Answer:

B $3.00

Step-by-step explanation:

We need to estimate a little.  We are trying to find the slope.  We need two points.  The one point that is clear is (4,15)  I would estimate the other points to be (0,3)  The slope is the change in y over the change in x

the y values from the two points are 15 and 3.  The x values are 4 and 0

Option B is correct answer, 79 pounds is equal to 35.866 kilograms.

What is unit conversion?

A unit conversion is used to express the same property in a different unit of measurement. Minutes can be used to measure time instead of hours, and feet, kilometers, or any other measurement can be used to measure distance in place of miles. Measurements are typically provided in one system of measurement, such as feet, but are necessary in a different system, such as chains. A mathematical formula known as a conversion factor enables an equivalent exchange of feet for chains.

As it is given in the question,

1 Pound =  0.454 Kilograms,

So, In order to convert 79 pounds into kilograms we have to multiply 0.454 by 79.

79 pounds = 79(0.454) kilograms

79 pounds = 35.866 kilograms

Therefore, option B is correct answer.

For the parabola y = 2x² + 3x + 1,

a. i.  The x-intercepts are x = -1/2 and x = -1

a. ii. The y-intercept is y = 1

b. i. The line of symmetry is at x = -3/4

b. ii. The equation of the line of symmetry is x = -3/4

c.  The vertex is at (-3/4, -1/8)

A parabola is part of a conic section which is a curve.

Given the parabola y = 2x² + 3x + 1, we find the x- intercept when y = 0.

So, y = 2x² + 3x + 1

2x² + 3x + 1 = 0

2x² + 2x + x + 1 = 0

Factorizing, we have

2x(x + 1) + (x + 1) = 0

(2x + 1)(x + 1) = 0

2x + 1 = 0 or x + 1 = 0

2x = -1 or x = -1

x = -1/2 or x = -1

So, the x-intercepts are x = -1/2 and x = -1

Given the parabola y = 2x² + 3x + 1, we find the y- intercept when x = 0.

So, y = 2x² + 3x + 1

So, y = 2(0)² + 3(0) + 1

y = 0 + 0 + 1

y = 1

So, the y-intercept is y = 1

The line of symmetry passes through the vertex of the parabola where dy/dx = 0.

So, y = 2x² + 3x + 1

dy/dx = d(2x² + 3x + 1)/dx

= d(2x²)/dx + d3x/dx + d1/dx

= 4x + 3 + 0

= 4x + 3

So, when dy/dx = 0,we have

4x + 3 = 0

4x = -3

x = -3/4

So, the line of symmetry is at x = -3/4

The equation of the line of symmetry is x = -3/4

Since the vertex of the parabola is a t x = -3/4, substituting this into the equation, we have

y = 2x² + 3x + 1

y = 2(-3/4)² + 3(-3/4) + 1

y = 2(9/16) - 9/4 + 1

y = 9/8 - 9/4 + 1

y = (9 - 18 + 8)/8

y = (17 - 18)/8

y = -1/8

So, the vertex is at (-3/4, -1/8)

The solutions of system of equation are x = 1 and y =-4.

One or many equation having same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given that the system of equation;

-5x-4y = -17 , (equation 1)

-3x-y =  1, (equation 2)

First step is to write both equation in the standard form, both of these above equations are in standard form.

Now we will make the coefficients of variable y opposite, for that we multiply -4 to the equation 2.

12x+4y = -4

Now, in equation 2 coefficients of variable y are opposite.

Next step is combining the both of the equation;

-5x + 12x = -17 -4

7x = -21

x = -3

Substitute the value of x into equation 2,

-3x-y = 1

-3 (-3) -y = 1

In mathematics, a fraction is used to represent a piece or part of a whole. It symbolizes the equal pieces of the whole. A fraction is made up of two parts: the numerator and the denominator. The top number is known as the numerator, while the bottom number is known as the denominator. A common fraction is a numeric representation of a rational integer. The same number can be expressed as a decimal, a percentage, or with a negative exponent. Fractions indicate pieces of a whole or group of items. A fraction is made up of two components. The number at the top of the line is referred to as the numerator. It specifies the number of equal sections of the whole or collection that are taken. The figure below the line is denominator.

