The round plate in the problem has a surface area of 63.754 square inches.
What is Area?The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.
Given, A circular plate has a circumference of 28.3 inches.
Since circumference of a circle = 2*3.14 * r
Where r is the radius
Thus,
circumference = 28.3
6.28 * r = 28.3
r = 4.506
Radius of circle = 4.506
Since the area of the circle = 3.14 * r * r
Thus,
Area of given circle = 3.14 * 4.506 * 4.506
Therefore, the Area of the given Circular plate is 63.754 square inches.

Erika is 12 years older than her friend Nick. She is also 3 times as old as Nick. Let x represent Nick’s current age.
Answer:
Nick is 6 years old.
Erica is 18 years old.
Step-by-step explanation:
Hello!
We know that Erica is 12 years older than Nick, which also means she is 3 times older than Nick. We can represent this situation as two equations.
Let E be Erica's age, and x be Nick's age.
E = x + 12, and E = x* 3
Since E is equal to E, we can say that x + 12 = 3x.
Solve for xx + 12 = 3x12 = 2x6 = xThe value of x is 6. Nick is 6 years old, and Erica is 18 years old.
What is an example of a perfect trinomial?.
Examples of perfect trinomials are-
x 2 + y 2 + XY,
A trinomial that can be expressed as the square of a binomial is referred to as a perfect square trinomial. Remember that the square of the first term, twice the product of the first two terms, and the court of the final time are the results of squaring a binomial. The perfect square trinomial expression can be created by taking the binomial equation's square. If and only if a trinomial satisfying the condition b 2 = 4ac has the form ax 2 + bx + c, it is said to be a perfect square. The outcome variables are (x + r) and (x + s). For instance, to factor x2 + 7x + 10, you need to find two numbers whose sums are 7 (the middle term's coefficient), and 10.To learn more about polynomials here

Mitch turns on a house at noon that fills the pool at a rate of 225 gallons per hour. He checks the water level in the pool every hour, starting at 1 PM. At what time does Mitch first see the pool overflowing?
Step-by-step explanation:
He starts at 8000 gallons when he adds 2000 gals it will overflow
120 gal go out each hour 225 gal goes in each hour net : 105 gal per hour IN

26. Scale Factor of A to B: [tex]\boxed{\dfrac{3}{4}}[/tex]
27. Scale factor of B to A: [tex]\boxed{\dfrac{4}{3}}[/tex]
Step-by-step explanation:
If two triangles are similar, the ratios of the side length to the corresponding side length of the other must be the same for all sides
The first challenge is to figure out which side of triangle A corresponds to which side of triangle B
If you flip triangle A counterclockwise by 90° the angles will be aligned with each other and it is easier to see the corresponding sides of A and B
We see that ....
side length 24 of A matches with side length 18 of B
side length 36 of A matches with side length 27 of B
side length 32 of A matches with side length 24 of B
B is of smaller size than A so the scale factor of A to B is less than 1
26.
Therefore the scale factor of A to B is
[tex]\dfrac{18}{24} = \dfrac{27}{36} =\dfrac{24}{32}\\\\\\\dfrac{18}{24}= \dfrac{3}{4} \cdots \textrm { by dividing numerator and denominator by 6}[/tex]
[tex]\dfrac{27}{36} = \dfrac{3}{4} \cdots \textrm { by dividing numerator and denominator by 9}\\\\\\\dfrac{24}{32} = \dfrac{3}{4} \cdots \textrm { by dividing numerator and denominator by 8}\\\\\\[/tex]
So the scale factor of Figure A to Figure B is [tex]\dfrac{3}{4}[/tex]

