How much will a $1.42 loaf of bread cost in 25 years based on inflation
Answer:
the bread will cost around 28 dollars.
Step-by-step explanation:
To estimate the future cost of a $1.42 loaf of bread in 25 years based on inflation, we can use the compound interest formula with an assumed average inflation rate.
Explanation:To calculate how much a $1.42 loaf of bread will cost in 25 years based on inflation, we need to consider the rate of inflation over that period. However, without that specific data, we can estimate the future cost of the bread using past inflation rates.
Let's assume an average inflation rate of 2% per year. To calculate the future cost, we can use the formula for compound interest: Future Price = Present Price * (1 + Inflation Rate)^Number of Years
For the loaf of bread, the future price will be: $1.42 * (1 + 0.02)^25 = $2.63

In a school 50% of the students are younger than 10, 1/20 are 10 years old and 1/10 are older than 10 but younger than 12, the remaining 70 students are 12 years or older. How many students are 10 years old?
Hey!
-------------------------------------------------
Solution:
1/2 are younger than 10.
1/20 are 10 years old.
1/10 are older than 10 but younger than 12.
70 are 12 years old.
Find Common Denominators.
1/2 = 10/20
1/20 = 1/20
1/10 = 2/10
Add.
10/20 + 1/20 + 2/10 = 13/20
Subtract.
20/20 - 13/20 = 7/20
So we now see that 7/20 = 70
Now we can see that 1/20 = 10
-------------------------------------------------
Answer:
There are 10 students that are 10 years old.
-------------------------------------------------
Hope This Helped! Good Luck!
Answer:
10
Step-by-step explanation:
0.50 = x<10
0.05 = 10
0.10 = 10<x<12
70 students = 12+
How many are 10 yrs old?
0.50 + 0.05 + 0.10 = 0.65
To find the percent, multiply it by 100
0.65 * 100 = 65%
70 are 35%
70/0.35 = 200 total
200 * 0.05 = 10 ten-year-old students

1. Classify the expression: 5x3 + 2x − 3
Quadratic expression
Linear expression
Cubic expression
Exponential expression
2. Choose the expression that represents a quadratic expression.
12x4 − 2x3 + 5x2 − 9x − 6
2x3 + 5x2 − 9x − 6
12x2 + 8x − 1
−8x − 1
Answer:
Part 1) Is a cubic expression
Part 2) The quadratic expression is 12x² + 8x − 1
Step-by-step explanation:
Part 1) Classify the expression: 5x³ + 2x − 3
we know that
Polynomials can be classified two different ways - by the number of terms and by their degree.
so
a) By the number of terms is a trinomial, because has three terms
b) By their degree The degree of the polynomial is found by looking at the term with the highest exponent on its variable
The highest exponent is 3 so this is a 3rd degree trinomial
therefore
Is a cubic expression
Part 2) Choose the expression that represents a quadratic expression
we know that
If the expression is a quadratic equation , then the highest exponent of the variable is 2
therefore
The quadratic expression is 12x² + 8x − 1
Answer:
1. Cubic expression
2. [tex]12x^2+8x-1[/tex]
Step-by-step explanation:
1. We have the expression [tex]5x^3+2x-3[/tex] and we have to classify it.
A quadratic expression has the form [tex]ax^2+bx+c,a\neq 0[/tex].
We can see that the first term is squared. And in the expression that we have to classify the first term is raised to the cubic, then it isn't a quadratic expression.
A linear expression has the form [tex]ax+b[/tex].
We can see that it only has two terms and the first term has exponent 1. The expression [tex]5x^3+2x-3[/tex] has 3 terms and the first term has exponent 2 then it isn't a linear expression.
A cubic expression has the form[tex]ax^3+bx^2+cx+d[/tex].
We can see that the first term is raised to the cubic. And [tex]5x^3+2x-3[/tex] is raised to the cubic.
We can rewrite it: [tex]5x^3+2x-3=5x^3+0x^2+2x-3[/tex]
[tex]a=5\\b=0\\c=2\\d=-3[/tex]
The expression [tex]5x^3+2x-3[/tex] agrees with the definition of a cubic expression. Then it's a cubic expression.
An Exponential expression has the form [tex]y=ab^x, a>0[/tex]
2. We said that a quadratic expression has the form [tex]ax^2+bx+c,a\neq 0[/tex].
Then the expression that agrees with the definition is [tex]12x^2+8x-1,a\neq 0[/tex]
With,
[tex]a=12\\b=8\\c=1[/tex]

A recipe requires 1.5 kilograms of eggs. How much is this in pounds
Answer:
3.31 pounds of eggs will be required to prepare the recipe.
Step-by-step explanation:
Since 1 kilogram = 2.205 pounds is the scale by which we can convert the unit kilograms into pounds
∵ 1 kilogram = 2.205 pounds
∴ 1.5 kilograms = 1.5 × 2.205
= 3.3069 pounds
≈ 3.31 pounds
Therefore, 3.31 pounds of eggs will be required to prepare the recipe.
How are the properties of reflection used to
transform a figure?
Answer:When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed). ... Remember that each point of a reflected image is the same distance from the line of reflection as the corresponding point of the original figure.
Step-by-step explanation:
Answer:
The properties of reflection are used when we want to reflect a figure across a specific line, it can be across y-axis, x-axis, y = x or y = -x.
In either case, the result is a reflection, that is, those lines will work as a mirror, having the same shape and size but reflected across the line.
It's important to say that a reflection is a rigid transformation, which means the shape or size of the figure won't chance.
If we want to reflect across the y-axis, the transformation is:
[tex](x,y) \implies (-x,y)[/tex]
Across the x-axis: [tex](x,y) \implies (x,-y)[/tex]
Across the line y = x: [tex](x,y) \implies (y,x)[/tex]
Across the line y = -x: [tex](x,y) \implies (-y,-x)[/tex].

For which object would a geologist use carbon-14 dating to determine age?
Answer:
The correct option is the first one. An animal skull
Step-by-step explanation:
The correct option is the first one. An animal skull
The radiocarbon dating, also referred to as carbon -14 dating, is used for the determining of the age of an object containing organic matter based on the properties of the radiocarbon.
The age detection of the ancient objects are very tough,due to no records are available about the objects.
That's why scientists use carbon-14 dating process.
In this picture, the only object that contains organic material is the animal skull, thus it is the only one that can be dated with this method.
Answer:
The correct option is animal skull
Step-by-step explanation:
Carbon-14 dating is a method for determining the age of an object containing organic material by utilising the properties of a radioactive isotope of carbon. As we have no records of the object, it's become very difficult to detect the age of an object . In such a situation, carbon-14 dating process helps .
In the given picture, animal skull is the only object that contains organic material , so it is the only object for which geologist would use carbon-14 dating to determine age.
Therefore, the correct option is animal scull ( first one )
Identity each pair

More than 5tps please help quickly
Answer:
#17 Complementary
#18 Neither
Step-by-step explanation:
Complementary Angle: If sum of two angles is right angle then both angles are complementary to each other.
Supplementary Angle: If sum of two angles is straight angle then both angles are supplementary to each other.
#17 In figure 1
∠1 + ∠2 = 90°
Sum of ∠1 and ∠2 is 90° which is right angle.
Therefore, ∠1 and ∠2 are complementary angles.
#18 In figure 1
Sum of ∠1 and ∠2 neither 90° not 180°
Therefore, ∠1 and ∠2 neither complementary angles nor supplementary angles.
