Answer:
Step-by-step explanation:
11 [tex]\frac{1}{2}[/tex] + [tex]\frac{5}{8}[/tex]
make all the fractions an improper fraction
(11×2)+1/2 = 23/2
(3x5)+5/8 = 29/8
you need to make sure both fractions have a common denominator
to make 23/2 common with 5/8 you multiply 23/2 by 4/4
wich will make 92/8
continiue with the question
92/8 + 29/8= 121/8
simplify by dividing by 8 to get a mixed number
15 1/8

The vivandière sold viands and sandwiches. If she sold 300 total and 50 more viands than sandwiches, how many of each did she sell?
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".
How to construct equation?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. This method, as the name suggests, involves substituting the value of a variable from one equation into the other equation ".

The value of y varies directly with x and inversely with the square of z. What equation models this combined variation?
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].

Which company shows a greater/higher rate of change?
Water’s EdgeRafts
Ryan’s Rafts
Whoever answers correctly will get Brainliest!!
The rate of change of the company Water's Edge rafts is greater than Ryan’s Rafts.
What is the slope?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.

Casho is trying to find the height of a radio antenna on the roof of a local
building. She stands at a horizontal distance of 26 meters from the building.
The angle of elevation from her eyes to the roof (point A) is 32°, and the
angle of elevation from her eyes to the top of the antenna (point B) is 36°. If
her eyes are 1.75 meters from the ground, find the height of the antenna (the
distance from point A to point B). Round your answer to the nearest meter if
necessary.
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

∡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
[tex]\begin{gathered} \measuredangle BDC=\frac{1}{2}BC \\ \\ 29=\frac{1}{2}BC \\ \\ 2(29)=BC \\ \\ 58=BC \end{gathered}[/tex]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
