The average daily balance for the given billing cycle is calculated by summing the product of each daily balance and the length of time it was held, and then dividing by the number of days in the billing cycle. After doing this, the average daily balance comes out to be $755.17.
Explanation:The subject of this question is finance and it involves calculating the average daily balance for a billing cycle. In this method, the daily outstanding balances are added together and then divided by the total number of days in the billing period.
Here, the billing cycle lasts for 29 days, from 4/17 to 5/17.
From 4/17 to 4/26 (10 days), the balance was $1,100.From 4/27 to 4/28 (2 days), the balance was reduced by $700, therefore, it was $400.From 4/29 to 5/6 (8 days), the balance increased by $300, so became $700.From 5/7 to 5/17 (11 days), the balance was reduced by $60, therefore, it was $640.Like this, you calculate the balance for each portion of the billing cycle, then multiply each by the number of days that balance was held, add those up, and finally, divide by the number of days in the billing cycle:
((1100*10) + (400*2) + (700*8) + (640*11)) / 29 = $755.17
Therefore, the average daily balance is $755.17.

Answer:
-84 is the answer.
Step-by-step explanation:
The given expression is 2 + {8 - 2[32 + 5(1 + 2)]}
We will start solving the inner most parenthesis first.
2 + {8 - 2[32 + 5×3]}
Further solve the parenthesis having the addition of 32 and 15
= 2 + {8 - 2[32 + 15]}
= 2 + {8 - 2×[47]}
Finally we will solve the last parenthesis.
= 2 + {8 - 94}
= 2 + {-86}
= 2 - 86
= -84

Answer:
12.5 :) enjoy
Final answer:
To find the value of x in the linear equation 300x + y = 10000 where y = 87.5, we substitute the value of y into the equation and solve for x. The value of x is approximately 33.04.
Explanation:
To find the value of x, we can substitute the given value of y into the equation and solve for x.
Given equation: 300x + y = 10000
Substituting y = 87.5 into the equation:
300x + 87.5 = 10000
Subtracting 87.5 from both sides:
300x = 10000 - 87.5
Simplifying the right side:
300x = 9912.5
Dividing both sides by 300:
x = 33.04
Therefore, the value of x is approximately 33.04.

Answer:
Question 1). Option C.
Question 2) Option C.
Question 3) Option D.
Step-by-step explanation:
Question 1), A. 7 - (9x + 3) = -9x -4
7 - 9x - 3 = -9x - 4
-9x + 4 = -9x - 4
Left hand side(L.H.S.)≠ Right hand side(R.H.S.)
Therefore, it's not an identity
B). 6m - 7 = 7m + 5 -m
6m -7 = 6m + 5
Again L.H.S.≠R.H.S.
So, it's not an identity.
C). 10p + 6 - p = 12p - 3(p - 2)
9p + 6 = 12p - 3p + 6
9p + 6 = 9p + 6
L.H.S.=R.H.S.
Therefore, it's an identity.
D). 3y + 2 = 3y - 2
L.H.S. ≠ R.H.S.
Therefore, it's not an identity.

Which description represents the expression 3x + 4 ?
the sum of 3 times a number and 4
4 added to 3 plus a number
4 divided by the product of 3 and a number
4 less than 3 times a number
Answer:
first option
Step-by-step explanation:
To know this, let's begin with discarting options.
The expression is 3x + 4
This expression means that you have 3 times a number and then you add 4 to that number.
According to this, the second option states that to the number 4 you add the 3, in other words 4 + 3 and then a number. This cannot be the correct option.
The third option states a division, but we don't have in the expression any division, so, this is not the option.
The fourth option is the same as the second option with the difference that instead of adding you do a substract, which is not the case.
So with this we can conclude that the correct option is the first one, sum 3 times a number with 4.
the answer is (A) the sum of 3 times a number and 4
The perimeter of a triangular plot of land is 2400 ft. The longest feet is 200 ft less than twice the shortest. The middle side is 200 ft less than the longest side. Find the lengths of the three sides of the triangular plot. ...?
Final answer:
The lengths of the three sides of the triangular plot are 600 feet for the shortest side, 800 feet for the middle side, and 1000 feet for the longest side.
Explanation:
To find the lengths of the three sides of the triangular plot, let's define the shortest side as x. Therefore, according to the problem statement, the longest side would be 2x - 200 feet and the middle side would be (2x - 200) - 200 = 2x - 400 feet. The perimeter of the triangle is the sum of all its sides, which is given as 2400 feet.
The equation representing the perimeter of the triangle is:
x + (2x - 200) + (2x - 400) = 2400
Simplifying the equation, we get:
5x - 600 = 2400
Adding 600 to both sides:
5x = 3000
Dividing by 5 gives us:
x = 600
Thus, the shortest side is 600 feet, the longest side is 2(600) - 200 = 1000 feet, and the middle side is 1000 - 200 = 800 feet.
The lengths of the three sides of the triangular plot are 600 feet, 800 feet, and 1000 feet respectively.

