The amount of tip I would leave for the waiter is  $24.89

A tip is a form of payment that is given to someone who renders a service. The amount of tip that was given is a percentage of the total bill at the restaurant.

The value of the tip can be determined by multiplying the percentage of tip by the total bill at the restaurant

Value of the tip = percentage tip x total bill at the restaurant

20% x  $24.89

0.2 x  $24.89 = $4.98

Answer:

1 : 5

Step-by-step explanation:

The solutions to the quadratic equation x² + 5x + 3 = 0 are:

x = (-5 + √13) / 2

x = (-5 - √13) / 2

To solve the quadratic equation x² + 5x + 3 = 0, we can use the quadratic formula:

x = (-b ± √(b² - 4ac)) / (2a)

In this equation, a = 1, b = 5, and c = 3. Substituting these values into the quadratic formula, we get:

x = (-5 ± √(5² - 4×1×3)) / (2×1)

Simplifying further:

x = (-5 ± √(25 - 12)) / 2

x = (-5 ± √13) / 2

Therefore, the solutions to the quadratic equation x² + 5x + 3 = 0 are:

x = (-5 + √13) / 2

x = (-5 - √13) / 2

Answer:

  The product of an odd number of negative factors is negative.

Step-by-step explanation:

The factor -1 can be factored from any negative number. Then the product of some number of negative numbers is the product of that number of positive numbers and -1 raised to that power.

An even power of -1 is 1.

An odd power of -1 is -1. So, the product of an odd number of negative factors is negative.

This is helpful to remember when considering the solutions to polynomial inequalities. Once the factored form of the polynomial is found, the solution will depend on the signs of the factors. For example, consider ...

  (x +4)(x -2)(x -3) < 0

The zeros of these factors are -4, 2, 3. At each of these values of x, the sign of one of the factors will change. For x<-4, all three factors are negative, so the inequality is true. For -4<x<2, only two of the factors are negative, so the inequality is false. For 2<x<3, one of the factors is negative, so the inequality is again true. For 3<x, all factors are positive, so the inequality is false. Then the solution is (x < -4) ∪ (2 < x < 3).

See the graph for a plot of this polynomial and the solution to the inequality.

Answer:

B. Positive correlation

Step-by-step explanation:

Positive correlation is nothing but when the values of x increase, the corresponding y values are also increase.

When we look at the scatter plot, when x increase, the y also increase.

Therefore, it is a positive correlation.

Hope this will helpful.

To find angle PQR in a parallelogram, we can use the Exterior Angle Theorem. By subtracting the measures of the other two angles in triangle QRS from 180 degrees, we find that angle PQR is 70 degrees.

To find the measure of angle PQR, we can use the fact that opposite angles in a parallelogram are congruent. This means that angle PQR is equal to angle STQ. Since STQ is an exterior angle of triangle QRS, we can use the Exterior Angle Theorem to find its measure by subtracting the measures of the other two angles in the triangle from 180 degrees.

Given that angle QRS is 110 degrees, we can find angle STQ by subtracting the measures of angles QRS and QSR from 180 degrees:

angle STQ = 180 - (110 + 180) = -110 degrees

However, angles cannot have negative measures, so we need to find the equivalent positive measure. Adding 180 degrees to -110 degrees gives us angle STQ = 70 degrees. Therefore, angle PQR is also equal to 70 degrees.

On the second day, Andrea will still win by 0.026 seconds and the other girl will be at 99.75 meters on the track.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, Andrea and Sula ran a race on a track that was 100 meters long.

Let us assume that Andrea completed the 100m race in 10 secs.

∴  Andrea's speed is (100/10) = 10m/sec.

Also given that Sula was exactly 5 meters behind her.

∴ In 10 secs she completed 95 meters, and her speed is

= (95/10) = 9.5m/sec.

The next day they ran another race and Andrea agreed to start 5 meters behind the starting line and both the girls run at the same speed,

∴  Andrea has to run 105 meters, so she'll complete the race in

(105/10) secs.

= 10.5 secs.

Sula has to run only 100 meters, so the time needed for her to complete is,

= (100/9.5) secs.

= 10.526 seconds.

So, on the next day, Andrea will win again by (10.526 - 10.5) secs

= 0.26 secs.

∴ When the winner crosses the finish line the other girl will be,

(10.5×9.5) meters = 99.75 meters on the track.

The triangle is isosceles.