The scale factor of Figure B to Figure A is the reciprocal of

The measure of ∠V of the parallelogram is = 150.5°
What is a Parallelogram?A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure
The four types are parallelograms, squares, rectangles, and rhombuses
Properties of Parallelogram
Opposite sides are parallel
Opposite sides are congruent
Opposite angles are congruent.
Same-Side interior angles (consecutive angles) are supplementary
Each diagonal of a parallelogram separates it into two congruent triangles
The diagonals of a parallelogram bisect each other
Given data ,
Let the measure of the angle ∠Y = 10x + 27
Let the measure of the angle ∠W = 2x + 29
Now , for a parallelogram the opposite sides are congruent and opposite angles are congruent
Substituting the values in the equation , we get
10x + 27 = 2x + 29
Subtracting 2x on both sides of the equation , we get
8x + 27 = 29
Subtracting 27 on both sides of the equation , we get
8x = 2
Divide by 8 on both sides of the equation , we get
x = 1/4
Let the measure of the angle ∠Y = 10 ( 1/4 ) + 27
Let the measure of the angle ∠Y = 2.5 + 27
Let the measure of the angle ∠Y = 29.5°
Now , same-side interior angles (consecutive angles) are supplementary
Substituting the values in the equation , we get
angle ∠Y + angle ∠V = 180°
29.5° + m∠V = 180°
Subtracting 29.5 on both sides of the equation , we get
m∠V = 150.5°
Hence , the measure of m∠V = 150.5°

Step-by-step explanation:
solve:16^x+64=5*4^x-1
Y = [tex]4^{x}[/tex] + 64 = 5y - 1, x = (5y - 65)/16, and x = (20*[tex]4^{x}[/tex] - 260). Take the logarithm of both sides, apply the laws of logarithms, and solve for x.
What is logarithm?A logarithm is a mathematical function for expressing the relationship between two integers. It is the exponent to which a base number must be increased in order to equal a particular number. The base-10 logarithm of 100, for example, is 2, because 10 to the power of 2 equals 100.
Let y = [tex]4^{x}[/tex]
[tex]16^{x}[/tex] + 64 = 5y - 1
[tex]16^{x}[/tex] = 5y - 65
Dividing both sides by 16
x = (5y - 65)/16
x = (5*[tex]4^{x}[/tex] - 65)/16
Substituting y = [tex]4^{x}[/tex]
x = (5*([tex]4^{x}[/tex]) - 65)/16
Simplifying,
x = (5*[tex]4^{x}[/tex] - 65)/16
x = (20*[tex]4^{x}[/tex] - 260)/16
Divide both sides by 20
x = ([tex]4^{x}[/tex] - 13)/2
Take the logarithm of both sides:
log(x) = log([tex]4^{x}[/tex] - 13)/2
Apply the laws of logarithms:
log(x) = x*log(4) - log(13)/2
Solve for x:
x = (log(13)/2)/log(4) - log(x)/log(4)
x = (log(13)/2 - log(x))/log(4)

They will win 100 games if the team rate continues through a 148-game season.
We will solve our question with the help of the Multiplication rule.
As per the question, the baseball team has won 25 games and lost 12 games. This will give us a total of 25+12= 37 games.
It is given that if the baseball team rate continues through a 148-game season which is 37*4 = 148 games.
So, we should multiply our initial won matches by 4 to get the final won matches as per the given condition, we will get:
25*4 = 100 matches.
We can also find the answer by:
You would multiply 25 by 148 divided by 37 to determine the number of games won if you were comparing the 25 of the 37 games won to the total of 148 games played.
(148*25)/(25+12)

if f(x) = x^3 -12x^2 + 29x + 42 and f(7) = 0, then find all zeros of f(x) algebraically
The zeroes of the polynomial f(x) are 7, 6 and -1. The solution is obtained by the method of polynomial long division.
What is polynomial long division?
A long division polynomial is a formula for dividing one polynomial by another of the same degree or lower. The divisor, quotient, dividend, and remainder are all components of the long division of polynomials, just like they are for long division of numbers.
We are given f(7) = 0.
This means that (x-7) is one factor of f(x).
Using Polynomial Long Division,
Dividing : x^3 -12x^2 + 29x + 42 ("Dividend")
By : x-7 ("Divisor")
Dividend x^3 - 12x^2 + 29x + 42
- divisor * x2 x^3 - 7x^2
Remainder - 5x^2 + 29x + 42
- divisor * 5x - 5x^2 + 35x
Remainder - 6x + 42
- divisor * (-6) - 6x + 42
Remainder 0
Quotient : x^2-5x-6
Remainder: 0
Now, factoring x^2-5x-6 , we get
⇒x^2-6x+x-6
⇒x(x-6)+1(x-6)
⇒(x+1)(x-6)
Thus, the factors are (x+1), (x-6) and (x-7).
Hence, the zeroes of the polynomial f(x) are 7, 6 and -1.
