what is 258 divided by 4?
The quotient of 258 divided by 4 is calculated to be 64.5
Division is considered to be one of the four basic operations of arithmetic. The other three are multiplication, addition, and subtraction, and they can be defined as how numbers are combined to make new numbers.
Out of the four basic operations, division is the process of splitting an amount or a number into equal parts.
In division, the numerator is the top number of a fraction, and on the other hand, the denominator is the bottom number of a fraction and the result of division is called the quotient
In this case, 258 is the numerator and 4 is the denominator;
258 / 4 = 64.5
Therefore the quotient of this division is calculated to be 64.5

Step-by-step explanation:
What is the solution to the system of equations?
y = 3x - 4
2y - 6x = -8
Answer:
Infinite solutions.
Any number.
Step-by-step explanation:
First, substitute one of the variables, x or y into one of the equations.
Since y is already isolated, substitute it in 2y - 6x = -8.
2 (3x - 4) - 6x = -8
Distribute 2 to 3x and -4.
6x - 8 - 6x = -8
Bring like terms together.
6x - 6x - 8 = -8
move -8 over to the other side of the equation and change its sign.
Or just add 8 to both sides (it is the same thing.)
You add 8 because it is to cancel out the negative 8 and get rid of it.
6x - 6x = -8 + 8
This equals 0 = 0 so there are infinite solutions to this system of equations.
Find the area of the shaded portion in the equilateral triangle with sides 6. Show all work for full credit.
(Hint: Assume that the central point of each arc is its corresponding vertex.)
The area of the shaded portion in the equilateral triangle with sides 6 is 9√3 - 36π.
To find the area of the shaded portion in the equilateral triangle, we need to determine the area of the three arcs and subtract it from the area of the equilateral triangle.
First, let's find the area of one arc. Each arc has a radius equal to the length of the side of the equilateral triangle, which is 6. The formula for the area of a sector is A = (θ/360)πr², where θ is the central angle in degrees.
In an equilateral triangle, each interior angle measures 60 degrees, so the central angle of the arc is 120 degrees (360 degrees divided by 3). Plugging these values into the formula, we get A_arc = (120/360)π(6)² = (1/3)π(6)² = 12π.
Since there are three identical arcs, the total area of the arcs is 3 times the area of one arc, which is 3(12π) = 36π.
Now, let's find the area of the equilateral triangle. The formula for the area of an equilateral triangle is A_triangle = (√3/4)s², where s is the length of a side.
Plugging in the value of the side length, we have A_triangle = (√3/4)(6)² = (√3/4)(36) = 9√3.
Finally, we subtract the area of the arcs from the area of the equilateral triangle to find the shaded portion's area: A_shaded = A_triangle - A_arc = 9√3 - 36π.

Graph that line with slope -1 passing through the point (-2,4)
Answer:
To graph the line with slope -1 passing through the point (-2,4), we can use the point-slope form of the equation of a line, which is:
y - y1 = m(x - x1)where m is the slope of the line, and (x1, y1) is the given point on the line. Substituting the given values, we get:
y - 4 = -1(x - (-2))Simplifying this equation, we get:
y - 4 = -x - 2y = -x + 2Now we can graph this line by plotting the given point (-2,4), and then using the slope of -1 to find one or more additional points on the line. We can do this by starting at the given point and then moving one unit down (since the slope is negative) and one unit to the right (since the slope is -1). This gives us the point (-1,3). We can then connect these two points to graph the line.

Express as a product. 1+2cos a
Answer:
Therefore, 1 + 2cos a can be expressed as the product of 2 and (cos a/2 + 1).
1 + 2cos a = 2(cos a/2 + 1)
Step-by-step explanation:
We can use the trigonometric identity:
cos 2a = 1 - 2 sin^2 a
to rewrite 1 + 2cos a as:
1 + 2cos a = 1 + 2(1 - sin^2 a/2)
= 1 + 2 - 2(sin^2 a/2)
= 3 - 2(sin^2 a/2)
Now, using another trigonometric identity:
sin a = 2 sin(a/2) cos(a/2)
we can rewrite sin^2 a/2 as:
sin^2 a/2 = (1 - cos a)/2
Substituting this into the expression for 1 + 2cos a, we get:
1 + 2cos a = 3 - 2((1 - cos a)/2)
= 3 - (1 - cos a)
= 2 + cos a
Therefore, 1 + 2cos a can be expressed as the product of 2 and (cos a/2 + 1).
1 + 2cos a = 2(cos a/2 + 1)

