1. Sally wants to buy a pair of shoes for $12. 50 and a shirt for $23. 50. If 50 points the sales tax is 8. 25%, what will be the amount of the sales tax Sally's purchase?​

Answer:

7/12 of a mile

3/4 = 18/24

1/6 = 4/24

18-4 = 14

14/24 = 7/12

Step-by-step explanation:

The points shown on the graph are (-1,2) and (1,-2).

d = sqrt{-2-2)^2 + (1-(-1))^2}

d = sqrt{(-4)^2 + (1+1)^2}

d = sqrt{16 + 4}

d = sqrt{20}

d = 4•sqrt{5}

d is about 8.94427191.

Rounded to the nearest tenth, we get d = 8.9.

From the question, we are informed that Shelly has a beaker which contains 5 2/3 fluid ounces of water and that she pours out 3 1/3 fluid ounces of water. The expression that an be used to find the number of fluid ounces of water which remain in the beaker goes thus:

Let's represent the remaining water in the beaker as x.

Since 3 1/3 fluid ounces of water has been poured our from 5 2/3 fluid ounces of water. The expression will be:

x = 5 2/3 - 3 1/3

Answer:

A

Step-by-step explanation:

The total amount he would have at 69 is $343,347.81.

The formula that can be used to determine the future value of the deferred annuity is:

Future value = annuity factor x monthly deposit

Annuity factor = {[(1+r)^n] - 1} / r

Where:

Amount he would save every 6 months:

Future value : 900 x {[(1.0275^90) - 1] / 0.275}= $343,347.81

Answer:

18. Two real solutions

Step-by-step explanation:

Q 18

For a quadratic equation in standard form i.e. ax² + bx + c = 0

the discriminant is given by b² - 4ac

If the discriminant is 0, there is one real solution

If the discriminant is positive, there are two real solutions

If the discriminant is negative , there no real solutions

The given equation is:
x² - 8x = -14

Adding 14 to both sides

=> x² - 8x + 14 = 0

Comparing to the standard equation, we see

a = 1, b = -8, c = 14

Discriminant b² - 4ac = (-8)² - 4 x 1 x 14
= 64 - 56

= 10

Since discriminant is positive, there are two real solutions

Step-by-step explanation:

You already know that TS = AB and TU = BC because it shows that in the images using the tick marks. SSS Triangle Congruence Postulate is when two triangles are congruent to each other because all the corresponding side lengths are equal to each other. So we already have two side lengths that are equal to each other, and, in order for SSS to be true, we need all 3 side lengths to be equal to each other. The only two side lengths not equal to each other yet are US and CA so if those were to be equal to each other, all corresponding side lengths would be equal to each other.

The number 3.23×10^6, expressed in standard decimal notation, is 3,230,000. In scientific notation, a number is expressed as the product of a coefficient and a power of 10.

In this case, the coefficient is 3.23, and the power of 10 is 6. To convert this number into standard decimal notation, we need to multiply the coefficient by the corresponding power of 10. The power of 10, in this case, is 10^6, which means 10 raised to the power of 6. This is equivalent to 1 followed by six zeros: 1,000,000. To obtain the standard decimal notation, we multiply the coefficient, 3.23, by 1,000,000.

Calculating the multiplication, we have:

3.23 × 1,000,000 = 3,230,000.

Hence, the number 3.23×10^6, expressed in standard decimal notation, is 3,230,000. This means that the number is equal to 3.23 million.

Given:

The  monthly phone cost C can be represented by this equation:

\(C=12+a\cdot m\)

where, a is the additional  charge per minute, and m is the number of minutes used.

To find:

The equation can be used to find the number of minutes a customer used if we know and a and C.

Solution:

We have,

\(C=12+a\cdot m\)

We need to isolate m on one side.

Subtract 12 from both sides.

\(C-12=a\cdot m\)

Divide both sides by a.

\(\dfrac{C-12}{a}=\dfrac{a\cdot m}{a}\)

\(\dfrac{C-12}{a}=m\)

\(m=\dfrac{C-12}{a}\)

The options are not in proper format.

Therefore, the required equation is \(m=\dfrac{C-12}{a}\).

