Answer: 60
Step-by-step explanation:
3 / 100 * x = 15
3x = 1500 multiply both sides by 100
x = 500
500x0.12 = 60
The 12 percentage of the number is A = 60
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage change is the difference between the measured value and the true value , as a percentage of the true value
Percentage change =( (| Measured Value - True Value |) / True Value ) x 100
Given data ,
Let's call the number we're looking for N
We can set up an equation based on the information given:
0.03N = 15
To solve for N, we can divide both sides by 0.03:
N = 15 / 0.03
N = 500
So the number we're looking for is 500
Now , the percentage value is = 12 %
And , we can find 12% of that number by multiplying it by 0.12:
A = 0.12 x 500 = 60
Hence , 12% of the number is 60.

originally, What is the estimated age of the artifact? (The half-life of 7. An archeologist finds an artifact that contains 44% of the carbon-14 that it would have had carbon-14 is 5,730 years.)
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 This means that the artifact contains 44% of the carbon-14 that it would have had when it was originally made.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.
The area of a right Triangle is 30 sq.cm and it’s perimeter is 30cm. If it’s hypotenuse is 13cm, what are the lengths of the other two sides?
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

Kiran is going to invest $6,600 and leave it in an account for 8 years. Assuming the
interest is compounded daily, what interest rate, to the nearest hundredth of a
percent, would be required in order for Kiran to end up with $9,500?
Answer:
Step-by-step explanation:1.08%
Interest rate required in order for Kiran to end up with $9,500 is 4.55%.
What is Compound Interest?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%
Hence the interest rate to the nearest hundredth of a percent is 4.55%.

A line has a slope of 1 and passes through the point (–12, –17) What is its equation in slope intercept form?
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).
What is Slope?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.

The height (in centimeters) of a candle is a linear function of the amount of time (in hours) it has been burning. When graphed, the function gives a line with a slope of "-0.5" . See the figure below. Suppose that the height of the candle after 19 hours is 16.5 centimeters. What was the height of the candle after 11 hours?
The height of the candle after 11 hours is 20.5 if the slope is -0.5.
What is a slope?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
Therefore, the height of the candle after 11 hours is 20.5

It takes 200 seconds to boil 2.7 litres of water.
Work out how much water is in the pot if it boils in 220 seconds.
The relationship between the time it takes to boil a pot of water, T (in seconds), and the amount of water, A (in litres),
T ∝ A,
setting up the equation and solving:
2.96 liters of water will boils in 220 seconds.
what is equation?An equation is a mathematical statement that shows that two expressions are equal.
what is proportionality constant?A proportionality constant is a coefficient that relates two quantities that are proportional to each other. In other words, if two quantities are proportional, their ratio is always the same, and this constant ratio is the proportionality constant.
This proportionality can be written as an equation by introducing a constant of proportionality, k:
T = k * A
We are given that it takes 200 seconds to boil 2.7 litres of water, so we can set up an equation using this information:
200 = k * 2.7
Solving for k, we find that k = 200/2.7 = 74.07407407407407.
Now that we know the value of the constant of proportionality, we can use it to find the amount of water in the pot if it boils in 220 seconds. We can set up the following equation:
220 = 74.07407407407407 * A
Solving for A, we find that the amount of water in the pot is A = 220 / 74.07407407407407 = 2.962962962962963 litres.

(please include explanation)
The exists no solution for which the water depth 14 feet in the ocean near the shore.
Explain the term time period?A time period (T) is the length of time it takes for one complete vibration cycle to pass over a certain location. As the frequency of a wave rises, so does its period. The length of time is expressed in "seconds."We determine the function's period since that is the number of it takes hours for the ocean to return to its original depth of a specific number of feet.
The function's duration is 2π/ (π/6.2) = 12.4 hours.
When t = 0, midnight, or 12:00AM, it is low tide.
As a result, the next low tide will occur at 12:24 PM, or t = 12.4, 12.4 hours from now.
A high tide will occur halfway between those two low tides, at t=6.2 hours after midnight, or at 6:12AM.
Another high tide will occur at t=18.6 hours after midnight, or at 6:36 PM, 12.4 hours later.
If t = 0 is used in the equation, the low tide occurs at that time;
d = 35 - 28cos(pi/6.2)t
d = 35-28cos(pi/6.2)0
d = 35-28cos(0)
d = 35-28(1)
d - 35-28
d = 7
Therefore, there will never be 4 feet there because the lowest depth that may exist is 7 feet.
Thus, the exists no solution for which the water depth 14 feet in the ocean near the shore.

⇒ t = [-14 ±√((14)² - 4*(-4)*1)]/-8
⇒ t = [-14 ±√(212)]/-8
⇒ t = [-14 ± 14.560]/-8
⇒ t = [-14 ± 14.560]/-8
⇒ t = -(28.56)/-8 and t = 0.560/-8
⇒ t = 3.750 and t = 0.070
hence, t = 3.750 and t = 0.070 are, the following x- values, between A) 0 and 1 and D) 3 and 4
