Answer:
The pack of 12
Step-by-step explanation:
1.25÷18=0.0694
0.78÷12=0.065
The packet of 12 biscuit have better value.
What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The cost of Packet of 12 biscuit = £0.78
The cost of Packet of 18 biscuit = £1.25
Now,
Since, The cost of Packet of 12 biscuit = £0.78
Hence, The cost of Packet of 1 biscuit = £0.78/12
= £0.065
And, The cost of Packet of 18 biscuit = £1.25
Hence, The cost of Packet of 1 biscuit = £1.25/18
= £0.0694
Thus, The packet of 12 biscuit have better value.

Skylar bought 23 chicken wings for $32.20. How much would it cost for 13 wings?
Answers
If Skylar bought 23 chicken wings for $32.20 then the cost of 13 wings would be using the concept of estimation.
As per the question statement, Skylar bought 23 chicken wings for $32.20. We are supposed to calculate the cost of 13 wings. We will use the concept of estimation.
Cost of 23 wings = $32.20
Cost of 1 wing = $32.20/23 = $1.40
Therefore cost of 13 wings = $1.40 * 13 = $18.20
So, if Skylar bought 23 chicken wings for $32.20 then the cost of 13 wings would be using the concept of estimation.

Jake got a part-time job to make some extra money. His goal was to make $150 per week. He was within $25 of his goal. If x represents Jake’s earnings, write an equation that represents the minimum and maximum that he could have earned.
Answers
Answer:
minimum: 125
Maximum: 175
Step-by-step explanation:
To do this, you know that Jake had a goal of getting $150 in the week. He was within $25 of reaching his goals. This means that he could have $25 less than or more than $150.
You can subtract 25 from 150 to get his minimum:
$150 - $25 = $125
And you can add 25 to get his maximum:
$150 + $25 = $175

The equation $f\left(x\right)=2x-9$ translated 6 units up is $g\left(x\right)=$ .
Answers
The equation f(x) = 2x - 9 translated 6 units up, then the equation g(x) = 2x-3
The equation is
f(x) = 2x - 9
Then it is translated 6 units up
The translation is the process of moving the shape to left/right of up or down. During the translation process the shape and size of the graph will not change. In translation we are only changing the coordinates of the points of the shape.
Here it is translated 6 units up.
During the upward motion it will be positive
g(x) = f(x) + 6
Substitute the value of f(x)
g(x) = 2x-9 + 6
g(x) = 2x-3
Hence, the equation f(x) = 2x - 9 translated 6 units up, then the equation g(x) = 2x-3

8. Stavros has 22 coins in his piggy bank, all dimes and quarters. Altogether, the
coins are worth more than $3.40. At least how many coins are quarters? At most,
how many of the coins are dimes?
Answers
Stavros has 9 at least quarters and 13 at most coins.
Define inequality.In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign (≠)" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.
Given Data
Stavros has 22 coins in his piggy bank, all dimes and quarters. Altogether, the coins are worth more than $3.40.
He only has quarters and dimes in his possession. For quarters and dimes, assign variables.
Let x = the quantity of dime
Let y = the quantity of quarters.
Create an inequality and equation to depict the scenario.
We can use an equation because he has exactly 22 coins.
x + y = 22
He has more than $3.40 in his total, thus we can apply an inequality.
0.10x + 0.25y > 3.40
To figure out how many of each coin he possesses, we apply the substitution approach. In order to express the inequality in terms of x, substitute the equation into the inequality.
0.10x + 0.25(22 - x) > 3.40
The inequality can now be resolved.
0.10x + 5.5 - 0.25x > 3.40
-0.15x + 5.5 > 3.40
-0.15x > -2.1
x > 14
In an equation where we divide by a negative coefficient, We reverse the sign in inequality.
x < 14
Stavros has a maximum of 13 dimes.
The value of x can then be substituted into the equation since an equation provides you the most precise and minimal value you can have.
y = 22 - 13
y = 9
Stavros has 9 quarters and 13 dimes.

