ending balance 1 59.75 outstanding deposits 175 .46 outstanding checks 231 .69 what is the balance
To calculate the balance, add the outstanding deposits to the ending balance and subtract the outstanding checks.
Explanation:To calculate the balance, we need to start with the ending balance and make adjustments for outstanding deposits and outstanding checks. First, add the outstanding deposits to the ending balance: 59.75 + 175.46 = 235.21. Next, subtract the outstanding checks from the previous result: 235.21 - 231.69 = 3.52. Therefore, the balance is $3.52.

Which graph represents a linear function?
A coordinate plane is shown with a curved line that starts in the bottom left area of the graph, passing through the point -1 comma -5, curving to pass through the y-axis at 2.5, then curving up again to pass through the point 1 comma 5
A coordinate plane is shown with a line passing through the x-axis at negative 2 and the y-axis at negative 6.
A coordinate plane is shown with a parabola graphed in an upward U shape. The bottom of the parabola touches the y-axis at -10 and curves upward on both sides
A coordinate plane is shown with a wavy line that sits on the x-axis and moves across the graph in even up and down waves.
Answer:
2nd Option is correct.
Step-by-step explanation:
We are given with four statements which describes a graph of a function.
We need to find the graph which represents the linear function.
Linear Function:
Linear functions are the functions whose graph are straight lines.
A linear function has the following form
y = f(x) = a + bx
A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.
So, In graphs of 1st , 3rd and 4th Options are curves not a straight line.
Only 2nd Option has graph which is straight as mentioned in it that a line passing through two points.
Therefore, 2nd Option is correct.
Write a linear equation in slope intercept form to model a tree 4 feet tall the grows 3 inches per year
The linear equation that models the growth of a tree that is 4 feet tall and grows 3 inches per year is y = 3x + 48.
Explanation:The problem involves writing a linear equation in slope-intercept form to model the growth of a tree. The slope-intercept form is given by the equation y = mx + b, where 'm' represents the slope or the rate of change, and 'b' is the y-intercept or the initial value.
In the context of this problem, the tree's initial height is 4 feet and it grows at a rate of 3 inches per year. However, the units of the initial height and the yearly growth rate are different, so we need to convert 4 feet into inches. As 1 foot is equivalent to 12 inches, the initial height of the tree is 4 * 12 = 48 inches.
Therefore, the slope or rate of change 'm' is 3 inches per year and the y-intercept or initial value 'b' is 48 inches. Substituting these values into y = mx + b gives us the linear equation representing the growth of the tree: y = 3x + 48.

1/5 (7-3b) > 2
which of the following gives all values of b that satisfy the inequality above?
A) b< -1
B) b> -1
C) b< 1
D) b> 1
The value of b that satisfy the inequality are; B) b> -1 and C) b< 1
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
We have given an inequality;
1/5 (7-3b) > 2
To solve for b;
(7-3b) = 10
-3b = 10 - 7
-3b = 3
b = -3/3
b = -1
Thus, the value of b that satisfy the inequality are; B) b> -1 and C) b< 1

The correct solution for the given inequality 1/5 (7-3b) > 2 gives us b < -1. Option A is correct.
The given inequality is 1/5 (7-3b) > 2. To find the range of values for b that satisfy this inequality, follow these steps:
Multiply both sides of the inequality by 5 to eliminate the fraction: 7 - 3b > 10.
Subtract 7 from both sides of the inequality: -3b > 3.
Since we are dividing by a negative number, remember to reverse the inequality sign: b < -1.
Therefore, the correct answer is b < -1, which is option A.
What is the r value of the following geometric sequence? 4, 7, 12.25, 21.4375.
Answer:
r ( common ratio) = 1.75
Step-by-step explanation:
Given : geometric sequence 4, 7, 12.25, 21.4375.
To find : What is the r value .
Solution : We have given
Geometric sequence 4, 7, 12.25, 21.4375.
r ( common ratio) = [tex]\frac{second\ term}{first\ term}[/tex].
r ( common ratio) = [tex]\frac{7}{4}[/tex] = 1.75
r ( common ratio) = [tex]\frac{12.25}{7}[/tex] = 1.75
Therefore, r ( common ratio) = 1.75

Isabella paid one of her bill late and owed a 4% late fee was 780. How much was Isabella's original bill in dollar
The original bill amount that Isabella owed before the late fee was $19,500.
We need to understand the relationship between the late fee and the original bill amount.
Isabella was charged a late fee of 4% of the original bill amount, and this late fee was $780.
Let's use the variable x to represent the original bill amount. Since the late fee is 4% of the original bill, we can write the equation:
[tex]0.04x = 780[/tex]
To find x, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 0.04:
[tex]x = \frac{780}{0.04}[/tex]
Now, we can calculate this value:
[tex]x = 19500[/tex]

In rectangle ABCD, BC=30 and AB=40. If diagonals AC and BD intersect at E, find the measure of BE.
To find the measure of BE in rectangle ABCD, we can use the properties of a rectangle and similar triangles. By using the Pythagorean theorem, we find the length of the diagonal AC. Then, we use the properties of similar triangles to calculate the length of BE.
Explanation:To find the measure of BE, we can use the properties of a rectangle. In rectangle ABCD, the diagonals are equal in length and bisect each other. Therefore, we can use the Pythagorean theorem to find the length of the diagonal AC: AC^2 = AB^2 + BC^2. Plugging in the values given, AC^2 = 40^2 + 30^2 = 2500, so AC = sqrt(2500) = 50. Since the diagonals bisect each other, we can conclude that AE = 50/2 = 25. Now, we can use the properties of similar triangles to find the length of BE. Triangle ABE is similar to triangle ACE, so we can set up the following proportion: AB/AC = BE/AE. Plugging in the values, 40/50 = BE/25. Solving for BE, we get BE = (40/50) * 25 = 20.
To find the measure of BE in rectangle ABCD, we use the Pythagorean Theorem. As the diagonals bisect each other, BE is half the length of diagonal AC, resulting in BE = 25.
Explanation:In rectangle ABCD with BC=30 and AB=40, the diagonals bisect each other. That means E, the point of intersection, is the midpoint of both diagonals AC and BD. Since ABCD is a rectangle, its diagonals are equal, and AC = BD. To find BD, we use the Pythagorean Theorem in ΔABC:
AC² = AB² + BC²AC² = 40² + 30²AC² = 1600 + 900AC² = 2500AC = √2500AC = 50Since E is the midpoint of BD, BE is half the length of BD:
BE = BD/2BE = AC/2 (because AC = BD)BE = 50/2BE = 25
