Calculate the percent change. Then, describe
the change as an increase or decrease.
20 to 14

Answers

Answer 1

The percentage change from 20 to 14 is 30% decrease

How to determine the percentage change

From the question, we have the following parameters that can be used in our computation:

20 to 14

The final value (14) is less than the initial value (20)

So, the change is a percentage decrease

The change is then calculated as

Change = (Final value - Initial value)/Initial value * 100%

Substitute the known values in the above equation, so, we have the following representation

Change = (14 - 20)/20 * 100%

Evaluate

Change = -30%

Hence, the percentage decrease is 30%

The value of x and y in the parallel lines are 14 and 60 respectively.

How to find angles in parallel lines?

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate exterior angles, alternate interior angle, linear angles, vertically opposite angles etc.

Therefore, let's find the values of x and y in the parallel lines as follows:

4x + 12 = 68 (vertically opposite angles)

Vertically opposite angles are congruent.

Hence,

4x + 12 = 68

4x = 68 - 12

4x = 56

divide both sides by 4

x = 56 / 4

x = 14

Therefore, let's find the value of y.

68 + 2y - 8 = 180(same side interior angles)

Same side interior angles are supplementary

68 + 2y - 8 = 180

2y = 180 - 68 + 8

2y = 120

y = 120 / 2

y = 60

19.8

Step-by-step explanation:

The diameter of the base of the cylinder is equal to the diagonal of the inscribed square and is equal to the hypotenuse of an equilateral triangle into which the square is divided by diagonals ... By the Pythagorean theorem, the diameter (hypotenuse) is equal to the square root of the sum of the squares of the legs and is equal to 19.8

Suppose your city is building a new park, and issues bonds to raise the money to build it. You obtain a $1,000 bond that pays 5% interest annually that matures in 5 years. How much interest will you earn?

Answers

Answer:

To find out how much interest you will earn, you need to multiply the bond principal amount ($1,000) by the interest rate (5%) and the number of years the bond matures (5).

The interest rate is expressed as a percentage, so you need to convert it to a decimal by dividing it by 100.

Interest = Principal x Interest Rate x Time

Interest = $1,000 x 0.05 x 5

Interest = $1,000 x 0.05 x 5 = $250

So, you will earn $250 in interest over the 5-year period.

The acceleration function (in m/s2) and the initial velocity v(0) are given for a particle moving along a line.
The acceleration function (in m/s2) and the initial velocity v(0) are given for a particle moving along a line.
a(t) = 2t + 6, v(0) = −16, 0 ≤ t ≤ 5
(a) Find the velocity at time t.
v(t)=______ m/s
(b) Find the distance traveled during the given time interval.

Answers

By applying the definite integral, it can be concluded that the velocity at time t is v(t) = t² + 6t - 16, and the distance traveled during the given time interval is 36.67 meters.

Definite integral is the integral of a function whose values of the independent variables have a certain interval.

This kind of integral is frequently used for calculating the acceleration and velocity of a moving object.

a(t) = dv/dt

v(t) = ds/dt

To find the velocity at time t, we look at the given acceleration function:

    a(t) = dv/dt

2t + 6 = dv/dt

     dv = (2t + 6) dt

    v(t) = ∫(2t + 6) dt

          = t² + 6t + C

Knowing that v(0) = -16, we put this into the previous equation so we get C = -16

Now we have the velocity at the time t as follows:

v(t) = t² + 6t - 16

To find the distance traveled, we look at the velocity function:

           v(t) = ds/dt

t² + 6t - 16 = ds / dt

            ds = (t² + 6t - 16) dt

              s = ∫(t² + 6t - 16) dt

                 = 1/3t³ + 3t² - 16t + C

Then we calculate the distance traveled during 0 ≤ t ≤ 5:

s = s(5) - s(0)

  = (1/3 * 5³) + (3 * 5²) - (16 * 5) + C - 0 - 0 + 0 - C

  = 125/3 + 75 - 80

  = 125/3 - 5

  = 125/3 - 15/3

  = 110/3

  ≈ 36.67 meters.

Thus, the velocity at time t is v(t) = t² + 6t - 16, and the distance traveled during the given time interval is 36.67 meters.

Suppose that there are two types of tickets to a show: advance and same-day. The combined cost of one advance ticket and one same-day ticket is 60 . For one performance, 40 advance tickets and 15 same-day tickets were sold. The total amount paid for the tickets was 1400. What was the price of each kind of ticket?

Answers

Answer: Let's call the price of an advance ticket "a" and the price of a same-day ticket "s". We know that the combined cost of one advance ticket and one same-day ticket is 60, so we can set up the equation: a + s = 60.

