Joni worked 14 hours more than Dominic last month. If Joni worked 7 hours for every 3 hours that Dominic worked, how many hours did they each work?

Answer:

0.35 feet per second

Step-by-step explanation:

To start, there's 3 feet in 1 yard.

So, we have to convert the 7 yards per minute to feet.

7 x 3 = 21

Then, we have to convert 21 feet per minute to X amount of feet per second.

To note, there are 60 seconds in a single minute

Therefore, you have to divide 21 by 60 to find the amount of feet in one second.

21 / 60 = 0.35

The answer is 0.35 feet per second

The angle ∠3 = 153° by alternate angle theorem.

Parallel lines are those lines that are equidistant from each other and never meet.

Parallel lines cut by a transversal, forms different angle relationship like alternate angles, corresponding angles, etc.

Line a and m are parallel lines . Therefore, angles 1, 2, 3, 4, 5, 153 degrees are related base on alternate and corresponding relationship.

Hence,

∠3 = 153°(alternate angles)

Alternate angles are congruent.

You need a value less than 23.5 or greater than 27.2.

Given the time in his first four races is: 24.7 , 23.5 , 25.6 , 27.2 seconds.

To find the time for her race which would make a higher difference, we need to make use of range.

The range formula is frequently employed in statistics to ascertain the range provided in a specific data set. The formula finds the difference between the lowest and highest value, which aids in locating the set's center. In distribution, a wide range denotes increased variability while a narrow range denotes lower variability. The mean, median, and mode are among the additional statistical concepts included in the range formula.

The range is the difference between the highest and lowest value. In this case, the highest and the lowest numbers are 27.2 and 23.5 seconds.

To make a larger range, we simply need to pick a number smaller than 23.5 or larger than 27.2. This will produce a larger difference (or range).

Hence we acquired the desired result.

To calculate marginal cost ; we use "subtract the quantity change from the overall cost change."

The potential cost of increasing orange output from 50 to 80 units was (250 – 200) = 50 cherries.

The potential cost of increasing cherry production from 100 to 200 units was (86-80) = 6 oranges.

Opportunity cost for an orange right now is,

equals 1.67 cherries.

Opportunity cost is therefore 3.34 cherries for two oranges.

The equations that are true are:

2 + 5 = 19 - 12

5 - 4 - 3 - 2 - 1 = 30 - 34 - 1

Here we have some equations, the equations are only true if we have the exact same number in both sides of the equation.

The first one is:

2 + 5 = 19 - 12

If we simplify both sides we get:

2 + 5 = 7

19 - 12 = 7

Then the equation becomes:

2 + 5 = 19 - 12

7 = 7

This is true.

The next equation is:

5 - 4 - 3 - 2 - 1 = 30 - 34 - 1

If we simplify both sides we get:

5 - (4 + 3 + 2 + 1) = 30 - 35

5 - 10 = 30 - 35

-5 = -5

This is true.

The last equation is:

2x + 5 - 4x = 3x - 2 - 5x + 16

Here we have a variable, so we need to solve this for x.

2x -4x + 5 = 3x - 5x + 16 - 2

Answer:

distance = [tex]\bf \sqrt{97}[/tex] units

Step-by-step explanation:

To find the distance between two points given their coordinates, we can use the following formula:

[tex]\boxed{\mathrm{distance} = \sqrt{(x_1-x_2)^2 + (y_1 - y_2)^2}}[/tex],

where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are coordinates of the two points.

The two points we are given are:

• J(-8, 0)

• K(1, 4).

Using these coordinates and the formula above, we can calculate the distance between the points:

distance = [tex]\sqrt{(-8 - 1)^2 + (0 - 4)^2}[/tex]

              = [tex]\sqrt{(-9)^2 + (-4)^2}[/tex]

              = [tex]\sqrt{81 + 16}[/tex]

              = [tex]\bf \sqrt{97}[/tex]

Therefore, the distance between J and K is [tex]\bf \sqrt{97}[/tex] units.

The dimensions of the rectangle are 10 inches by 25 inches

The given parameters are

The above parameters mean

w = 3l - 5

P = 70

The perimeter of the rectangle is

P =2(l + w)

So, we have

2(l + 3l - 5) = 70

Divide by 2

l + 3l - 5 = 35

Evaluate the like terms

4l = 40

Divide by 4

l = 10

Substitute l = 10 in w = 3l - 5

w = 3 * 10 - 5

Using integrals, it is found that the cumulative distribution function(cdf) at x = 2.27 is given by:

P(X ≤ 2.27) = 0.897.

The cumulative distribution function of a distribution given by f(x) at a value of x = x* is given by the following integral:

[tex]\int_{-\infty}^{x^{\ast}} f(x) dx[/tex]

For this problem, the distribution is given by:

[tex]f(x) = e^{-x}, x > 0[/tex]

Hence, at x = 2.27, the cdf is given by:

[tex]\int_{0}^{2.27} e^{-x} dx[/tex]

The infinity was replaced by 0 because the lower bound of the definition of the distribution is of 0. Hence:

[tex]\int_{0}^{2.27} e^{-x} dx = -e^{-x}|_{x = 0}^{x = 2.27}[/tex]

Applying the Fundamental Theorem of Calculus:

P(X ≤ 2.27) = -e^(-2.27) + e^0 = -e^(-2.27) + 1 = 0.897.

Domain of the function:

In interval notation: [6, ∞)

In set notation: {x: x∈R, x≥6}

Step-by-step explanation:

Remember that the the domain of the square root function are all the values such is is bigger than zero. We can express the later in set notation: {x: x∈R, x≥0}, or in interval notation: [0, ∞)

This is because the square root is not defined, in the real numbers, for negative values.

So, to find the domain of our function, we just need to set the thing inside the radical grater or equal than zero and solve for x:

The domain of the function is all the numbers bigger than 6, including 6.

Domain of the function: x will have values greater than or equal to 6 .

In interval notation: [6, ∞)

In set notation: {x: x∈R, x≥6}

Given, that function y = 2√x-6

Domain of the square root function are all the values which is greater than zero.

Express the later in set notation:

{x: x ∈ R, x≥0},

Interval notation: [0, ∞)

This is because the square root is not defined, in the real numbers, for negative values.

Domain of function y,

[tex]y= 2\sqrt{x-6}[/tex]

Using translation concepts, we have that:

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

On the translation of △ABC to △A′B′C′, the rule applied to the vertices is:

(x,y) -> (x + 4, y).

Hence it was translated 4 units right.

On the translation of △A′B′C′​ to △A′′B′′C′', the rule is given by:

(x,y) -> (-y,x).
