a bank offers two different types of interest on saving accounts
account 1 pays 5.5 % simple interest
account 2 pays 5% interest compounded annually
deposits of 1000 are made into the accounts of each type. no additional Including
withdraws or deposits are made.
what amount is the closest to the interest earned in 5 years.
Answers
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
Therefore,
interest earned in savings Account 1 = 275
interest earned in savings Account 2= 276.282

b. 7x + 2.8y
Step-by-step explanation:
distribute the negative sign:
= -2x + 8.1 + -1(-9x + 5.3y)
= -2x + 8.1 + -1(-9x) + -1(5.3y)
= -2x + 8.1 +9x + -5.3y
combine like terms:
= (-2x + 9x) + (8.1 + -5.3y)

Un delfinariu are un bazin in forma de cilindru cilcular drept. Pentru a oferi mai multe reprezentati, bazinul este impartit in doua parti egale printr un perete dreptunghiular cu aria de 300 m patrati. Se stie ca raza bazei cilindrullui este de 15 m. Aflati inaltimea bazinului.
Answers
Answer:
Înălțimea bazinului este de 20 m
Step-by-step explanation:
Raza de bază a bazinului cilindric = lățimea peretelui dreptunghiular = 15 m
Suprafața peretelui dreptunghiular = lungime × lățime = 300 m²
300 m² = lungime × 15 m
lungime = 300 m² / 15m
lungime = 20 m
Lungimea peretelui dreptunghiular = înălțimea bazinului cilindric = 20 m
Prin urmare, înălțimea bazinului = 20 m.
Consider the equation 3a+0.1n=123. If we solve this equation for n, which equation would result? A. 0.1n=123-3a B. N=123-3a-0.1 C.N=1,230-30a D. 3a-123 over 0.1 =n
Answers
Answer:
n = (123 - 3a) / 0.1
Step-by-step explanation:
Given:
3a + 0.1n = 123
Solve for n
3a + 0.1n = 123
Subtract 3a from both sides
3a + 0.1n - 3a = 123 - 3a
0.1n = 123 - 3a
Divide both sides by 0.1
n = (123 - 3a) / 0.1
The resulting equation if 3a + 0.1n = 123 is solved for n is n = (123 - 3a) / 0.1

A tanker truck fills the gas station’s reservoir at the rate of 12 1/2 gallons per minute.
If the reservoir was empty and it is now 35 gallons full, how long has the tanker been filling the reservoir?
Answers
Answer: 2.8 minutes
Step-by-step explanation:
If it takes 12.5 gallons per minutes to fill the reservoir, then we have to divide 35 and 12.5.
35 ÷ 12.5 = 2.8 minutes
Since it takes 12.5 gallons per minutes to fill the reservoir, it will take 2.8 minutes to fill the reservoir.

Which statement correctly identifies the mistake Joe made? in step 5, Joe should have added 1 to both sides of the equation instead of dividing both sides of the equation by --1. In step 2. Joe should have multiplied the first equation by 2 instead of by 3. in step 4, Joe simplified 27 + (-20) as 7 instead of simplifying to -7. In step 3, Joe multiplied the term -2y by 2 instead of by-2.
Answers
Answer:
This question is incomplete as it lacks the actual question. The question describes how Joe solved a system of equations step-by-step using elimination method. The steps used by Joe are as follows:
1. The equations given are: 2x + y = 9 and 3x - 2y = 10.
2. Multiply the first equation by 3 to get 6x + 3y = 27
3. Multiply the second equation by -2 to get -6x - 4y = -20
4. Add the equations to get -y = 7
5. Divide both sides of the equation by -1 to get y = -7
The statement that correctly identifies the mistake Joe made is: In step 3, Joe multiplied the term -2y by 2 instead of by-2.
Step-by-step explanation:
Elimination method of solving a simultaneous equation in Mathematics involves removing one variable in order to solve another variable. In this case of equations:
2x + y = 9
3x - 2y = 10
Joe eliminates the x variable in order to solve for the y variable first. To do this;
- In step 2, he correctly multiplies the first equation by 3 to get 6x + 3y = 27
- In step 3, he multiplies the second equation by -2 to INCORRECTLY get -6x - 4y = -20
Joe made a mistake in this step 3 because he multiplied -2y in the original equation (3x - 2y = 10) by 2 and not -2. He should have gotten -6x + 4y = -20 if he multiplied by (-2). That is (-2 × -2y) to give +4y.
What is the weight of the seawater in an aquarium that is 4.4 ft long, 2.5 ft wide, and 5.3 ft high?
Answers
Answer:
The weight of the sea water in the aquarium is 3827.119 lb
Step-by-step explanation:
We start by calculating the volume of the aquarium
Since it is a cuboid, the volume will be L * B * H
= 4.4 * 2.5 * 5.3 = 58.3 ft^3
Mathematically;
Mass = density * volume
The density of sea water is 63.93 lb/ft^3
Mass = 63,93 * 58.3 = 3,827.119 lb
The ratio of women to men working at a grocery store is 4 to 5. There are 16 women working at the store . What is the total number of people working at a grocery store?
Answers
Answer:
36 people
Step-by-step explanation:
The ratio of women to men working at a grocery store is 4 to 5.
The ratio =
Women : Men
4 : 5
The sum of the proportion is 4 + 5 = 9
There are 16 women working at the store .
Let us represent the total number of people working at a grocery store as x
Hence:
4/9 of x = 16 women
4/9 × x = 16
4x/9 = 16
Cross Multiply
4x = 16 × 9
x = 16 × 9/4
x = 36 people
The total number of people working in the grocery store is 36 people
In the year 2000, the United States had about 100,300,000 people registered to use cellular phones. How would this number of people be written in scientific notation?
Answers
Answer:
1.003 * 10^8
Step-by-step explanation:
Given that :
The United States has about 100,300,000 registered to use cellular phones in the year 2000
100,300,000 in scientific notation:
(100,000,000) + (300,000)
(1 * 10^8) + (3 * 10^5)
To ensure equal power :
300,000 = 3 * 10^5 = 0.003 * 10^8
Hence,
(1 * 10^8) + (0.003 * 10^8)
(1 + 0.003) * 10^8
1.003 * 10^8
