In year, 2004, I put $20.00 into an account to save. This account annual interest fee is 0.002%. However, every 10th year the interest rate get doubled and is now 0.004%. After, the 10th year it goes back to the original interest rate of 0.002% annually. If I check the amount I know have in total included my principal of $20.00, in the year of 2021. What would the total amount be of putting it there
9514 1404 393
Answer:
$20.01
Step-by-step explanation:
In 2004–2012, the interest rate is 0.002%. In 2013, it is 0.004%. In 2014–2021, the interest rate is 0.002%. That is, in the 18 years between 2004 and 2021 (inclusive), the interest rate is 0.002% for 17 of them. The effective account multiplier is ...
(1.00002^17)(1.00004^1) = 1.00038006801
Then the account balance is ...
$20 × 1.00038006801 ≈ $20.01
_____
Additional comment
The annual interest earned on $20.00 is $0.0004. If the account balance is rounded to the nearest cent annually, at the end of the 18 years, the balance will still be $20.00. Not enough interest is earned in one year to increase the balance above $20. At the end of the 18 years, the amount of interest earned is 0.76¢ (a fraction of a penny) only if there is no rounding in intervening years.
To rent a certain meeting room, a college charges a reservation fee of $34 and an additional fee of $9.90 and hour. The math club wants to spend less than $123.10 on renting the meeting room. What are the possible amounts of time that they could rent the meeting room? use t for the number of hours the meeting room is rented
Answer:
9 hours
Step-by-step explanation:
Firstly,
Minus $123.10 with $34
123.10-34
= 89.10
(bcuz $34 is the reservation fee)
Secondly,
Divide $89.10 with $9.90 to determine the hours
t = 89.10/9.90
= 9
Last answer = 9 hours

A motorboat takes 4 hours to travel 192 kilometers going upstream.
The return trip takes 3 hours going downstream.
- What is the rate of the boat in still water?
- What is the rate of the current?
Answer:
Step-by-step explanation:
let b be boat velocity
let c be current velocity
(b - c)4 = 192
(b + c)3 = 192
(b - c)4 = (b + c)3
4b - 4c = 3b + 3c
b = 7c
(7c - c)4 = 192
(6c)4 = 192
24c = 192
c = 8 km/hr
b = 7(8) = 56 km/hr

A right triangle is shown below.

What is the tan of x?
Answer:
Tan x = 1
Step-by-step explanation:
As a tangent of 90° is impossible, x must be the measure of both of the 45° angles.
If we assume 3 is the length of one of the shorter legs, it is also the length of the other of the shorter leg
Tangent x = Opposite/Adjacent = 3/3 = 1

Hi there!

I believe your answer is:
A. - 31 - 71 = - 102
B. - 9 + 14 = 5
»»————- ★ ————-««
Here’s why:
⸻⸻⸻⸻
A. The minuend, subtrahend, and difference are parts of a subtraction problem. In the subtraction problem, - 31 - 71 = - 102, the number - 31 is the minuend, the number 71 is the subtrahend and the number - 102 is the difference.
B. When you are adding a negative number to a positive number you are effectively subtracting the second number from the first. ... And then you add the negative number, which means you are moving to the left – in the negative direction.

Solve x/2- 8 = y for x. A. x= 1/2y
Answer:
x = 2y + 16Step-by-step explanation:
Given equation:
x/2 - 8 = ySolve for x:
x/2 = y + 8 ⇒ add 8 to both sidesx = 2y + 16 ⇒ multiple both sides by 2____________

A service station on the interstate charges $2.29 per gallon for gasoline and $1.89 per quart for oil. What would be a reasonable amount to pay for 10 gallons of gasoline and 2
quarts of oil?
O $20
O $23
O $25
O $27
The reasonable amount to pay for 10 gallons of gasoline and 2 quarts of oil will be $27.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
A service station on the interstate charges $2.29 per gallon for gasoline and $1.89 per quart for oil.
Now,
Since, A service station on the interstate charges $2.29 per gallon for gasoline and $1.89 per quart for oil.
Hence, We get;
The cost of 10 gallons of gasoline = 10 × $2.29
= $22.9
And, The cost of 2 quarts of oil = 2 × $1.89
= $3.78
So, The total cost = $3.78 + $22.9
= $26.68
≈ $27
Thus, The reasonable amount to pay for 10 gallons of gasoline and 2 quarts of oil will be $27.

Answer:
-1;undefined;1;0
Step-by-step explanation:
The first one (-9/9), can also be written as - 9/9 = - 1.
The second one (9/0), is undefined because every single term even 0 itself, if you divide it by 0, it'll be undefined!
The third one, we see we have division, and whenever we have division or multiplication and also 2 negative signs, they cancel each other, as you're left with 9/9=1.
The fourth one, whenever you have 0 at the numerator, no matter the denominator(only matters when it's =0, but that's undefined), the result will always be 0 !
You rotate triangle DEF with coordinates D(-2, 2), E (1,5), and F(4, -1) 90° counterclockwise about the origin.
Answer:
70
Step-by-step explanation:
Rotating triangle DEF counterclockwise by 90° about the origin using the rule (x,y) becomes (-y,x) results in new vertices D'(-2, -2), E'(-5, 1), and F'(1, 4).
When rotating triangle DEF counter-clockwise by 90° about the origin using the rule D(x,y) becomes D'(-y,x), the new coordinates are as follows:
⇒ Vertex D(-2, 2) becomes D'(-2, -2),
⇒ Vertex E(1, 5) becomes E'(-5, 1),
⇒ Vertex F(4, -1) becomes F'(1, 4),
This rule swaps the "x" and "y" coordinates while negating one of them, effectively rotating the points 90° counterclockwise around the origin.
Therefore, the new vertices are D'(-2, -2), E'(-5, 1), and F'(1, 4).

The angles of a triangle are A, B and C.
Angle A is three times as big as angle B.
Angle B is half the size of angle C.
What is the size of angle A?
Answer:
∠A = 90°
Step-by-step explanation:
∠A = 3∠B
∠B = 1/2 × (∠C), this can also be written as ∠C = 2∠B
∠A + ∠B + ∠C = 180, because there are 180° inside a triangle
Write angle A, B and C in terms of angle B:
3 ∠B + ∠B + 2 ∠B = 180
Simplify:
6 ∠B = 180
∠B = 180 ÷ 6 = 30°
Work out angle A:
∠A = 3∠B = 3 × 30°
∠A = 90°
