Step 1: Let's review the information given to us to answer the problem correctly:
• p = Principal
,• 0.12 = Interest rate
,• 224 = Future value
Step 2: Let's write a problem based on this information, using the Simple Interest Formula, as follows:
A = P(1 + rt), where:
A = Final amount
P = Principal
r = Annual interest rate
t = Time in years
224 = P (1 + 0.12t)
224 = 1.12Pt
Pt = 224/1.12
Pt = 200
If P = 200, then t = 1
Step 3: Let's interpret the answer and the problem we just wrote.
What is the amount of principal and the time of deposit for a savings account that earns 12% annually, and shows a final balance of $ 224?
Answer: $ 200 and the period of time is 1 year.

ANSWER
150 + 10n
EXPLANATION
We want to simplify:
10(15 + n)
To do this, we have to use the distributive property:
a(b + c) = a*b + a*c
Therefore:
10(15 + n) = (10 * 15) + (10 * n)
= 150 + 10n

Answer:
We will use the following identities:
[tex]\begin{gathered} \csc (x)=\frac{1}{\sin (x)} \\ \cot (x)=\frac{\cos (x)}{\sin (x)} \end{gathered}[/tex]So, replacing the identities on the left side, we get:
[tex]\frac{1+\csc^2(x)}{\cot^2(x)+1}=\frac{1+(\frac{1}{\sin(x)})^2}{(\frac{\cos (x)}{\sin (x)})^2+1}[/tex]Then, solving the power and adding the expressions, we get:
[tex]\frac{1+csc^2(x)}{\cot^2(x)+1}=\frac{1+\frac{1}{\sin^2(x)}}{\frac{\cos^2(x)}{\sin^2(x)}+1}[/tex][tex]\frac{1+csc^2(x)}{\cot^2(x)+1}=\frac{\frac{\sin^2(x)+1}{\sin^2(x)}}{\frac{\cos ^2(x)+\sin ^2(x)}{\sin ^2(x)}}[/tex]Dividing the expression and simplifying, we get:
[tex]\frac{1+csc^2(x)}{\cot^2(x)+1}=\frac{\sin ^2(x)+1}{\cos ^2(x)+\sin ^2(x)}[/tex]Finally, we know that cos²(x) + sin²(x) = 1, so we can rewrite the expression as:
[tex]\begin{gathered} \frac{1+\csc^2(x)}{\cot^2(x)+1}=\frac{\sin ^2(x)+1}{1} \\ \frac{1+\csc^2(x)}{\cot^2(x)+1}=\sin ^2(x)+1 \end{gathered}[/tex]The table below shows that 1 day equals 24 hours. Notice that 12 hours is one-half of that. Use the table to help you determine how many days are equal to 30 hours. 1 day 24 hours 12 hours 12 hours (3 points) a 1 and 1 over 4. days b 1 and 1 over 2. days c 1 and 3 over 4. days d 2 days
54 hours is equivalent to 2 and 1 over 4 days. Because 1 day has 24 hours so we have to divide 54/24 to get the numeral of days which is equal to 2.25 days and .25 is equivalent to 1/4 of a day i.e., 2 1/4 days.
How is math operated in time?Time math entails learning how to tell time and converting it into seconds, minutes, hours, days, weeks, months, and years. Finding time math solutions can involve adding and subtracting to determine the amount of time elapsed or multiplying or dividing to convert time units. Time can be defined in mathematics as an ongoing and continuous sequence of events that occur in succession, from the past to the present to the future. Time is used to quantify, measure, compare, and even sequence events. Atomic clocks provide the most accurate measurement of time intervals the duration between two events. These clocks emit electromagnetic radiation, such as microwaves, at a precise frequency that causes the clock's atoms to jump from one energy level to another.

