Amount saved by Nicole is $ 105

Solution:

Given that Patrician saves $ 1.20 everyday and Nicole saves $ 2.80 daily

The two girls saved $ 150.00 together

To find: Amount saved by Nicole

Let "x" be the number of days for which Patrician and Nicole saved money

Given that they both saved $ 150.00 together

So we can frame a equation as:

[tex]\text{(amount saved by patrician + amount saved by nicole) } \times x = 150.00[/tex]

[tex](1.20 + 2.80) \times x = 150\\\\4x = 150\\\\x = 37.5[/tex]

Therefore amount saved by nicole:

Nicole has saved $ 2.80 daily for "x" days

[tex]\text{ Amount saved by Nicole } = x \times 2.80\\\\\text{ Amount saved by Nicole } = 37.5 \times 2.80 = 105[/tex]

Thus amount saved by Nicole is $ 105

[tex]A_{new}=9A_{original}[/tex]

Step-by-step explanation:

The are of a trapezoid is:

[tex]A_{original}=\frac{(a+b)}{2}h[/tex]

where:

When a geometric figure dilates, every coordinate of the original figure must be multiplied by the scale factor of this dilatation. In our case this factor is 3, therefore we will have:

[tex]A_{new}=\frac{(3a+3b)}{2}3h[/tex]

[tex]A_{new}=9\frac{(a+b)}{2}h[/tex]

[tex]A_{new}=9A_{original}[/tex]

Answer:

Step-by-step explanation:

Chrissie likes to tip a server in a restaurant a minimum of 25% of her lunch bill. She and her friend have a lunch bill that is $13.78. This means that the amount of tip that she would give to the server would be

25/100 × 13.78 = 0.25 × 13.78 = $3.445

If Chrissie says the tip will be $3.00, he is incorrect because the tip is $3.445 which is higher than $3

If her friend says that the amount is not a minimum of 25% he is correct because a minimum if 25% is $3.445 which is higher than $3

Answer:

D

Step-by-step explanation:

Remember how absolute values turn everything inside of it into a positive number? Like |-4|=4 and |4|=4 as well.

Well, it works the same for equations.

When you have an absolute value equation like this, you have to split it into two parts.

The positive version

| d-3.5 | ≤ 1.5

and the negative version

|-(d-3.5)| ≤ 1.5

solve for the value of d in both equation.

Remember that you have to flip the inequality sign when dividing or multiplying by a negative number

I assume you know how to graph the inequality once you get the value for d.

d≤5 and d≥2

so

2 ≤ d ≤ 5

meaning d is between 2 and 5.

Answer:

  (-10, -6), (4, -6), (-3, -13), (-3, 1)

Step-by-step explanation:

The easiest points to find that have rational coordinates are the ones 7 units up or down, left or right from the given point. Those are listed above.

We used the distance formula to find four points that could serve as the other end of a line segment with one end at (-3, -6) and length of 7 units. The four points are (0, -6 + √40), (0, -6 - √40), (-3 + √13, 0), and (-3 - √13, 0).

Finding the Other End Point of a Line Segment

To find four points that can serve as the other end point of a line segment with one end point at (-3, -6) and a length of 7 units, we use the distance formula. The distance formula is:

Distance = √((x₂ - x₁)² + (y₂ - y₁)²)

Given, (x₁, y₁) is (-3, -6) and the distance is 7, we need to find (x₂, y₂) such that:

√((x₂ + 3)² + (y₂ + 6)²) = 7

Squaring both sides: (x₂ + 3)² + (y₂ + 6)² = 49

(0 + 3)² + (y₂ + 6)² = 49

9 + (y₂ + 6)² = 49

(y₂ + 6)² = 40

y₂ + 6 = ±√40

y₂ = -6 ± √40

(x₂ + 3)² + (0 + 6)² = 49

(x₂ + 3)² + 36 = 49

(x₂ + 3)² = 13

x₂ + 3 = ±√13

x₂ = -3 ± √13

Thus, the four possible points for the other end point of the line segment are (0, -6 + √40), (0, -6 - √40), (-3 + √13, 0), and (-3 - √13, 0).

Answer:

Therefore the THREE roots are

[tex]x=0\ or\ x=-3\ or x=-4[/tex]

Step-by-step explanation:

Given:

[tex]x^{3}+7x^{2} +12x= 0[/tex]

To Find:

All  the Roots = ?

Solution:

As the degree of the polynomial is THREE then the number of root are also THREE.

