Ellen makes $20 per hour in her job as a kiental assistant. She works 8 hours per day and 40 hours per week. How much does Ellen make in a day before taxes?

Money earned by Ellen per hour = $20.

Number of hours she works per day = 8 hours.

Money she'll make per day = 20×8 = 160

Hence, the answer is $160.

Answer:

27/4 units^3

Step-by-step explanation:

V= area of the base × length

V= 3 3/8 × 2

= 27/4 units^3

Answer:

6 1/4 units ^3

Step-by-step explanation:

The volume is given by

V = Bh  where B is the area of the base and h is the height

V = 3 3/8 *2

Changing to improper fractions

V = (8*3+3)/8 *2

    = 27/8 *2

    = 27 * 2/8

     =27/4

Changing back to a mixed number

    = 6 1/4

Step-by-step explanation:

Given,

T=6years

R=3.2%

A=86125

Now,

CA=P[1+R/10]^T

The required coordinates of point B are (-3, 7) where point M is the midpoint of AB.

A midpoint is defined as in the middle of the line connecting two points a position known as a midpoint. A location in the middle of a line connecting the two points that are equally far from both points is the midpoint.

Point A is located at (1, 5), and point M is located at (-1, 6). If point M is the midpoint of AB

We can use these coordinates to find the coordinates of point B, which is the midpoint of line segment AB.

Let the coordinates of B would be (x, y)

Substituting the coordinates of points A into the midpoint formula gives us :

-1 = (x+1)/2 ; 6 = (y+5)/2

-2 = x +1 ; 12 = y + 5

x =  -3; y = 7

Therefore, the required coordinates of point B are (-3, 7).

Answer:

7.2kg of flour

Step-by-step explanation:

Total weight of bread = 10 x 750g

                                    = 7500g = 7.5kg

500g of bread = 480g of flour

0.5kg of bread = 0.48kg of flour

7.5kg of bread = 7.2kg of flour

Answer:

62,500 pi

Step-by-step explanation:

diameter = radius + radius

d = 2r

r = d/2

A = 4pi r^2

= 4 pi (d/2)^2

= 4pi d^2/4

= 4pi* 250^2/4

= 4pi * 62,500/4

= 4pi * 15625

= 62,500 pi

Answer:

1 solution

Step-by-step explanation:

the two equations only cross once

The system of equations may have either 2 or 1 solution, but we cannot determine the exact number of solutions without further information or analysis.

We have,

The given system of equations consists of two equations in two variables:

y = (-1/3)x + 7 _______(1)

y = -2x³ + 5x² + x - 2 _______(2)

To find the solutions of the system, we need to find the values of x and y that satisfy both equations simultaneously.

Since both equations are in the form y = ...,

we can set the expressions on the right-hand sides of the equations equal to each other:

(-1/3)x + 7 = -2x³ + 5x² + x - 2

Rearranging and simplifying, we get:

2x³ - 5x² - (2/3)x + 9 = 0

To solve for x, we can use factoring or the rational root theorem.

However, the polynomial on the left-hand side of the equation does not appear to have any rational roots or easily factorable forms.

Therefore, to determine the number of solutions,

we can use Descartes' rule of signs to find the possible number of positive and negative roots of the polynomial:

The number of positive roots is either equal to the number of sign changes in the coefficients or less than it by an even integer.

There are two sign changes in the coefficients, so there can be either 2 or 0 positive roots.

The number of negative roots is either equal to the number of sign changes in the coefficients or less than it by an even integer.

There is one sign change in the coefficients, so there can be either 1 or 0 negative roots.

Since the sum of the possible number of positive and negative roots is either 2 or 1, the total number of solutions is either 2 or 1.

Therefore,

The system of equations may have either 2 or 1 solution, but we cannot determine the exact number of solutions without further information or analysis.

