Write an equation that describes this situation.

The sum of the geometric sequence is 88,573.

The formula for the sum of a geometric sequence is

S = a₁(1 - rⁿ)/(1-r),

where a₁ is the first term of the sequence, r is the common ratio between terms, and n is the number of terms in the sequence. In this case, the first term is a₁ = 1, the common ratio between terms is r = 3, and the number of terms is n = 10. Inserting these values into the formula,

we get S = 1(1 - 3⁹)/(1-3) = 1(1 - 19,683)/(-2) = -9,841.5.

Therefore, the sum of the geometric sequence is 88,573.

The price of the two pencils is Rs.100 (expensive) and Rs.60 (cheaper).

Let the price of the expensive pencil be = x

And the price of the cheaper one be = y.

According to the question:

The difference between the price of 2 = 40

Therefore,

x- y =40

Total amount = 1800.

The number of Expensive pencils that can be bought = 1800/x.

The number of Expensive pencils that can be bought = 1800/y.

According to the question,

1800/y -1800/x = 15 (the number of extra pencils)

= (1800x -1800y)/xy = 15

= 1800x -1800y =15xy

= 1800 (x-y) =15xy

Substituting x-y as 40

1800 x 40 =15xy

xy = 4800.

We know that x-y =40

Therefore, x = y+ 40

xy = 4800

(y+40) y = 4800

[tex]y^{2}[/tex] + 40 y = 4800

Using the quadratic equation formula,

y = 52.111 or y = -92.111

Thus, the cost of the cheaper pencil (y)= Rs. 52.111

The cost of the expensive pencil (x) = 52.111 + 40 = Rs 92.111

Therefore the cost of two pencils is =   Rs. 52.111 and Rs 92.111.

Answer:

y ≈ 76.4°

Step-by-step explanation:

To solve for the angle a trigonometric function is being used on, we have to use the inverse of the trigonometric function.

Inverse of tan(y°) = 4.12:

[tex]tan^-1(4.12) = y[/tex]

Next, I used a scientific calculator to find the angle measure of y.

[tex]76.4 = y[/tex]

Answer:

False

Step-by-step explanation:

Vertical angles are always congruent regardless of if the lines are parallel.

The slope to a line perpendicular to y = 3x + 1 is -1/3.

The ratio of how much y grows as x grows by a certain amount is called the slope of a line. A line's slope, or the amount by which y rises as x rises, indicates how steep a line is. Nowhere on the line has a different slope; it is constant. We frequently seek to quantify the steepness in mathematics. The difference between slope A and slopes B and C is obvious. While slope A is just four units high, they both stand at seven. It would therefore seem that steepness and height are related.

To find horizontal line,its equation is y=b where b is constant.Horizontal line is parallel to x-axis of the coordinate plane.To find vertical ,its equation is x=b where b is constant.Vertical line is parallel to y-axis.

A horizontal line is a line extending from left to right and right to left.The slope of horizontal line is always zero.Horizontal lines are always parallel to x-axis.The y-intercepts of a horizontal line y=b is the point (0,b).

A vertical line is a line extending from up to down and downward to upward.Its never moves left to right.Vertical lines are always parallel to y-axis.The equation of a vertical line is x=a and x=-a where x is the x-coordinate of ant point on the line and a is the point where he line crosses the x-intercepts.

Given data: 8,9,12,15,16,20,24,30,32,34

The formula for the mean (x bar) =  sum of observations /no. of observations

Mean (x bar) = 8+9+12+15+16+20+24+30+32+34/ 10

Mean = 200/10

∴ Mean = 20

Now, we find the mean deviation using mean

Mean deviation using mean = 1/n Σ|x- x bar|

where n= number of observations = 10

x= each observation in the data

x bar= mean of the data= 20

Mean deviation using mean

Answer:

A. It is an increase in assets.

Step-by-step explanation:

The Debit section shows what the business purchased which is $12,000 worth of equipment. Hence, the business gained equipment worth $12,000 which is an increase in assets.

Answer:

A. It is an increase in assets.

Step-by-step explanation:

The entry "Equipment 12,000" is listed as a debit in the T-account because it is an increase in assets.

A T-account is a visual representation used in accounting to track and display the balances of a specific account, with the "debit" side showing increases and the "credit" side showing decreases.

When office equipment is purchased, it represents an increase in the company's assets. An increase in assets (or a decrease in liabilities) is recorded as a debit on a company's balance sheet.

In this case, the business is acquiring equipment, which is considered an asset, and therefore, it is debited to reflect the increase in the asset account.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

The total number of pictures = 315

The number of pictures in each page = 6

Since Anne can only fill complete pages, she will use 52 pages. The remaining pictures will be:

The remaining pictures = total pictures - (pictures per page x pages used)

On simplifying the equation , we get

The remaining pictures A = 315 - (6 * 52)

When resolving an inequality, you can do one of the following: • Add the same amount to each side; • Subtract the same amount from each side; • Multiply or divide each side by the same positive amount. You must flip the inequality sign if you multiply or divide each side by a negative number.

You may use three triangle-specific theorems to quickly distinguish similar triangles.

There are three theorems that may be used to determine whether two triangles are similar: Angle - Angle (AA), Side - Angle - Side (SAS), and Side - Side - Side (SSS).

SSS, which stands for "side, side, side," denotes that there are two triangles with identical angles on all three sides. The triangles are congruent if their third sides are the same as those of another triangle.

That is what the SAS regulation says. The triangles are congruent if the two sides and included angle of one triangle are the same as the two sides and included angle of another triangle. Any angle that is created by two specified sides is an included angle.

According to the AA postulate of Euclidean geometry, two triangles are similar if their two corresponding angles are congruent. The fact that the sum of a triangle's internal angles is always equal to 180° leads to the AA postulate.