[tex]x^{3}+7x^{2} +12x= 0\\\\x(x^{2}+7x +12)= 0\\\\x=0\\or\\x^{2}+7x +12= 0\\[/tex]

Now one root is Zero For other we need to Factorize

So by Splitting the middle term

i.e Factor of 12 such that sum should be 7

i.e 3 × 4 = 12  and 3 + 4 = 7

∴ [tex]x^{2}+7x +12= 0\\x^{2}+3x+4x +12= 0\\x(x+3)+4(x+3)=0\\(x+3)(x+4)=0\\\\x+3=0\ or\ x+4 = 0\\\\\therefore x=-3\ or x=-4\ \textrm{Which are the roots}[/tex]

Therefore the THREE roots are

[tex]x=0\ or\ x=-3\ or x=-4[/tex]

Answer:

  24/7 = 3 3/7 inches

Step-by-step explanation:

The triangle can be represented by a line in the first quadrant with y-intercept 8 and x-intercept 6. Then its equation is ...

  x/6 +y/8 = 1 . . . . . intercept form of the equation of the line

  4x + 3y = 24 . . . . multiply by 24 to get standard form

Since the square will have the origin as one corner, and all sides are the same length, the opposite corner will lie on the line y=x. Then we're solving the system ...

  4x +3y = 24

  y = x

to find the side length.

__

By substitution for y, this becomes ...

  4x +3x = 24

  7x = 24

  x = 24/7 = 3 3/7

The length of the side of the square is 3 3/7 inches.

The question involved finding the side length of a square inscribed in a right triangle. The correct approach uses additional geometry to set up a system of equations resulting from segments on the legs of the triangle equal to the side length of the square. Solving these equations reveals that the side length of the square is 2 inches.

The student is seeking to find the length of the side of a square inscribed in a right triangle with legs measuring 6 inches and 8 inches. To determine this, one can use the Pythagorean theorem which relates the legs of a right triangle to its hypotenuse. However, in this scenario, the side of the square also acts as a 'leg' of two smaller right triangles within the original triangle. The length of the square, let's call it 's', plus the square's length (again 's') will equal the longer leg of the triangle (8 inches); similarly, 's' plus the length from the corner of the square to the right angle of the triangle (which is also 's') will equal the shorter leg (6 inches).

Therefore, we have two equations: 2s = 8 and 2s = 6. Since both cannot be true with the same value of 's', we realize that the premise of the question must be reconsidered. The actual process involves a bit more geometry, using the fact that the segments along the legs that are not part of the square must be equal respectively, leading to a system of equations to solve for the length of the side of the square. Let's denote these segments as 'x'; hence the equations are s + x = 6 and s + x = 8. Subtracting these equations from the original leg lengths gives us x = 6 - s and x = 8 - s. As these segments are equal, we can set them equal to each other, getting 6 - s = 8 - s, which simplifies to s = 2 inches.

Answer: The value of 528 would change by 40 if 6 replaced 2

Step-by-step explanation:

The given number is 528. If we replace 2 by 6, the new number becomes 568. This is greater than the previous number. The difference between the new number and the previous number would be

568 - 528 = 40

Answer:one piece is 42 centimeters and the other piece is 14 centimeters

Step-by-step explanation:

Let x represent the length, in centimeters, of one piece of the ribbon.

Let y represent the length, in centimeters, of the other piece of the ribbon.

The ribbon, 56 cm long is cut into two pieces. This means that

x + y = 56 - - - - -- - - - -1

One of the pieces is three times longer than the other. This means that

x = 3y

Substituting x = 3y into equation 1, it becomes

3y + y = 56

4y = 56

y = 56/4 = 14 centimeters

x = 3y = 2×14 = 42 centimeters

Answer: the price of 1 yard of chicken wire is $2

Step-by-step explanation:

Let x represent the cost of one yard of landscaping fabric.

Let y represent the cost of one yard of chicken wire.

Charlotte pays $24 for 3 yards of landscaping fabric and 6 yards of chicken wire. This means that

3x + 6y = 24 - - - - - - - - - - 1

Kami pays $30 for 6 yards of landscaping fabric and 3 yards of chicken wire. This means that

6x + 3y = 30 - - - - - - - - -2

Multiplying equation 1 by 6 and equation 2 by 3, it becomes

18x + 36y = 144

18x + 9y = 90

Subtracting

27y = 54

y = 54/27 = 2

Substituting y = 2 into equation 1, it becomes

3x + 6×2 = 24

3x = 24 - 12 = 12

x = 12/3 = 4

Answer:

$2 per yard.

Step-by-step explanation:

Let the price per yard of landscaping fabric be f and the price of chicken wire per yard be c.

