Answer:
Option B. $878.28
Step-by-step explanation:
On Monday, Elsbeth's bank account balance was = $-16.75
She deposited a check = $5.72
On Thursday, she deposited = $16.75
Her new balance = -16.75+( 5.72 + 16.75)
= $5.72
On Friday Elsbeth deposited her pay check for = $872.56
The account's final total = 872.56 + 5.72 = $878.28
Elsbeth's account's final total was $878.28.
Option B. $878.28.
What’s the measure of LMF
LMF = 17x
so 17x + 3x =180
20x = 180
x = 180/20 = 9
17 *9 = 153
angle LMF = 153 degrees
The prime factorization of a number n can be written as n=pr whose p and r are distinct primes. how many factors does n have not including 1.
The total number of factors for a number 'n' with prime factorization [tex]n = p^r * q^s * ... * z^w[/tex] (where 'p', 'q', ..., 'z' are distinct primes and 'r', 's', ..., 'w' are their respective powers) is equal to (r + 1) * (s + 1) * ... * (w + 1).
When we have the prime factorization of a number, determining its total number of factors is a straightforward process. The number of factors of 'n' can be found by considering the powers of its prime factors.
Let's take an example to illustrate this. Consider the number 'n' with prime factorization:
[tex]n = p^r * q^s * ... * z^w,[/tex]
where 'p', 'q', ..., 'z' are distinct prime numbers, and 'r', 's', ..., 'w' are their respective powers.
To find the total number of factors for 'n', we need to consider all possible combinations of its prime factors. For any factor of 'n', we can choose to include 'p' raised to a power ranging from 0 to 'r', 'q' raised to a power ranging from 0 to 's', and so on, for all the distinct primes.
The total number of factors can be calculated using the formula:
(r + 1) * (s + 1) * ... * (w + 1)
This formula works because for each prime factor 'p', we have 'r + 1' options for its power, and similarly for other prime factors. By multiplying all these options, we get the total number of factors.

violet chewed 5 times as many pieces of bubble gum in one week as her friend if her friend chewed 12 pieces of bubble gum.how many did violet chew
Violet chewed 60 pieces of bubble gum in one week.
Explanation:To find out how many pieces of bubble gum Violet chewed, we need to multiply the number of pieces that her friend chewed by 5. Her friend chewed 12 pieces of bubble gum, so we can multiply 12 by 5.
12 x 5 = 60
Therefore, Violet chewed 60 pieces of bubble gum in one week.

Answer: 27[tex]\pi[/tex] [tex]unit^{2}[/tex]
Step-by-step explanation: area of circle =[tex]\pi r^{2}[/tex]
where r is the radius of circle
here r=9
to find the area of circle we cover an angle of 360° but here we have to cover only 120°=360°÷3
so area of shaded region =area of circle÷3

Which property justifies this statement?If x=−2, then 5x=−10.
A.Multiplication Property of Equality
B.Transitive Property of Equality
C.Symmetric Property of Equality
D.Subtraction Property of Equality
Answer:
Correct option is:
A.Multiplication Property of Equality
Step-by-step explanation:
The Multiplication Property of Equality states that if you multiply both sides of an equation by the same number, the sides remain equal (i.e. equality is preserved).
Here, we are given a equality:
x= -2
Now, on multiplying both sides by 5, the equality will be preserved
i.e. 5x= -2×5
i.e. 5x= -10
Hence, Correct option is:
A.Multiplication Property of Equality
The property of equality that justifies the given statement is the Multiplication Property of Equality
The correct option is A.Multiplication Property of Equality
From the question, we have that
If x=−2, then 5x=−10
The property of equality that justifies this statement is the Multiplication Property of Equality.
This is because, when both sides of the first equation is multiplied by 5, the result gives the other equation.
That is,
[tex]5 \times x = -2 \times 5[/tex], yields
5x=−10.
Hence, the property of equality that justifies this statement is the Multiplication Property of Equality

Why are two lines with the same y intercept are perpendicular?
Two lines with the same y-intercept are perpendicular because they are only perpendicular if their slopes are the reciprocals of each other's negative values.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
The standard form of the lines are:
y = mx + c
Here m is the slope and c is the y-intercept of the line
mM = -1
The M is the slope of the second line which is perpendicular to the first one.
y = Mx + c (with the same y-intercept)
Thus, two lines with the same y-intercept are perpendicular because they are only perpendicular if their slopes are the reciprocals of each other's negative values.
