Answer:
Below.
Step-by-step explanation:
So lets go over what we know of the first question.
Jacob took 2/6th of a pound of candy.
Louis ate 7/9th of a pound of candy.
We need to find who ate more candy.
We need to find how much more candy one person ate.
To find this information, lets get a common denominator for both fractions.
Both 6 and 9 in 2/6 and 7/9 go into 18, so:
2/18 and 7/18
Now we need to fix the numerator.
To do this, we must see how many times 6 and 9 go into 18, and then multiply the numerator by that.
So:
6 goes into 18 3 times. 3x2 is 6. So our first fraction is 6/18ths.
9 goes into 18 2 times. 7x2 is 14. So our second fraction is 14/18ths.
Now, comparing our fractions:
Jacob - 6/18
Louis - 14/18
#1 part 1 - 14/18 > 6/18
#1 part 1 - So Louis ate more candy than Jacob.
Now to find how much more, lets subtract Louis's from Jacob's:
14/18 - 6/18
=
#1 part 2 - 8/18
So the difference is 8/18
Next we have question 7.
So lets go over what we know.
We need to write division problems.
A fraction itself is a division problem.
In a fraction, the numerator is divided by the denominator.
So in our first question:
1/5 can be written as: 1 divided by 5 equals 1/5, or:
#2 part 1 - 1÷5=1/5
In our second one:
4/8 can be written as: 4 divided by 8 equals 4/8, or:
#2 part 2 - 4÷8=4/8
In our third one:
9/12 can be written as: 9 divided by 12, equalling 9/12, or:
#2 part 3 - 9÷12=9/12
Im sorry I have to go ill finish answring in like 15 minutes! Hope this will help you so far! :D
Answer:
Ok, to countinue on from what I was saying.
Step-by-step explanation:
So, lets go over what we know for #3:
Becca has 3 cookies.
She needs to divide these 3 cookies into 7 pieces.
Or, we can think of this as:
She needs to divide 3 by 7.
3÷7 is equal to 3/7, so our answer is:
#3 part 1 - 3/7
#3 part 2 - I attached a image below of this.
Next lets go over what we know for #4.
Kelsey has 25 pages.
She reads 4 6/8ths of these pages.
We need to find what she has left.
We can do this by subtrating her 25 pages by 4 6/8ths:
25-4 6/8
Well, lets start by subtracting the whole number, 25-4 is 21:
21-6/8
Now lets subtract the fraction. Since we know that there is a total of 8/8ths in 1, and we are subtracting 6/8ths, we can now look at this as:
#4 part 1 - 20 2/8
Since we took 1 from 21, making it 20. Then we subtracted 6/8 from 8/8:
8/8-6/8 = 2/8
So it was 20 2/8.
Now we are on our last question.
We need to add 1/4 to 2 1/3
First off, we need to find a common denominator.
This will be 12. So:
3/12 and 2 4/12
Now lets add them together:
#5 part 1 - 2 7/12
So this is your answer.
Hope this helps! :D

How do you tell if a graph is a function and inverse is a function?
If and only if the outcome of reflecting a function's graph about the line y = x is the function's graph, then the function f has an inverse (passes the vertical line test).
What is a function?A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X.
The sets X and Y are collectively referred to as the function's domain and codomain, respectively.
A function, according to a technical definition, is a relationship between a set of inputs and a set of potential outputs, where each input is connected to precisely one output.
The function f has an inverse if and only if the result of reflecting a function's graph about the line y = x is the function's graph (passes the vertical line test).
Therefore, if and only if the outcome of reflecting a function's graph about the line y = x is the function's graph, then the function f has an inverse (passes the vertical line test).

O(-, -28] is the formula for resolving the inequality +4 = 0. Inequality is the state of having a connection between two expressions or values that is not equal to them.
What is inequality?A connection between two expressions or values that is not equal in mathematics is referred to as an inequality. Inequality results from an imbalance, thus. In mathematics, an inequality establishes the relationship between two values that are not equal. Egality is not the same as inequality. Use the not equal symbol () in most cases when two values are not equal. To contrast values, whether they are tiny or huge, different inequalities are employed. By adjusting both sides until just the variables are left, you may eliminate many straightforward inequalities. However, several factors cause inequality: Divide or add negative values on both sides. Switch the left and right.
A disparity is presented to us.

The answer to the inequality must be discovered.
For each side of the inequality, deduct 4

How do you find the area of an acute triangle without height?
The area of the triangle is equal to the squareroot of 10(10-5)(10-7)(10-8), which is equal to 24.
The area of an acute triangle without height can be calculated using Heron's Formula. Heron's Formula states that the area of a triangle is equal to the squareroot of s(s-a)(s-b)(s-c) where s is the semi-perimeter of the triangle and a, b, and c are the lengths of the three sides.
To find the area, first calculate the semi-perimeter of the triangle. The semi-perimeter is equal to one-half the sum of the three sides. For example, if the lengths of the three sides of a triangle are 5, 7, and 8, the semi-perimeter is equal to 5 + 7 + 8 divided by 2, which is equal to 10.
Next, plug the values into Heron's Formula. Using the same triangle as an example, the area of the triangle is equal to the squareroot of 10(10-5)(10-7)(10-8), which is equal to 24.
Finally, calculate the area of the triangle by taking the square root of 24, which is equal to 4.9. Therefore, the area of the triangle is 4.9 square units.

Connor claims post-secondary education will help him get a career with a higher salary and more benefits that he can use in retirement, so the education costs will more than pay for themselves.

The area of the yellow region will be [tex]3.86[/tex] squared inches.
What is area ?Area is the space occupied by any shape.
Area of the square [tex]=side*side[/tex]
We have,

Radius of semi-circle[tex]=3[/tex] inch
Now,

Now,
Area of a semi-circle[tex]= \frac{\pi }{2}r^{2}=\frac{22 }{2*7} (3)^2=14.14[/tex] squared inches
So,
Area of two semi-circles[tex]=28.28[/tex] squared inches
Now,
Area of yellow part [tex]= \frac{36-28.28}{2}=3.86[/tex] squared inches
So, Area of yellow part is [tex]3.86[/tex] squared inches find out by dividing by two because other part is equals to yellow part.

What quadrant does (-a,b) belong
Coordinate (-a , b ) belongs to second quadrant.
What is a Quadrant?The axes (x-axis and y-axis) of a two-dimensional Cartesian plane system divide the plane into four infinite regions called quadrants. The horizontal line or x-axis and vertical line or y-axis intersect each other at the right angle. The intersection of two lines is known to be the reference point. All the measurement is done by taking this point as the reference (or starting point) in the coordinate system.
"A quadrant is simply defined as the region of a cartesian plane formed when the x-axis and y-axis intersect each other."
Given, Coordinate ≡ (-a , b)
1st Quadrant: The upper right-hand corner of the graph is the first quadrant. In this quadrant the values of x and y both are positive.
2nd Quadrant: The upper left-hand corner of the graph is the second quadrant. In this quadrant, the value of x is negative whereas the value of y is positive.
3rd Quadrant: The lower left-hand corner of the graph is the third quadrant. It contains the negative values of both x and y.
4th Quadrant: Finally, the fourth quarter is at the lower right-hand corner, which has a positive value of x and a negative value of y.
Hence, by the above observation, given coordinate (-a, b) belongs to the 2nd quadrant.