Step-by-step explanation:

The statements that are always true regarding the diagram of interior and exterior angles of a triangle include the following:

C. m∠5 + m∠6 =180°.

D. m∠2 + m∠3 = m∠6.

E. m∠2 + m∠3 + m∠5 = 180°.

In Geometry, the Linear Pair Postulate states that the measure of two (2) angles would add up to 180° provided that they both form a linear pair. This ultimately implies that, the measure of the sum of two (2) adjacent angles would be equal to 180º when two (2) parallel lines are cut through by a transversal:

m∠5 + m∠6 =180°.

In Mathematics, the exterior angle property can be defined as a theorem which states that the measure of an exterior angle in a triangle is equal in magnitude to the sum of the measures of the two remote or opposite interior angles of that triangle:

m∠2 + m∠3 = m∠6.

Additionally, the sum of all the angles that are formed by a triangle is equal to 180º and this is given by:

m∠2 + m∠3 + m∠5 = 180°,

The unit rate for each size to the nearest hundredth of a dollar is Size A = $0.484, Size B = $0.393, Size C = $0.343 and Size D =$0.359.

What is unit rate?

Unit rate is a rate in which the second term of a ratio is one. Unit rate is a way to compare different quantities in which the second term is a constant of one. Unit rate is determined by dividing one quantity by another, with the second quantity always being one. Unit rate can be used to compare different items, such as prices when shopping, or to measure the speed of an object over a given period of time. Unit rate is often expressed as a whole number or a fraction.

Unit rate for Size A = $0.48, Size B = $0.39, Size C = $0.34 and
Size D =$0.36.
Given:
Size A The 7 1/5 ounce can cost $3.49.
Size B The 16 1/2 ounce can cost $6.49.
Size C The 24 3/4 ounce can cost $8.49.
Size D The 30 2/3 ounce can cost $10.99.
To find the unit rate for each, we take the total price and divide by the total ounce,
Size A = [tex]\frac{3.49}{\frac{36}{5} } =0.484[/tex]
Size B = [tex]\frac{6.49}{\frac{33}{2} } =0.393[/tex]

The percentage decrease from the first number to the second of 150 to 100 is 33.33% and for 300 to 250 is 16.67%.

A percentage, often known as percent, is a division by 100. Percentage, which means "per 100," designates a portion of a total sum. 45 out of 100 is represented by 45%, for instance. Finding the percentage of a whole in terms of 100 is what percentage calculation is. Both manual calculation and the use of internet calculators are options.

Given:

Initial number  = 150

Final number = 100

Calculate the percentage decrease by the formula given below,

[tex]Percentage\ decrease = (Initial \ number -Final\ number )Initial\ number \times 100[/tex]

Percentage decrease = (150 - 100) / 150 × 100

Percentage decrease = 50 / 150 × 100

Percentage decrease = 33.33%

Similarly, for 300 to 250

Percentage decrease = (300 - 250) / 300 × 100

Percentage decrease = 50 / 300 × 100 = 16.67%

Therefore, the percentage decrease from the first number to the second of 150 to 100 is 33.33% and for 300 to 250 is 16.67%.

First, let's find the sum of the digits in the first 99 numbers of the sequence. Each number in the sequence has two digits, so the sum of the digits in the first 99 numbers is 99 * 18 = 1872.

Next, we need to add in the digits in the number 100. The sum of the digits in 100 is 1 + 0 + 0 = 1.

Answer: children = 258, adults = 269

Step-by-step explanation:

let x = number of children

let y = number of adults

x + y = 527

solve for x in terms of y:

x = 527 - y

$1.5x + $2.5y = $1059.50

substitute in x = 527 - y

1.5(527 - y) + 2.5y = 1059.50

Now you can solve for y:

790.50 - 1.5y + 2.5y = 1059.50

y = 1059.50 - 790.5 = 269

Now solve for x:

x + 269 = 527

x = 527 - 269 = 258

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

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
