Answer: A loss of 6 dollars
Step-by-step explanation:
Step 1 is to determine how many eggs she purchased:
3 dozen eggs * 12 eggs per dozen = 36 eggs purchased
Step 2 is to find the cost of the eggs purchased using the information you gave:
(36 eggs / 6) * 10 dollars = $60 purchase price
Step 3 is to find out how many eggs broke which is calculated like this:
36 total eggs * .25 = 9 broken eggs
Step 4 is to find how much money she made from selling the remaining eggs:
(36 total eggs - 9 broken eggs) * $2 per egg = $54 resale
Step 5 is finding the profit or loss:
$54 resale price - $60 purchase price = $ -6 (aka a 6 dollar loss)

The total cost in dollars for ordering 5 tickets is $108. 0. Which linear function represents c, the total cost, when x tickets are ordered? c(x) = 5. 50 + 20. 50x c(x) = 5. 50x + 20. 50 c(x) = 5. 50 + 21. 60x c(x) = 5. 50x + 21. 60.
The Linear function representing the total cost , where x is the number of tickets is c(x) = 5. 50 + 20. 50x , the correct option is (a) .
In the question ,
it is given that ,
the total cost for 5 tickets = $108
the service fees for the tickets to a basketball game = $5.50
we need to find the cost function for 5 tickets .
we substitute , the value of x = 5 in each option and check which option gives the cost as $108 .
Option (a)
c(x) = 5.50 + 20.50x
= 5.50 + 20.50(5)
= 108
Option(b)
c(x) = 5. 50x + 20. 50
= 5.50(5) + 20.50
= 48
Option(c)
c(x) = 5. 50 + 21. 60x
= 5.50 + 21.60(5)
= 113.5
Option(d)
c(x) = 5. 50x + 21. 60
= 5.50(5) + 21.60
= 49.1
So, from the answers above we can conclude that the cost function representing the cost for 5 tickets is c(x) = 5. 50 + 20. 50x .
Therefore , The Linear function representing the total cost , where x is the number of tickets is c(x) = 5.50 + 20.50x .
The given question is incomplete , the complete question is

use the communitive property to simplify the expression. 1/3 + 3/5 + 2/3
The simplified expression using the commutative property is in the first option : 1/3 + 2/3 + 3/5 = 1 + 3/5 = 1 3/5 .
now the given expression is 1/3 + 2/3 + 3/5 .
Therefore this expression can be simplified using the commutative property where we put the like terms together.
1/3 + 3/5 + 2/3
= 1/3 + 2/3 + 3/5 (here we use commutative property on the second and third terms of the expression)
= 1 + 3/5 (we know that 1/3 +2/3 = 1)
=1 3/5
Hence by using the commutative property we calculate the sum easily.
The commutative property applies to the arithmetic operations of addition and multiplication. This suggests that no matter how the numbers are arranged or placed, the result of adding or multiplying them remains the same.
As an illustration, 1 + 5 = 6 and 5 + 1 = 6. No matter how two numbers are added, the sum is unaffected. Multiplication uses the same principle. The commutative property does not hold for division and subtraction because the results are completely different when the numbers are rearranged.

two cars start moving from the same point. one travels south at 60 miles per hour. the other car travels west at 25 miles per hour. at what rate is the distance between the cars increasing 2 hours later?
The distance between the cars increasing 2 hours later is 65mph
Let’s say, the velocity in the west is x, the velocity in the south is y, and the distance between them is s at any time t. Since the west and south directions are perpendicular to each other, this will be for a right-angled triangle.
So, we have [tex]x^2 + y^2 = s^2[/tex] --------------(1)
(please note all of them are changing as t increases.)
So, x=u×t and y=v×t,
so using (1), we can write
[tex][(u\times t)^2 + (v\times t)^2] = s^2[/tex]
[tex]s= \sqrt{(u^2 + v^2)}* t[/tex]
Using the value of u and v,

The tons of waste recycled in 2021 was 619.4286 tons.
According to the question,
We have the following information:
In 2021: There were 2341 people living in the town. Each person in the town recycled an average of 264.6kg of waste. Aleks knows that 1 ton = 1000kg.
Now, the total waste recycled in 2021 can be found using multiplication:
Number of people*waste recycled by each person
2341*264.6
619428.6 kg
Now, we will convert this from kilogram to tons.
1 ton = 1000 kg
1 kg = 1/1000 ton
So, we will divide the waste in kilogram by 1000:
Total waste recycled = 619428.6/1000
Total waste recycled = 619.4286 tons
Hence, the tons of waste recycled in 2021 was 619.4286 tons.

In a set of eight consecutive integers, the smallest integer is more than $\frac35$ of the largest integer. What is the smallest possible value of the sum of the eight integers?
The smallest possible value of the sum of the eight integers is given by:
116.
What are the integers?The eight integers in the problem are given as follows:
n, ..., n + 7.
Hence:
The smallest integer is of n.The largest integer is of n + 7.The smallest integer is more than 3/5 of the largest integer, hence the following inequality is built to relate them:
n > 3/5(n + 7)
Applying the distributive property on the right side, we have that:
n > 0.6n + 4.2.
0.4n > 4.2
n > 4.2/0.4
n > 10.5.
Hence the integers are:
11, 12, 13, 14, 15, 16, 17, 18.
(as 11 is the smallest integer possible).
Then the value of the sum is obtained as follows:
11 + 12 + 13 + 14 + 15 + 16 + 17 + 18 = 116.

According to the definition, midpoint refers the central point between the two points.
So, in a simple manner we have said that the mid point is calculated by finding the average of the two given point.
For example, (x₁, y₁) and (x₂, y₂) are the points, then the midpoint (xₙ, yₙ) is calculated by using the formula,
(xₙ, yₙ) = ( (x₁ + x₂)/2 , (y₁ + y₂)/2)

Ian buys a two-gallon bottle of juice for $28.16. What is the unit rate of the cost of the juice per fluid ounce?
1 gallon = 4 quarts
1 quart = 2 pints
1 pint = 2 cups
1 cup = 8 fluid ounces
Before you try that problem, answer the question below.
How many fluid ounces of juice did Ian buy?
Answer: 11 Cents per ounce of Juice
Step-by-step explanation:
The first step here is going to be to find how many ounces are in a gallon. This can be determined as shown using the given information you stated above:
1 gallon * 4 quarts * 2 pints * 2 cups * 8 ounces = 128 ounces in 1 gallon
Step 2 is multiplying 128 ounces by 2 because we have two gallons of juice in the bottle:
128 ounces per gallon* 2 gallons = 256 ounces
Step 3 is dividing the total cost of the juice, which is $28.16, by the number of total number ounces (256)
$28.16 / 256 ounces = .11 dollars per ounce (aka 11 cents per ounce)
