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

When two lines intersect the vertically opposite angles so formed are Class 7?
When two lines intersect the vertically opposite angles so formed are equal in measure.
When two lines intersect each other, then the opposite angles, created due to the intersection are called vertical angles or vertically opposite angles.
We can see in the figure two lines intersect each other at a point. Therefore the two pairs of vertically opposite angles are ∠1 and ∠3, ∠2 and ∠4.
From the figure, ∠1 + ∠2 = 180° [Linear pair] eqn(1)
∠2 + ∠3 = 180° [Linear pair] eqn(2)
From eqn(1) and eqn(2), we get
∠1 + ∠2 = ∠2 + ∠3
∴ ∠1 = ∠3
Similarly, we can prove ∠2 = ∠4 also.

One year ago, Farid spent $16,600 on a new pizza oven for his restaurant, The Dough Zone.
He checked the value of his oven online and discovered it is worth $15,770 today. The
website also predicts that the oven's value will continue to decrease each year.
Write an exponential equation in the form y = a(b)* that can model the value of the pizza
oven, y, x years after purchase.
Use whole numbers, decimals, or simplified fractions for the values of a and b.
Exponential equation in the form y = a(b)* that can model the value of the pizza oven, y, x years after purchase is y = 16000(0.985625)ˣ.
The formula for an exponential function is f (x) = ax, where x is a variable and an is a constant that serves as the function's base and must be bigger than 0. The transcendental number e, or roughly 2.71828, is the most often used exponential function basis.
The development of bacteria is an illustration of an exponential function. Some germs multiply by two per hour. After x hours, you will have twice as much germs if you start with one and it doubles every hour. F(x) = 2x can be used to express this.
The exponential equation is y = a(b)ˣ

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

A, B
A, C
B, C

Each of the cuboidal blocks B and D has a volume of 24 cubic units. As a result, choice D is the right response.
What is the formula to find the volume of a cuboidal block?
The formula to find the volume of a cuboidal block is l×b×h.
The dimensions of cuboidal block A are length=6 units, breadth=2 units and height=1 units
Now, the volume of a cuboidal block A=6×2×1=12 cubic units.
The dimensions of cuboidal block B are length=4 units, breadth=2 units and height=3 units
Now, the volume of a cuboidal block B=4×2×3=24 cubic units.
The dimensions of cuboidal block C are length=5 units, breadth=3 units and height=3 units
Now, the volume of a cuboidal block C=5×3×3=45 cubic units.
The dimensions of cuboidal block D are length=6 units, breadth=2 units and height=2 units
Now, the volume of a cuboidal block D=6×2×2=24 cubic units.

The value of x is 9.32 after solving using the Pythagoras theorem.
What is Pythagoras Theorem?
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side.
The diagram has 4 corners namely - A, B, C and D.
Draw a perpendicular through B.
The intersecting point at line AD is named as E.
It can be seen in figure that EDCB is a rectangle and falls under the category of parallelogram.
So, angle ADC = angle DEB = angle AEB = 90° .
Now, side BC = ED = 5.
So, side AE = 18 - 5 = 13.
Here, it can be seen that triangle ABE is a right-angled triangle.
So, to get the measurement of side BE, apply the Pythagoras theorem -
c^2 = a^2 + b^2
Where, a is perpendicular, b is base and c is hypotenuse.
So, according to the diagram -
(16)^2 = (13)^2 - (BE)^2
(BE)^2 = (16)^2 - (13)^2
(BE)^2 = 256 - 169
(BE)^2 = [tex]\sqrt{87}[/tex]
(BE)^2 = 9.32
Now, as EDCB is a rectangle so, side BE = side CD.
Therefore, the value for side CD = x = 9.32.
