To find the original price before the increase, divide the new price by 1 + the percent of increase.

198 / 1.20 = 165

The original price was $165

The price before the increase was $ 165

Percentage can be said as a part of a whole expressed in hundredths .

Let the price of the watch be $ x

According to the problem,

So, we can write x + 20x/100 = 198

⇒ 6x/5  = 198

⇒ x = 165

∴ The price before the increase was $ 165

Step-by-step explanation:

2 * (x + 1) = 8   | :2

x + 1 = 4   | -1

x = 3

Answer:

x = 3

Step-by-step explanation:

2 ( x + 1 ) = 8

⇒ Expand brackets

2 x + 2 = 8

⇒ Minus 2 from both sides

2 x = 6

⇒ Divide by 2 from both sides to isolate x

x = 3

To subtract the given expressions, first, simplify each expression separately by combining like terms. Then subtract the second expression from the first expression by distributing a negative sign and adding it to the first expression.

To subtract the given expressions, (2x^3+7x^2-4) - (2x^2+4x-10), we need to simplify each expression separately and then subtract them. First, combine like terms within each expression. Then, subtract the terms of the second expression from the first expression. This can be done by distributing a negative sign to each term in the second expression and then adding it to the first expression.

So, (2x^3+7x^2-4) - (2x^2+4x-10) = 2x^3+7x^2-4 - 2x^2-4x+10.

Combining like terms, we get 2x^3+(7x^2-2x^2)+(-4-4x)+(10). Simplifying further, we have 2x^3 + 5x^2 - 4x + 6. Therefore, the result of the subtraction is 2x^3 + 5x^2 - 4x + 6.

Answer:

Rectangle

Step-by-step explanation:

Given : A prism and a plane

To Find : The intersection of the prism and the plane is a _______ cross section.

Solution:

We are given a rectangular prism

Let length be l , breadth be b and height be h

When the prism is intersected by plane , The height becomes 0 .

Length and breadth will remain same

So, the obtained figure is rectangle

So, Option B is true .

Hence The intersection of the prism and the plane is a rectangle cross section.

Answer:

The correct option is C.

Step-by-step explanation:

If a line passing through two point then the equation of line is

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

From the given graph it is clear that the line of best fit passing through the points (0,0) and (14,45). So, the equation of line of best fit is

[tex]y-0=\frac{45-0}{14-0}(x-0)[/tex]

[tex]y=\frac{45}{14}x[/tex]

The equation of line of best fit is [tex]y=\frac{45}{14}x[/tex], therefore the correct option is C.

Step-by-step explanation:

Buying price of the part= $ 8.75

Selling price of the part= $ 9.98

sale tax= $0.40

Selling price before sale tax= $9.98-$ 0.40 = $ 9.58

To find the measure of ∠ONK in rectangle MPKN with given conditions, it's determined through the congruency of triangles and properties of a rectangle that ∠ONK is 72°.

The question involves finding the measure of ∠ONK in rectangle MPKN, where the diagonals intersect at point O, and a line segment OA is an altitude of triangle MOP with m∠AOP = 18°. Given the properties of a rectangle, we know that its diagonals bisect each other and are equal in length. Therefore, triangles MOP and NOP are congruent.

Because OA is the altitude to hypotenuse MP of triangle MOP, it creates two right triangles, OAM and OAP. The angle ∠AOP is given as 18°, which means ∠MOA = 90° - 18° = 72° since triangle OAM is a right-angled triangle. Because the diagonals of the rectangle bisect each other at O, triangle ONP is congruent to triangle OMP, and hence ∠ONK (which is also ∠ONP) is equal to 72° as angle ∠ONP is supplementary to ∠MOA in rectangle MPKN.

Using the rule of logarithms

• log [tex]x^{n}[/tex] ⇔ n log x

Hence

log [tex]x^{4}[/tex] - log x³

= 4 log x - 3 log x

=log x

The value of logx⁴ - logx³ will be logx.

