What fraction is equal to 75% of 1/2

As per the given data, total distance run by Samaya is  20 2/3 miles in 2 1/4 hours then she can run 9 5 /27 miles per hour.

As given in the question,

Total distance run by Samaya is equal to 20 2/3 miles

Time taken by Samaya to run 20 2/3 miles is equal to 2 1/4 hours.

Number of miles per hour Samaya can run is equal to

20 2/3 miles = 2 1/4 hours

Convert the mixed fraction into proper fraction we get,

62 / 3 miles = 9 /4 hours

⇒ 1 hour = ( 62 / 3 ) × ( 4 / 9 ) miles per hour

⇒ 1 hour = ( 248 /27 ) miles per hour

⇒ 1 hour = (9 5/27) miles per hour.

Therefore, as per the given data, total distance run by Samaya is  20 2/3 miles in 2 1/4 hours then she can run 9 5 /27 miles per hour.

The complete question is:

Samaya can run 20 2/3 miles in 2 1/4 hours. How many miles per hour can she run?

The percent increase of the profit is 15%

In this question, the figures are given as

Profit in March = £2750

Profit in April = £3162.50

The percentage of the increase of the profit is then calculated using the following equation

Increase percentage = (Profit in April - Profit in March)/Profit in March * 100%

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

Increase percentage = (3162.50 - 2750)/2750 * 100%

Evaluate

Increase percentage = 15%

Hence, the increase in percentage is 15%

The graph which represents the velocity of the free-falling rock that changes during the first four seconds is option L: Same as “J” except the line is going from top left corner to bottom right corner.

What is velocity?

The pace at which an object's position changes in relation to a frame of reference and time is what is meant by velocity. Although it may appear sophisticated, velocity is just the act of moving quickly in one direction.

The velocity of a free-falling rock can depicted by equation of motion.

The first equation of motion, v = u + it is referred to as the velocity-time relation. On the other hand, the second equation of motion is s = ut + 1 / 2at² can be called the position-time relation. Likewise, we call the third equation of motion, v² = u²+ 2as, position – velocity relation.

The laws are: (1) Every object moves in a straight line unless acted upon by a force. (2) The acceleration of an object is directly proportional to the net force exerted and inversely proportional to the object's mass. (3) For every action, there is an equal and opposite reaction.

Since, the rock is falling freely it will form a straight line (first equation of motion) on the graph and not curved.

The rock will start to fall at an increasing speed with respect to time.

Therefore, option L is the correct answer.

Step-by-step explanation:

Answer:

(- 12, 10 )

Step-by-step explanation:

2x + 4y = 16 → (1)

- 2x - 3y = - 6 → (2)

add (1) and (2) term by term to eliminate x

0 + y = 10

y = 10

substitute y = 10 into (1) and solve for x

2x + 4(10) = 16

2x + 40 = 16 ( subtract 40 from both sides )

2x = - 24 ( divide both sides by 2 )

x = - 12

solution is (- 12, 10 )

Answer:

He would have to invest $80,412.

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

\(A(t) = P(1 + \frac{r}{n})^{nt}\)

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

Assuming an interest rate of 3,43% compounded quarterly.

This means that \(r = 0.0343, n = 4\)

How much would he have to invest to have $148,700 after 18 years?

This is P for which \(t = 18, A(t) = 148700\). So

\(A(t) = P(1 + \frac{r}{n})^{nt}\)

\(148700 = P(1 + \frac{0.0343}{4})^{72}\)

\(P = \frac{148700}{(1 + \frac{0.0343}{4})^{72}}\)

\(P = 80412\)

He would have to invest $80,412.

The volume of a 3-dimensional object is always strictly greater than zero.

Since a cylinder is a 3-dimensional object, then we must have that

V > 0

Also, the volume of the cylinder is finite.

Thus, V < ∞

Hence the domain of the inverse is (0, ∞)

Step-by-step explanation:

Supplementary angles are 2 angles that add up to 180 degrees. 180 degrees is also a line. So I picked angles that form a line.

The polynomial of degree 3 with zeros at x = 3, x = -4, and x = 5 is P(x) = x^3 - 4x^2 - 17x + 60.  

To construct a polynomial of degree 3 with zeros at x = 3, x = -4, and x = 5, we can use the fact that the polynomial can be written as a product of linear factors corresponding to each zero.

The factor corresponding to x = 3 is (x - 3).

The factor corresponding to x = -4 is (x + 4).

The factor corresponding to x = 5 is (x - 5).

To obtain the polynomial, we multiply these factors together:

P(x) = (x - 3)(x + 4)(x - 5)

Expanding this expression gives us:

\(P(x) = (x^2 - 3x + 4x - 12)(x - 5)\)

\(= (x^2 + x - 12)(x - 5)\)

\(= x^3 - 5x^2 + x^2 - 5x - 12x + 60\)

\(= x^3 - 4x^2 - 17x + 60\).

The residual value of the graph is 5.89

The residual for each observation is the difference between predicted values of y (dependent variable) and observed values of y

Given that, The equation of the least-squares regression line is

ŷ = 3.6 + 0.113x, where ŷ is the diagonal and x is the area of the rectangle.

We need to find the residual of the equation,

Residual = actual y value − predicted y value,

Therefore,

The equation is ;

ŷ = 3.6 + 0.113x

Let the diagonal be 4.472 in²

Finding for x,

y = 3.6 + 0.113(4.472)

y = 4.10

In the table, the value of y for the x = 4.472 in is 10, but here we get 4.10

Therefore, the residual value = 10-4.10 = 5.89

Hence, the residual value of the graph is 5.89

Given, the quadratic sequence is: 44:52:64:80

Sequences with a term are known as quadratic sequences. They can be distinguished by the fact that the first differences between terms are not equal but the second differences between terms are. Utilizing the term sum in an arithmetic progression formula, the sum of even numbers formula is achieved. The equation is Sum of Even Numbers Formula = n(n+1), where n is the total number of terms in the series.

The formula is: Tₙ = 2n² ₊ 2n  ₊ 40

take 2 common

Tₙ = 2(n² ₊ n  ₊ 20)
