Problem
You deposit $2000 into a bank account paying 4.5% simple interest per year. You left the money in for 8 years. How much interest do you get at the end of those 8 years?
Result
The interest is $720.
Then you add the money you invested to your interest so your answer would be ' C ',
I think I'm not that great with math but I really hope I helped you .
Answer:
D. $2630
Step-by-step explanation:
Given,
The principal amount, P = $ 2000,
Annual rate of interest, r = 4.5 % ,
Thus, the interest for 7 years,
[tex]I=\frac{P\times r\times 7}{100}[/tex]
[tex]=\frac{2000\times 4.5\times 7}{100}[/tex]
[tex]=\frac{63000}{100}[/tex]
[tex]=630[/tex]
Hence, the amount after 7 years or at the beginning of the 8th year is,
[tex]A=P+I=2000+630=\$ 2630[/tex]
Option 'D' is correct.
The highest point in the United States is Mount McKinley in Alaska. Its summit is 20,335 feet above sea level. Badwater, a basin located in Death Valley, is the lowest point in the United States at 282 feet below sea level. How high is the summit of Denali above the Death Valley location? (How far apart are the two distances?) *
Answer:
20,053
Step-by-step explanation:
20,335 - 282 = 20,053
Answer:
20617 feet is your answer
Step-by-step explanation:
You are subtracting the two numbers. Note however, that 282 feet below the sea level = -282
Subtract.
20335 - (-282) = answer
Note that two negatives = one positive

Arrange the steps in order to solve this expression sin (3pi/4) cos (pi/12)
To solve sin (3\u03c0/4) cos (\u03c0/12), calculate the value of sin (3\u03c0/4), use the half-angle formula to find cos (\u03c0/12), and multiply the results.
Explanation:To solve the expression sin (3\u03c0/4) cos (\u03c0/12), we need to find the sine and cosine values of the individual angles and then multiply them together. The sine of 3\u03c0/4 is \u221a2/2 and the cosine of \u03c0/12, which is not a standard angle on the unit circle, can be calculated using the half-angle formula since \u03c0/12 is half of \u03c0/6. Therefore, once we have both values, we simply multiply them to get the result of the expression.

10. You are finding 3% of 100, or .03 x 100. The product should be 3.
11. You are finding the whole amount of 3, or 1 x 3. The product should be 3.
12. Again, find 80% of 120, or 0.80 x 120. The product should be 96.
13. This time, because the number is greater than 100%, you would write it as 1.15 x 6. The answer should be 6.90.
14. In this scenario you are going backwards--meaning instead of using multiplication you use division. If 32 is the amount inside of 128, you divide 32 by 128. The quotient should be 0.25, or 25%.
15. Just like #14 (except phrased differently), 3 is inside of 36, so you divide 3 by 36. The quotient should be 0.08333... or about 8%.
16. In this problem you will have to divide again, except (because the decimal is given) you divide the amount left, 23.7, by the decimal/percent, .30. The quotient should be 79.

In a recent year a baseball team paid two times as much to their ace pitcher as they paid to their shortstop. If they paid $21 million for the two salaries, what did they pay each player?
The ace pitcher was paid $14 million and the shortstop was paid $7 million.
Explanation:In order to solve this problem, we can set up a system of equations. Let's say the salary of the ace pitcher is x million dollars and the salary of the shortstop is y million dollars. We are given that the ace pitcher was paid twice as much as the shortstop, so we can set up the equation x = 2y.
We also know that the total salaries paid were $21 million, so we can set up the equation
x + y = 21.
Using the first equation, we can substitute 2y for x in the second equation to get 2y + y = 21, which simplifies to 3y = 21. Dividing both sides by 3, we find that y = 7 million.
Substituting this value back into the first equation, we find that x = 2(7) = 14 million.
Therefore, the ace pitcher was paid $14 million and the shortstop was paid $7 million.

