Using the fraction concept, we can say that The number of beads each friend will get is 4.
What are fractions?
Fractions are referred to as the components of a whole in mathematics. A single object or a collection of objects might be entire. When we cut a piece of cake in real life from the entire cake, the part represents the percent of the cake. The word "fraction" is derived from Latin. "Fractus" means "broken" in Latin. The fraction was expressed verbally in earlier times. It was afterward presented in numerical form.
A piece or sector of any quantity is another name for the fraction. It is indicated by the sign "/," such as a/b. For instance, in the fraction 2/4, the lower part represents the denominator, and the top part the numerator.
In the given question, we have:
Number of bead = 32 bead;
Total number of friends = 8;
So,
we need to find how many beads will one friend get:
So,
The number of beads each friend will get : [tex]\frac{32}{8}[/tex]
The number of beads each friend will get is 4.
Hence,
using the fraction concept, we can say that The number of beads each friend will get is 4.

What is antifreeze ?
A colored liquid called antifreeze, often known as engine coolant, is combined with water to assist regulate your engine in extremely hot weather.
Let x be the amount of pure antifreeze that needs to be added
The amount of pure antifreeze added (x) plus the amount of pure antifreeze in the 5 quart of 10% antifreeze solution [ 0.1*5] should be equal to the amount of pure antifreeze in the final mixture [ 0.3*(5+x) ]
The equation obtained is:
x+[0.10*5]=0.30(5+x)
x+0.5=1.5+0.30x
x-0.30x =1.5-0.5 = 1

What is the percent of chloride ion in a sample if 2. 500 g of the sample produces 1. 750 g of agcl when treated with excess ag⁺? report your answer to two decimal places.
The percent of chloride ion in a sample if 2. 500 g of the sample produces 1. 750 g of AgCl when treated with excess ag⁺ is 17.2%
The percent of chloride can be calculate as follow:
Mass of AgCl precipitated = 1.750 g
Molar mass of AgCl = 143.32 g/mol
Molar mass of Chlorine atom = 35.45 g/mol
Asume, all the chlorine in the sample is precipitated to silver chloride. So, the mass of chlorine in silver chloride will be equal to the mass of chlorine present in the sample.
To calculate the mass of chlorine in given mass of AgCl, we apply unitary method:
In 143.32 g of silver chloride, mass of chlorine present is 35.45 g
So, in 1.3487 g of silver chloride, mass of chlorine present will be =
35.45g/143.32 g * 1.750 g = 0.43 g
To calculate the percentage composition of chlorine in pure chloride compound, as follows:
Mass of pure chloride compound = 2.500 g
Mass of chlorine = 0.43 g
% Chlorine = 0.43/2.5 *100
% Chlorine = 17.2 %
Therefore, the mass percentage of chloride in pure chloride compound is 17.2%

The length of the bae of an iocele triangle i x. The length of a leg i 4x−3. The perimeter of the triangle i 66. Find x.
Answer:
x = 8
Step-by-step explanation:
since the triangle is isosceles then the 2 legs are congruent, that is both 4x - 3
the perimeter is the sum of the 3 sides , that is
x + 4x - 3 + 4x - 3 = 66
9x - 6 = 66 ( add 6 to both sides )
9x = 72 ( divide both sides by 9 )
x = 8
vthe waitress at the restaurant provided really good service so you and your friends decided to add on an 20% tip to your $32 bill. how much money will be added onto the bill for the tip?
The answer of the given question is $6.4, this is the money that need to be added onto the bill for the tip.
How to calculate a 20% tip?
To calculate tip, we need to multiply the total bill by 1 plus the decimal percentage tip we'd like to leave. If we wanted to leave a 20% tip, we would add 1 to 0.20 to get 1.20. Then, multiply the bill by 1.20 to get the total amount we'd leave including tip.
In this case, we have a $32 bill and we would like to add on an 20% tip. So, it will be as follows:
20% = 0.20
1 + 0.20 = 1.20
Total bill will be 1.20 x $32 = $38.4
Hence, the tip amount is $38.4 - $32 = $6.4

y−3=−2(x+5)
y+3=−127(x−5)
y+3=−2(x−5)
y−3=−127(x+5)
The equation in point-slope form of a line that passes through the points (5, −3) and (−2, 9) is
y + 3 = -12/7(x - 5)
Given, a line that passes through the points (5, −3) and (−2, 9).
Now, we have to find the equation of the line in point-slope form.
As, we know to find the equation of a line,
(y - y1)/(x - x1) = (y1 - y2)/(x1 - x2)
Now, using the above formula, we get
(y + 3)/(x - 5) = (-3 - 9)/(5 + 2)
(y + 3)/(x - 5) = -12/7
On cross-multiplying, we get
y + 3 = -12/7(x - 5)
Hence, the equation in point-slope form of a line that passes through the points (5, −3) and (−2, 9) is

9. Emily measured the depth of water in a bathtub at two-minute intervals after the tap was turned off and the
stopper released. The table shows her data.
a) Make a scatter plot for the data.
b) Describe the correlation of the scatter plot.
c) What will the approximate depth be at 15 seconds?
Considering the data in the table, it is found that:
a) The scatter plot is given by the image at the end of the answer.
b) The correlation of the scatter plot is negative, as when the input increases the output decreases.
c) The estimate for the depth at 15 seconds is of 50.37 cm.
How to built the scatter plot?The scatter plot is built inserting all the points in the table, which are in the following format:
(Time, Depth).
Hence the points are given as follows:
(2, 47), (4, 41), (6, 38), (8, 37), (10, 32), (12, 24), (14, 20), (16, 19).
From both the table and the scatter plot given by the image at the end of the answer, as the input increases, the output decreases, hence the scatter plot has a negative correlation.
To make a prediction for a given input, the line of best fit has to be constructed using these points.
Inserting these points into a linear regression calculator, the line of best fit is:
y = -2.07x + 50.89.
At a time of 15 seconds = 0.25 minutes, the depth will be of:
y = -2.07 x 0.25 + 50.89 = 50.37 cm.

The given expression 7x - y = -9 in the slope intercept form can be represented as y = 7x + 9.
The expression given to us is -
7x - y = -9
We have to represent this in the slope intercept form.
The slope intercept form can be represented as -
y = mx + c
where, y = y coordinate of the line
m = slope of the line
x = x coordinate of the line
c = y intercept of the line
Thus, representing the given expression in the slope intercept form, we have
7x - y = -9
=> -y = -7x - 9
=> y = 7x + 9
Thus, the given expression in the slope intercept form can be represented as y = 7x + 9.
