Answer:
Area = 13,898.5 ft^2
Step-by-step explanation:
Here, we are tasked with calculating the area of the circle given the value of the diameter.
Mathematically, the area of a circle is;
A = pi * d^2/4
Where d here is 133 feet
A = 22/7 * 133 * 133 * 1/4 = 13,898.5 ft^2
A high school graduating class is made up of 351 students. There are 73 more girls than boys. How many boys are in the class?
Answer:
let x be the number of boys
given, the number of girls are 73 more than the number of boys, meaning number of girls is x + 73
also given is that x + x + 73 = 351
2x + 73 = 351
2x = 351 - 73
2x = 278
x= 139
There are 139 boys
There will be 139 + 73 = 212 girls
139 + 212 = 351 which is the total number of students
let x be the number of boys.
Given, that the number of girls is 73 more than the number of boys, meaning the number of girls is x + 73
also given is that
x + x + 73 = 351
2x + 73 = 351
2x = 351 - 73
2x = 278
x= 139
There are 139 boys
There will be 139 + 73 = 212 girls
139 + 212 = 351 which is the total number of students.

Define polynomial with some examples.
Answer:
A Polynomial can be expressed in terms that only have positive integer exponents and the operations of addition, subtraction, and multiplication. In other words, it must be possible to write the expression without division.
Step-by-step explanation:
EXAMPLES :
x2 + 2x +5 Since all of the variables have integer exponents that are positive this is a polynomial.5x +1 Since all of the variables have integer exponents that are positive this is a polynomial.(x7 + 2x4 - 5) * 3x Since all of the variables have integer exponents that are positive this is a polynomial.5x-2 +1 Not a polynomial because a term has a negative exponent3x½ +2 Not a polynomial because a term has a fraction exponent(5x +1) ÷ (3x) Not a polynomial because of the division(6x2 +3x) ÷ (3x) Is actually a polynomial because it's possible to simplify this to 3x + 1 --which of course satisfies the requirements of a polynomial. (Remember the definition states that the expression 'can' be expressed using addition,subtraction, multiplication. So, if it's possible to simplify an expression into a form that uses only those operations and whose exponents are all positive integers...then you do indeed have a polynomial equation) [Polynomial Equation- is simply a polynomial that has been set equal to]An algebraic expression is of the form of a0+a1x+a2x2+.........+anx^n,where n is positive integer and the coefficients a0,a1,A2,.......an are constants with an is not equal to 0 is called a polynomial of degree.
A polynomial in X is denoted by p(x),q(x),g(x) etc.
Examples:
p(X)=x^2-3x+2 is a polynomial in X.
Similarly,the polynomial in two variables X and y are generally denoted by p(x,y) and polynomial in three variables is denoted by p(x,y,z).

sally has a part time job mowing lawns so she can save money for a new car. she charges $5 per hour define the independent and dependent variables
Answer:
Independent: Amount of hours she works
Dependent: Amount of money she makes
Step-by-step explanation:
The independent variable is the part of the equation that changes. In this case the only thing that changes is how long she works, the amount of money she charges and what she is doing does not change.
The dependent variable is what you measure in the equation. In this case, the amount of money she makes depends on the amount of time she works.

Which statements are true? Check all that apply. Magnitude is never a negative value. The magnitude of –1.9 is |–1.9| which is 1.9. The absolute value of a number is greater than its magnitude. The numbers –4 and 4 have the same magnitude. The magnitude of Negative two-thirds is less than the magnitude of Two-thirds.
Answer:
A, B, D
Step-by-step explanation:
The options are:
A. Magnitude is never a negative value
This is true because the magnitude is only a representation of the numerical value of a number. It is the distance of the number from the 0 point on the number line. It is the absolute value of a number.
Hence, the polarity of the number is not necessary.
B. The magnitude of –1.9 is |–1.9| which is 1.9
This is true because they have the same numerical value.
C. The absolute value of a number is greater than its magnitude
This is false because absolute value and magnitude of a number are the same.
D. The numbers –4 and 4 have the same magnitude
This is true. They have the same absolute value, hence, they have the same magnitude.
E. The magnitude of -2/3 is less than the magnitude of 2/3
This is false as already explained in C above.

Use the fact that d = rt to write the system of equations that represents the scenario. Let x be the speed of Aro's paddling and let y be the speed of the river. Upstream: 5.2 = ( ) Downstream: 5.2 = ( )
Answer:
Answer: upstream: 5.2= (x-y) 5
Downstream: 5.2= (x+y) 2.5
Step-by-step explanation:
The equations for upstream and downstream motion for time [t] seconds are -
5.2 = (x - y) t
AND
5.2 = (x - y) t
What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line in point slope form can be also written as-
[tex]y-y_{1}=m\left(x-x_{1}\right)[/tex]
We have the following problem -
Let x be the speed of Aro's paddling and let y be the speed of the river. Upstream: 5.2 = ( ) Downstream: 5.2 = ( )
We can write the equations for upstream and downstream motion for time [t] seconds as -
Upstream - (Opposing motion)
5.2 = (x - y) t
Downstream - (Supporting motion)
5.2= (x + y) (t/2)
Therefore, the equations for upstream and downstream motion for time [t] seconds are -
5.2 = (x - y) t
AND
5.2 = (x - y) t

A town's population is 33.950. About 100 people move out of the town cach month. Each month, 125 people on average move into town. A nearby
town has a population of 35,700. It has no one moving in and an average of 150 people moving away every month. In about how many months will the
populations of the towns be equal? Pick the correct equation to model the situation. Then solve the equation and answer the question,
A. 125m-100m+35,700-33,950-150m
B. 125m-100m+33,950-35,700-150m

D. 125m+100m+33,950-35,700+150m
The correct equation is choice letter
months
The towns will have equal populations in about
The equaitons are y = 25m + 33950 and y = 150m + 35700. Then the number of months will be 10 months. Then the correct option is B.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Let 'm' be the number of months and 'y' be the population. Then the equations are given as,
y = (125 - 100) m + 33,950
y = 25m + 33950 ...1
y = 150m + 35700 ...2
From equations 1 and 2, then we have
150m + 35700 = (125 - 100) m + 33950
125m - 100m + 33950 - 35700 - 150m = 0
175m = 1750
m = 10 months
The equaitons are y = 25m + 33950 and y = 150m + 35700. Then the number of months will be 10 months. Then the correct option is B.

EB and DA are diameters of circle Y. What is the measure of arc EDC?
Answer:
Option (D). 110°
Step-by-step explanation:
Since EB and AD are diameter,
[tex]m(\widehat{ECB})[/tex] = [tex]m(\widehat{ACD})[/tex] = 180°
[tex]m(\widehat{ECB})=m(\widehat{EDC})+m(\widehat{BC})[/tex] = 180° -------(1)
And [tex]m(\widehat{ACD})=m(\widehat{AB})+m(\widehat{BCD})[/tex]
180° = 40° + [tex]m(\widehat{BCD})[/tex]
[tex]m(\widehat{BCD})[/tex] = 140°
Since, [tex]m(\widehat{BCD})=m(\widehat{BC})+m(\widehat{CD})[/tex]
[tex]2m(\widehat{BC})[/tex] = 140° [Given [tex]m(\widehat{BC})=m(\widehat{CD})[/tex]]
[tex]m(\widehat{BC})[/tex] = 70°
From equation (1),
[tex]m(\widehat{EDC}})[/tex] = 180° - [tex]m(\widehat{BC})[/tex]
[tex]m(\widehat{EDC}})[/tex] = 180°- 70°
Therefore, measure of arc(EDC) = 110°
Option (D) will be the answer.
