Answer:
the daily fee is 37 and the mileage charge is .24 per mile.
Step-by-step explanation:
256 = 450x + 4b
159 = 200x + 3b
Multiple the top equations by -3 all the way through the bottom equations by 4 all the way through then add the equation together.
-768 = -1350x -12b
636 = 800x + 12b
-132 = -550x Divide both sides by -550
.24 = x This is the charge per mile.
Plug in .24 for x into either of the original 2 equations to solve for b which is the daily fee.
256 = 450(.24) = 4b
256 = 108 + 4b Subtract 108 from both sides
148 = 4b Divide both sides by 4
37 = b This is the daily fee.
Sandpiper Company ha 25,000 hare of cumulative preferred 1% tock, $150 par and 50,000 hare of $5 par common tock. The following amount were ditributed a dividend:
20Y1 $75,000
20Y2 15,000
20Y3 112,500
Determine the dividend per hare for preferred and common tock for each year. Round all anwer to two decimal place
$22500 is interest rate of common tock for each year.
What is an explanation of the interest rate?
An interest rate informs you of how much borrowing will cost you and how much saving will pay off.
Therefore, the interest rate is the amount you pay for borrowing money and is expressed as a percentage of the entire loan amount if you are a borrower.
Amount distributed as dividends = $15000
Total Preferred dividend to be paid = $37500
But Total Preferred dividend paid/avaiable = $15000
dividend per share(P.S) = $0.60 **(15000 / 25000shares)
Since the preferred stock cumulative dividend to be paid in Next year due to less payment in current year would be = $22500 or $0.90 per share
Remaining dividend = 0
Equity dividend per share = 0

An equation is an expression that shows the relationship between two or more numbers and variables.
We are given that Tony invest an initial amount of $381 for advertising, and materials cost $8 for each necklace he makes. Tony can sell his creations for $9 per necklace.
Let the number of necklace be x then;
8x + 381 = 9x
Solving;
9x - 8x = 381
x = 381
Therefore, Total expenses = 8x + 381

What is function's range ?Members of a set can congregate in mathematics.
These sets' constituents are referred to as elements. The correspondence between the two groups is known as a relation when the elements of each group are paired up together.
So, between two sets, a relation is a collection of ordered pairs of elements.
The term "function" refers to a particular type of relation where each element in the first group, referred to as the domain, corresponds to exactly one element in the second group, referred to as the range.
The elements in the domain couple with exactly one element in the range, and this is how a function is a pairing between two sets.
According to our question-
[7, ] is the interval notation.
The function's range falls between the numbers (1, ).
provided function
Determine the function's domain:
You do not want to use a counterargument to the square root in this situation (you cannot find the solution of a negative square root, at least as a real number).
What you actually do is "impose" that the argument always ends in a yes or a no (you know the square root of a positive number or zero).
You then solve for x to determine the variable's ALLOWED values by setting the argument greater than or equal to zero:
Consequently, the function is in the domain.

The measures of two vertical angles are given by the expressions (x+16)° and (2x - 3).
Find the value of x . What is the measure of each angle?
Answer:
see explanation
Step-by-step explanation:
vertical angles are congruent , then
2x - 3 = x + 16 ( subtract x from both sides )
x - 3 = 16 ( add 3 to both sides )
x = 19
Then
x + 16 = 19 + 16 = 35°
since the angles are congruent , then

Anais goes to the store to get granola bars 1 pack of 100 granola bars is $8.67.
Another pack of granola bars is 50 granola bars for $5.48. Which is the better buy?
The better option is to buy the Granola bar.
What is a unit value?
When the expenditures or value of production of an item is divided by the quantity, the result is known as a unit value. The unit value of a set of homogeneous products is the total value of the purchases/sales divided by the sum of the quantities.
To determine which is the better buy, you need to compare the price per granola bar for each option. To do this, you can divide the price of each pack by the number of granola bars it contains.
For the first pack of 100 granola bars, the price per granola bar is $8.67 / 100 granola bars = $0.09 per granola bar.
For the second pack of 50 granola bars, the price per granola bar is $5.48 / 50 granola bars = $0.11 per granola bar.
Since the price per granola bar is lower for the first pack, it is the better buy. You would save money by purchasing the first pack of 100 granola bars instead of the second pack of 50 granola bars.
Hence, the better option is to buy the Granola bar.

Find value of K for which
Y=2x+K is tangent to
y=x²-4x+4
To find the value of K, we need to find the point at which the line Y=2x+K is tangent to the parabola Y=x^2-4x+4. This means that the line and the parabola will have the same y-value at this point, and the line will be tangent to the parabola (meaning it will just touch the parabola at this point, without intersecting it).
To find the point at which the line and parabola are tangent, we can set Y=2x+K equal to Y=x^2-4x+4 and solve for x:
2x + K = x^2 - 4x + 4
x^2 - 4x + 4 - 2x - K = 0
(x-2)^2 = K
x = 2 +/- sqrt(K)
Since the line is tangent to the parabola, it will just touch the parabola at this point, which means that the parabola will have a minimum value at this point. This means that the value of K must be nonnegative, because the square root of a negative number is not a real number. Therefore, K must be equal to or greater than 0.
So, the value of K for which Y=2x+K is tangent to Y=x^2-4x+4 is K >= 0.

Which equation is equivalent to the formula d = rt? r equals d over t r = dt t equals r over d t = dr
The equation is equivalent to the r = d/t.
There are numerous ways in which one may define an equation. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side). Equations can be solved to find the value of an unknown variable representing an unknown quantity. If there is no 'equal to' symbol in the statement, it means it is not an equation. It will be considered as an expression.
We have to find which equation is equivalent to the formula d = rt.
Formula given: d = rt
Divide both sides by t
d/t = rt / t
d/t = r
Thus, the equation is equivalent to the r = d/t.

Kendra owns a restaurant. She charges $1.50 for 2 eggs and one piece of toast and $0.90 for one egg and one piece of toast. Write a system of equations that can be used to
determine how much she charges for each egg and each piece of toast.
Enter your answer in the space below.
√x
Answer:
Each egg costs $0.60
Each piece of toast costs $0.30
Step-by-step explanation:
Let's assume that the cost of a single egg is E
And the price of a toast as T
Kendra charges $1.50 for one toast and two eggs
The equation above will be
2E + T = $1.50
And the other equation is
E + T = $0.90
For the second equation, we make E the subject of the formula
E = 0.90 - T
Now substitute for this in equation 1
2E + T = 1.50
It will now be 2(0.90 - T) + T = 1.50
1.80 - 2T + T = 1.50
T= $0.30
price of one toast is $0.30
And now, for the price of an egg, we substitute T = 0.30 in the equation
E= $0.60
