Marys need a total of 23/2 yard of fabric for his all windows.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
For example = 2 + 8 + 9
Subtraction = Minus of any two or more numbers with each other called subtraction.
For example = 4 - 8
Division = divide any two numbers or variable called division.
For example 4/8
Multiplication = to multiply any two or more numbers or variables called multiplication.
For example 5 × 7.
Given,
Fabric required in 1 larger window = 3 3/4
⇒ [(4×3)+3] /4 = 15/4
Fabric required in 1 smaller window = 1 1/3
⇒ (3+1)/3 = 4/3
Now,
Mary has 2 larger windows and 3 smaller
So,
Total fabric = 2 Larger + 3 smaller
Total fabric = 2(15/4) + 3(4/3)
Total fabric = 15/2 + 4
Total fabric = 23/2
Hence "Marys need a total of 23/2 yard of fabric for his all windows".

Music may help people relax. John got two groups of people together. He took everybody's pulse of blood pressure. The one group to listen to soothing music while other group sat in silence. After the song was over, he measured everyone's pulse and blood pressure.
What is the independent variable?
What is the dependent variable?
What are the constants or control variables?
In John's experiment, the independent variable is the condition of the groups (listening to music or sitting in silence), the dependent variables are pulse and blood pressure, and the control variables could include room temperature, the timing, the duration of the experiment, and the use of consistent measurement devices.
Explanation:In this experiment conducted by John, the independent variable is the condition under which each group is placed—which is, one group listening to soothing music and the other group sitting in silence. This is the independent variable because it's the factor that John changes or manipulates during the experiment.
The dependent variables here would be the pulse and blood pressure of the individuals in both groups. These variables are considered dependent because their values may change based on the effect of the independent variable (i.e., the type of noise the group is subjected to).
The constants, or control variables, in this experiment could include the room temperature, the timing of the experiment, the duration for which the conditions are applied (the length of the song), and the same pulse and blood pressure checking device, among others. These are the factors that remain the same throughout the experiment to ensure that the results are only influenced by the independent variable and not by any other factors.

Solve for P S=2b+ph
Answer:
P=S-2b/h
Step-by-step explanation:
To solve this equation the first thing we do is subtract 2B from both sides of the equation. S-2b=ph+2b-2b which would give us S-2B=PH. next, we divide H from both sides of the equation which would give us the answer: S-2B/h=p

A completely filled 20 gallon tank originally contains 10 pounds of salt dissolved in water. pure water enters the tank at the rate of 5 gallons/minute, and the well-stirred mixture leaves the tank at the same rate. find the amount of salt in the tank at any time t .
To find the amount of salt in the tank at any time t, we can use the equation S(t) = 10 - 10(W(t)/20), where W(t) represents the amount of water in the tank at time t. Substituting the given values, we can calculate the amount of salt in the tank.
Explanation:To find the amount of salt in the tank at any time t, we need to consider the rate at which pure water enters and leaves the tank. Since water enters the tank at a rate of 5 gallons/minute, the amount of water in the tank at any time t can be represented by the equation: W(t) = 5t, where t represents time in minutes. The concentration of salt in the tank remains constant, so the amount of salt in the tank at any time t can be represented by the equation: S(t) = 10 - 10(W(t)/20), where S(t) represents the amount of salt in pounds and W(t) represents the amount of water in gallons.
Let's solve for S(t) when t = 10 minutes:
S(10) = 10 - 10(5/20) = 10 - 10(1/4) = 10 - 10/4 = 10 - 2.5 = 7.5 pounds of salt.
Since there are 20 standard amino acids, the number of possible linear polypeptides of length n can be expressed as:
Since there are 20 standard amino acids, the number of possible linear polypeptides of length n can be expressed as [tex]20^n[/tex].
What are Amino acids?Amino acids may be defined as compounds that significantly contain carbon, hydrogen, oxygen, and nitrogen. These compounds serve as the monomers or the building blocks of proteins that are composed of an amino group, a carboxyl group, a hydrogen atom, and a specific side chain.
Two amino acids are held together by a linkage known as peptide linkage. When a number of peptide linkages are present in the structure of the protein, it is known as polypeptides.
If any polypeptide chain is derived from 20 amino acids. So, the possibility of a combination for any polypeptide chain will be [tex]20^n[/tex], where n = the number of amino acid residues in the polypeptide chain.
Therefore, since there are 20 standard amino acids, the number of possible linear polypeptides of length n can be expressed as [tex]20^n[/tex].

Solve for x: u= kx + yx
Answer:
The value of the equation for x is [tex]x=\frac{u}{k+y}[/tex].
Step-by-step explanation:
Consider the provided equation.
[tex]u= kx + yx[/tex]
We need to solve the equation for x.
Take x common from right side as shown below:
[tex]u= x(k + y)[/tex]
Divide both the sides by k+y.
[tex]\frac{u}{k+y}=\frac{x(k + y)}{k+y}[/tex]
[tex]x=\frac{u}{k+y}[/tex]
Hence, the value of the equation for x is [tex]x=\frac{u}{k+y}[/tex].

Elleanna is planning to join a DVD club and is investigating the options for membership. Option 1 is a $20 membership fee and $1.25 rental charge for each DVD rented. Option 2 has no rental fee and charges $2.50 for each DVD rented.
Let 'x' be the number of DVDs and 'y' be the total cost. Then the equations are given as,
y = 1.25x + 20
y = 2.5x

A tee-ball team for 5 year-olds has half as many girls as boys. If there are 15 children on the team, how many are boys and how many are girls?
As the has half as many females as males, the number of males in the team is 10, and the number of females in the team is 5.
What is the number of males and females in the team?Given the parameter:
A team for 5-year-olds has half as many females as males.
There are 15 children on the team.
There are half as many females as males, this can be expressed as:
Let G represents females and B represents males.
G = 0.5B
Also, there are 15 children on the team, so we can write an equation based on the total number of children:
B + G = 15
Now, we solve the system of equations:
G = 0.5B
B + G = 15
First, substitute the expression for females from the first equation into the second equation:
B + 0.5B = 15
1.5B = 15
B = 15/1.5
B = 10
Plug B = 10 into the first equation and solve for females:
B + G = 15
10 + G = 15
G = 15 - 10
G = 5
So, there are 10 males and 5 females on the team.
