Answer:

a. number of periods over which interest is calculated on the loan

Step-by-step explanation:

A formula should always be accompanied by an explanation of what it calculates and the meaning of each of its variables. This formula calculates P, the periodic payment on a loan of n periods at interest rate i (compounded) per period. The principal amount of the loan is PV.

___

The same formula can also be used to calculate an annuity from which payment P is received at the end of each of n periods. The amount invested is PV and the interest rate per period (compounded per period) is i.

'n' typically represents the number of periods over which interest is calculated in a loan. However, symbols' intended meanings can change depending upon the context.

In most financial and mathematical formulas, the symbol 'n' typically represents the number of periods over which interest is calculated on a loan. It's relevant to note that these periods could be months, years, or any other agreed-upon timeframe. Hence, the correct answer to your question is (a).

However, it's important to state that the representation of variables can change with different contexts. In some scenarios, 'n' could be used to denote the number of years it will take to pay the loan back, but that is not as common as using 'n' for the number of periods.

Answer:

Carey's hourly rate to babysit is $10.

Step-by-step explanation:

Given is -

For each hour he babysits, Anderson earns $1 more than half of Carey’s hourly rate.

Let Carey's hourly rate to babysit be represented by 'c'

So, Anderson's hourly rate will be = [tex]\frac{c}{2}+1[/tex]

Also given that Anderson earns $6 per hour.

So, equaling both, we get;

Answer:

(x, y, z) = (-2, -1, 2)

Step-by-step explanation:

Your graphing calculator can usually solve systems of linear equations easily.

The initial yield of potatoes per acre was 14 tons and after the introduction of the new technology, the yield increased to 18 tons. Therefore, 5600 tons were collected before the technological advances and 7200 tons were collected after.

This problem involves understanding linear equations. Let's denote the initial yield of potatoes per acre as 'x' tons and the yield after the introduction of the new technology as 'y' tons.

It's given that technological advances increase the yield by 4 tons, so we have the equation: y = x + 4. The problem also states that from a 320 acre field 640 more tons were collected than before from a 400-acre field. So, we can write it as: 320y = 400x + 640.

Solve these two equations to find the values of x and y. The initial yield of potatoes per acre (x) was 14 tons while the yield after the introduction of the new technology (y) was 18 tons. Therefore, 5600 tons of potatoes were collected before the technological advances and 7200 tons were collected after.

https://brainly.com/question/4177820

#SPJ12

Before the new methods were introduced, 640 tons of potatoes were collected. After the introduction of the new technology, 0 tons were collected.

To solve this problem, let's assume x is the number of tons of potatoes collected before the new methods were introduced, and y is the number of tons collected after the introduction of the new technology.

According to the given information, the new technology increased the crop of potatoes from 1 acre by 4 tons, so the increase in yield per acre is 4 tons.

From a field of 320 acres, 640 tons more were collected than before from a field of 400 acres. This means that the increase in yield from the reduced field of 320 acres is twice the increase in yield from the initial field of 400 acres.

Setting up the equation, we have:

(y - x) = 2(4)(320 - 400)

(y - x) = 2(4)(-80)

(y - x) = -640

We also know that the total increase in yield is 640 tons, so we have:

x + y = 640

To solve these equations, we can use substitution or elimination method. Solving for x in the second equation, we get:

x = 640 - y

Substituting x in the first equation, we have:

(y - (640 - y)) = -640

2y - 640 = -640

2y = 0

y = 0

Substituting y in the equation x + y = 640, we get:

x + 0 = 640

x = 640

Therefore, before the new methods were introduced, 640 tons of potatoes were collected, and after the introduction of the new technology, 0 tons were collected.

Answer:

less than

Step-by-step explanation:

The multiplying fraction (5/7) is less than 1 so its product with 6 will be less than 6.

___

5/7·6 = 30/7 = 4 2/7 < 6

The expression 5/7×6 results in a value that is less than 6. This is because the value of 5/7 is less than 1, and multiplying it by 6 gives a result that is consequently less than 6.