A triangle is a polygon that has three vertices on each of its three sides. The angle that is created within the triangle is 180 degrees. It indicates that the sum of a triangle's interior angles is 180 degrees. This is a polygon with the fewest sides. At the end of the day, a triangle is characterized as a three-sided two-layered figure whose inside points are equivalent to 180°.

Given a triangle let the triangle be ΔABC

given angles (4x + 8), (5x + 2) and (6x - 10)

let ∠A = (4x + 8), ∠B =  (5x + 2) and ∠C  = (6x - 10)

we know that sum of angle of triangle is 180⁰

∠A + ∠B + ∠C = 180

4x + 8 + 5x + 2 + 6x - 10 = 180

15x = 180

x = 180/15 = 12

∠A = 4x + 8 = 4(12) + 8 = 56⁰

∠B = 5x + 2 = 5(12) + 2 = 62⁰

∠C = 6x - 10 = 6(12) - 10 = 62⁰

since ∠B = ∠C

it is the property of an isosceles triangle, An isosceles triangle is a triangle with any two sides that are the same length and angles on opposite sides that are the same size.

Hence the Given triangle is isosceles.

Answer:  The correct option is (a) [tex]2x^2+3x-5.[/tex]

Step-by-step explanation:  We are given to find the quotient in the following division :

[tex]Q=\dfrac{2x^3-3x^2-14x+15}{x-3}.[/tex]

To find the quotient, first we will try to factorize the numerator and then we will try to divide by the denominator.

We have

[tex]Q\\\\\\=\dfrac{2x^3-3x^2-14x+15}{x-3}\\\\\\=\dfrac{2x(x-3)+3x(x-3)-5(x-3)}{x-3}\\\\\\=\dfrac{(x-3)(2x^2+3x-5)}{(x-3)}\\\\=2x^2+3x-5.[/tex]

Thus, the required coefficient is [tex]2x^2+3x-5.[/tex]

Option (a) is CORRECT.

The measure of angle m∠3 would be 60°.

The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.

Given;

g ∥ h, m∠1 = (4x + 36)°,

m∠2 = (3x – 3)°.

m∠2 = m∠3 ( alternate interoir angle)

we know that

m∠1 + m∠2 = 180

4x + 36 + 3x – 3 = 180

7x + 33 = 180

7x = 147

x = 21

Substituting

m∠2 = 3x – 3

m∠2 = 3(21) - 3

m∠2 = 63 - 3

m∠2= 60

Therefore, m∠3 = m∠2 = 60

Hence, The measure of angle m∠3 would be 60°.

Answer:

Step-by-step explanation:

We have been given an equation [tex]v=-1385n+18,790[/tex], which represents the value of a car. We are asked to find the n-intercept of our given equation.

We know that the n-intercept will be at [tex]v=0[/tex].

[tex]0=-1385n+18,790[/tex]

Subtracting 18,790 from both sides of our equation we will get,

[tex]0-18,790=-1385n+18,790-18,790[/tex]

[tex]-18,790=-1385n[/tex]

Now, we will divide both sides of our equation by [tex]-1385[/tex].

[tex]\frac{-18,790}{-1385}=\frac{-1385n}{-1385}[/tex]

[tex]13.566787=n[/tex]

[tex]n\approx 13.57[/tex]

C. His friend's house, grocery store, and his home.

Step-by-step explanation:

Triangle Proportionality Theorem-

If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.

So if the line joining the park, bus stop and friend's house, grocery store will be parallel, Stephen can use triangle proportionality theorem.

When two lines are crossed by another line i.e the transversal, the angles in matching corners are called corresponding angles. And when the corresponding angles are equal then the two lines are parallel.

The corresponding angle of the angle between the park, the bus stop, and his home is the angle between his friend's house, grocery store, and his home.

Therefore, he needs to measure that angle.

The number of  each type of bill or coin the wallet contains is:

It is given that:

A wallet holds $ 25 in total.

Also, the number of $ 1 bills,$ 5 bills and qaurters are present in equal number in the wallet.

Let the number of each coin or bill in the wallet be: x

Also, we know that:

1 quarter= 1/4 dollar

i.e.

1 quarter= 0.25 dollar

Hence, we get:

 x+5x+0.25x=25

i.e.

6.25 x=25

On dividing both side of the equation by 6.25 we get:

   x=25/6.25

i.e.

x=4

Hence, the number of each kind of coin or bill are: 4
