A circular cookie cake cost 14.13 if the diameter of the cookie cake is 6 inches what is the approximate cost per square inch of the cookie cake? Use 3.14 pie 0.13 0.25. 0.50 or 0.75

Based on the amount kept and the percentage of the total it is, her total coin collection must be 80 coins.

Gianna kept 8 coins and this is 10% of her coins.

Assuming the number of coins she has is x, the expression would be:

8 coins = x× 10%

8 = 0.1x

x = 8/ 0.1

x = 80 coins

In conclusion, there are 80 coins in the collection.

Answer:

C: EAF Is the correct answer

Answer:

A: 9 seconds

B: 144 ft.

Step-by-step explanation:

A:

Let t = no. of seconds for them to meet

When they meet the sum of their distances is 270 ft, dist = rate * time

16t + 14t = 270

30t = 270

t = 270/30

t = 9 seconds

B:

He ran 9 sec at 16 ft/sec, therefore:

9 * 16 = 144 ft

The area in yards is 36 using the unit conversion of square feet to yards.

So, the given measurment of the room is 16*20 sq feet.

Now converting sqft to yards:

If the value is rounded to one decimal place, the required answer is 36 yards.

This means that the area in yards is 36 yards.

Answer:

0.5%

Step-by-step explanation:

The number of faces of each die what it indicates is the total number of events.

On the first die, it has 10 sides and an 8 must come out, that is, 1 event out of 10 possible, therefore the probability is:

1/10

On the second die, which has 20 sides, 19 or 20 can come out, that is 2 events out of 20 possible, so the probability is:

2/20

And on the third die, which is 12 sides, they tell us that an odd number can come out, the odd numbers would be 1, 3, 5, 7, 9, 11; that is, 6 events out of 12 possible, the probability would be:

6/12

Now the final probability would be the product of all:

(1/10) * (2/20) * (6/12) = 0.005

In other words, the probability of this happening is 0.5%

Answer:

To find the probability that the randomly selected point will lie inside the square, we need to find the area of the square and the area of the figure, and then divide the area of the square by the area of the figure.

The area of the square is 7 mm x 7 mm = 49 mm^2.

To find the area of the figure, we can divide it into a rectangle and two right triangles. The rectangle has dimensions of 8 mm x 14 mm, so its area is 8 mm x 14 mm = 112 mm^2. Each right triangle has base 8 mm and height 6 mm, so each triangle has an area of (1/2) x 8 mm x 6 mm = 24 mm^2. The total area of the figure is therefore 112 mm^2 + 24 mm^2 + 24 mm^2 = 160 mm^2.

The probability of selecting a point inside the square is then 49 mm^2 / 160 mm^2, which is approximately 0.3063 or 30.63%.

Therefore, the answer is closest to 26.1%, which is the third option.

Step-by-step explanation:

The numeric value of the exponential expression in this problem is given by the following option:

A. 2^12.

The exponential expression for this problem is defined as follows:

8^x/2^y.

8 is the third power of 2, hence:

8 = 2^3.

When a term is elevated to two of it's powers, the powers are multiplied, hence:

(2^3)^x = 2^(3x).

Meaning that the exponential expression is then written as follows:

8^x/2^y = 2^(3x)/2^y.

When two terms of the same base and different exponents are divided, we keep the base and subtract the exponents, hence the expression is given as follows:

2^(3x)/2^y = 2^(3x - y).

As stated in the problem, the numeric value of the expression 3x - y is given as follows:

3x - y = 12.

Hence the entire expression is simplified as follows:

2^(3x - y) = 2^12.

Meaning that the correct option is given by option A.

Answer:

8.8oz

Step-by-step explanation:

The number of ounces that can be bought for $4.40 is 8.8 ounces.

It is the conversion of one unit to another unit with its standard conversion.

Example:

1 hour = 60 minutes

1 km = 1000 m

We have,

Cost or rolled oats per pound = $8

Now,

1 pound = 16 ounces

This means,

16 ounces = $8

Multiply 4.40/8 on both sides.

4.40/8 x 16 ounces = 4.40/8 x $8

8.8 ounces = $4.40

Thus,

Answer:

Step-by-step explanation:

In the Intermediate Phase of mathematics education, one topic that demonstrates a hierarchical and logical progression in patterns, functions, and algebra is the concept of "Linear Equations."

The topic of Linear Equations in the Intermediate Phase builds upon the foundation laid in earlier grades and serves as a stepping stone towards more advanced algebraic concepts. Here is an overview of the topic sequence and content area spread for Linear Equations:

Introduction to Variables and Expressions:

Students are introduced to the concept of variables and expressions, learning to represent unknown quantities using letters or symbols. They understand the difference between constants and variables and learn to evaluate expressions.

Solving One-Step Equations:

Students learn how to solve simple one-step equations involving addition, subtraction, multiplication, and division. They develop the skills to isolate the variable and find its value.

Solving Two-Step Equations:

Building upon the previous knowledge, students progress to solving two-step equations. They learn to perform multiple operations to isolate the variable and find its value.

Writing and Graphing Linear Equations:

Students explore the relationship between variables and learn to write linear equations in slope-intercept form (y = mx + b). They understand the meaning of slope and y-intercept and how they relate to the graph of a line.

Systems of Linear Equations:

Students are introduced to the concept of systems of linear equations, where multiple equations are solved simultaneously. They learn various methods such as substitution, elimination, and graphing to find the solution to the system.

Word Problems and Applications:

Students apply their understanding of linear equations to solve real-life word problems and situations. They learn to translate verbal descriptions into algebraic equations and solve them to find the unknown quantities.

The content area spread for Linear Equations includes concepts such as variables, expressions, equations, operations, graphing, slope, y-intercept, systems, and real-world applications. The progression from simple one-step equations to more complex systems of equations reflects a logical sequence that builds upon prior knowledge and skills.

By following this hierarchical progression, students develop a solid foundation in algebraic thinking and problem-solving skills. They learn to apply mathematical concepts and procedures in a systematic and logical manner, paving the way for further exploration of patterns, functions, and advanced algebraic topics in later phases of mathematics education.

In linear equation, m² + m  is proved when any odd integer n.

What in mathematics is a linear equation?

An mathematical equation with only a constant and a first-order (linear) component, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation. Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

Given n is an odd integer.

   [n^2/4] = (n - 1/2) (n + 1/2)

L.H.S.

           [n²/4] = [( 2m + 1)²/4)]

              [4m² + 4m + 1/4]

           = [m² + m + 1/4]

            = [m² + m + 0.25]

            = [m² + m + 0.25] - [m² + m + 0.25]             {x + x  = x  }

             = [m² + m + 0.25] - 0.25

    L.H.S = m² + m

R.H.S. = (n-1) (n+ 1)/4 = n² -1/4  

            = (2m² + 1)² - 1/4

            = 4m² + 4m + 1 - 1/4

            = m² + m

  L.H.S. = R.H.S

If the lines would have intersected at two points then it would be exactly two

If the lines wouldn't have intersected each other at all there would be no solution so none.

If the lines were on top of each other there would be infinitely many solutions.
