Can someone tell me what number on the number line is greater than -9 for an inequality?

The equation that represent the situation is 16.25 = 50 - 6.75x.

The number of sandwich bought by the customer is 5.

A roast beef sandwich costs $6.75. A customer buys multiple roast beef sandwiches.  Let x represent the number of roast beef sandwiches.

Then we will find the  how many sandwiches the customer buys when the amount Used for Payment is $50 and change received is $16.25.

Therefore, using equation,

16.25 = 50 - 6.75x

where

Therefore, let's find the number of sandwich bought using the equation.

16.25 = 50 - 6.75x

16.25 - 50 =  - 6.75x

-33.75 = -6.75x

divide both sides by -6.75

x = -33.75 / -6.75

x = 5

Hence,

number of roasted beef sandwich bought = 5

such pair of equation that have only one pair of solutions which satisfy both equation is linear equation

To classify a quadrilateral by its sides, we need to calculate the distance between each pair of its vertices.

The distance between Q and R is the square root of ((1-(-2))^2 + (5-(-1))^2) = square root of (3^2 + 6^2) = square root of (9+36) = square root of 45 = 6.7

The distance between R and T is the square root of ((-8-1)^2 + (-4-5)^2) = square root of (9+81) = square root of 90 = 9.5

The distance between Q and T is the square root of ((-8+2)^2 + (-4+1)^2) = square root of (10+5) = square root of 15 = 3.87

If the quadrilateral is a rectangle, two sides of it have to be equal, so in this case, AQRT is not a rectangle.

If the quadrilateral is a rhombus, all four sides have to be equal, so in this case, AQRT is not a rhombus.

If the quadrilateral is a square, all four sides have to be equal, so in this case, AQRT is not a square.

If the quadrilateral is a trapezoid, two adjacent sides are parallel, so in this case, AQRT is not a trapezoid.

If the quadrilateral is a parallelogram, two pairs of opposite sides are parallel, so in this case, AQRT is not a parallelogram.

If the quadrilateral is a kite, two pairs of sides have the same length, so in this case, AQRT is not a kite.

So the only possible classification is that AQRT is a general quadrilateral.

so we have:

QR = 6.7

RT = 9.5

QT = 3.87

Step-by-step explanation:

Here is the graph, I hope this helps, have a great school day! :D

Answer:

B

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

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

with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (0, - 3) ← 2 points on the line

m = [tex]\frac{-3-0}{0-(-1)}[/tex] = [tex]\frac{-3}{0+1}[/tex] = [tex]\frac{-3}{1}[/tex] = - 3

the line crosses the y- axis at (0, - 3 ) ⇒ c = - 3

y = - 3x - 3 ← equation of line

Answer: The measure of each interior angle of a regular octagon can be found using the formula:

(n-2) x 180 / n

Where n is the number of sides in the polygon.

For Octagon, n=8

So we can substitute 8 for n in the formula:

(8-2) x 180 / 8 = 6 x 180 / 8

Therefore, each interior angle of the base of Octagon Towers measures 135 degrees.

The correct first step in solving the inequality –4(2x – 1) > 5 – 3x is option A: Distribute –4 to get –8x + 4 > 5 – 3x.

This is because we are trying to solve for x, so we need to get x on one side of the inequality and all the other terms on the other side. In order to do this, we need to apply distributive property of multiplication over addition, which means we need to multiply the -4 with the 2x-1. By doing this we get -8x + 4 > 5 - 3x. This can help us to move forward in solving the inequality. This is the correct first step as it gets us closer to isolating the variable x on one side of the inequality.

After this step, we can further simplify the inequality by adding or subtracting similar terms to get the final solution.

It is important to remember that when solving inequalities we need to be careful with the signs, specially when dividing or multiplying by a negative number, as it might change the direction of the inequality.

Answer:One minute let me find a answer

Step-by-step explanation:

a) The percentage abundance Shows us the amount of the substance in the element

b) The relative atomic mass for the element X has been obtained as 122.5 amu

c) The Rutherford's model explained showed the movement of the electrons.