To determine whether 5/7×6 is less than, greater than, or equal to 6, we perform the multiplication. Multiplying 5/7 by 6 can be viewed as 5 multiplied by 6, which equals 30, and then that result divided by 7. So the calculation is 30÷7, which equals approximately 4.29. Since 4.29 is less than 6, we can conclude that 5/7×6 is less than 6.

When solving mathematical problems involving multiplication and fractions, it's important to eliminate terms wherever possible to simplify the algebra and to check the answer to see if it is reasonable. Comparing the original fraction to 1 before the multiplication can help us understand whether the result will be greater or less than the number we're multiplying. In this case, since 5/7 is less than 1, multiplying it by 6 will give a result that is less than the original number, which is 6.

Answer:

Robert is 7 years old and Maria is 14 years old.

Step-by-step explanation:

You can use 2 variables: m and r and write 2 equations:

m = r +7

m + 2 = 4( r -3)

So 3 * r = 21 or r= 7

Maria and Robert are currently with present ages as 14 and 7 years old, respectively.

Equations are statements in mathematics that have two algebraic expressions on either side of the equals (=) sign.

It demonstrates that the expressions on the left and right sides are connected in the same way.

An equation has components like as coefficients, variables, operators, constants, terms, expressions, and the equal to sign. The "=" sign and terms on both sides are required when generating an equation.

The information is ,

Let's say the equation looks like this: A

Right now, A is valued at

Let Maria's age be x.

Let Robert's age be y.

Maria now has a 7-year age gap with Robert.

Hence, the equation x = 7 plus y (1)

Also, in two years she will be four times Robert's age from the previous three years.

The equation is (x + 2) = 4 (y - 3). (2)

We obtain (7 + y + 2) = 4y - 12 y + 9 = 4y - 12 after simplifying.

We obtain 3y = 21 by subtracting y and adding 12 on both sides.

We obtain y = 7 years old by dividing both sides by 3.

Robert is therefore 7 years old.

And , x = 14 years old

And , the age of Maria is 14 years old

As a result, Maria and Robert are currently 14 and 7 years old, respectively.

Part 1) The measure of angle C is [tex]62\°[/tex]

Part 2) The measure of angle AOB is [tex]56\°[/tex]

Step-by-step explanation:

step 1

Find the measure of angle C

we know that

The inscribed angle measures half that of the arc comprising

so

[tex]m<C=\frac{1}{2}(arc\ AD)[/tex]

we have

[tex]arc\ AD=124\°[/tex]

substitute

[tex]m<C=\frac{1}{2}(124\°)=62\°[/tex]

step 2

Find the measure of angle AOB

we know that

In the isosceles triangle  ODC

∠D=∠C=62°

Remember that

The sum of the internal angles of a triangle must be equal to 180 degrees

so

∠D+∠C+∠DOC=180°

substitute the values

62°+62°+∠DOC=180°

∠DOC=180°-124°=56°

we have that

∠AOB=∠DOC -----> by vertical angles

so

∠AOB=56°

Answer:

Step-by-step explanation:

The range is the difference between the highest and the lowest values in a set of data.  The interquartile range, the IQR, is what's "inside" the box in a box plot, which consists of the difference between the central measures, which are the first and the third quartiles.

Range is the difference between the maximum and minimum values in a dataset, while the Interquartile Range (IQR) is the difference between the first quartile (Q1) and the third quartile (Q3), representing the spread of the middle 50% of the data.

It is calculated by subtracting the minimum value from the maximum value.

For example, if the highest score in a test is 95 and the lowest score is 55,

the range is 95 - 55 = 40.

To find the IQR, we first need to determine the first quartile (Q1) and the third quartile (Q3).

Q1 is the median of the lower half of the data, while Q3 is the median of the upper half.

The IQR is then calculated by subtracting Q1 from Q3.

For example, in a dataset:

If Q1 = 70 and Q3 = 90, then

IQR = 90 - 70 = 20.

The IQR is useful in identifying potential outliers and understanding the spread of the central data.

