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.

% increase

[tex]= {(165 - 115) / 115 } × 100 = 43.48%. ≈ 44%[/tex]

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

System Linear equation has no solution , because it is paralell lines but no intersection.

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,

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

=> 1=3

Hence the given system equation has no solution , because it is paralell lines but no intersection.

the bisectors of two supplementary angles are perpendicular to each other is proved along with the given diagram.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

Here, we have,

Answer:

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.

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

Given points:

Substitute the given (x, y) points into the exponential function formula to create two equations:

[tex]\implies 20=ab^2[/tex]

[tex]\implies 640=ab^7[/tex]

Divide the second equation by the first equation to eliminate a:

[tex]\implies \dfrac{640}{20}=\dfrac{ab^7}{ab^2}[/tex]

[tex]\implies 32=\dfrac{b^7}{b^2}[/tex]

Solve for b:

[tex]\implies 32=b^7 \cdot b^{-2}[/tex]

[tex]\implies 32=b^{7-2}[/tex]

[tex]\implies 32=b^5[/tex]

[tex]\implies b=2[/tex]

Substitute the found value of b into one of the equations and solve for a:

[tex]\implies 20=a \cdot 2^2[/tex]

The statement that is true about the ratios comparing the width and length of each painting is:

The paintings' width to length ratios are equal because the ratio 4 to 6 is equal to the ratio 2 to 3.

A ratio is a fraction which compares the values of two numbers. Such that they can be expressed as a ratio of one to the other. Example is the ratio of a to b which can be expressed as; a:b or a/ b.

From the first dimension of the canvas size, we have;

length = 6 feet

width = 4 feet

So that,

the ratio comparing the width and length = 4/ 6

                                                       = 0.6667

From the second dimensions of the canvas size, we have;

The Fourier series coefficients for T-2 and A-4 are Ao = 2, B(n-odd) = 0, and B(n-even) = -(4/nπ). The Fourier series for the function is then given by:Y(t) = A0 + ΣB(n)cos(nπt/T) + ΣB(n)

The Fourier series coefficients are used to determine the Fourier series of a given function. The Fourier series is an infinite series of sines and cosines which, when summed, gives an approximation of the original function.

The coefficients are determined by integrating the function over a period and solving for the coefficient of each term.

The coefficients for the function T-2 and A-4 are determined by first calculating the period of the function. The period of the function is T=4. The coefficients are then calculated by integrating the function from 0 to T and solving for each coefficient. The coefficients for T-2 and A-4 are then calculated as follows:

A0= 2

B(n-odd) = 0

B(n-even) = -(4/nπ)

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 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 )
