How to determine the compound interestThe formula for calculating compound interest is expressed as;
A = P ( 1 + r/ n) ^nt
Where;
A is the final amountP is the principal amountr is the ratet is the timen is the number of times interest applied per periodNow, let's substitute the values into the formula, we have;
A = $3500 ( 1 + 0. 03 / 0. 25) ^(0.25× 2)
Find the exponent
A = $3500 ( 1 + 0. 03 / 0. 25) ^0.5
A = $3500( 1+ 0. 12)^0. 5
Expand the bracket
A = $3500 (1. 12)^0. 5
A = $3500(1. 05)
multiply the values
A = $3704. 0
Hence, the value is $3704. 0

Which equation represents a line which is parallel to the line y = -2x - 7?
y = -2x is line parallel to given line.
What is line?
A line has length but no width, making it a one-dimensional figure. A line is made up of a collection of points that are endlessly stretched in the opposing directions.
Main body:
The slope-intercept form is
y=mx+b, where
m is the slope and b is the y-intercept.
y=mx+b
Using the slope-intercept form, the slope is −2.
m=−2
To find an equation that is parallel, the slopes must be equal. Find the parallel line using the point-slope formula.
Use the slope −2 and a given point (0,0) to substitute for
x₁ and y₁ in the point-slope form
y−y₁=m(x−x₁)
, which is derived from the slope equation
m=(y₂−y₁)/(x₂−x₁).
y−(0)=−2*(x−(0))
Simplify the equation and keep it in point-slope form.
y+0=−2⋅(x+0)
Solve for y.
y=−2x
Hence y = -2x is line parallel to given line.

This means that increased property taxes will lead to more money being available for teacher salaries which might then increase. There is therefore a positive correlation between the two.
The same is true for the weight of a person and shoe size. This is because the heavier a person is, the larger their shoe size according to research.

Mr. Abbas has bought a Villa in Saar recently for 80,000 BD. He wants to sell it at a 40% profit. House prices are projected to rise on average by 7% a year.
i) How many years will Mr. Abbas have to wait before selling?
The 80,000 BD Villa in Saar Mr. Abbas plans to sell at a 40% profit , with the annual house price growth rate of 7% (compounded) gives the number of years Mr. Abbas has to wait as approximately 5 years
What is the growth rate on an value?The growth rate is the rate at which the value changes within a specified period.
The amount Mr. Abbas bought the Villar in Saar = 80,000 BD
The profit at which he intends to sell it = 40% = 0.4
The rate at which the house prices rise on average = 7 % per annum
The formula for future value, FV is presented as follows;
[tex]FV = PV\cdot \left(1+\dfrac{r}{100} \right)^n[/tex]
Where;
FV = The future value = 80,000 BD + 0.4 × 80,000 BD = 112,000 BD
PV = The present value = 80,000 BD
r = The rate at which the house prices increases annually
n = The number of years
Which gives;
[tex]112,000 = 80,000\cdot \left(1+\dfrac{7}{100} \right)^n[/tex]

John is in charge of feeding the pigs and cows on the farm. The cow's food costs twice as much as the pig's food. There are 46 cows and 22 pigs on the farm. John has an $860 budget for food a month. How much can John spend on food for each cow per month?
The amount John will spend on food for each cow per month is approximately 15.08 dollars
How to find the how much each cow feed per month?John is in charge of feeding the pigs and cows on the farm.
The cow's food costs twice as much as the pig's food.
Let
x = cost of pigs food
y = cost cow's food
Hence,
y = 2x
There are 46 cows and 22 pigs on the farm. John has an $860 budget for food a month.
46y + 22x = 860
Therefore, let's combine the system of equation.
y = 2x
46y + 22x = 860
46(2x) + 22x = 860
92x + 22x = 860
114x = 860
x = 860 / 114
x = 7.5 dollars
y = 2(7.54) = 15.08 dollars
Therefore, the cost of food for each cow is 15.08 dollars

What is the Pythagorean theorem?Pythagorean theorem states that in the right angle triangle the hypotenuse square is equal to the square of the sum of the other two sides.
According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.
Given that It is 163 cm from your eyes to your toes. You're standing 220 cm in front of a tall mirror.
The distance between the image of toes and eyes will be calculated as,
H² = P² + B²
H= √(P² + B²)
H = √(163² + 220²)
H = √(26569+48400)
H = √74969
H = 273.80 cm

Explain on your work paper how you made this conclusion. Invalid
Nice work on selecting "invalid" as the correct answer.
The reason why this argument is invalid is because the 'x' could be in circle B or could be outside circle B. There's simply not enough information.
The venn diagram would either be (A) or (D).
The only information we know is that Fred is does not live in San Francisco, so the 'x' will not be placed inside circle A.
Ignore any diagram where x is on the edge of a circle. That isn't allowed in venn diagrams because a person is either in San Francisco, or they aren't (same goes with California). We can't have blurry boundaries like that. This means venn diagrams (B) and (C) are nonsensical.