And why there two possible solutions to the equation, X over 2 = 100?
Answers
There are two possible solutions because a power is involved. This can be shown in the graph. When we graph to the power of 2, we get a parabola. This gives us two x-intercepts, giving us two answers.
And why is this? When you square a negative number, you get a positive number since a negative times a negative is a positive.
Example: 2 * 2 equals 4, and -2 * -2 also equals 4. This means both 2² and (-2)² are equal to 4.
This means that we will get a positive and negative number value that both equal the same thing when being squared, which is why you get two possible solutions to this equation.

The cost of the entrance tickets to the zoo for 2 adults and 3 children is $78.80. the cost of the entrance tickets for 1 adult and 1 child is $33.10 . what is the cost of the entrance ticket for a child
Answers
The cost of the entrance ticket for a child is $12.80.
Using algebraic expression and equation, we can express each statement and determine the cost of the entrance ticket for a child
Let x = cost of the entrance ticket for a child
y = cost of the entrance ticket for an adult
If the cost of the entrance tickets to the zoo for 2 adults and 3 children is $78.80, then we can express this as:
3x + 2y = $78.80 (equation 1)
If the cost of the entrance tickets for 1 adult and 1 child is $33.10, then we can express this as:
x + y = $33.10 ⇒ x = $33.10 - y (equation 2)
Substitute equation 2 to equation 1 and solve for y.
3x + 2y = $78.80 (equation 1)
3($33.10 - y) + 2y = $78.80
$99.30 - 3y + 2y = $78.80
3y - 2y = $99.10 - $78.80
y = $20.30
Substitute the value of y to equation 2 and solve for x.
x = $33.10 - y (equation 2)
x = $33.10 - $20.30
x = $12.80
cost of the entrance ticket for a child = $12.80

A population numbers 17,000 organisms initially and decreases by 4% each year.
Suppose P represents population, and t the number of years of growth. Write an exponential model to represent this situation.
Answers
An exponential model to represent this situation [tex]P =17000 (0.96)^{t}[/tex]
What is exponential growth of population?Exponential growth occurs when a population's per capita growth rate remains constant regardless of population size, causing the population to grow faster and faster as it grows larger.
In exponential growth, the per capita (per individual) growth rate of a population remains constant regardless of population size, causing the population to grow faster and faster as it grows larger. In nature, populations may grow exponentially for a time, but they are eventually constrained by resource availability.
Given that,
P represents population, and
t the number of years of growth.
As we know,
P = [tex]a(b)^{t}[/tex]
[here 'a' is the initial amount of population and 'b' is the amount of growth or shrink]
To get 'b,' start at 1 and either add or remove the decimal growth rate depending on whether it is rising or decreasing.
In this case a = 17,000, it is the value of population at the time zero.
As the population decreases 4% each year, then b = 1-0.04 = 0.96
So, the equation becomes, P = [tex]17000 (0.96)^{t}[/tex]

The key is to realize that a 30 60 90 triangle can be constructed and the height of the house can be found from there. It may be helpful to draw a diagram.
I will use the diagram attached for reference to this solution.
Remember that the answer is asking for y, or the length of DE.
The angle CAB is 30 degrees, and the angle ACB is 90 degrees
The length of CB is 25 * sqrt3
Since ACB is a 30 60 90 triangle, and we know the length of one of the sides, the length of the other sides can be calculated.
CB is the shortest length, and so the middle length, AC, is sqrt(3) times longer than the length of the shortest length, CB
CB's length * sqrt 3 = AC's length = 25 * sqrt3 * sqrt3
AC = 75
length of A to F (I can't combine the letters a and f because then brainly thinks i'm swearing ) = 75 + x = 107

How much greater is the average temperature on Earth than the average temperature on Jupiter?
Answers
The average temperature on Earth is greater than the average temperature on Jupiter by 225°F.
By how many degrees Fahrenheit is the average temperature on Earth than the average temperature on Jupiter?The average temperature on earth is greater than the average temperature in Jupiter by 225°F. This can be obtained by getting the average temperatures as follows:
The average temperature on Earth is = 59°F
The average temperature on Jupiter is = -166°F.
Now we represent this in an equation as follows:
-166°F + x = 59°F
x = 59 - (-166)
x = 59 + 166
