What is a number that is both a square number and a multiple of 9.

Answer:

if the egg was the same size then that must mean the eggs had different reactions than each other.

Step-by-step explanation:

To find the price per ounce for each grocery store we have to divide the price by the size of the bottle:

Hawkin's Grocery:

$0.25 per ounce

MItchell's Store:

$0.32 per ounce

Selena's Market:

$0.30 per ounce

Teresa's Store:

$0.20 per ounce

We can see that Teresa's Store has the lowest price per ounce

The equation is modelled as [tex]y\ = \frac{kx}{z^2}[/tex].

Given,

y varies directly with x

y varies inversely with square of z

According to given data the equation can be modelled as follows:

y varies directly with x, it can be written as [tex]y \ \alpha \ x[/tex]

and also y varies inversely with square of z, it can be written as [tex]y\ \alpha \ \frac{1}{z^2}[/tex]

Combining both, then we get,

[tex]y\ \alpha \ \frac{x}{z^2}\\\\y\ = \frac{kx}{z^2}[/tex]

Where, k is proportionality constant.

Thus, the combined equation is modelled as [tex]y\ = \frac{kx}{z^2}[/tex].

Multiplication:

Finding the product of two or more numbers in mathematics is done by multiplying the numbers. It is one of the fundamental operations in mathematics that we perform on a daily basis. Multiplication tables are the main use that is obvious. In mathematics, the repeated addition of one number in relation to another is represented by the multiplication of two numbers. These figures can be fractions, integers, whole numbers, natural numbers, etc. When m is multiplied by n, either m is added to itself 'n' times or the other way around.

Step-by-step explanation:

Distance from point A to point B is approx. 3m

What is the difference between Distance and Displacement?

While distance and displacement appear to signify the same thing, they actually have very different definitions and meanings.

A scalar quantity known as distance measures "how much ground an object has traversed" while moving.

An object's total change in position is referred to as displacement, a vector variable that measures "how far out of place an object is."

Distance is the sum of an object's movements, regardless of direction. Regardless of an object's starting or ending position, distance can be defined as the amount of ground it has covered.

The term "displacement" refers to a shift in an object's position. It is a vector quantity with a magnitude and direction. The symbol for it is an arrow pointing from the initial location to the ending place. For instance, if an object shifts from location A to position B, its position changes. Displacement is the term used to describe this shift in an object's position.

∠BCD = 36°

∠ACD = 32°

CD= 26m

tan∠BCD=0.726

tan∠ACD=0.624

since,

BD=CD x tan∠BCD

AD=CD x tan∠ACD

thus,

AB = BD-AD

= CD x tan∠BCD - CD x tan∠ACD

= CD x [0.726 - 0.624]

= 2.652

= approx 3 m

Answer:

∡BCA = 29

∡BOC = 58

Explanation:

The angles BDC and BAC form the same arc on the circle, the arc BC. Then, these angles have the same measure, so

∡BCA = ∡BDC

∡BCA = 29

Then, we can use the inscribed angle theorem to find the arc BC as follows

Therefore, arc BC has a measure of 58 degrees, which means that ∡BOC is equal to

∡BOC = Arc BC

∡BOC = 58

So, the answers are

∡BCA = 29

∡BOC = 58

The line y = 1 is a horizontal line and thus is a line that is parallel to the x-axis.

If we reflect about a line that is parallel to the x-axis, then the x-coordinate of the point (that is reflected) will remain the same, thus the image of (-1, 5) has x-coordinate -1 and thus the point is of the form (-1, b).

The point (-1, 5) is 4 units from the line y = 1 (because the difference between y = 5 and y = 1 is 4).

The reflected point has to be the same distance from the line y = 1 as the original point

She sold 125 sandwiches and 175 viands as per the equation using substitution method as the definition of substitution method says, "The algebraic approach to solving simultaneous linear equations is known as substitution method. The value of one variable from one equation is substituted in the other equation in this method, as the name implies".

A mathematical formula is an equation that uses algebraic operations like add, subtract, multiply, divide, raise to a power, take the natural logarithm, take the cosine, or some combination of operations to express one variable as a combination of other variable(s). One-step equations can be solved in four different ways: by adding, subtracting, multiplying, and dividing. In an equation, both sides will remain equal if we add the same amount to each side. The "scale" (or equation) must ALWAYS be balanced when solving math equations so that both sides are ALWAYS equal.

Here,

Let x be the sandwiches she sold and y be the viands she sold.

x+y=300

y=50+x

x+50+x=300

2x+50=300

2x=250

x=125

y=50+125

y=175

In accordance with the equation and applying the substitution method, she sold 125 sandwiches and 175 appetizers "The substitution method is an algebraic strategy for resolving simultaneous linear equations.

The rate of change of the company Water's Edge rafts is greater than Ryan’s Rafts.

The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.

From the graph, the two points are taken as (0, 0) and (1, 6). Then the slope of the Water's edge rafts will be given as,

⇒ (6 - 0) / (1 - 0)

⇒ $6 per hour

From the table, the two points are taken as (1, 15) and (5, 24). Then the slope of Ryan's rafts will be given as,

⇒ (24 - 15) / (5 - 1)

⇒ 9 / 4

⇒ $2.25 per hour
