Answer:

$186.2

Step-by-step explanation:

   38 kg costs $144.40

∴ 1 kg costs = \frac{144.40}{38}  = $3.8

   49 kg costs = 3.8  x  49

                        = $186.2

We apply the rule of three:

kg of onions          $

38 ------------------- 144.40

49-----------------------x

First it is <u>49 x 144,40</u>, and after it is divided by <u>38</u>, therefore:

\bf{x=\dfrac{49*144.40}{38}= \dfrac{5605.6}{38}=186.2  }

Put so much, 49 kilograms of onion count $ 186.2.

The perimeter of a rectangle is 48 centimeters. the relationship between the length, the width, and the perimeter of the rectang
serious [3.7K]

Answer:

1. 14 cm

2. 20.4 cm

3. 24 - w

Step-by-step explanation:

Let's start with the last question, as it'll make answering the previous two a lot easier. In the 3rd question, we are asked to create a formula to find the length of a given rectangle, using its given perimeter of 48 centimeters and width of w centimeters.

Therefore, let the length of the rectangle be l, we can construct the following equation:

2l + 2w = 48\\\to2l = 48 - 2w\\\to l = \frac{48 - 2w}2\\\to l = 24 - w


Now we have a formula that defines our length, if given the width of the rectangle. The only thing from here on out is to substitute the given widths to the formula we just found.

1. w = 10 , therefore, l = 24 - 10 = 14.

2. w = 3.6 , therefore, l = 24 - 3.6 = 20.4.

All the cubes root of <br><img src="https://tex.z-dn.net/?f=%20%5Csqrt%7B3%20%2B%20i%7D%20" id="TexFormula1" title=" \sqrt{3 + i

If you're looking for the cube roots of √(3 + <em>i </em>), you first have to decide what you mean by the square root √(…), since 3 + <em>i</em> is complex and therefore √(3 + <em>i </em>) is multi-valued. There are 2 choices, but I'll stick with 1 of them.

First write 3 + <em>i</em> in polar form:

3 + <em>i</em> = √(3² + 1²) exp(<em>i</em> arctan(1/3)) = √10 exp(<em>i</em> arctan(1/3))

Then the 2 possible square roots are

• √(3 + <em>i</em> ) = ∜10 exp(<em>i</em> arctan(1/3)/2)

• √(3 + <em>i</em> ) = ∜10 exp(<em>i</em> (arctan(1/3)/2 + <em>π</em>))

and I'll take the one with the smaller argument,

√(3 + <em>i</em> ) = ∜10 exp(<em>i</em> arctan(1/3)/2)

Then the 3 cube roots of √(3 + <em>i</em> ) are

• ∛(√(3 + <em>i</em> )) = ¹²√10 exp(<em>i</em> arctan(1/3)/6)

• ∛(√(3 + <em>i</em> )) = ¹²√10 exp(<em>i</em> (arctan(1/3)/6 + <em>π</em>/3))

• ∛(√(3 + <em>i</em> )) = ¹²√10 exp(<em>i</em> (arctan(1/3)/6 + 2<em>π</em>/3))

On the off-chance you meant to ask about the cube roots of 3 + <em>i</em>, and not √(3 + <em>i </em>), then these would be

• ∛(3 + <em>i</em> ) = ⁶√10 exp(<em>i</em> arctan(1/3)/3)

• ∛(3 + <em>i</em> ) = ⁶√10 exp(<em>i</em> (arctan(1/3)/3 + 2<em>π</em>/3))

• ∛(3 + <em>i</em> ) = ⁶√10 exp(<em>i</em> (arctan(1/3)/6 + 4<em>π</em>/3))