3f + 6c = 24     Multiply this equation by  - 2:

-6f - 12c = -48 Also:

6f + 3c = 30

Adding the last 2 equations:

-9c = -18

c = 2.

Answer:  The correct option is

(E) 70.

Step-by-step explanation:  We are given to find the number of  triangles and quadrilaterals altogether that can be formed using the vertices of a 7-sided regular polygon.

To form a triangle, we need any 3 vertices of the 7-sided regular polygon. So, the number of triangles that can be formed is

[tex]n_t=^7C_3=\dfrac{7!}{3!(7-3)!}=\dfrac{7\times6\times5\times4!}{3\times2\times1\times4!}=35.[/tex]

Also, to form a quadrilateral, we need any 4 vertices of the 7-sided regular polygon. So, the number of quadrilateral that can be formed is

[tex]n_q=^7C_4=\dfrac{7!}{4!(7-4)!}=\dfrac{7\times6\times5\times4!}{4!\times3\times2\times1}=35.[/tex]

Therefore, the total number of triangles and quadrilaterals is

[tex]n=n_t+n_q=35+35=70.[/tex]

Thus, option (E) is CORRECT.

To solve for x, the given inequality (7 - 2x) / (-4) + 2 < -x can be simplified by isolating the variable on one side of the inequality. The value of x is found to be x < -15/2, making option C) x greater than negative one over six the correct answer choice.

The given inequality is:

(7 - 2x) / (-4) + 2 < -x

To solve for x, we need to isolate it on one side of the inequality. Let's simplify the equation step by step:

(7 - 2x) / (-4) + 2 < -x

7 - 2x + 8 < -4x (Added 2 to both sides)

15 - 2x < -4x

15 < 2x - 4x (Moved -2x to the right side)

15 < -2x

-15/2 > x

So the value of x in the inequality is x < -15/2. Therefore, the correct answer is option C) x greater than negative start fraction one over six end fraction.

Answer:

30 gallons

Step-by-step explanation:

let x represent the full container, then

[tex]\frac{1}{10}[/tex] x + 21 = [tex]\frac{4}{5}[/tex] x

Multiply through by 10 to clear the fractions

x + 210 = 8x ( subtract x from both sides )

210 = 7x ( divide both sides by 7 )

30 = x

The volume of the container is 30 gallons

Answer: the volume of the container is 30 gallons

Step-by-step explanation:

Let V represent the volume of the container, in gallons.

The initial volume of grains in the container is 1/0 × V = V/10

If 21 additional gallons of grain are added, the container is 4/5 full. This means that 21 gallons of grain + V/10 will occupy 4/5 of the volume of the container. Therefore

4/5 × V = 21 + V/10

4V/5 = 21 + V/10

4V/5 - V/10 = 21

7V/10 = 21

Multiplying the left hand side and right hand side of the equation by 10, it becomes

7V/10 × 5 = 21 × 10 = 210

7V = 210

V = 210/7 = 30

Answer:

Step-by-step explanation:

10) The opposite sides of a parallelogram are equal. It means that

a + 15 = 3a + 11

3a - a = 15 - 11

2a = 4

a = 4/2 = 2

Also,

3b + 5 = b + 11

3b - b = 11 - 5

2b = 4

b = 4/2 = 2

11) The opposite angles of a parallelogram are congruent and the adjacent angles are supplementary. This means that

2x + 11 + x - 5 = 180

3x + 6 = 180

3x = 180 - 6 = 174

x = 174/3 = 58

Therefore,

2x + 11 = 2×58 + 11 = 127 degrees

The opposite angles of a parallelogram are congruent, therefore,

2y = 127

y = 127/2 = 63.5

12) The diagonals of a parallelogram bisect each other. This means that each diagonal is divided equally at the midpoint. Therefore

3y - 5 = y + 5

3y - y = 5 + 5

2y = 10

y = 10/2 = 5

Also,

z + 9 = 2z + 7

2z - z = 9 - 7

z = 2

Answer:

Step-by-step explanation:

Perpendicular slopes are the opposite reciprocals of the slopes given.  Our slope in 8 is -2.  That means that the perpendicular slope is 1/2.  If the line goes through (2, -1), then

[tex]y-(-1)=\frac{1}{2}(x-2)[/tex] and

[tex]y+1=\frac{1}{2}x-1[/tex] and

[tex]y=\frac{1}{2}x-2[/tex]

9 is a tiny bit trickier because we don't have the slope, the x term, on the opposite side of the equals sign from the y.  Let's do that and then we can determine the slope of that given line.  Moving over the 3x and isolating the y:

y = -3x + 5

So the slope is -3.  That means that the perpendicular slope is 1/3.  If the line goes through (-9, 3), then