The solutions of the given equations are given by equating the

variables to gives;

First part;

The given functions are;

y = -3·x² + 24·x + 3, and y = -4·x² + 25·x + 15

When the balloons collided, we have;

The height are equal, which gives;

y = y

-3·x² + 24·x + 3 = -4·x² + 25·x + 15

-3·x² + 24·x + 3 - (-4·x² + 25·x + 15) = x² - x - 12 = 0

Which gives;

x² - x - 12 = (x - 4) × (x + 3) = 0

x = 4, and x = -3

The time at which the balloon collide at the highest point is therefore;

Second part;

The given system of equations are;

x - y = 6

y = x² - 6

y = x - 6

Which gives;

x - 6 = x² - 6

x = x²

Which gives;

x = 0 or x = 1

Similarly, we have;

x = y + 6

Which gives;

y = (y + 6)² - 6

y² + 11·y + 30 = 0

(y + 5)·(y + 6) = 0

Which gives;

y = -5, or y = -6

When y = -5, we have; x = -5 + 6 = 1

The solution are therefore;

Third part;

The equations are; y = x + 7 and y = x² - 3·x + 7

At the solution, the u-values are equal, which gives;

y = y

x + 7 = x² - 3·x + 7

x² - 3·x + 7 - (x + 7) = 0

x² - 4·x = 0

x·(x - 4) = 0

x = 4, or x = 0

When x = 4, y = 4 + 7 = 11

When x = 0, y = 0 + 7 = 7

The solutions are located at points;

Fourth part;

Given that the point of intersection of the line and the quadratic function

is the point (2, 0), we have;

On the linear function, when y = 0, x = 2

The possible linear function functions is therefore;

x + y = 2

From the quadratic function that accompanies the above linear function, we have;

y = x² + 3·x + 2

When x = 0, y = 0² + 3×0 + 2 = 2

Therefore;

The duration of shoot would be 2 hours and Either stylist would cost $282 if the shoot lasted 2 hours.

A fashion photographer needs to hire a stylist to prepare his models.

Let the number of hours stylist take = x

Jayla charges $156 for showing up, plus $63 per hour. So, this can be mathematically written as ,

156 + 63x                                                  equation 1

Sally charges $158 plus $62 per hour.  So, this can be mathematically written as ,

158 + 62x                                                  equation 2

As per the question, the expected duration of his photo shoot, either stylist would cost him the same amount. So we can equate equation 1 and equation 2. On equating equation 1 and equation 2 , we will get

156 + 63x  = 158 + 62x

⇒  x = 2

So, the duration would be 2 hours.

Jayla cost = Sally cost = 156 + 63x  = 156 + (63 × 2) = 282

Either stylist would cost $282 if the shoot lasted 2 hours.

Answer:

Step-by-step explanation:

Step-by-step explanation:

-3(2 - b) < 10 - 3(b - 6)

-6 - 3b < 10 - 3b + 18

-6 < 28

Hence the inequality is true for any real values of b.

The solution to the inequality is:

b is less than 17/3.

Let's solve the inequality step by step:

-3(2 - b) < 10 - 3(b - 6)

First, simplify both sides of the inequality:

-6 + 3b < 10 - 3b + 18

Combine like terms:

3b - 6 < 28 - 3b

Next, add 3b to both sides:

6b - 6 < 28

Now, add 6 to both sides:

6b < 34

Finally, divide both sides by 6:

b < 34/6

Simplifying the right side:

b < 17/3

Therefore, the solution to the inequality is:

b is less than 17/3.

The graph of Stewart's assignment added as an attachment

From the question, we have the following parameters that can be used in our computation:

Number of assignments = 36

Rate of assignment per day = 4

This means that the equation of the scenario is

Number of assignments remaining = Initial number of assignments - Rate of assignment per day * Number of days

Represent the number of assignments remaining with y and the number of days with x

So, we have the following representation

y = Initial number of assignments - Rate of assignment per day * x

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

y = 36 - 4 * x

Evaluate the products

y = 36 - 4x

So, the equation is y = 36 - 4x and the graph is added as an attachment

Answer:

hope this helps you dear

The term is called an identity element. In multiplication, the identity element is one because any number multiplied by one results in the same number. In addition, the identity element is zero because any number added to zero results in the same number.

The term in mathematics for the operation or number that leaves others unchanged when combined with them is called the identity element.

It is also known by the name of neutral element.

In multiplication, the identity element is one (1) because when you multiply a number by one the result remains the same as the original number. For any number a,

a1=1a=a.

While in addition, the identity element is zero (0) because when you add zero to a number, the result remains the same as the original number. For any number a,

a+0=0+a=a.

There is no identity element for subtraction, and division only has an identity element for certain sets.