Answer:
The slopes are the same and the y-intercepts are different.
Explanation:
Given:
[tex]\begin{gathered} x+2y=8 \\ 2x+4y=12 \end{gathered}[/tex]Recall that the slope-intercept equation of a line is generally given as;
[tex]y=mx+b[/tex]where;
m = slope of the line
b = y-intercept of the line
Let's go ahead and rewrite the first equation in slope-intercept form as seen below;
[tex]\begin{gathered} x+2y=8 \\ 2y=-x+8 \\ y=-\frac{1}{2}x+\frac{8}{2} \\ y=-\frac{1}{2}x+4 \end{gathered}[/tex]We can see from the above that the slope(m) of the first equation is -1/2 and the y-intercept(b) is 4.
Let's go ahead and rewrite the second equation in slope-intercept form as seen below;
[tex]\begin{gathered} 2x+4y=12 \\ 4y=-2x+12 \\ y=-\frac{2}{4}x+\frac{12}{4} \\ y=-\frac{1}{2}x+3 \end{gathered}[/tex]We can see from the above that the slope(m) of the second equation is -1/2 and the y-intercept(b) is 3.
We can see from the above that, for the two equations, the slopes are the same, and the y-intercepts are different.

your checking account is overdrawn by $120.22. you write a check for $80.25. what is the balance in your account???
The amount or balance left in the bank account is $39.97.
The amount of money held in a financial institution, such as a savings or checking account, at any particular time is known as the account balance. The net amount, which includes all debits and credits, is always the account balance.
The current balance in the bank account is $120.22.
The check was issued for $80.25.
Let x be the balance left in the account.
Then,
The balance left = Initial balance in the account - The amount for which the check was issued

The measures of the unknown angles are as follows:
∠1 = 27∠2 = 97°∠3 = 56°∠4 = 27°∠5 = 56°How to find the measures of angles?When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate angles, linear angles etc.
The parallel lines are line m and line l . The parallel lines m and l are cut by two transversals.
Therefore, the measures of the unknown angles are as follows:
∠1 = 27°(vertically opposite angles)
∠1 = ∠4(alternate angles)
∠4 = 27°
Alternate angles are congruent. Vertically opposite angles are congruent.
Therefore,
∠1 + ∠2 = 124
27 + ∠2 = 124
∠2 = 124 - 27
∠2 = 97°
∠3 = 180 - ∠2 - ∠1 (sum of angles on a straight line)
∠3 = 180 - 97 - 27
∠3 = 56°
∠5 = 180 - ∠4 - ∠2
∠5 = 180 - 97 - 27

His bedroom is a rectangle with length 5m and width 4m. He decides on a scale of 1 to 80.
The scale drawing with length 0.0625m and width 0.05m.
What is scale factor?To adjust the size of a figure without altering its shape, a scale factor is a number or conversion factor that is utilised. It is employed to change the size of an object.
When both the original dimensions and the new dimensions are known, the scale factor may be determined. When employing the scale factor, there are two terms that must be understood. When a figure's size is increased, we refer to this as scaling up, and when its size is decreased, we refer to this as scaling down.
Given:
length= 5m
width= 4m
and,
The scaled dimension = (Actual dimension) x (scale factor) ...(i)
scale factor =1/50
(1) The actual width = 4 m.
So, the width of the door on the scale drawing= 4x (1/80)= 0.05 m
(2)The actual length = 5 m.
So, the length of the door on the scale drawing= 5 x (1/80)= 0.0625 m
Hence, the scale drawing with length 0.0625m and width 0.05m.

Singer A and Singer B had the two top-grossing concert tours for a certain year, together generating $438 million in ticket sales. If Singer B took in $22 million less than Singer A, how much did each tour generate?
To answer this question, we have that both singers generated $438 million in tickets sales.
Then, we can rewrite it in algebraic expressions as follows:
[tex]A+B=438[/tex]However, we know that singer B took in $22 million less than singer A:
[tex]B=A-22[/tex]Now, we can substitute this expression in the original one as follows:
[tex]A+A-22=438[/tex]And to solve this equation, we can add the like terms, and then add 22 to both sides of the equation as follows:
[tex]2A-22+22=438+22\Rightarrow2A=460\Rightarrow\frac{2A}{2}=\frac{460}{2}[/tex][tex]A=230[/tex]Then, to find the earnings of singer B, we have:
[tex]A+B=438\Rightarrow B=438-A[/tex]Then, B is equal to:
[tex]B=438-230\Rightarrow B=208[/tex]Then, we can check that A + B is:
[tex]A+B=230+208=438[/tex]And we can see that singer B took in $22 million less than singer A:
[tex]B=230-22=208[/tex]In summary, therefore, we can say that each tour generated:
Singer A generated $230 million in ticket sales and Singer B generated $208 million.

Let's follow the steps shown to find out the step with the error.
Step 1:
Multiply equation 1 by -4
-4(m) = -4(8 + 2n)
4m = 4 + 4n
Step 2:
