Kit and Kat are building a kite for the big kite festival. Kit has already

Lunna [17]

Kat should tell Kim that It's too late to change the area of this kite because the length of the diagonals of a kite determines its area.

<h3>How to calculate the area of a kite?</h3>

In Mathematics, the area of a kite is equal to one-half the product of the length of its diagonals. Mathematically, the area of a kite can be calculated by using this formula:

A = ½ × d₁ × d₂

<u>Where:</u>

A is the area of a kite.

d₁ and d₂ are the length of the diagonals of a kite.

Since Kit has already cut his sticks for the diagonals, Kat should tell him that it's too late to change the area of this kite because the length of the diagonals of a kite determines its area.

Is 3/x+4/y=2 linear or non-linear

Eduardwww [97]

The given equation is non-linear.

Solution:

Given expression is $\frac{3}{x} +\frac{4}{y} =2$ .

To find the equation is linear or non-linear.

Linear equation is a straight line which is in the form ax + by + c = 0.

Otherwise it is non-linear equation.

⇒ $\frac{3}{x} +\frac{4}{y} =2$

Do cross multiply for the fractions to make the denominators same.

⇒ $\frac{3y}{yx} +\frac{4x}{yx} =2$

⇒ $\frac{3y+4x}{yx} =2$

Do cross multiplication.

⇒ $3y+4x=2yx$

⇒ $4x+3y-2yx=0$

Here, there is no constant term.

So, the equation is not a straight line.

Hence, the given equation is non-linear.

Iteru [2.4K]

Answer:

thirteen sixteenths

Step-by-step explanation:

Three eighths plus seven sixteenths equals blank

3/8 + 7/16 = ?

= (2*3)+(1*7)/16

= (6+7)/16

= 13/16

13/16 is equivalent to thirteen sixteenths
