Answer:

Right triangles are triangles in which one of the interior angles is 90 degrees, a right angle. Since the three interior angles of a triangle add up to 180 degrees, in a right triangle, since one angle is always 90 degrees, the other two must always add up to 90 degrees (they are complementary).

The side opposite the right angle is called the hypotenuse. The sides adjacent to the right angle are the legs. When using the Pythagorean Theorem, the hypotenuse or its length is often labeled with a lower case c. The legs (or their lengths) are usually labeled a and b.

T=√k(k-b)(k-m).... make b the subject of the formula

Liono4ka [1.6K]

Answer:

b = -T²/k(k-m) + k

Step-by-step explanation:

Given the equation T =√k(k-b)(k-m), we are to make b the subject of the formula

Square both sides

T² = (√k(k-b)(k-m))²

T² = k(k-b)(k-m)

T²/k(k-m) = k-b

Rearrange

k - b = T²/k(k-m)

b - k = - T²/k(k-m)

Add j=k to both sides

b - k + k = - T²/k(k-m) + k

b = -T²/k(k-m) + k

This gives the required expression

The length of a rectangular garden is three times its width, w. The area of the garden is 300 m². Explain why the expression 3w

kogti [31]

If the length is three times the width and the area of the rectangle is

300 $m^{2}$ then the length of rectangle is 30m and width be 10m.

Given that the length is three times the width and the area of the rectangle is 300 $m^{2}$ .

We are required to find the length and breadth of the rectangle.

Area of the rectangle is basically the product of length and breadth.

let the breadth of rectangle be w.

The length of rectangle will be 3w.

Area=Length*Breadth

300=3w*w

300=3 $w^{2}$

100= $w^{2}$

w=+10,-10 but ignore -10 because width cannot be negative.

Length=3w=3*10=30m

Width=w=10m

The area can be written as 3 $w^{2}$ because the area of rectangle is product of length and breadth.

Hence if the length is three times the width and the area of the rectangle is 300 $m^{2}$ then the length of rectangle is 30m and width be 10m.

Together Vondra and Marion have 51 rocks.Marion has 2 times as many rocks as Vondra. How many rocks dose Marion have? How many r

Otrada [13]

Answer:

Marion has 34 rocks and Vondra has 17 rocks

Step-by-step explanation:

1. 51 ÷ 3 = 17

2. Because Marion has 2 times the amount of rocks as Vondra you have do 17 × 2 = 34

3. So, Marion has 34 rocks and Vondra has 17 rocks