53x4 estimate of product Then record the product
Estimate of product: ≈200, 50×4
The real product: 53×4=212
The product of 53 and 4, is 212.
The question is asking to estimate the product of 53 and 4, then to record the actual product of these numbers. To estimate, we could round 53 to the nearest ten, which would give us 50, and then multiply by 4:
50 x 4 = 200.
The actual product is calculated by multiplying 53 by 4:
53 x 4 = 212.
So the estimate of the product is 200 and the actual product is 212.

Blue Sky International Airport handles passenger to cargo traffic in a ratio of 8 to 5. If 45 cargo planes landed yesterday, how many passenger flights came in?
Answer:
72 passenger planes
Step-by-step explanation:
ratio passenger to cargo = 8 to 5 = 8/5
Let p = number of passenger planes.
The ratio of passenger to cargo planes that actually landed is p/45.
The ratio in general is 8/5, so 8/5 must equal p/45.
p/45 = 8/5
5p = 45 * 8
p = 9 * 8
p = 72
Answer: I'm guessing 72
Step-by-step explanation:
its says 8 to 5. If you read it correctly you will know that 8 is the number of passengers and 5 is the number of cargo. 45 ÷ 5 = 9 x 8 = 72How to write 2.6 in word form
two - point six
is the answer
The answer you are looking for is "Two and six tenths".
The reason this is, is because 2 is left of the decimal, which makes it "two". Since 6 is to right of the decimal, you have to look at how far it is from the decimal. It being directly after the decimal, it is in the tenths place, making it six tenths. Thus meaning the answer is two and six tenths.

What would my final balance be if I put $425 in the bank for 48 months with an interest rate of 4.75%?
B.)$80.75
C.)$505.75
D.)$344.25
Needed for test corrections by tomorrow. ASAP!
I see choice (A) is missing, so I am giving you two solutions for you to understand and decide which one applies:
(1) Final balance with compound interest - meaning every year you add the year's interest to the principal and earn interest on the increased amount, etc. This is the actual case in real banks:
principal amount is $425 at (annual) interest rate 4.5%
interest amount for 1 year $19.13
Now, use the formula for compound interest
total balance = principal*(1+interest rate)^year
[tex]\$425\cdot(1.0475)^4= \$511.68[/tex]
So the amount after 4 years with compound interest should be $511.68
(2) the silly way: earn interest of $20.1875 every year and keep it separately (not earning additional interest). That'll make 425+4*20.1875=$505.75 which is answer (C)
so if your (A) matches my solution (1) then go with that. If not, choose (C).

Step-by-step explanation:
Solve 3a+4b=1-2c/d for c.
(Can you please show all your steps?)
Hello!
To solve for c, we will need to use SADMEP. SADMEP is strictly used to solve algebraic equations. It is an acronym for subtraction, addition, division, multiplication, exponents, and parentheses. There are some cases in which we need to divide or multiply before subtracting/adding terms, like in this problem. Our main goal is to isolate c.
3a + 4b = (1 - 2c)/d (multiply both sides by d)
d(3a + 4b) = 1 - 2c (subtract 1 from both sides)
d(3a + 4b) - 1 = 2c (divide both sides by 2)
d(3a + 4b)/2 - 1/2 = c
We can simplify still this equation.
(3ad + 4bd)2 - 1/2 = c (distribute d)
3ad/2 + 4bd/2 - 1/2 = c (divide 3ad and 4bd by 2)
3ad/2 + 2bd - 1/2 = c (simplify)
Therefore, c is equal to 3ad/2 + 2bd - 1/2.
Final answer:
c = -d(3a + 4b - 1)/2
Explanation:
To solve for c in the equation 3a+4b=1-2c/d, rearrange the terms to isolate c, multiply both sides by d to eliminate the fraction, and then divide by -2.
To solve 3a+4b=1-2c/d for c, we will isolate the variable c by following these algebraic steps:
First, we need to move all the terms involving c to one side of the equation. The equation should look like this:3a + 4b - 1 = -2c/dNext, multiply both sides by d to get rid of the fraction:d(3a + 4b - 1) = -2cFinally, divide both sides by -2 to solve for c:c = -d(3a + 4b - 1) / 2This is how we derive the expression for c in terms of a, b, and d.
