Answer:
(a) The closet to the simple interest eaened in 5 years is $275.00.
(b) The closet to the compound interest earned in 5 years is $276.28.
Step-by-step explanation:
These can be determine as follows:
(a) Simple Interest
The interest earned and be determined using the simple interest formula as follows:
Simple interest = P * R * T ....................... (1)
Where;
P = Principal = $1,000
R = interest rate = 5.5%
T = term = 5
Substituting the values into equation (1), we have:
Simple interest = $1,000 * 5.5% * 5 = $275.00
(b) Compound Interest
The interest earned and be determined using the compound interest formula as follows:
Compound interest = P(1 + R)^T - P ....................... (2)
Where;
P = Principal = $1,000
R = interest rate = 5%, or 0.05
T = term = 5
Substituting the values into equation (2), we have:
Compound interest = $1,000(1 + 0.05)^5 - $1,000 = ($1,000 * 1.05^5) - $1,000 = ($1,000 * 1.2762815625) - $1,000 =$1,276.28 - $1,000 = $276.28
Interest earned in savings Account 1 = 275
Interest earned in savings Account 2= 276.282
What is the difference between simple interest and compound interest?Simple interest is based on the principal amount of a loan or deposit. In contrast, compound interest is based on the principal amount and the interest that accumulates on it in every period.
interest earned by savings account 1
I₁=P*R*T/100
where,
P= Principal
R= rate of simple interest
T = time
I₁=1000*5.5*5/100
compound interest I₁=275
Interest earned by savings account2
amount A after n years= [tex]P(1+\frac{r}{100} )^n[/tex]
where,
A= amount received after 5 years
P= principal
r = rate(compound annually)
n = time
[tex]A = 1000(1+\frac{5}{100} )^5\\\\A=1276.282[/tex]
Compound interest I₂ = 1276.282-1000=276.282

The coach took a digital photo of the new cycling team bike. She sent a 4 cm-by-6 cm photo to each team
member.
1. If the photo were enlarged to 150% of its original size, what would be its new length (long side)?
9
2. Suppose you want to make a 2 cm-by-3 cm copy of the original photo.
What percent should you use?
50%
3. What will be the measurement for each angle in the smaller photo?
Answer:
1. 9 cm
2. 50%
3. Assuming the photo is a rectangle, the answer would be 90 degrees on every angle (in a dilation, angle measurements are congruent).
Step-by-step explanation:
1. The long side is clearly the 6 cm side. multiply it by 1.5x (150%) and you get 9.
2. 2 is 50% of 4 and 3 is 50% of 6.
3. Assuming the photo is a rectangle, the answer would be 90 degrees on every angle (in a dilation, angle measurements are congruent).
Lianne is saving to buy a DVD player that costs 2 1\2 times her weekly allowance. If she spends 3\4 of her allowance on other things, how long will she take to save the money for the DVD player?
Answer:
She will take 10 weeks to save the money for the DVD player
Step-by-step explanation:
Let w = Lianne's weekly allowance.
The DVD player costs 2 1/2 times her weekly allowance, thus
DVD cost = 5/2w
She gets w every week but spends 3/4w on other things, thus the remaining money is
Weekly savings =w - 3/4w = 1/4w
To know the number of weeks needed, we divide the DVD cost by the weekly savings:
[tex]\displaystyle N = \frac{\frac{5}{2}}{\frac{1}{4}}[/tex]
Operating:
[tex]\displaystyle N = \frac{5}{2}*\frac{4}{1}[/tex]
N = 10
She will take 10 weeks to save the money for the DVD player

Answer:
20789
Step-by-step explanation:
The equation of exponential growth is y=A(1+r)^t
A=10,000
r (rate)=0.05 (5% as a decimal)
t (time)=15 (2035-2020=15)

The library had 301 shelves of books. Each shelf had 13 books. Librarians checked out 807 books to students. How many books does the library have remaining
Answer:
3106 books
Step-by-step explanation:
From the question:
The library had 301 shelves of books. Each shelf had 13 books.
Hence, the total number of books in the library =
Number of shelves × Number rod books in a shelf
= 301 × 13 books
= 3913 books
The total number of books in the library is 3913 books
Librarians checked out 807 books to students.
How many books does the library have remaining?
This is calculated as:
Total number of books - Number of books checked out
= 3913 books - 807 books
= 3106 books
The library has 3106 books remaining.

