Step-by-step explanation:

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

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

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].

True about translations is they can help you see if two figures are congruent

What are translations?

In mathematics, a translation is an up, down, left, or right movement of a shape. Because the translated shapes appear to be exactly the same size as the original ones, they are consistent with one another. Just one or more directions have been altered. There is no change in the shape because it is simply being moved from one location to another.

Each point in a figure is moved the same distance in the same direction using a type of transformation known as translation.

Hence, they can help you see if two figures are congruent.

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 measures of the numbered angles in the rhombus ABCD if m∠ABC = 49° are m∠1 = 24.5°, m∠2 = 90°, m∠3 = 24.5° and m∠4 = 65.5°.

We are given:

A rhombus ABCD and m∠ABC = 49°.

The diagonal of the rhombus divides the angles into 2 equal parts. Therefore,

m∠1 = m∠ABC / 2 = 49 / 2 = 24.5°

The diagonal AC is perpendicular to the diagonal DB.

And we know that diagonals bisect each at right angles.

So, m∠2 = 90°.

Opposite angles of the rhombus are equal.

Therefore,

∠B = ∠D

multiply both sides by 1/2, we will get;

1/2 ∠B = 1/2 ∠D

m∠1 = m∠3 = 24.5°

Sum of angles in a quadrilateral = 360°

360 -  98 = 262°

∠A = ∠C = 262 / 2 = 131

Therefore,

m∠4 = 1 / 2 ∠C

m∠4 = 1 /2 * 131

m∠4 = 65.5°

Thus, the measures of the numbered angles in the rhombus ABCD if m∠ABC = 49° are m∠1 = 24.5°, m∠2 = 90°, m∠3 = 24.5° and m∠4 = 65.5°.

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