The area of the patio not taken up by the fountain is 241ft²

Please find attached an image of the patio

Area of the patio not taken up by the fountain = area of patio - area of fountain

The patio is in a shape of a trapezoid. Thus, the area of the patio can be determined by using the formula for the area of a trapezoid

A trapezoid is a convex quadrilateral. A trapezoid has at least on pair of parallel sides. the parallel sides are called bases while the non parallel sides are called legs

Characteristics of a trapezoid

Area of a trapezoid =  0.5 x (sum of the lengths of the parallel sides) x height

Taking a look at the image, we are not provided with the height of the trapezoid, just the parallel sides and the hypotenuse.

Pythagoras theorem can be used to determine the the height of the trapezoid

The Pythagoras theorem : a² + b² = c²

where a = height  

b = base = 20 ft - 12 ft = 8ft

8ft / 2 = 4

c =  hypotenuse

a² + 4² = 25²

a² = 625 - 16

a² = 609

√609 = 24.68 ft

Area of the trapezoid = 0.5 x (20 + 12) x 24.68 = 394.88 ft²

The fountain is in the shape of  a circle.

Area of a circle = πr²

Where : = π = pi = 22/7

R = radius  

The radius would have to determined from the circumference

circumference of a circle = 2πr

14π = 2πr

r = 14π / 2π

r = 7

Area of the circle = [tex]\frac{22}{7}[/tex] × 7²

[tex]\frac{22}{7}[/tex] × 49 = 154 ft²

Area of the patio not taken up by the fountain = 394.88 ft² - 154 ft² = 240.88ft²

To round off to the nearest square, look at the first number after the decimal, if it is less than 5, add zero to the units term, If it is equal or greater than 5, add 1 to the units term.

The tenth digit is greater than 5, so one is added to 0. The number becomes 241ft²

Answer:

k = 3

Step-by-step explanation:

If the points lie on the same line then the slope between the points will be equal.

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, 4) and (x₂, y₂ ) = (- 3, 16)

m = [tex]\frac{16-4}{-3-1}[/tex] = [tex]\frac{12}{-4}[/tex] = - 3

Repeat the process and equate to - 3

with (x₁, y₁ ) = (1,4) and (x₂, y₂ ) = (k, - 2)

m = [tex]\frac{-2-4}{k-1}[/tex] = [tex]\frac{-6}{k-1}[/tex] , then

[tex]\frac{-6}{k-1}[/tex] = - 3 ( multiply both sides by k - 1 )

- 6 = - 3(k - 1) ← divide both sides by - 3

2 = k - 1 ( add 1 to both sides )

3 = k

The construction illustrated in the figure is that of a line parallel to [tex]\overrightarrow{HJ}[/tex] through point N.

Given: Figure containing illustration of the construction

To find: The construction illustrated in the figure

It can be seen that the figure contains a straight line passing through H and J, a straight line passing through H and N, and a straight line passing through N which seems to be parallel to [tex]\overrightarrow{HJ}[/tex].

The figure also contains arcs made by a compass that measures the angle between [tex]\overrightarrow{HJ}[/tex] and [tex]\overrightarrow{HN}[/tex]. These arcs have been replicated at the point N on the straight line [tex]\overrightarrow{HN}[/tex].

This implies that the straight line through N has been constructed in such a way, so that the angle between that straight line and [tex]\overrightarrow{HN}[/tex] is equal to the angle between [tex]\overrightarrow{HJ}[/tex] and [tex]\overrightarrow{HN}[/tex]. This makes these angles, corresponding angles and [tex]\overrightarrow{HN}[/tex] as the transversal. Thus, the new straight line is constructed parallel to [tex]\overrightarrow{HJ}[/tex].

A strong counterargument that this illustration is not that of a line perpendicular to [tex]\overrightarrow{HJ}[/tex] through point N is that the figure does not contain any straight line perpendicular to [tex]\overrightarrow{HJ}[/tex].

Thus, the construction illustrated in the figure is that of a line parallel to [tex]\overrightarrow{HJ}[/tex] through the point N.
