Mark buys $45 worth of office supplies. He uses a 15% off coupon. What will be the new price?

Answer:

Brand Z

Step-by-step explanation:

Set up all of them up as a fraction x/y where x is the fluid ounces and y is the cost.

Next, find the values of all the fractions and note them down.

Brand Z had the highest cost per fluid ounce of 2, and therefore is the correct answer.

Answer:

Brand w.

Step-by-step explanation:

First thing you want to do is divide your fluid ounces by your given cost. Which ever is greatest is your answer.

Brand w: 20/12.00 = 1.66

Brand x: 15/11.25 = 1.33

Brand y: 10/6.50 = 1.53

Brand z: 5/2.50 = 2.00

Brand w has the greastest price per fluid ounce compared to the rest of the brands.

One solution of the following system is:

A. (–6, 0)

The above mathematical expression requires that we use the substitution formula to obtain the correct value.

2y - 2x = 12     ... 1

x² + y² = 36     ... 2

For equation 1

2y = 12 + 2x

          2

y = 6 + x           ... 3

Now we substitute equation 3 in equation 2

x² + (6 + x)² = 36

= x² + 36 + 12x + x² = 36

2x² + 12x = 36 -36

2x² + 12x = 0

2x (x + 6) = 0

x = 0, -6

When we substitute x for 0 in the third equation, we will have

y = 6 + 0 = 6

If we substitute x to be -6 in the third equation, we will arrive at

y = 0.

Therefore, the two solutions that can be obtained are (0,6) and (-6,0) as seen in the first option.

To the nearest percentage point, Lupita's retirement funds increased by 44% from June to July.

A percentage is a term used in mathematics to describe a value or ratio that may be expressed as a fraction of 100. If we need to calculate a percentage of a number, we should first divide it by 100 before multiplying it by the remainder. Consequently, the percentage refers to a portion per hundred.

Given that Lupita had $115 in her bank account at the beginning of June

The amount Lupita had set aside climbed to $165 in July.

We are expected to calculate the percentage growth in money.

Answer:

are the capital letter formed by three line segments.

The point on the graph is given by the coordinate Q ( 4 , 4 )

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be represented as P

The coordinates of point P = P ( 12 , 11 )

Now , the point P movers 8 units left

So , the new coordinates of the position is ( 12 - 8 , 11 )

The new coordinates is ( 4 , 11 )

And , the it moves 7 units down ,

So , the coordinates of the point Q be Q ( 4 , 11 - 7 )

On simplifying , we get

The coordinates of point Q = Q ( 4 , 4 )

Hence , the coordinate is Q ( 4 , 4 )

The sum of the interior angles of a decagon is 1440 degrees.

The inner angles of a normal decagon are equal. Every interior angle in a normal decagon is 144° in length because 1440°/10 = 144°. Additionally, each external angle measures 36°.

A decagon is a ten-sided polygon, or ten-gon, in geometry. A basic decagon's inner angles add up to 1440°, and its external angles add up to 360°.

A decagon is a polygon with ten sides, ten internal angles, and ten vertices, or points where the sides meet. There are 10 equal-length sides and 10 equal-sized interior angles in a normal decagon. The sum of all the angles, each of which is 144°, is 1,440°.

A decagon is a polygon having 10 sides.

The sum of interior angles of a polygon having 'n' sides is (2n- 4) × 90°.

sum of interior angles of a decagon= (204) × 90°

What is system linear equation?

An equation for a line is known as a linear equation. alternatively, y + 0.5x 3.5 = 0 and others. (Note that each linear equation is the same.) When multiple linear equations interact, we get a system of linear equations.

Here the given system linear equations,

[tex]3y=\frac{3}{2}x+6[/tex] -------> 1    and [tex]\frac{1}{2}y-\frac{1}{4}x=3[/tex] --------> 2

Divide by 3  of equation 1 on both sides then,

[tex]y=\frac{1}{2}x+2[/tex]  -----------> 3

Now put 3 into 2 then,

To express the deaths per capita as a decimal, we can divide the number of new construction accidents (deaths) by the population:

4172/11300000 = 0.00037

Rounded to 6 decimal places, the deaths per capita as a decimal is 0.00037

To express the deaths per capita in scientific notation, we can use the decimal value found above and convert it to scientific notation:

3.7 x 10^-4

To express the deaths per capita as a per 100,000 value, we can multiply the decimal value by 100,000:

0.00037 * 100,000 = 37

So the deaths per capita are 37 deaths per 100,000 people.

The greatest possible error of 4700 is equal to 2,350.

In Mathematics, precision can be defined as a quality which is independent of accuracy because it only describes how close together are numerical values that are obtained in a series of measurements.

In Mathematics, the greatest possible error (GPE) of a measurement can be defined as one-half of the value of a given smallest measuring unit, or one-half of a given precision.

This ultimately implies that, the greatest possible error (GPE) of a measurement can calculated by dividing the precision by two and this is represented by this mathematical expression;

Greatest possible error (GPE) = precision/2

Greatest possible error (GPE) = 4700/2

Greatest possible error (GPE) = 2,350.
