What is Division?Division is a simple operation in which a number is divided.
Division lets us separate a number of objects into equal-size groups.
Division has 3 important parts dividend, divisor, remainder and quotient.
1.168 ÷ 8= 0.146
(Because 0.146*8=1.168)
2.246÷12= 0.1871
(Because 12*0.1871=2.246)
3.4328÷4=0.8582
(Because 4*0.8582=3.4328)
4.729÷9=0.5254
(Because 9*0.5254=4.729)
5.8415÷5=1.168.
(Because 5*1.168=5.8415)
Therefore 1.168 ÷ 8= 0.146, 2.246÷12= 0.1871, 3.4328÷4=0.8582, 4.729÷9=0.5254 and 5.8415÷5=1.168.

In a given bag of M & M's, 16 were yellow, 15 were green, 21 were brown, and 11 were red.
How many M&M's were in the bag?
What fraction were yellow?
What fraction were green?
What fraction were brown?
What fraction were red?
Answer:
There are 63 M&M's in the bag when all of them are added together.
16 out of 63 (16/63) were yellow.
5 out of 21 (5/21) were green. This answer is simplified. The original is 15/63.
1 out of 3 (1/3) were brown. This answer is simplified. The original is 21/63.
11 out of 63 (11/63) were red.
Tip:
To find the fraction of something, put the total on the bottom and the wanted portion on the top.
Example: 5 yellow and 10 red birds were in a cage. Which fraction were yellow?
We put the total of birds (5+10 = 15) on the bottom and the portion wanted ("5 yellow") on the top. The fraction is 5 out of 15 (5/15). This fraction can be simplified because 5 goes into 15 three times (5 x 3 = 15), so divide the fraction 5/15 by 3 to get 1/3. (5 goes into 5 one time.)

In quartic equation, The player will catch the ball on its way down, at about 4.346 seconds. .
What is the quartic equation's formula?
It might be argued that using this formula makes it possible to solve the quadratic with a pencil. Ax4 + bx3 + cx2 + dx + e = 0 is an analogous formula for the generic quartic equation.h = -16t2 + 70t + 4
We want to know how many seconds it takes for the ball to be 6 feet above the ground.
We want to know the value of t when h = 6 . So plug in 6 for h and solve for t .
6 = -16t2 + 70t + 4 Subtract 6 from both sides of the equation.
0 = -16t2 + 70t - 2 Let's solve this quadratic equation using the quadratic formula.
t = -70 ± √70² - 4( -16)(-2)/2(-16)
t = -70 ± √4900 -128/ -32
t = -70 ± √4772/ -32
t = -70 + √4772/ -32 ≈ 0.029
t = -70 - √4772/ -32 ≈ 4.346
So we know that
(a) at 0.029 seconds, the ball is 6 feet above the ground and on its way up, and
(b ) at 4.346 seconds, the ball is 6 feet above the ground and on its way down.
The player will catch the ball on its way down, at about 4.346 seconds.

Joel digs a hole at a rate of 3/5 feet every 10 minutes. After digging for 30 minutes, Joel places a bush in the hole that fills exactly 1/2 feet of the hole. Relative to ground level, what is the elevation of the hole after placing the bush in the hole? Enter your answer as a simplified mixed number in the box.
After excavating and inserting bushes, the hole's elevation in feet is 1 1/10 feet.
3/5 feet per 10 minutes are dug up on average.
After 30 minutes, the elevation or depth of the hole:
3/5 × (30/10) = (3/5 × 3) = 9/5 feets
Consequently, after 30 minutes, the hole's height will be 9 1/2 feet.
Elevation after planting bushes in half of the hole:
After 30 / 2 minutes, the hole's elevation was 2/ (9/5)
=2/(9 /5 )
= (9 /5 ) × 1/2
= 9/10 feet.
Consequently, the hole is elevated by 1 1/10 of a foot above the surrounding ground.

