How do you know if a triangle is sine cosine or tangent?

Jody has 20 tropical fish and Phillip has 2x = 2*20 = 40 tropical fish.
Together, Phillip and Jody have 20 + 40 = 60 tropical fish.

Let x be the number of tropical fish Jody has.
We know that Phillip has twice as many tropical fish as Jody, so Phillip has 2x tropical fish.
We also know that after giving Jody 10 tropical fish, Phillip would have half as many as Jody, so 2x - 10 = x/2.

Solving for x, we get:
x = 20

So Jody has 20 tropical fish and Phillip has 2x = 2*20 = 40 tropical fish.
Together, Phillip and Jody have 20 + 40 = 60 tropical fish.

5(10x) is the  expression for the total area of the wall, the total area you just need to divide by five to find the area of each section and 10x is an expression for the area of each section

The area of Rectangle is length times of width.

Given that Todd and his friends are painting 5 equal sections of a wall.

The wall is 10 feet tall, but its length is unknown.

Let the unknown length is x

Expression for the total area of the wall is 5(10x)

To get area you do like the times width so it’s 10 times X and theres five sections

If you have the total area you just need to divide by five to find the area of each section

10x is an expression for the area of each section of the wall because it’s just the length times the width of the wall segment

Hence, 5(10x) is the  expression for the total area of the wall, the total area you just need to divide by five to find the area of each section and 10x is an expression for the area of each section

If the reaction is first order in A, the rate law is rate = k[A], where k is the rate constant. Since the rate of the reaction is 1.6 x 10⁻³ M/s and the concentration of A is 0.11 M, we can find the value of the rate constant by plugging in the given values:

1.6 x 10⁻³ M/s = k(0.11 M)

Solving for k:

k = (1.6 x 10⁻³ M/s) / (0.11 M) = 14.55 x 10⁻⁴ s⁻¹

So the rate constant for a first order reaction in A is 14.55 x 10⁻⁴ s⁻¹.

If the reaction is second order in A, the rate law is rate = k[A]², where k is the rate constant. Since the rate of the reaction is 1.6 x 10⁻³ M/s and the concentration of A is 0.11 M, we can find the value of the rate constant by plugging in the given values:

1.6 x 10⁻³ M/s = k(0.11 M)²

Solving for k:

k = (1.6 x 10⁻³ M/s) / (0.11 M)² = 0.1395 x 10⁻³ M⁻¹ s⁻¹

So the rate constant for a second order reaction in A is 0.1395 x 10⁻³M⁻¹ s⁻¹.

The amount of markup if markup to 40% is nullified by giving some discount of Rs. 980 is Rs 280.

The markup, expressed as a percentage of cost, is the difference between a product's selling price and its cost.

The markup of 40%

Let's Assume the cost price = Rs 100C

Calculate the markup as shown below,

Mark up = (40 / 100) 100C = Rs 40C

Marked price = 100C + 40C = Rs 140C

Hence, 140C = 980

C = 7

Thus, markup price = 7 × 40 = Rs 280

Therefore, the amount of markup if markup to 40% is nullified by giving some discount of Rs. 980 is Rs 280.

A) In the first case where we don't count the baggage fee, the percent increase is 53.3%

B) In this case the percent increase is 43.6%

We can find the percent increase using the following formula:

100%*(final price - initial price)/initial price

Here we know that:

final price = $345

Initial price = $225

Then the percent increase is:

100%*($345 - $225)/$225 = 100%*0.533 = 53.3%

So the price of the ticket increased by 53.3%

b) If we also count the $50 for the baggage fee with the new ticket price, then the increase is:

100%*($345 + $50 - $225 - $50)/($225 + $50) = 100%*0.436 = 43.6%

Where the $50 fee would be counted on the initial and final price, that is why it appears twice.

The required values are a = 7, b = -2, and c = -4 to make the given expression equivalent to the given expression.

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

Consider expression.

3x/(x+2) + 4x/(x-2)

To begin, we factor out an x from both numerators:

3x/(x+2) + 4x/(x-2) = x(3/(x+2) + 4/(x-2))

Then, factor out a common denominator from the two terms in the parentheses:

x(3/(x+2) + 4/(x-2)) = x((x-2)(3/(x+2)) + (x+2)(4/(x-2)))

Then, we can expand and simplify:

x((x-2)(3/(x+2)) + (x+2)(4/(x-2))) = (7x² - 2x)/(x² - 4)

The simple interest is 7% per year.

Simple interest is the borrowing amount added only to the principal amount.

The formula to calculate the simple interest is;

                                                 S.I. = P x T x R / 100,

Where S.I. is simple interest, P is principal amount, T is time period and R is interest rate in a year.

Given:

Kevin invests money in an account paying simple interest.

He invests $40 and no money is added or removed from the investment. After one year, he has $42.80.

That means,

A = $42.80, P = $40, T = 1 year.

So,

R =(1/T) (A/P - 1)

R = (1/1)((42.8/40) - 1) = 0.07

The value of x, here x is non-negative integer (i.e x> 0) is equals to the eight.

We have, the vertices of a triangle are (0, 0), (x, 2x), and (x, 0), where x > 0 .

Area of triangle formed by those vertices = 64 square units . The area of the triangle whose vertices are (x₁ , y₁) ,( x₂ , y₂) and (x₃ , y₃) is 1/2 ∣x₁(y₂ - y₃) + x₂( y₃ - y₁) + x₃ (y₁ - y₂)|.

Comparing the vertices (0, 0), (x, 2x), and (x, 0) with standard vertices (x₁ , y₁) ,( x₂ , y₂) and (x₃, y₃). We get, x₁ = 0 , y₁ = 0 , x₂

= x , y₂ = 2x , x₃ = x and y₃ = 0.

Now, the area of the triangle is equals to

1/2 ∣0(2x - 0) + x( 0 - 0) + x (0 - 2x)| = 64

=> 1/2| 0 + 0 + (-2x)x| = 64

=> 1/2 | - 2x²| = 64

=> 1/2(2x²) = 64

=> x² = 64

=> x = ±√64

=> either x= - 8 or x = 8 , but x > 0

So, value of x is 8.

The profit is Rs. 200.

The pricing system in which a commodity's (goods or services') price is lower than its listed price is referred to as a "discount." Simply put, "discount" refers to a percentage of the advertised price. A discount is a type of price reduction on products that is seen in consumer transactions. In these transactions, buyers propose a percentage of rebates on various products to increase sales. A discount is the seller's offer of a discount to the buyer.

Given marked price = Rs. 800

discount % = 10%

discount = 10% of 800

discount = 800 x 0.1 = 80

selling price = marked price - discount

selling price = 800 - 80 = Rs. 720

The dealer makes a profit of 20% means is selling the article at 120%.

120%=720

The slope of a graphed line that spans grid points (0, 2) and best represents the slope as -5 (1, -3)

A line's slope determines how steep it is. A mathematical equation for the gradient is called "gradient overflow" (the change in y divided by the change in x). The slope is the ratio of the vertical change (rise) between two points to the horizontal change (run) between those same two spots. When a straight line's equation is written as y = mx + b, the slope-intercept form of an equation is employed to express it. The y-intercept is located at a location where the line's slope is m, b is b, and (0, b). For instance, the slope of the equation y = 3x - 7 and the y-intercept (0, 7).

given

If the line rises to the right, the slope has a positive sign. The slope of this line is negative since it descends to the right. (Removes options C and D)

The ratio of the vertical to horizontal distance between two sites determines the slope's magnitude. This line has a slope of rise/run = -5/1 = -5 because it descends five vertical squares for every square to the right.
