Using the compound interest formula, the "n" is what value when compounded annually?
Answer:
n=1
Step-by-step explanation:
N is the number of times per year
Annually would be one time per year so n =1
Answer:
If interest is compounded yearly, then n = 1; if semi-annually, then n = 2; quarterly, then n = 4; monthly, then n = 12; weekly, then n = 52; daily, then n = 365; and so forth, regardless of the number of years involved. Also, "t" must be expressed in years, because interest rates are expressed that way.

Mona needs to photocopy a 14.5 centimeters wide by 15 centimeters long picture. She wants to enlarge the picture so that its length will be
37.5 centimeters. How wide will the enlarged picture be?
O a
38.8 cm
Ob
37 cm
ос
93.75 cm
Od
36.25 cm
Answer:
The enlarged picture will have a width of 35.8 cm
Step-by-step explanation:
We can solve this question by proportions, using rule of three.
When the length is of 15 centimeters, the width will be of 14.5 centimeters. What is the width when the length is 37 centimeters?
15 cm - 14.5 cm
37 cm - x
Applying cross multiplication
[tex]15x = 14.5*37[/tex]
[tex]x = \frac{14.5*37}{15}[/tex]
[tex]x = 35.8[/tex]
The enlarged picture will have a width of 35.8 cm
Answer:
36.25 cm
Step-by-step explanation:
37.5 divided by 15 is 2.5 then multiply 14.5 by 2.5 and your answer will be 36.25 cm.

solve the inequality 2(n+3) - 4 < 6. then graph the solution.
Please help ??
Answer:
n < 2
Step-by-step explanation:
Answer: Look at the explanation please.
Step-by-step explanation:
The first thing you would do is distribute the 2 to the n and the 3.
You will then get 2n+6-4<6
Next, you will have to subtract 6-4 and you will get 2
You will the have 2n+2<6
Subtract 2 from 2 to get 0 and from 6 to get 4.
Your left with 2n<4
Then, divide 2 from 2n and 2 from 4
Last, your answer will be n<2.
Graphing
Your graph would look like (from what I see in my book)
You have seven tick marks and in the middle will be 0.
From the left of 0 should have negative 1, 2, and 3
From the right of 0 would be positive 1, 2, and 3
On the top of 2 would be a open circle and an arrow going to the left.

One year ago, Lindsey deposited $250 into a savings
account. Her balance
deposited $250 into
now $253, Two years ago, Jenn
savings account Her balance is
now $257.50. Which account has the greater simple
interest rate? Explain,
Answer:
Jenns account has the greater simple interest rate.
Step-by-step explanation:
The formula for simple interest is:
A = P * ( 1 + r * t )
Where A is the final amount after investment, P is the initial amount, r is the rate of interest and t is the time periods.
For Lindsey:
253 = 250 * ( 1 + r * t )
Solve for r
r = ( 253/250 ) - 1 = 0.012
Lindsey simple interest was 1.2% annually
For Jenn:
257.50 = 250 * ( 1 + r * 2 )
r = ( 257.50/250 ) - 1 )/2 = 0.015
Jenn simple interest was 1.5% annually
Therefore Jenns account has the highest simple interest rate.
Answer:
Lindsay’s interest is $3 for one year. Using the formula for interest, I = prt, Lindsey’s money is earning at a rate of 1.2%. Jenn has earned $3.75 for one year. Her money is earning at a rate of 1.5%, which is a higher interest rate.

30 kilograms of beans costs $5. How many kilograms of beans can you buy for $20?
Answer:
120 kg
the kilograms of beans which can by for $20 are
30*(20/5) = 30.4 = 120 (kg)
Answer: 120 kilograms
Step-by-step explanation:
We can buy 30 kilograms of beans for $5 dollars. We need to find how many kilograms of beans we can buy for $20.
The first step is to divide 20 by 5. Then, using the quotient, we can multiply it by 30 to see how many kilograms of beans we can buy for $20.
20 ÷ 5 = 4.
4 x 30 = 120.
Therefore, we can buy 120 kilograms of beans for $20.
Cool beans ;)

The linear factors of the given polynomial are (2x+3)(x+1)(x+2+i)(x+2-i)
What is linear factor?The linear factors of polynomials are the first-degree equations that act as the building block for the simple or complex higher-order polynomials.
Given that, a polynomial 2x⁴+13³+27x²+13x-15, the remainder upon division with x²+4x +5 is zero,
That means, x²+4x +5 is a factor of the given polynomial,
On diving 2x⁴+13³+27x²+13x-15 by x²+4x +5 we get 2x²+5x+3 as quotient that means, x²+4x +5 and 2x²+5x+3 are the factors of the polynomial,
On factorizing both the factors we get,
(2x+3)(x+1)(x+2+i)(x+2-i)
Hence, the linear factors of the given polynomial are (2x+3)(x+1)(x+2+i)(x+2-i)
