Look at this check register. Calculate the current balance.
A check register has a balance of 82 dollars and 92 cents. 78 dollars and 24 cents is debited for a phone bill. 125 dollars is deposited for a pay check. 40 dollars is debited from the A T M. 56 dollars and 50 cents is debited for tennis lessons.
The current balance is $
.
Answer:
$33.18
Step-by-step explanation:
$33.18 is the answer because...
Step one first we have the money in the cash register of $82.92. Unfortunately she has to pay a phone bill of $78.24 so we subtract 82.92 and 78.24 which leaves the person with $4.68.Step two so she has $4.68 but now she gets an outstanding $125 paycheck. So we add $4.68 and $125 to get $129.68 as her new balance.Now the person's balance is $129.68 it says in the question she debited $40 from the ATM. So we subtract $129.68 and $40 to get $89.68.Step four she also had to pay $56.50 for the persons tennis lessons so we subtract $89.68 and $56.50 to get our final answer of $33.18Hope this helped :)The current balance is calculated by starting with the initial balance of $82.92 and then subtracting debits and adding credits from various transactions. After all adjustments, the current account balance is $33.18.
To calculate the current balance, we'll start with the first number under Balance and adjust it based on the recorded transactions.
Start with the initial balance: $82.92
Subtract the debit for the phone bill: $82.92 - $78.24 = $4.68
Add the deposit from the paycheck: $4.68 + $125.00 = $129.68
Subtract the ATM debit: $129.68 - $40.00 = $89.68
Finally, subtract the debit for tennis lessons: $89.68 - $56.50 = $33.18
Therefore, the current balance is $33.18.

a. How long does it take for each account to double?
b. How long does it take for each account to double again?
c. How does the growth in these two accounts compare? Explain your reasoning.
Help Me PLSSSSSSSSSSSSSSSS!!!!!!!!!!!!!!!!!!!!!!
Answer:
a. Account 1: 1 year Account 2: 10 years
b. Account 1: 2 years Account 2: 30 years
c. The first account grows exponentially, while the second one grows at a linear rate. Therefore, over time the first account tends to surpass the second one in value.
Step-by-step explanation:
The first account can be modeled by using a compounded formula with 100% rating, since it doubles every year. The formula is shown below:
M = C*(1 + r)^t
Where M is the final amount, C is the initial amount, r is the interest rate and t is the elapsed time. If r = 1, then it doubles every year, so we have the following expression for the first account:
M = 200*(2)^t
While the second acount grows at a steady rate of $100, therefore it can be modeled by the initial amount added by the growth rate multiplied by the elapsed time as shown below:
M = 1000 + 100*t
a. The first acount take 1 year to double, since it doubles every year.
In order for the second acount to double it needs to reach M = 2000, so we have:
2000 = 1000 + 100*t
100* t = 2000 - 1000
100*t = 1000
t = 10
It will take 10 years to double.
b. The first account will double again in 1 more year, so 2 years total.
The second account will need to reach M = 4000, therefore:
4000 = 1000 + 100*t
100*t = 4000 - 1000
100*t = 3000
t = 30
It'll take 30 years total for the second account to double again.
c. Since the first account grows exponentially it grows at a faster rate in comparison to the second one that grows linearly over time. Therefore over time the first account tends to surpass the second one in value.
In this exercise we will have to use the knowledge of finance to calculate the income time in this way we can say that:
a. [tex]Account 1: 1 year \\Account 2: 10 years[/tex]
b. [tex]Account 1: 2 years\\ Account 2: 30 years[/tex]
c. The first account grows exponentially, while the second one grows at a linear rate.
Then writing the yield formula as:
[tex]M = C*(1 + r)^t[/tex]
Where:
M is the final amountC is the initial amountr is the interest ratet is the elapsed timeIf r = 1, then it doubles every year, so we have the following expression for the first account:
[tex]M = 200*(2)^tM = 1000 + 100*t[/tex]
a. In order for the second acount to double it needs to reach M = 2000, so we have:
[tex]2000 = 1000 + 100*t100* t = 2000 - 1000100*t = 1000t = 10[/tex]
b. The second account will need to reach M = 4000, therefore:
[tex]4000 = 1000 + 100*t100*t = 4000 - 1000100*t = 3000t = 30[/tex]
c. Since the first record of finances evolve exponentially it become larger at a faster rate distinguished to the second individual that evolve linearly over opportunity. Therefore over opportunity the first fees be apt to outdo something or someone the second individual fashionable advantage.

