The interest owned by Francesco at the end of one year would be $19023.69.
What is the formula to calculate the simple interest on a given principle amount?
The simple interest on a given principle amount [P] at rate [r%] for [t] years is given by -
I = (P x r x t)/100
Given is Francesco who obtains a loan of $18,965.00 at an interest rate of 3% for 1 year.
From the data given, we can write -
Principle amount = [P] = $18,965.00
Rate = [R] = 3%
Time = [T] = 1 year
Now, using the formula for calculating the simple interest, we get -
I = PRT/100
Substituting the values -
I = (18965 x 0.3 x 1)/100
I = (18965 x 0.3)/100
I = 189.65 x 0.3
I = 58.69
Amount = P + 58.69 = 18965 + 58.69 = 19023.69
Therefore, the interest owned by Francesco at the end of one year would be $19023.69

The boca grande causeway in florida is about 1 4/9 times as long as the golden gate bridge in san francisco golden gate bridge is about 9000 feet long about how long is the boca grande causeway
The length of the Boca Grande Causeway = 13,000 feet.
When do we use multiplication ?Repeated addition of the same number is made easier by multiplying the numbers. When we need to merge groups of similar sizes, we employ it. For instance, if there are 5 baskets, each containing 4 apples, we can use multiplication to get the total number of apples, which is 5 x 4 = 20 apples.
We can rapidly determine the total number of things by multiplying. When multiplying, we'll consider the number of groups with similar sizes and the number of items in each group.
Given: The boca grande causeway in florida = 1 4/9 times golden gate bridge
Length of the Golden Gate Bridge = 9000 feet
Thus the length of the Boca grande causeway = 1 4/9 × 9000
= 13/9 × 9000
On further solving we get
= 13 × 1000
= 13,000 feet .

12 minutes .
The tank takes 12 minute for the water level to measure 9 inches deep.
Explain two step problem?A two-step problem is a word problem that must be solved in two steps.While many of these problems have only one step, a two-step word problem necessitates the solution of two different equations. Two different operations (such as multiplication and addition) or two of the same operation may be used in the two-step word problem (like subtraction and subtraction).Given tank measurement = 15 inches .
it decreases 0.5 inches every minute.
We have to the minute at which water level reaches 9 inches deep,
Here the difference of inches is 6 inches .

11,000 with a 5/10/25 chain discount. Calculate the net price and trade discount
After the discount the net price is $7053.75 and the trade discount is 35.875% .
The term discount designates a sum or a percentage subtracted from an item's usual selling price.
A discount is a decrease in the cost of a commodity or service. Chain discounts can also be applied using the complement approach. To calculate each discount's complement, first subtract the discount from 100%. The net-price rate can be calculated by multiplying the complements to find the percentage that you really pay. The dollar value of the discount can also be determined using the complement technique.The given marked price of the article is 11000
Price after first discount of 5% = 11000 - 5% of 11000 = 10450
Price after second discount of 10% = 10450 - 10% of 10450 = 9405
Price after third discount of 25% = 9405 - 25% of 9405 = 7053.75
Therefore the net price is 7053.75.
Therefore the trade discount is = ( 11000 - 7053.75 ) ÷ 11000 = 0.35875
Trade discount percentage = 35.875%
Hence after the discount the net price is $7053.75 and the trade discount is 35.875% .

What is termed as the coefficient of skewness?The coefficient of skewness is a measurement used to evaluate the strength and direction of skewness in a sample distribution using descriptive statistics such as mean, median, or mode. The skewness coefficient is used to compare a distribution of the sample to a normal distribution.Pearson skewness:
The skewness of the a data set is calculated by subtracting the mean from the median and dividing by the standard deviation.
In this case:
The mean is 95, the median is 77, as well as the standard deviation is 16.9. So,
Pearson skewness = (95 - 77)/16.9

A square has a perimeter of 40 m what is the length of each side
Answer:
10m
Step-by-step explanation:
Perimeter means adding up all of the sides of a shape.
One property of a square is that all lengths of a square are the same.
We also know squares have 4 sides.
Lets set up an expression to solve the length for each side with variable S representing the length of a side:
4 * S = 40
Divide each side by 4:
S = 10
Therefore, each side of the square has a length 10m

What is an equation of the line that passes through the point (1,−7)
(1,−7) and is parallel to the line 3x+y=3
3x+y=3?
Answer:
[tex]3x + y = 3 \\ 3 = x - y \\ 3 = x[/tex]
Answer:
y = -3x - 4
Step-by-step explanation:
Pre-SolvingWe are given the equation 3x + y = 3, and we want to find an equation of the line that is parallel to 3x + y = 3.
This same line also passes through the point (1, -7).
Parallel lines have the same slopes. This means that we'll first need to find the slope of 3x + y = 3.
The equation is written in standard form, which is ax+by=c, where a, b, and c are free integer coefficients, but a and b cannot be 0. a is usually non-negative as well.
There is a shortcut into finding the slope when the equation is in standard form; the slope of the line is -a/b, where a is the coefficient in front of x and b is the coefficient in front of y).
The coefficient in front of x is 3, and 1 in front of y.
SolvingSubstitute 3 as a, and 1 as b in -a/b. Don't forget about the - in front of a!
-3/1 = -3
This means the slope of the line is -3.
It is also the slope of the line parallel to it.
We can write the equation of the line we are trying to solve for in standard form, too. However, we could also write it in slope-intercept form.
Slope-intercept form is given as y=mx+b, where m is the slope and b is the y intercept.
As we are already given the slope, we can immediately plug that into the formula.
Replace m with -3.
y = -3x + b
Now we need to find b.
As the equation passes through the point (1, -7), we can use its values to help solve for b.
Substitute 1 as x and -7 as y.
-7 = -3(1) + b
Multiply.
-7 = -3 + b
Add -3 to both sides
-4 = b
Substitute -4 as b into the equation
y = -3x - 4