The exponent indicates the power to which a base number is raised to produce a given number called a logarithm.

In another word, a logarithm is a different way to denote any number.

If you want to write 1 in logarithm then it will be log(base).

The first method →

Given,

⇒ logx⁴ - logx³

By log property that loga7 = 7loga

⇒ 4logx - 3 logx

⇒ logx

The second method →

This question can also be solved by another log property that

logm - logn = log(m/n)

Since given,

logx⁴ - logx³ = log(x⁴/x³) = logx

Hence, The value of logx⁴ - logx³ will be logx.

I'm not sure about the second point you posted, but I believe the answer is (-2, 1). Here is my work:

Answer:-2,1

Step-by-step explanation:

If the diameter of a circle is 50 yards the radius must be 25 yards.

This is because the radius is always half the diameter of the circle. Since we know the diameter is 50 yards, half of 50 is 25 so the radius must be 25 yards.

Have a great day!

The radius of the circle is 25 yards.

A circle is a round shaped figure which has all its points in one plane and the distance between all the points on its circumference to the center of the circle is equal .

It is given that

Diameter of a circle is 50 yards.

Radius of a circle =  Diameter of circle / 2

Radius of the circle = 50/2 = 25 yards

Answer: The answer is 15 * 14

Step-by-step explanation:

You start with 15 people to choose from to select a president, so you have 15. After removing one person 15-1,=14 you have fourteen people to choose from, to select a vice president. This gives you 15*14.

The expression that can be used to represent the number of ways that a president and a vice-president can be chosen out of a group of 15 people is 15×14 or ¹⁵P₂.

Permutation helps us to know the number of ways an object can be arranged in a particular manner. A permutation is denoted by 'P'.

[tex]^nP_r = \dfrac{n!}{(n-r)!}[/tex]

where,

n is the number of choices available,

r is the choices to be made.

The number of people that are available for the post of the president is 15, while the number of people that are available for the post of vice-president after the president is selected is 14. Therefore,

Number of ways in which president and vice-president can be selected

= ¹⁵P₂

= 15 × 14

Hence, the expression that can be used to represent the number of ways that a president and a vice-president can be chosen out of a group of 15 people is 15×14 or ¹⁵P₂.

Answer:

44, 46

Step-by-step explanation:

The integers are both even, so if the smaller one is x, then the larger one is x+2.

Therefore:

((x) + (x+2))² = 4048 + (x)² + (x+2)²

(2x + 2)² = 4048 + x² + x² + 4x + 4

4x² + 8x + 4 = 2x² + 4x + 4052

2x² + 4x - 4048 = 0

x² + 2x - 2024 = 0

(x + 46) (x - 44) = 0

x = -4+, 44

Since x must be positive, x = 44.  And x+2 = 46.  So the numbers are 44 and 46.

Let's check:

(44 + 46)² = 8100

4048 + 44² + 46² = 8100

[tex]A = 2\pi r * h.[/tex]

Where r is the radius of the right cylinder and h is the height

In this case we know that the diameter d of the cylinder is

[tex]d=2r\\\\r=\frac{d}{2}\\\\r=\frac{12}{2}\\\\r=6\ cm[/tex]

[tex]h=8\ cm[/tex]

Therefore the lateral area is:

[tex]A = 96\pi[/tex]

[tex]A = 301.59\ cm^2[/tex]

Answer:

The lateral area of a right cylinder = 96π cm²

Step-by-step explanation:

Points to remember

The lateral area of a right cylinder  = 2πrh

Where r - Radius of cone and

h - Height of cone

To find the lateral surface area

Here diameter d = 12 cm

then radius r = d/2 = 12/2 = 6 cm

And h = 8 cm

Lateral surface area =  2πrh

= 2 * π *6 * 8 = 96π cm²

Therefore the lateral area of a right cylinder = 96π cm²
