1. The county fair charges $1.25 per ticket for the rides. Jermaine bought 25 tickets for the rides and spent a total of $43.75

natita [175]

Answer:

(a) The variables are y which represent total cost and x which represent the number of ride tickets.

(b) Linear equation = <em>y </em>= 1.25<em>x</em> + 12.50.

(c) Total cost (<em>y</em>) is the sum of total amount spent on the ride tickets and price of fair admission. Therefore, if a person buy x number of ride tickets having the price $ 1.25 per ride ticket, then the total amount spent by the person on <em>x</em> tickets is 1.25<em>x.</em>The Price of fair admission is 12.50 dollars which is same for everyone.

Step-by-step explanation:

Let the total cost be<em> y</em> and number of ride tickets be <em>x.</em>

Price of one ride ticket =<em> $</em> 1.25

Total amount spent by Jermaine on 25 rides tickets = 25 × <em>$</em> 1.25 = 31.25<em> $</em>

Total amount spent at the fair By jermain= 43.75<em>$</em>

Total amount spent at the fair =<em> </em>Price of fair admission + cost of 25 ride tickets<em> </em>

Price of fair admission = Total amount spent at the fair - cost of 25 ride tickets

Price of fair admission = 43.75<em>$ - </em>31.25<em> $ </em>= 12.50<em>$</em>

Now,

Price of one ride ticket = <em>$</em> 1.25

Price of fair admission per person = 12.50<em>$</em>

So, linear equation that represent the total cost of a person who only pays for ride tickets and fair admission:

<em>y </em>= 1.25<em>x</em> + 12.50.

where y is the total cost, x is the number of tickets for rides bought by any person.

2 groups of 10 tiles and 2 groups of 3 tiles. Which explains whether or not this model accurately shows 26 ÷ 2? It does because

WINSTONCH [101]

Answer:

It does because 26 = 20 + 6, and the model shows 2 groups of 10 and 2 groups of 3.

Step-by-step explanation:

Two groups of 10 make 20. Two groups of 3 make 6.

20 + 6 = 26

B is wrong. The model does not show two groups of 6.

C is wrong. The model should show one group of 6..

D is wrong. The model should show two groups of 10 and one group of 6.

A circle with radius of \greenD{5\,\text{cm}}5cmstart color #1fab54, 5, start text, c, m, end text, end color #1fab54 sits insid

Marat540 [252]

Answer:

The area of the shaded region is 42.50 cm².

Step-by-step explanation:

Consider the figure below.

The radius of the circle is, <em>r</em> = 5 cm.

The sides of the rectangle are:

<em>l</em> = 11 cm

<em>b</em> = 11 cm.

Compute the area of the shaded region as follows:

Area of the shaded region = Area of rectangle - Area of circle

$=[l\times b]-[\pi r^{2}]\\\\=[11\times 11]-[3.14\times 5\times 5]\\\\=121-78.50\\\\=42.50$

Thus, the area of the shaded region is 42.50 cm².
