shared.

Lifetime Inequality (the distribution of incomes across households or individuals over a person's lifetime), Inequality of Wealth (the distribution of wealth across households or individuals at a particular point in time), and Inequality of Opportunity (the impact on income of factors that people cannot control) are all related concepts.

Let the number of cans collected by Shane = x and the number of cans collected by Abha = y.

It is given that, Abha collected 178 cans more than Shane.

So, we have, .

Since, they both have to collect cans no less than 2000 i.e. greater than or equal to 2000.

So, the equation representing the situation is,

Shane + Abha ≥ 2000

i.e. y + x ≥ 2000

Thus, by substitution we have,

Inequality for the number of cans Shane collected is .2x+178 >=2000.

Solution set of the inequality is x>=911.

Answer:

either h=12, b=5

or h=5, b=12

Step-by-step explanation:

We'll use a system of equations to solve this. We'll have 2 equations and 2 unknowns. Our 2 unknowns are the 2 other sides, and our 2 equations are as follows:

look for any information given. I see that the area is 30 sq.cm and the perimeter is 30cm. There are our pieces of information.

Our first equation will be the one about how the area is 30 sq.cm (we'll use b for base and h for height:

(1/2)×b×h=30

Our second equation will be the one about how the perimeter is 30cm:

13+b+h=30

These equations both have to be true at the same time, and there are a few techniques for solving a system of equations, but in this case, this way is probably the simplest. We'll get one variable on one side of an equation and then plug it into the other equation using the transitive property.

13+b+h=30

b=30-13-h

b=17-h

now we'll plug in (17-h) for all the b in the first equation:

(1/2)×(17-h)×h=30

17h-h²=60

-h²+17h-60=0

now we'll use quadratic formula (or factor) to find h:

[-17±√(289-240)]/-2

(-17±7)/-2

-24/-2 or -10/-2

12 or 5

h=12

h=5

we'll try both of them in this equation:

13+b+h=30

25+b=30

or 18+b=30

therefore;

either h=12, b=5

or h=5, b=12

Step by Step:

The slopes and points are:

The height of the candle after 11 hours is 20.5 if the slope is -0.5.

The ratio of "vertical change" to "horizontal change" between any two separate points on a line, or any two points, is used to compute slope. When the ratio is expressed as a quotient ("rise over run"), the same number is provided for every two distinct locations on the same line. There is a negative "rise" on a descending line. The line may be practical, as determined by a road surveyor, or in a diagram that represents a roof or a road as a description or a design.

The absolute value of the slope serves as a proxy for a line's steepness, incline, or grade.

Given, slope m= -0.5

(y-y₁)=m(x-x₁)

Also given that,

x=19, y=16.5 cm

(y-16.5)=m(x-19)

y-16.5= -0.5(x-19)

y-16.5= -0.5x+9.5

0.5x+y-26=0

After 11 hours, the height of the candle is:

x=11

0.5(11)+y-26=0

y=26-5.5

y=20.5

Step-by-step explanation:

To calculate the total area of the cylinder, we need to use the formula for calculating surface area; SA = 2πr² + 2πrh. In this case, r is equal to 1.5 yards and h is equal to 24 yards:

SA = 2(3.14)(1.5^2) + (2)(3.14)(1.5)(24)

To illustrate the process of thinking, tets assume there are no people who passed all subjects.

40% (Maths) - 10%(+sceince) - 15% (+english) = 15% only maths

45% - 10% - 20% = 15% only science

55% - 20% - 15% = 20% only english.

10+20+15 = 45% of students passing only 2 courses

… that’s 95% together …

… but we need to get to 100%; obviously.

If we assume there are X% students that passed in all 3 courses, then from the first line, we substracted this person twice: (once for +science, and once for +english). Considering we only need to substract ’m once, that’s the same as substracting twice and adding once. we get:

40% (Maths) - 10%(+sceince) - 15% (+english) + X% = 15+X % only maths

and likewise

45% - 10% - 20% + X= 15 +X % only science

55% - 20% - 15% +x X= 20 +X % only english.

Now, for the students who passed exactly 2 classes, that’s

10 - X % only maths and science

20 - X %

Solve for x.

Equation of the line in slope intercept form is y = x - 5, when slope is 1 and a point on the line is (-12, -17).

Slope of a line is the degree of inclination of that line.

In other words, slope of a line can be calculated by taking the change in y coordinates to the change in x coordinates when x coordinate and y coordinate of two points are given.

Equation of a line in slope-intercept form is,

y = mx + c

where, m is the slope and c is the y-intercept.

y- intercept is the y-coordinate of a point where the line touches with the Y-axis. x coordinate will be zero at this point.

We have m = 1 and a point (x, y) = (-12, -17)

Substituting these values in the equation,

-17 = (1 × -12) + c

-17 + 12 = c

c = -5

Substituting m = 1 and c = -5, equation in slope intercept form can be written as,

y = x - 5

Hence, the equation of the line in slope intercept form when slope = 1 and passing through the point (-12, -17) is y = x - 5.

Interest rate required in order for Kiran to end up with $9,500 is 4.55%.

Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.

Given,

Principal amount = $6,600

Time in years = 8 years

Final amount = $9,500

The final amount is calculated in compound interest by the formula,

A = P (1 + [tex]\frac{r}{n}[/tex]) ^ (n t)

Here, P is the principal amount, r is the rate of interest, n is the number of  years.

Substituting in the formula,

9500 = 6600 (1 + [tex]\frac{r}{365}[/tex]) ^(365 × 8)

9500 / 6600 = (1 + [tex]\frac{r}{365}[/tex])²⁹²⁰

1.4394 = (1 + [tex]\frac{r}{365}[/tex])²⁹²⁰

1.000125 = 1 + [tex]\frac{r}{365}[/tex]

[tex]\frac{r}{365}[/tex] = 0.00125

r = 0.045531

r = 4.5531% ≈ 4.55%

What in mathematics is a linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept.

                                  Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

The height of the pebble over time is modeled by the equation

        y = -16x2 + 32x + 80

At the maximum height, the final velocity of the pebble is zero.

The velocity of the pebble will be obtained by taking the derivative of the given equation.

That is

                y' = dy/dx

                    = d/dx (-16x2 + 32x + 80 )

                    = -32x + 32

At the maximum height, y' = 0 .