To calculate how many cups of flour Genise will need for 2 1/2 batches, multiply the amount of flour for one batch (1 1/2 cups) by the number of batches (2 1/2). This results in 3 3/4 cups of flour needed.

To find how many cups of flour Genise will need, we start by writing an equation that reflects the amount of flour needed for one batch times the number of batches she plans to make. Since she needs 1 1/2 cups of flour for one batch and she wants to make 2 1/2 batches, we set up the multiplication:

flour_needed = (cups of flour per batch) * (number of batches)

So the equation will be:

flour_needed = 1 1/2 * 2 1/2

Converting mixed numbers to improper fractions for easier multiplication, we have:

flour_needed = 3/2 * 5/2 = 15/4 cups

Then, we convert the improper fraction back to a mixed number, which is:

flour_needed = 3 3/4 cups of flour

The Law of Sines is helpful when you know one side and its opposite angle.

  a/sin(A) = b/sin(B) = c/sin(C)

Rearranging gives you ...

  B = arcsin(b/a·sin(A)) = arcsin(105/109·sin(70°)) ≈ 64.85138°

  C = 180° -B -A = 45.14862°

  c = a·sin(C)/sin(A) ≈ 82.23360

C=πd : cherry pie delicious

a=πr² : apple pie are too

and to find the area of the saded area, we need to find the area of the big circle and subtract that by the smaller circle area.

so, area of the big circle:

fill in the variables for a=πr²

you get: a=π6²

follow the pemdas, the order of operations. now on the state test don't write pemdas as your answer because people are stupid and they dont take that answer

you do the exponent first then multiply by pie.

you get: 6²=36

36xπ=113.09733552923255658465516179806

round that answer to the nearest tenths and get: 113.1

now time to find the area of the smaller circle!!!

fill in a=πr² and get: a=π3²

its not 6 this time because that was the radius for the bigger circle. the smaller circles radius is half the size as the bigger circle so divide that by two and get 3.

now solve:

a=π3²

a=π9

a=28.274333882308139146163790449516

round and get: 28.27

now subtract the the bigger circles area and the smaller circles area:

113.1 is the bigger circles area

28.27 is the smaller circles area.

113.1 - 28.27 = 84.83

The equation of the perpendicular bisector is  2x + 3y - 3 = 0

Step-by-step explanation:

* How to find the equation of a line from two points (x1 , y1)

 and (x2 , y2) lie on it

- Find the slope of the line using the rule

 The slope (m) = (y2 - y1)/(x2 - x1)

- Use the rule of the equation y - y1 = m (x - x1), where m is

 the slope of the line and (x1 , y1) is a point on the line

* Remember if two line are perpendicular, then the product of

 their slopes = -1, that means one of them is an additive inverse

 and multiplicative inverse to the other

 # Ex: if the slope of a line is a/b, then the slope of the

   perpendicular to it is -b/a

* Now lets read the problem, we need the equation of the

 perpendicular bisector to the line that passes through the

 points (2 , 4) and (-2 , -2)

- Find the slope of the line in the graph by using the given points

 # m = (-2 - 4)/(-2 - 2) = -6/-4 = 3/2

∴ The slope of the perpendicular line = -2/3 ⇒ multiplicative

   inverse and additive inverse of it

* Bisector means intersect it in the mid-point of the given line

- The rule of the mid-point is [(x1 + x2)/2 , (y1 + y2)/2]

∴ The mid-point of the line is [(2 + -2)/2 , (4 + -2)/2] = (0 , 1)

* Now we have the slope and a point on the line, to find the

 equation of the perpendicular bisector its slope is -2/3 and

 a point (0 , 1)

∴ The equation: y - 1 = -2/3 (x - 0)

  The equation : y - 1 = -2/3 x ⇒ Multiply both sides by 3

  The equation : 3y - 3 = -2x ⇒ collect x , y in the same side

  The equation : 2x + 3y - 3 = 0

* The equation of the perpendicular bisector is  2x + 3y - 3 = 0