We also know that 40 advance tickets and 15 same-day tickets were sold for a total of 1400 dollars. So we can set up the equation: 40a + 15s = 1400

We have a system of two equations with two variables. We can use substitution or elimination method to solve for the unknowns.

Using substitution:

Solve the first equation for s, s=60-a

substitute it into the second equation, 40a + 15(60-a) = 1400

Expanding the second equation: 40a + 900 - 15a = 1400

25a = 500

a = 20

substitute a back into the first equation: s = 60 - 20 = 40

So the price of an advance ticket is $20, and the price of a same-day ticket is $40.

Answers

lim [f(x) - g(x)] is9.

What is a limit of a function?

Generally, In mathematics, a limit is a value that a function "approaches" as the input of the function "approach" some value.

More formally, given a function f(x) and a value L, we say that "the limit of f(x) as x approaches a is L" if the values of f(x) can be made arbitrarily close to L by taking x sufficiently close to a, but not equal to a.

In other words, the limit of a function describes the behavior of the function as the input gets arbitrarily close to a particular value, but doesn't necessarily equal that value

The limit of the difference between the two functions is the difference of their individual limits. So,

lim [f(x) - g(x)] = lim f(x) - lim g(x)

= 7 - (-2)

= 9.

Is there sufficient evidence to conclude that less than 40% of U.S. adults are aware that such an investment would result in a sum of over $100,000? Test the relevant hypotheses using α =.05.

Answers

No, there is not. We do not have sufficient evidence to conclude that less than 40% of U.S. adults are aware that such an investment would result in a sum of over $100,000.

Two-Proportion Z-Test Results

To test the hypothesis that less than 40% of U.S. adults are aware that such an investment would result in a sum of over $100,000, we can use a two-proportion z-test. The null hypothesis is that the proportion of U.S. adults who are aware of the investment's outcome is equal to or greater than 40%, and the alternative hypothesis is that the proportion is less than 40%.

The test statistic is calculated as:

z = (p1 - p2) / √(p(1-p)(1/n1 + 1/n2))

where p1 is the proportion of U.S. adults in the sample who are aware of the investment's outcome (374/1010), p2 is the proportion assumed in the null hypothesis (0.4), and n1 and n2 are the number of observations in the sample and population, respectively.

Using these values, the test statistic is:

z = (0.369 - 0.4) / √(0.4(1-0.4)(1/1010)) = -1.08

Using a two-sided test with a significance level of 0.05, we can look up the critical value in a standard normal table or using software and find that the critical value is ±1.96. Since -1.08 is between -1.96 and 1.96, we fail to reject the null hypothesis.

Therefore, we do not have sufficient evidence to conclude that less than 40% of U.S. adults are aware that such an investment would result in a sum of over $100,000.

Answer:

Four hundred thirdy seven and six hundred and eight thousandths.

437.068

Step-by-step explanation:

Hope it helps! =D

The number formed by these terms is 437.068.

To solve this problem, we first need to understand the place value system and what each term represents.

As per the place value system used in decimals:

- Hundreds: It is the third digit to the left of the decimal point and each unit represents 100.
- Tens: It is the second digit to the left of the decimal point and each unit represents 10.
- Ones: It is right next to the decimal point, all the digits to the left of it are the ones. Each unit represents 1.
- Hundredths: It is the second digit to the right of the decimal point and each unit represents 0.01.
- Thousandths: It is the third digit to the right of the decimal point and each unit represents 0.001.

In the given context, we know that there are 4 hundreds, 3 tens, 7 ones, 6 hundredths, and 8 thousandths.

To start, we calculate each term separately:

- 4 hundreds = 4 x 100 = 400
- 3 tens = 3 x 10 = 30
- 7 ones = 7 x 1 = 7
- 6 hundredths = 6 x 0.01 = 0.06
- 8 thousandths = 8 x 0.001 = 0.008

After evaluating each term separately, we sum them up together for the final answer:

- Sum = 400 + 30 + 7 + 0.06 + 0.008 = 437.068

Hence, the number formed by these terms is 437.068.

Given:

mean μ = 34standard deviation σ = 2

To find the two values between which 95% of the data lies, subtract and add two standard deviations to the mean:

⇒ μ - 2σ = 34 - 2(2) = 34 - 4 = 30

a constant volume of cookie dough is formed into a cylinder with a relatively small height and large radius. when the cookie dough is placed into the oven, the height of the dough decreases as the radius increases, but it retains its cylindrical shape. at time t, the height of the dough is 6 mm, the radius of the dough is 20 mm, and the radius of the dough is increasing at a rate of 2 mm per minute. Part A: At time t, at what rate is the area of the circular surface of the cookie dough increasing with respect to time? (5 points)
Part B: At time t, at what rate is the height of the dough decreasing with respect to time?