The difference between two numbers is 9. Four times the larger number plus one-half the smaller is 45. What are the numbers?
Answer:
To solve this problem, we will use the following steps:
Step 1: Let's assume that the larger number is x and the smaller number is y, we know that the difference between the two numbers is 9, so we can write the equation: x-y = 9
Step 2: We know that Four times the larger number plus one-half the smaller is 45, so we can write the equation: 4x + 0.5y = 45
Step 3: Now we have two equations with two unknowns, we can solve for one of the unknowns by isolating it in one of the equations.
x-y = 9
x = y+9
Step 4: Now we can substitute the value of x in the second equation
4(y+9) + 0.5y = 45
4y + 36 + 0.5y = 45
4.5y + 36 = 45
4.5y = 9
y=2
Step 5: We can substitute the value of y in one of the equation, to find the value of x
x-2 = 9
x = 11
Final Answer: The two numbers are 11 and 2.

hich linear function has the steepest slope?
y = negative 8 x + 5
y minus 9 = negative 2 (x + 1)
y = 7 x minus 3
y + 2 = 6 (x + 10)
The function with the steepest slope is \(y = 7x - 3\).
The correct answer is C.
The linear function with the steepest slope is the one with the highest absolute value for the coefficient of x.
Let's compare the coefficients of x in each of the given functions:
\(y = -8x + 5\)
Slope: -8
\(y - 9 = -2(x + 1)\)
Simplifying, we get \(y - 9 = -2x - 2\)
Rearranging, we have \(y = -2x + 7\)
Slope: -2
\(y = 7x - 3\)
Slope: 7
\(y + 2 = 6(x + 10)\)
Simplifying, we get \(y + 2 = 6x + 60\)
Rearranging, we have \(y = 6x + 58\)
Slope: 6
Therefore, the steepest slope is the \(y = 7x - 3\).

If you owe $50,000.00 at a 5% interest rate you are paying off over twentyyears, how much money will you pay each month? Search your way for thisanswer329.98
This problem seems to be about simple interest rates, which is defined by the formula
\(P=\frac{a}{\frac{(1+r)^n-1}{r(1+r)^n}}=\frac{a\cdot r(1+r)^n}{(1+r)^n-1}\)Where P refers to the payment per month, r refers to the interest rate (divided by the number of months per year), t is time in years, n is the number of periods per year.
This formula is about amortized loan payments.
According to the problem, the final amount is unknown, the principal is $50,000.00, the interest rate is 0.05 (5%) and the time is 20 years. So, we need to substitute each value in the formula to find the amount we'll pay after the interest
\(P=\frac{50000\cdot0.004166666(1+0.004166666)^{240}}{(1+0.004166666)^{240}-1}=329.98\)This means we are gonna pay back $329.76 per month.
It's important to consider that the rate r is found by dividing the interest 0.05 and the total months per year which are 12
\(\frac{0.05}{12}=0.041666666666\ldots\)As you can observe, this is an infinite decimal number, so we take many decimal numbers as we need to get 329.98.

Evaluate the expression
if x = 2, y = 3, and z = 4.
2x²-y + 2(z-1)
Answer:
11
Step-by-step explanation:
Substituting the values of x, y, and z into the expression, we get:
2x² - y + 2(z-1) = 2(2)² - 3 + 2(4-1)
= 2(4) - 3 + 2(3)
= 8 - 3 + 6
= 11
Therefore, if x = 2, y = 3, and z = 4, then the value of the expression 2x² - y + 2(z-1) is 11.
Answer:
11
Step-by-step explanation:
if x = 2, y = 3, and z = 4.
2x²-y + 2(z-1)
Substituting the given values of x, y, and z, we get:
2x² - y + 2(z-1) = 2(2)² - 3 + 2(4-1)
= 2(4) - 3 + 2(3)
= 8 - 3 + 6
= 11
Therefore, the value of the expression when x = 2, y = 3, and z = 4 is 11.