The isotopes of an elements are the atoms of the elements that have the same atomic number but do not have the same mass number. We know that the atoms of the isotopes of the element that we have are important as we try to determine the relative atomic mass of the element as we have the element X in this case.

Now we have that;

Relative atomic mass = Weighted average of all the isotopes

As such we have;

(121 * 0.432) + (123 * 0.531) + (129 * 0.0370)

52.27 + 65.31 + 4.773

Answer: 85 ÷ 5 = 17

Step-by-step explanation: We can simply find whatever division problem that has a quotient of 17 by multiplying 17 by something. So, I chose to do 17 * 5. That equals 85. Now to turn this into a division problem, we just take the product and divide it by a number other than 17 (5 in our case) so, it would look like 85 ÷ 5. That is 17. The way to check is by taking the 17 and multiplying it by the number in the middle (5). We get 85, making this statement true. I hope this helped!

Answer:

what is the question

Step-by-step explanation:

The following is a basic formula to find the scale factor of a dilated figure is:  :  Scale factor = Dimension of the new shape ÷ Dimension of the original shape.

Sizing Factor (Dilation) The image's size will depend on the scale factor, which is used to dilate a mathematical entity (compared to the original object). An expansion happens when the scaling factor's absolute value exceeds one.

Dilation is the process of increasing an object's size without altering its shape. Depending on the scale factor, the object's size may increase or shrink. A square of side 5 units can be widened to a square of side 15 units using dilation math, but the square's shape doesn't change.

In geometry, dilation math is used to enlarge and reduce two- or three-dimensional figures.

A scale factor is a numerical value that can be used to alter the size of any geometric figure or object in relation to its original size. It is the ratio of the original figure's and dilated figure's sizes.

You can use r or k to represent the scaling factor.

If the scale factor is more than 1 (k > 1), the image is expanded.

If the scale factor is less than 1 (0 k 1), the image is condensed.

If the scale factor is 1 (k = 1), the image doesn't change.

It should be noted that the scale factor's magnitude is taken into account and that it cannot be 0.

An object's size can change depending on the scale factor, either growing or shrinking. The following is a basic formula to determine a dilated figure's scale factor:

Another approach to express this formula that aids in determining the new shape's dimensions is as follows:

using Pythagoras' identity in the right triangle.

the square on the hypotenuse is equal to the sum of the squares on the other 2 legs.

let h represent the hypotenuse , then

h² = 3² + 3² = 9 + 9 = 18 ( take square root of both sides )

h = [tex]\sqrt{18}[/tex] = [tex]\sqrt{9(2)}[/tex] = [tex]\sqrt{9}[/tex] × [tex]\sqrt{2}[/tex] = 3[tex]\sqrt{2}[/tex] ← exact value

Exponential of 1 is equal to the number itself which means 1.

Exponent is usually described as the method of demonstrating large numbers in terms of powers. It means, exponent refers to the count, that how many times a number is multiplied to itself to calculate that exponent.

In accordance with the exponent rule, any number raised to power of 1 would always be equal to 1 that is because it doesn't matter how many times we multiply 1 to itself. It is going to yield 1. For example, multiplying 1 hundred times i.e. 1^100 also results in 1.

Answer: It would be 29.01

a) The compound interest rate is 75%

b) The simple interest rate is 12.5%

What is the interest?

We know that the interest is the money that accrues to an investment that have been made. We know that we can be able to determine the simple interest by the use of the formula.

A = P(1 + r/n)^nt

A = amount

P = principal

r = rate

n = Number of times compounded

Then we have;

2(1000) = 1000(1 + r)^8

Where n = 1

2 =  (1 + r)^8

0.693 = 8 ln(1 + r)

e^0.693/8= (1 + r)

r = 1 - e^0.693/8

r = 0.75 or 75%

For the simple interest rate;

I = PRT/100

I = A - P

I = 2000 - 1000 = 1000

1000 = 1000 * R * 8/100

R = 1 * 100/8

R = 12.5%
