Answer 1

Answer: 26

Step-by-step explanation:

let t = thomas's age

104 = (3t) + t

104 = 4t

t = 26

Answer 2

Answer: 26 years old

Step-by-step explanation:

    We will write a system of equations to help us solve, let h be equal to Huilan's age and t be equal to Thomas's age.

         h = 3t

         h + t = 104

    Now, we will solve by substituting the first equation into the second.

    Then, we will simplify the equation on the left side by combining like terms and dividing both sides of the equation by 4 to isolate the variable.

         h + t = 104

         (3t) + t = 104

         4t = 104

         t = 26

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?

Answers

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%.

in an examination, the following was found 40% passed in mathematics 45% passed in science 55% passed in health. how many candidates passed in all three subjects?

Answers

5% of the students either passed all 3, or none of the tests.

What is amount ?

Mass nouns are referred to by the word amount. Count nouns are referred to as numbers.

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.

That gives

15+15+20 = 50% of the students passing only one course

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 %

15 - X%

And of course, the amount of students who passed all three exams: X.

This gives us

(15+X) + (15+X) + (20+X) + (10-X) + (20 - X) + (15 - X) + X = 100

95 + X = 100

X = 5

Or, 5% of students passed all 3 tests.

edit: this answer assumes all students pass at least one test. The actual summation should be: As pointed out with the first line, if that answer is

0%, the amount of students mentioned is 95%.

The actual answer is

5% of the students either passed all 3, or none of the tests.

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

Answers

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.

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.)

Answers

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.

A pebble is tossed into the air from the top of a cliff. The height of the pebble over time is modeled by the equation y = -16x2 + 32x + 80. What is the maximum height, in feet, reached by the pebble?

Answers

In linear equation,    x = 1  is the maximum height, in feet, reached by the pebble.

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 .

So,

        -32x + 32 = 0

  32x = 32

    x = 32/32

    x = 1

with the correct sampling method, you expect to obtain a sample mean exactly the same as the population mean. t or f

Answers

False. While using the right sampling technique can increase the probability of getting sample mean values that are close to population mean values.

What is the mean of population?

A population is the entire set of people in a group, whether that group is a country or a collection of people who share a certain trait. A population is the group of people from which a statistical sample is taken in statistics.

What is population mean and sample mean?

The sample mean is the mathematical average of values selected at random from the population. The population mean is a representation of the population's real mean.

It is impossible to ensure that the sample mean and population mean will be a perfect match. This is because sampling has intrinsic variability and randomness, which can cause discrepancies between the sample and the population even in studies that are carefully planned. Additionally, there could still be some variability or error in the estimates even if the sample mean is quite near to the population mean, which might have an impact on the accuracy of the findings.

Answers

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:

We can observe N + 2 is divisible by both 5 and 6, then it can be represented as:

N + 2 = 30m,

so

30m = 7q + 1 + 2 or30m - 3 = 7q

The left side is divisible by 3, then q = 3t:

30m - 3 = 7*3t10m - 1 = 7t

The least m and t would be m = 5 and t = 7.

Then:

N + 2 = 30*5 = 150 ⇒ N = 148 is the least possible number.

Proof:

148/5 = 29 (rem 3)148/6 = 24 (rem 4)148/7 = 21 (rem 1)

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?

Answers

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

How do parallel lines work?

In terms of geometry, parallel lines are two separate lines that never cross each other and are located in the same plane. They may be vertical or horizontal.

The equation of the parallel lines are;

y = x, and y = x + 1

The point of intersection of transversal 1 and the parallel lines y, and z

(0.2, 0.2), and (0.3, 0.8)

The length of segment AB = √((0.3 - 0.2)² + (0.8 - 0.2)²) = 0.1·√(37)

The point of intersection of transversal 1 and the parallel lines x, and y

(0.3, 0.8), and (0.4, 1.4)

The length of segment CB = √((0.4 - 0.3)² + (1.4 - 0.8)²) = 0.1·√(37)

The ratio of the lengths of the line segments formed by the transversal 1, AB:CB is found as  follows;

              AB/CB = 0.1 . √37/ 0.1 . √37  = 1

The point of intersection of transversal 2 and the parallel lines y and z are;

(0.8, 0.8), and (0.7, 1.2)

The length of segment EF = √((0.7 - 0.8)² + (1.2 - 0.8)²) = 0.1·√(17)

The point of intersection of transversal 2 and the parallel lines x and y are;

(0.7, 1.2), and (0.6, 1.6)

The length of segment DE = √((0.6 - 0.7)² + (1.6 - 1.2)²) = 0.1·√17

The ratio of the lengths of the line segments formed by the transversal 2, EF:DE is found as  follows;

                EF/DF  =  0.1 . √17/ 0.1 . √17 = 1

Therefore:

The ratio of the lengths of the two line segments formed on each transversal are equal.

                AB/CB = EF/DF