Answer:
Inequality: 95 ≤ x ≤ 145
Minimum = 95
Maximum = 145
Step-by-step explanation:
Given
Budget = $120
Range = $25
Solving (a) Write an inequality to determine how much she could spend.
The range implies that she can spend less or more of the budgeted amount.
Let the amount to spend be represented by x.
If she spends more, the maximum would be
Max = Budget + Range
Max = 120 + 25
Max = 145
If she spends less, the minimum would be
Min = Budget - Range
Min = 120 - 25
Min = 95
So, this means that x could fall within the range of the minimum and the maximum.
Mathematically, this is:
Min ≤ x ≤ Max
So, the inequality would be:
95 ≤ x ≤ 145
Solving (b): The minimum and maximum.
The minimum and the maximum amount have been solved in (a) above.
Minimum = 95
Maximum = 145

Answer:
21x² +20x +100 = 0
Step-by-step explanation:
We know the sum of the roots of x² +bx +c = 0 is -b, and their product is c. If the roots are α and β, then ...
α+β = -bαβ = cThe sum of the roots of the new equation will be ...
-b' = (α+1/β)+(β+1/α) = (α+β) +(1/α +1/β) = (α+β)(1 +1/(αβ))
The product of the roots of the new equation will be ...
c' = (α+1/β)(β+1/α) = αβ +2 +1/(αβ)
Using the above relations for (α+β) and αβ, we find that ...
-b' = (-b)(1 +1/c)
c' = c + 2 + 1/c
For the given equation, our definition of b and c is ...
b = 2/3
c = 7/3
so the new equation has values ...
b' = (2/3)(1 + 1/(7/3) = (2/3)(10/7) = 20/21
c' = 7/3 + 2 + 1/(7/3) = 13/3 + 3/7 = 100/21
So, the equation with the roots of interest is ...
x² +20/21x +100/21 = 0
Multiplying by 21 gives ...
21x² +20x +100 = 0

A chemist has three different acid solutions. The first acid solution contains 15 % acid, the second contains 35 % and the third contains 65 % . He wants to use all three solutions to obtain a mixture of 72 liters containing 45 % acid, using 2 times as much of the 65 % solution as the 35 % solution. How many liters of each solution should be used?
Answer:
18 liters 15% acid
18 liters 35% acid
36 liters 65% acid
Step-by-step explanation:
Let's say x is the volume of 15% acid, y is the volume of 35% acid, and z is the volume of 65% acid.
x + y + z = 72
z = 2y
The amounts of acid add up to the final amount.
0.15x + 0.35y + 0.65z = 0.45 (72)
Substitute the expression for z into both equations.
x + y + 2y = 72
0.15x + 0.35y + 0.65 (2y) = 0.45 (72)
Simplify:
x + 3y = 72
0.15x + 1.65y = 32.4
Solve for x in the first equation, then substitute into the second.
x = 72 − 3y
0.15 (72 − 3y) + 1.65y = 32.4
Solve for y.
10.8 − 0.45y + 1.65y = 32.4
1.2y = 21.6
y = 18
Now find x and z.
x = 72 − 3y = 18
z = 2y = 36
18 liters 15% acid, 18 liters 35% acid and 36 liters 65% acid should be used.
What is percentage?Percentage is a measurement to find the value of a given number out of a hundred.
Let x is the volume of 15% acid, y is the volume of 35% acid, and z is the volume of 65% acid.
Given that, the total mixture is 72 liters,
Implies that,
x + y + z = 72
Also,65% solution is used two times as 35% solution is used.
z = 2y
The amounts of acid add up to the final amount.
0.15x + 0.35y + 0.65z = 0.45 (72)
Substitute the value of z here,
0.15x + 0.35y + 0.65 (2y) = 0.45 (72)
Simplify
x + 3y = 72
0.15x + 1.65y = 32.4
Solve for x in the first equation, then substitute into the second.
x = 72 − 3y
0.15 (72 − 3y) + 1.65y = 32.4
Solve for y.
10.8 − 0.45y + 1.65y = 32.4
1.2y = 21.6
y = 18
Now find x and z.
x = 72 − 3y = 18
z = 2y = 36
18 liters 15% acid, 18 liters 35% acid and 36 liters 65% acid should be used.