What is the perimeter of the given composite figure
Answer:
The perimeter of the given composite figure is:
106 ydStep-by-step explanation:
The perimeter is defined as the sum of the sides in a figure, therefore, what you should do in this exercise is to add all the yards of the sides of the compound figure, however, you should notice that there are two sides of which They do not give you the measurement and you must identify it based on the sides that do have it, which would be:
Vertical line measurement = (19 + 4-17) yards Vertical line measurement = 6 yardsIn the previous case, the two measures on the other side that are complete are used, which are 19 yards and 4 yards respectively, then the measurement that is on our same side (17 yards) is subtracted and thus we obtain the value of the vertical line that it did not have, now that of the horizontal line:
Horizontal line measurement = (30-12-15) yards Horizontal line measurement = 3 yardsIn this case, something similar was done, the total measurement of the base was taken and the measurements of the upper zone were subtracted, with which the measurement of the remaining zone was found.
All the measures are added together:
The perimeter of the figure = 30 yd + 17 yd + 12 yd + 6 yd + 15 yd + 4 yd + 3 yd + 19 yd = 106 ydAnswer:

Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh where b is the base and h is the height
The base length is 6 and the height is 6
A = 1/2 (6) * 6
A =18
Answer:
B. 18 units²
Step-by-step explanation:
You find the area of the triangle with the dotted lines first:
[tex]\frac{1}{2}[/tex]*b*h
[tex]\frac{1}{2}[/tex]*9*6=
27
The area of the triangle including the dotted lines is 27 units²
Now we need to find the area of the small dotted triangle using the solid line triangle as a hypotenuse.
[tex]\frac{1}{2}[/tex]*b*h
[tex]\frac{1}{2}[/tex]*3*6=
9
The area of the small dotted triangle is 9 units²
To find the area of the solid lined triangle, you need to subtract the area of the small dotted line triangle (9 units²) from the triangle with the dotted lines (27 units²) which is:
27-9=18
The solid lined triangle is 18 units²

Answer:
0 ≤ x ≤ 4
Step-by-step explanation:
we are asked to find all the values of x such that y>0.
for y>0, this means that we will only consider the portion of the graph that is above the x - axis (i.e the part of the graph above y=0)
By observation, we can see that the graph is only above the x-axis between the interval 0 ≤ x ≤ 4 (which is the answer to your question)
What two numbers multiply together to get -42 and add up to be -1?
Answer:
-7 and 6
Step-by-step explanation:
You can solve this problem by setting up a system of equations. Lets call the first number x, and the second number y. Now:
x*y=-42
x+y=-1
You can subtract y from both sides of the second equation to get x=-y-1, which you can then substitute into the first:
(-y-1)*y=-42
-y^2-y=-42
y^2+y-42=0
Solving the quadratic equation:
(y-6)(y+7)=0
y=-7 or 6
x= 6 or -7
When one of the numbers is -7, the other is 6, and when it is 6, the other is -7. Hope this helps!

Given PQ | | ST
Triangle P Q R. Side P Q is 16 kilometers and side P R is 24 kilometers. Triangle S R T. Side R T is 33 kilometers.
What is the distance of Line S T?
7 km
StartFraction 128 Over 11 EndFraction km
22 km
49.5 km
The answer is C = 22km
Final answer:
To determine the distance of line ST, we use the fact that triangles PQR and SRT are similar, which allows us to set up a proportion with the given side lengths. Solving this proportion reveals that the length of ST is 22 kilometers.
Explanation:
To find the distance of line ST, we need to recognize that if lines PQ and ST are parallel (PQ | | ST) and we are given the lengths of the sides PQ and PR in triangle PQR and side RT in triangle SRT, we can infer that triangles PQR and SRT are similar by the Angle-Side-Angle (ASA) postulate since they share angle P (or R in triangle SRT) and have proportional corresponding sides.
Using the lengths PQ = 16 kilometers and PR = 24 kilometers from triangle PQR and RT = 33 kilometers from triangle SRT, we can set up a proportion to solve for the unknown length ST.
The proportion based on the similarity of triangles is:
PQ/PR = ST/RT
Substituting the given values, we get:
16/24 = ST/33
Solving for ST, we multiply both sides by 33:
ST = 33 * (16/24) = 22 kilometers.
Therefore, the distance of line ST is 22 kilometers.
Pentagon VWXYZ is shown on the coordinate grid. A student reflected pentagon VWXYZ across the y-axis to create pentagon V'W'X'Y'Z'. Which rule describes this transformation? *
(x, y) --> (-x , y)
(x, y) --> (x , y + 8)
(x, y) --> (-y , x)
(x, y) --> (x , -y)
Answer: (x, y) —> (-x, y)
Step-by-step explanation:
This is because the translation rule for reflection across the y-axis is (x, y) —> (-x, y)
(x, y) --> (-x , y)
Step-by-step explanation:
When reflecting across the y-axis, you will want to switch the sign of the x-coordinate. If the x-coordinate is positive, you will want to switch it to negative and vice versa.
Examples:
(3,5) --> (-3,5)
(-6,-2) --> (6,-2)
~
If you are going to reflect across the x-axis, you will change the y-coordinate, so it is the opposite of reflecting across the y-axis.
Identify the correct formula for the following sequence. 2, -4, -10, -16, -22, ...
A. an = 6n - 8
B. an = -8n + 6
C. an = 8n - 6
D. an = -6n + 8
Answer:
D
Step-by-step explanation:
The terms in the sequence have a common difference d between consecutive terms, that is
d = - 4 - 2 = - 10 - ( - 4) = - 16 - (- 10) = - 22 - (- 16) = - 6
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 2 and d = - 6, thus
[tex]a_{n}[/tex] = 2 - 6(n - 1) = 2 - 6n + 6 = - 6n + 8 → D