Answers

So, the rate at which the area of the circular surface of the cookie dough is increasing with respect to time is 80π mm^2/min and the rate at which the height is decreasing with respect to time is  -2 mm/min.

Part A: The area of the circular surface of the cookie dough is given by A = πr^2, where r is the radius of the dough. The rate at which the area is changing with respect to time is given by dA/dt = 2πr*dr/dt. At time t, the radius is 20 mm and the rate at which it is increasing is 2 mm/min. Therefore, the rate at which the area of the circular surface of the cookie dough is increasing with respect to time is dA/dt = 2π(20 mm)(2 mm/min) = 80π mm^2/min.

Part B: The height of the dough is given by h, and the rate at which the height is decreasing with respect to time is given by dh/dt. Since the dough is retaining its cylindrical shape, the decrease in the height of the dough is exactly the opposite of the increase in the radius. At time t, the rate at which the radius is increasing is 2 mm/min, so the rate at which the height is decreasing with respect to time is dh/dt = -2 mm/min.

The perimeter of a rectangle can be represented by a polynomial expression. The expression will consist of two terms, one representing the width and one representing the length. Each term will contain a variable, which is to the power of one, multiplied by a coefficient. The sum of the two terms produces the perimeter of the rectangle.

For example, if the width of the rectangle is w and the length is l, then the polynomial expression for the perimeter would be: P = w + l. This expression can also be written in expanded form as: P = w + w + l + l.

By adding more terms to this polynomial expression, the perimeter of more complex rectangles can be found. For example, if the rectangle is not a perfect square, then two additional terms can be added to the polynomial expression. One term will represent the extra width and one term will represent the extra length. By adding these two additional terms, the perimeter of the rectangle can be calculated.

In conclusion, the perimeter of a rectangle can be represented as a polynomial expression, which consists of terms that have variables raised to the power of one and are multiplied by coefficients. By adding more terms to the expression, the perimeter of more complex rectangles can be found.

What was Di's average velocity, in miles per hour, from the interval
t = 10 min
to
t = 15 min?
(Round your answer to two decimal places.)

Answers

Average velocity between the interval t = 10 min to t = 15 min is; 52.5 miles per hour

How to find the average velocity?

The expression showing  Di's average velocity, in miles per hour, t minutes after entering the interstate highway is;

v(t) = ¹/₂₀₀t³ + ³/₂₀t² - ³/₈t + 60

At t = 10 minutes, we have;

v(10) = ¹/₂₀₀(10³) + ³/₂₀(10²) - ³/₈(10) + 60

v(10) = 5 + 15 - 7.5 + 60

v(10) = 52.5 miles per hour

At t = 15 minutes, we have;

v(15) = ¹/₂₀₀(15³) + ³/₂₀(15²) - ³/₈(15) + 60

v(15) = 16.875 + 33.75 - 5.625 + 60

v(15) = 105 miles per hour

Thus;

Average velocity between the interval t = 10 min to t = 15 min is;

v(15) - v(10) = 105 - 52.5

= 52.5 miles per hour

“One-third of a herd of elephants and three times the square root of the remaining part of the herd were seen on a mountain slope; and in a lake was seen a male elephant along with three female elephants constituting the ultimate(last) remainder. How many were the elephants here?”

Answers

The total number of elephants in the herd is 24.

How did we arrive at the value?

This is a math problem that can be solved using algebra. To start, let x be the total number of elephants in the herd.

From the first part of the problem, we know that:

x/3 = a herd of elephants seen on a mountain slope

From the second part of the problem, we know that:

3 * √(x - x/3) = a herd of elephants seen on a mountain slope

From the third part of the problem, we know that:

1 + 3 = 4 = the ultimate remainder of the herd seen in a lake.

We can then use these equations to solve for x.

x/3 + 3 * √(x - x/3) + 4 = x, where x is the total number of elephants in the herd.

x = 3 * (1 + √(x - x/3) + 4)

Solving for x, we get x = 24

So, the total number of elephants in the herd is 24.

The coordinate of P that divides line AB in the ratio 4:1 is (6.6, 3.8)

What is an equation?

An equation is an expression that shows the relationship between numbers and variables.

If a point O(x, y) divides line segment AB with endpoints A(x₁, y₁) and B(x₂, y₂) in the ratio of n:m. The coordinates of O is:

[tex]x = \frac{n}{n+m}(x_2-x_1)+x_1 \\\\y = \frac{n}{n+m}(y_2-y_1)+y_1[/tex]

Given that P(x, y) divides line AB in the ratio 4:1. The coordinates are A(1, 3) and B(8, 4). Therefore:

[tex]x=\frac{4}{4+1}(8-1) +1=6.6\ unit\\\\y=\frac{4}{4+1}(4-3) +3=3.8\ unit[/tex]

The coordinate of P is (6.6, 3.8)
