Dominic is on the 8.75 mile of the bike path

From the question, the given parameters are:

The above parameters implies that

Dominic's position = 70% of the total distance

Represent the total distance with x

So, we have the following representation

Dominic's position = 70% * x

Where

x = 12.5

So, we have

Dominic's position = 70% * 12.5

Evaluate the products

Dominic's position = 8,75

The number of ride tickets that were sold are 8 and the number of food tickets that were sold  are 24  .

In the question ,

it is given that

total number of tickets bought by the family at carnival = 32 tickets

total amount spent by the family of tickets = $90

let the number of ride tickets be [tex]=[/tex] x

let the number of food tickets be [tex]=[/tex] y

So , x + y = 32

x = 32 - y

cost of 1 ride ticket = $1.50

cost of 1 food ticket = $3.25

So the total cost is 1.25x + 3.25y = 90

Substituting x = 32 - y in the equation 1.5x + 3.25y = 90 ,

we get ,

1.5(32 - y) + 3.25y = 90

48 - 1.50y + 3.25y = 90

1.75y = 90 - 48

1.75y = 42

y = 24

So , x = 32 - 24 = 8

Therefore , The number of ride tickets that were sold are 8 and the number of food tickets that were sold  are 24  .

The given question is incomplete , the complete question is

A family buys a total of 32 tickets at a carnival. Ride tickets cost $1.50 each and food tickets cost $3.25 each. The family pays a total of $90 for the tickets store. How many of each type of ticket were sold ?

Based on the information provided, ETS is an abbreviation for these three terms (Error, Trend, and Season). Following that, Exponential Smoothing Methods for an ETS system can be described, with the details specified in a smoothing style.

=> As should be obvious, combining Error, Trend, and Season on any occasion in three distinct ways yields a plethora of combinations.

=> The trend depicts the overall layout of the time. It communicates with the data's drawn-out model — its tendency.

=> The seasonal section displays the types associated with anticipated events. Finally, the error component explains what the season and trend components do not. The error is due to the disparity between the first data and the combination of trend and seasonality. As a result, if we crystallize all three parts, we will have the first data back.

=> It has a counted substance conduct when the period of seasonal swings remains constant.

The cross-sectional area is (h × w ) + ((1 ÷ 2) × 0.9 × w²) and the dimensions of the window which minimize the perimeter is (A - [tex]c_{0}[/tex][tex]w_{0}^{2}[/tex]) ÷ [tex]w_{0}[/tex] = 2√A[tex]c_{1}[/tex]([tex]c_{2}[/tex] - [tex]c_{0}c_1[/tex]) = 0.60592√A.

height of rectangle = h

height of the triangle = t

T = 0.9

width of the rectangle = w

The formula of Cross-sectional area is,

A = h × w + (1 ÷ 2)T × w

A = (h × w ) + ((1 ÷ 2) × 0.9 × w²)

Perimeter,

P = w + (2 × h) + 2√(T² + (w ÷ 2)²)

P = w + (2 × h) + 2√((0.9)² + (1 ÷ 2)²)

P = 2h + 2√((0.9)² + (1 ÷ 2)² + 1) × w

Therefore, [tex]C_{0}[/tex] = 0.9 ÷ 2, [tex]C_{1}[/tex] = 2, [tex]C_{2}[/tex] = 2√((0.9)² + (1 ÷ 2)² + 1)

P = [tex]c_1[/tex]w + ([tex]c_1[/tex](A - [tex]c_{0}[/tex]w²) ÷ w)

Differentiating both sides,

(dP ÷ dw) = -2[tex]c_{0}[/tex][tex]c_{1}[/tex] + [tex]c_{2}[/tex] - ([tex]c_{2}[/tex](A - [tex]c_{0}[/tex]w²) ÷ w²) = 0

[tex]w_{0}[/tex] = (√[tex]c_{1}[/tex]A ÷ (√[tex]c_{2}[/tex] - [tex]c_{0}c_1[/tex])) = 0.962445√A

From the recipe given by Angela, the quantity of syrup that is used to make up to 14 biscuits= 275 ml.

The quantity of sugar that is used to make up to 14 biscuits= 150g

Therefore the quantity of sugar that would be used for syrup of 3.3 liters would be= X

That is;

275ml = 150g

3.3L = X

Convert 3.3L to ml = 3,300ml , then make x the subject of formula;

X = 3300×150/275

X = 495000/275

X= 1,800g