A scientist mixes water (containing no salt) with a solution that contains 20% salt. she wants to obtain 120 ounces of the mixture that is 15 % salt. How many ounces of water and how many ounces of the 20% salt solution should she use?
Answer:Say w= the amount of water in oz, then the 60% of the solution is 250 - w
Set up the equation:
Use distributive property first
0.60(250-w) = 0.15 x 250
Isolate to solve for w
150- 0.60w= 37.5
-0.60w= 37.5-150
0.60w= -112.5
w= 187.5 ounces
250-187.5= 62.5 ounces salt solution
Therefore, she must use 187.5 ounces of water and 62.5 ounces of salt solution for her experiment.

A firm manufactured 1000 Tv sets during its first year.the total firms production during the 10 year of operationis 29035 sets .
For each the level of output for 15th year using per year constant increase in production .
Answer:
6922 TV sets
Step-by-step explanation:
You want the production in the 15th year if production in the first year is 1000 and it increases yearly by a constant amount. The total production in the first 10 years is 29035.
Arithmetic seriesAn arithmetic series is one that has a constant difference from one term to the next. If a1 is the first term of the series, and d is the common difference between terms, the n-th term is ...
an = a1 +d(n -1)
And the sum of n terms is ...
Sn = (2a1 +d(n-1))(n/2)
ApplicationTo find the 15th term, we can make use of the given values to find the common difference, then use the formula for the n-th term.
S10 = (2(1000) +d(10 -1))(10/2) . . . . . sum formula with a1=1000
29035 = 10000 +45d . . . . . . . . . . . simplified
d = (29035 -10000)/45 = 423 . . . . the increase in production each year
Production in the 15th year is ...
a15 = 1000 +423(15 -1) = 1000 + 5922 = 6922
The output in the 15th year was 6922 TV sets.
Comet Lee borrowed $16,000 on a 6%, 90-day note. After 20 days, Comet paid $2,000 on the note. On day 50, Comet paid $4,000 on the note. What are the total interest and ending balance due by the U.S. Rule? Use ordinary interest. (Use 360 days. Do not round the denominator in your calculation and round your final answers to the nearest cent.)
The total amount of interest and the final debt owed under the US Rule is $191.09.
Given that,
Comet Lee took out a $16,000 loan with a 90-day, 6% note. Comet settled the note for $2,000 after 20 days. Comet settled the note for $4,000 on day 50.
We have to find what is the total amount of interest and the final debt owed under the US Rule.
First,
To calculate $2000 per 20 days.
We know that,
i=p×r×t
Here,
i is interest.
p is principal amount.
r is rate of interest
t is time.
So, p is $1600
r is 6%
t is 20 days is 20/360
So,
i= 1600×0.06×20/360
i= $53.33
Apply partial payment to interest due,
$2000-$53.33= $1946.67
Next,
Subtract remainder of payment from principal is adjusted balance
Adjusted balance =$16000-$1946.67
Adjusted balance =$14053.33
Now, Second,
To calculate $4000 per 50 days.
We know that,
i=p×r×t
So, p is $14053.33
r is 6%
t is 50 days is 30/360
So,
i= 14053.33×0.06×30/360
i= $70.27
Apply partial payment to interest due,
$4000-$70.27= $3929.73
Next,
Subtract remainder of payment from principal is adjusted balance
Adjusted balance =$14053.33-$3929.73
Adjusted balance =$10123.6
Now, for 40 days
i= 10123.6×0.06×40/360
i= $67.49
So, balance is 10123.6+67.49= $10191.09
When max make two makes partial payments,
The total interest is $53.33+$70.27+$67.49= $191.09
Therefore, the total amount of interest and the final debt owed under the US Rule is $191.09.
