10 records in her collection. Now she has 12 records. The percentage  increase of her collection is by 20%.

Percentage:

In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is usually represented by the percent sign "%", although 'it is abbreviated "pct.", "pct.", and sometimes "pc". Percentage is a dimensionless number (pure number); it is unmeasured Unit.

Example :

If 50% of the total number of pupils in a class are boys, this means that 50 out of 100 pupils are boys. If there are 500 students, 250 of them are men.

According to the Question:

We can use the rule of three to solve this problem.

If 100% is 10 records, the percentage of 12 records:

= 12 × 100%/10

= 120%

Then if subtracted 120% -100%, there will be a difference of 20%, i.e. 12 is 20% more, i.e. his collection has increased by 20%.

Answer:

6.25.

Step-by-step explanation:

25 divided by 4 is 6.25.

The total distance they hiked is 2x + y + z = 2x + 24 - x = x + 24 miles.

Let's denote the distance they hiked on level ground, uphill, and downhill as x, y, and z, respectively. Since they turned around at some point, we know they hiked a total distance of x + y + z + x = 2x + y + z.

We can use the formula: time = distance/speed, to write the time they spent on each part of the hike as follows:

Time spent hiking on level ground = x / 4

Time spent hiking uphill = y / 3

Time spent hiking downhill = z / 6

Since they started at noon and arrived at 8:00 pm, we know they hiked for a total of 8 hours. Therefore, we can write the equation:

\(\frac{x}{4} + \frac{y}{3} + \frac{z}{6} + \frac{x}{4} + \frac{y}{3} + \frac{z}{6} = 8\)

Simplifying this equation, we get:

x + y + z = 24

Step-by-step explanation:

In mathematics, a coefficient is a multiplicative factor in some term of a polynomial, a series, or any expression; it is usually a number, but may be any expression (including variables such as a, b and c ).

Answer:

4

Step-by-step explanation:

For this, you need to find the scale factor of two sides that are already given to you.

So, we will have to use the hypotenuse and one of the legs to make sure there is an accurate scale factor.

Hypotenuse:

15 / 5 = 3

Leg:

6 / 2 = 3

____________

So the scale factor is 3.

Using the leg (with the x) we need to divide 12 by the scale factor (3) to give us what x is equal to.

12 / 3 = 4

So, the answer is 4.

In general, the Divergence Test (nth term test) only allows us to determine whether a series diverges or not. It does not help us to determine the convergence of a series. Therefore, none of the other tests apply to this series.

The Divergence Test (nth term test) states that if the limit of the nth term of a series is not equal to zero, then the series diverges.

The series [infinity] 12 n n=1 is defined as follows:

[infinity] 12 n n=1 = 12¹ + 12² + 12³ + ...

The nth term of this series is given by:

aₙ = 12ⁿ As n → ∞, aₙ → ∞,

which means the limit of the nth term of the series does not exist.

Therefore, the series [infinity] 12 n n=1 diverges by the Divergence Test (nth term test).

Part B: The total area of Riley's backyard is 6x² - 14x + 8 Part C: The total area of Riley's garden is x² + 2x - 15 Part D: The area of Riley's backyard not including the garden is 5x² - 16x + 23

What is area?

The word "area" refers to a free space. A shape's length and width are used to compute its area. Unidimensional length is expressed in terms of feet (ft), yards (yd), inches (in), etc. But a shape's area is a two-dimensional measurement. As a result, it is expressed in square measurements like square inches.

To find the total area of Riley's backyard, we need to multiply the length and width:

Total Area = length × width

Total Area = (3x-8) × (2x-1)

Total Area = 6x² - 6x - 8x + 8

Total Area = 6x² - 14x + 8

PART C:

To find the area of Riley's garden, we need to multiply the length and width:

Garden Area = length × width

Garden Area = (x+5) × (x-3)

Garden Area = x² + 2x - 15

PART D:

To find the area of Riley's backyard not including the garden, we need to subtract the garden area from the total area of the backyard:

Backyard Area (without garden) = Total Area - Garden Area

Backyard Area (without garden) = (6x² - 14x + 8) - (x² + 2x - 15)

Backyard Area (without garden) = 6x² - 14x + 8 - x² - 2x + 15

Backyard Area (without garden) = 5x² - 16x + 23

Step-by-step explanation:

The method of calculating the finance charge that Roger's credit card company uses is A. daily balance method.

The daily balance method of calculating credit card's finance charge uses the actual daily balance of the billing cycle instead of being based on an average of the balance throughout the billing cycle.

Using the daily balance method, the finance charges are calculated by summing daily balance multiplied by the daily rate or APR/365.

APR = 19.40%

Monthly APR = 1.62% (19.4%/12)

Daily APR = 0.053%

Date Transaction         Amount ($)

We can use 2x + 7 = 3x - 7 to solve for the corresponding measures.

Let's solve for x:

2x + 7 = 3x - 7

2x + 7 - 2x = 3x - 7 - 2x

7 = x - 7

7 + 7 = x - 7 + 7

14 = x

We can use (2x + 7) + (12y + 1) = 180 to solve for the straight angle.

Substitute for x

(2(14) + 7) + (12y + 1) = 180

(28 + 7) + (12y + 1) = 180

35 + 12y + 1 = 180

Now solve for y:

36 + 12y = 180

36 + 12y - 36 = 180 - 36

The equation of the line passing through (6, 5) and parallel to the given line in general form is:36x + y - 221 = 0

Given the coordinates of a point and the equation of a parallel line, we will find the equation of the line in point-slope and general form.

Point-slope form The equation for a line in point-slope form is given by

y - y₁ = m(x - x₁)

Where(x₁, y₁) are the coordinates of the point and m is the slope of the line.

As the line is parallel to 6y - 78 + 5 = 0, we need to find the slope of the given line.

6y - 78 + 5 = 0

⇒ 6y = 73

⇒ y = 73/6

So, the slope of the given line is m = 6/(-1/6) = -36

Therefore, the equation of the line passing through (6, 5) and parallel to the given line is:

y - 5 = -36(x - 6) ⇒

y - 5 = -36x + 216

⇒ y = -36x + 221

General form ,The equation of a line in general form is given by: Ax + By + C = 0

Where A, B, and C are constants.

Rearranging the equation y - 5 = -36(x) + 216,

Answer:

To construct a triangle with angles 67° and 54° and a side length of 6 cm, follow these steps:

Using a ruler, draw a horizontal line segment of length 6 cm. This will be the base of the triangle.

Using a pair of compasses, set the distance to 3 cm (half the length of the base). Place the point of the compasses on one end of the base line, and draw an arc above the line.

Repeat step 2 on the other end of the base line. The two arcs should intersect at a point above the base line.

Using a protractor, measure the angle between the base line and one of the arcs. It should be 67°.

Using a pencil, draw a line segment connecting the intersection of the arcs to one end of the base line. This line segment will be one of the sides of the triangle.

Measure the length of this line segment using a ruler. This will be the length of the side adjacent to the 67° angle.

The resulting triangle should have angles of 67°, 54°, and 109° (the sum of the angles in any triangle is 180°). The length of the side adjacent to the 67° angle can be measured using a ruler.

You will have approximately $1929.29 available to spend in 6 years.

To calculate the future value of your deposit after 6 years, we can use the formula for compound interest:

Future Value = Present Value * (1 + Interest Rate)^Time

Plugging in the values:

Present Value (PV) = $1491

Interest Rate = 5.07% = 0.0507

Time = 6 years

Future Value = $1491 * (1 + 0.0507)^6

Calculating the expression:

Future Value = $1491 * (1.0507)^6
