The equation that represents circles that have a diameter of 12 units and a center that lies on the y-axis is x²+ (y-3)² = 36
What is Equation of Circle?The location of a circle in the Cartesian plane is represented by a circle equation. We can write the equation for a circle if we know the location of the circle's center and how long its radius is. All of the points on the circle's circumference are represented by the circle equation.
The standard equation of a circle with center at
(a, b) and radius is r.
So, the standard equation circle is
(x -a)² + (y- b)² = r²
Given:
As, we know the standard form for equation of a circle is
(x-a)² + (y-b)² = b =r²
where (a, b) is the center of the circle and r is the radius of the circle.
We have
diameter = 12 units
radius = 12/2 = 6 units
So, the center will be at (0, 3)
Thus, the equation of circle
(x-0)² + (y-3)² = 6²
x²+ (y-3)² = 36
Hence, the Equation of Circle is x²+ (y-3)² = 36.

The resulting value of the the expression 6769 x 925 by first rounding each number so that it has only 1 nonzero digit is 63,000
Round off
Round off refers a number is made simpler by keeping its value intact but closer to the next number. And it is done for whole numbers, and for decimals at various places of hundreds, tens, tenths, etc.
Given,
Here we need to estimate 6769 x 925 by first rounding each number so that it has only 1 nonzero digit.
Here we have to take individual terms to round off then we get,
By rounding 6799 so that it has only one non-zero digit is rounding it to nearest thousand.
6769 rounds to nearest thousand as 7000 as hundreds digit 7 > 5.
Similarly, by rounding 925 so that it has only one non-zero digit is rounding it to nearest hundred.
925 rounds to nearest hundred as 900 as tens digit 2 < 5.
Now, the estimated value after rounding each number so that it has only one non-zero digit is
=> 7000 x 900
=> 63000.

O $10
O $20
O $410
O $420
At the end of 6 months she will have $410 when calculated using simple interest.
What is simple interest?
Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan. The daily interest rate, the principle, and the number of days between payments are multiplied to calculate simple interest.
Main Body:
Principle =$400
Rate = 5%
Time = 6 months = 1/2 years
Simple interest = P*R*T/100
S.I. = 400*5*(1/2)/100
S.I. = 10
Hence total amount is 400+ 10= $410.

Line n contains points (4, –1) and (4, 9). Point p has coordinates (1, 6).
The distance between the line containing points (4, –1) and (4, 9) and point p (1,6) is of:
3 units.
Distance of point and lineThe standard equation of a line is given by the rule presented as follows:
ax + by + c = 0.
The coordinates of the points which we want to find the distance from the line are given as follows:
(x0,y0).
Then the shortest distance is given by the equation presented as follows:
D = |a(x0) + b(y0) + c|/sqrt(a²+b²).
The two points of the line are given as follows:
(4, –1) and (4, 9).
Since the x-coordinate is constant, the line has a slope of infinite, meaning that it is a vertical line defined as follows:
x = 4.
x - 4 = 0.
The point p has these following coordinates:
p(1,6).
Hence the distance between the point and the line is:
D = |a(x0) + b(y0) + c|/sqrt(a²+b²).
D = |1(1) + 0(6) - 4|/sqrt(1² + 0²).
D = |-3|
D = 3 units.

If LM = 2x - 9 and KN = x + 15 in rhombus KLMN, find the value of x.
The value of x in the rhombus is 24 units.
According to the question,
We have the following information:
LM = 2x - 9 and KN = x + 15 in rhombus KLMN.
Now, we know that in a rhombus opposite sides are equal. In this case, LM and KN are opposite sides.
So, we have the following expression:
2x-9 = x+15
Adding 9 to both sides of the equation:
2x = x+15+9
2x = x+24
Subtracting x from both sides of the equation:
2x-x = 24
x = 24

The total number of tongue depressors and Band-Aids are 56 and 128 respectively.
What is linear equation?A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.
Given that, a medic's bag contains individually wrapped tongue depressors (each costing 4 cents) and Band-Aids (each costing 8 cents). If the materials are worth $12.48 and there are 184 individual packages in total,
Let the number of wrapped tongue depressors be w and that of Band-Aids be b,
Therefore,
w+b= 184
0.04w+0.08b = 12.48
w+2b = 312
On solving the equation, by elimination method, we get,
b = 128
Therefore, w+128 = 184
w = 56
Hence, the total number of tongue depressors and Band-Aids are 56 and 128 respectively.

A 5.00x - 2.25x = 5000
B 5.00x + 2.25x = 5000
C 5.00x = 5000
D 2.25x = 5000
The equation that could be used to determine x, the number of purses Paula must sell to pay for the new equipment is;

How to solve equation word problems?We are told the materials costs $2.25 per purse.
She sells the materials for $5 each.
If the number of materials she purchased was x, it means that;
Selling price - Cost price = 5.00x - 2.25x
Now, we are told that she wants to invest $5000 for some new equipment. This means that she must realize at least $5000 in profit from the sales she is making of the materials.