If 3sinθ + 4cosθ = 5, Prove that tanθ= 3/4.
I'll use x in place of θ
Let's isolate the sine term and then square both sides
3sin(x) + 4cos(x) = 5
3sin(x) = 5-4cos(x)
(3sin(x))^2 = ( 5-4cos(x) )^2
9sin^2(x) = 25-40cos(x)+16cos^2(x)
9sin^2(x) = 25-40cos(x)+16(1-sin^2(x))
9sin^2(x) = 25-40cos(x)+16-16sin^2(x)
9sin^2(x)+16sin^2(x) = 25-40cos(x)+16
25sin^2(x) = 41-40cos(x)
25(1-cos^2(x)) = 41-40cos(x)
25-25cos^2(x) = 41-40cos(x)
Now let w = cos(x), so we now have the following
25-25w^2 = 41-40w
25w^2-40w+41-25 = 0
25w^2-40w+16 = 0
(5w - 4)^2 = 0
5w-4 = 0
w = 4/5
Therefore cos(x) = 4/5
Use the pythagorean theorem or unit circle to find that if cos(x) = 4/5, then it leads to sin(x) = 3/5. This is exactly because of the 3-4-5 right triangle.
Then lastly,
tan(x) = sin(x)/cos(x)
tan(x) = sin(x) ÷ cos(x)
tan(x) = (3/5) ÷ (4/5)
tan(x) = (3/5) * (5/4)
tan(x) = (3*5)/(5*4)
tan(x) = 3/4

Show that the set {-1, 0, 1} is closed under multiplication
The statement that the set {-1, 0, 1} is closed under multiplication, is true and can be proven.
As per the question statement, we are provided with a set {-1, 0, 1}.
We are required to determine if the above mentioned set is closed under multiplication or not.
To solve this question, we simply need to verify if the products of every distinct combination of 2 elements from the concerned set, belongs to the set itself or not, i.e., if we take any two elements "x" and "y", say, from the set "Z", then, [(x*y) ∈ Z].
Here, [tex][(-1)*0]=0[/tex], i.e., belongs to set {-1, 0, 1}.
[tex][(-1)*1]=(-1)[/tex] i.e., also belongs to set {-1, 0, 1}.
Finally, [tex](0*1)=0[/tex] i.e., also belongs to set {-1, 0, 1}.

Suppose that you invest $5800 in an account that earns interest at an APR of 4.4%, compounded monthly. Determine the accumulated balance after 7 years.
After 7 years, the total amount accumulated is $13,691.43.
What is described as annual percentage rate (APR)?An annual percentage rate (APR) is the annual interest rate charged on a loan or earned on an investment.Even before agreement is signed, financial firms must disclose the APR of a financial instrument.To protect customers from misleading advertising, the APR offers a consistent foundation for introducing annual interest rate information.For the given question;
The formula for compound interest is;
CI = P(1 + r/n)∧nt
The rate rate of interest is according to APR; r = 4.4% = 0.044
P = principal amount ($5800).
t = time in years (7 years)
n = number of times interest given per time period
n = 7×12 = 84 (as compounded monthly)
CI = 5800( 1 + 0.044/84)∧(84×7)
CI = 5800×(1.36)
CI = 7891.43
Thus, the total interest formed after 7 years.
Total amount in bank = principal amount + CI
= 5800 + 7891.43
= 13,691.43
Therefore, the total amount accumulated after 7 years is $13,691.43.

Given, we have the following sets:

Negative numbers and all entire numbers are both considered integers. A number without a decimal or fractional element is known as an integer, which encompasses both positive and negative numbers, including zero.
{0,1,2,3} = whole numbers
Whole numbers refer to all natural numbers, including zero (0). We are aware that the term "natural numbers" refers to a group of counting numbers beginning with 1, 2, 3, and so forth. Simply said, a collection of numbers that are whole numbers are those that do not contain any fractions, decimals, or even negative integers. There are zeroes and a group of positive integers in it. whereas all positive integers from 1 to infinity are included in the number system, which also contains natural numbers, which are also used for counting. There is no zero included.
{√₋1 , √₋4 , √₋5 }= Irrational numbers
We are aware that the only numbers that cannot be stated in the form of p/q, where p and q are integers and q 0, are real numbers. For instance, the numbers √5, √3, and so on are irrational.
hence we get the set which represents whole numbers but not natural numbers is {0,1,2,,3,4}