[tex]y-3=\frac{1}{3}(x-(-9))[/tex] and

[tex]y-3=\frac{1}{3}(x+9)[/tex] and

[tex]y-3=\frac{1}{3}x+3[/tex] so

[tex]y=\frac{1}{3}x+6[/tex]

Answer:

Step-by-step explanation:

8) y = -2x + 1 and the line passes through (2, - 1)

The equation of a straight line can be represented in the slope intercept form as

y = mx + c

Where

m = slope = (change in the value of y in the y axis) / (change in the value of x in the x axis)

The equation of the given line is

y= -2x + 1

Comparing with the slope intercept form, slope = - 2

If two line passing through the given point is perpendicular to the given line, it means its slope is the negative reciprocal of that of the given line. Therefore, the slope of the line passing through (2,-1) is 1/2

To determine the intercept, we would substitute m = 1/2, x = 2 and y = -1 into y = mx + c. It becomes

- 1 = 1/2 × 2 + c = 1 + c

c = - 1 - 1 = - 2

The equation becomes

y = x/2 - 2

9) 3x + y = 5 and the line passes through (-9, 3)

The equation of the given line is

3x + y = 5

y = -3x + 5

Comparing with the slope intercept form, slope = - 3

If two line passing through the given point is perpendicular to the given line, it means its slope is the negative reciprocal of that of the given line. Therefore, the slope of the line passing through (- 9, 3) is 1/3

To determine the intercept, we would substitute m = 1/3, x = -9 and y = 3 into y = mx + c. It becomes

3 = 1/3 × -9 + c = - 3 + c

c = 3 + 3 = 6

The equation becomes

y = x/3 + 6

Answer:

Step-by-step explanation:

When considering mortgage payments, homeowners insurance, property tax and maintenance costs over 30 years, the true cost of the $96,000 home is $287,068.80.

The true cost of a home not only includes the original purchase price but also takes into account annual homeowners insurance, property taxes, and maintenance costs. In this case, the purchase price is $96,000, homeowners insurance costs $1012 per year, property taxes are 1.1% of the home price each year, and annual home maintenance is 1% of the home price.

First, calculate the total mortgage payments made over 30 years. The monthly payment is $545.08, so the total mortgage payments are:

30 years * 12 months/year * $545.08/month = $196,228.80

Next, calculate the total cost of homeowners insurance over 30 years:

30 years * $1012/year = $30,360

Then, calculate the total property taxes over 30 years:

30 years * 1.1% of $96,000/year = $31,680

Lastly, calculate the total home maintenance over 30 years:

30 years * 1% of $96,000/year = $28,800

Adding all of these costs together gives the total cost of the home:

$196,228.80 + $30,360 + $31,680 + $28,800 = $287,068.80

So, the correct answer is option C: $287,068.80.

It takes 80 minutes to print 5200 copies.

Step-by-step explanation:

In 5 minutes the machine prints 325 copies and it can print at that steady state.

We have to find the number of copies it prints in  1 minute.

So ,number of copies in 1 minute = [tex]\frac{number of copies in 5 minute}{5}[/tex]

                                          = [tex]\frac{325}{5}[/tex]

Worth of computers sold = $1900

Commission amount = 0.02*1900 = $38

Total commission amount = 66+38 = $104

Lacy would earn a commission of $104.

For $x of phones, we will multiply the given amount with commission rate;

Commission amount of $x phones = 0.06*x = 0.06x

For $y computers;

Commission amount of $y computers = 0.02*y = 0.02y

Lacy would earn 0.06x dollars on phones sale and 0.02y dollars on computer sales.

XY = 17

Step-by-step explanation:

It is given that x is the mid-point of WY, so it divides WY in two equal parts

WX and XY so the sum of both lengths will constitute the length of WY

[tex]WY = WX+XY\\XY = WY - WX[/tex]

putting values

[tex]XY = 10x-26 -(3x-1)\\= 10x-26-3x+1\\= 7x-25[/tex]

As X is the mid-point,

[tex]WX = XY\\3x-1 = 7x-25\\3x-1-3x = 7x-25-3x\\-1 = 4x-25\\-1+25 = 4x-25+25\\24 = 4x[/tex]

Dividing both sides by 4

[tex]\frac{4x}{4} = \frac{24}{4}\\x = 6[/tex]

XY = 7x-25

[tex]=7(6) -25\\= 42-25\\=17[/tex]

So,

XY = 17

Verification:

WX = XY

[tex]3x-1 = 7x-25\\3(6)-1 = 7(6)-25\\18-1 = 42-25\\17 = 17[/tex]