Step-by-step explanation:
m<AOB = 4x - 1; m<BOC = 2x + 15; m<AOC = 8x + 8
Find the value of x.
By setting up an equation using the measures of adjacent angles AOB, BOC, and AOC, we find that the sum of AOB and BOC equals AOC. Simplifying and solving for x gives us the value of x as 3.
Explanation:To solve for the value of x given the measures of angles AOB, BOC, and AOC, we have to use the fact that the sum of the angles AOB and BOC is equal to the angle AOC since the angles are adjacent to each other.
By setting up an equation where m + m equals m, we have:
(4x - 1) + (2x + 15) = (8x + 8).
Upon simplifying, we combine like terms to get:
4x + 2x - 1 + 15 = 8x + 8,
which simplifies to 6x + 14 = 8x + 8. To solve for x, we need to move the terms involving x to one side and the constant terms to the other side. Subtracting 6x from both sides of the equation yields:
14 = 2x + 8,
and then subtracting 8 from both sides gives us:
6 = 2x,
Divide both sides by 2, and we find that:
x = 3.

if the domain of a function that is reflected over the x axis is (3,4)(2,-1)(-1,2) what is the range? answers asap plz
The range of the reflected function consists of these reflected y-values. The range of the reflected function is (-4, -2, 1).
The range of a function reflected over the x-axis can be determined by considering the y-values of the original domain. In this case, the given domain points are (3,4), (2,-1), and (-1,2). The reflected points will have the same x-coordinates but opposite y-coordinates. Therefore, the reflected range will be the set of y-values obtained by changing the signs of the y-values in the original domain.
The original domain points have y-values of 4, -1, and 2. When reflected over the x-axis, these y-values become -4, 1, and -2, respectively.
Thus, the range of the reflected function consists of these reflected y-values. The range of the reflected function is (-4, -2, 1).

B. The slope of f(x) is less than the slope of g(x).
C. The slope of f(x) is greater than the slope of g(x).
D. The slope of f(x) is undefined and the slope of g(x) is negative.
Answer:
Option A is correct that is the slope of f(x) is the same as the slope of g(x).
Step-by-step explanation:
We have been given a function g(x)= -2x -5
And slope of f(x) can be shown from the given graph
And a line (0,3) and (1,1) is f(x)
Slope we can find in f(x) by the formula
[tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
Here, in f(x) [tex]x_1=0,x_2=1,y_1=3,y_2=1[/tex]
On substituting the values we get slope of f(x) as:
[tex]slope=\frac{1-3}{1-0}=-2[/tex]
hence, slope of f(x) is -2
And slope of g(x) can be find by the formula
y= mx +c; where m is the slope on comparing the given equation with the above equation
We have slope of g(x) is -2
Hence, the slope of f(x) is the same as the slope of g(x).
Therefore, option A is correct.
What is the simplified form of the following expression? (n5)(n2)
Final answer:
The simplified form of the expression (n⁵)(n²) is found by adding the exponents since the base is the same, resulting in n⁷.
Explanation:
The simplified form of the expression (n⁵)(n²) is achieved by applying the laws of exponents. Since both terms have a common base of n, when multiplying two exponentials with the same base, we simply add their exponents.
The addition of 5 and 2 (the exponents) provides n⁵⁺² which simplifies to n⁷.
Hence, the simplified form of (n⁵)(n²) is n⁷.
