Answer:

41 m²

Step-by-step explanation:

area = base × height

$=(3\sqrt{5}+2)(3\sqrt{5}-2)=3^2\times 5 - 2^2$

Rectangles J and K are similar. If the area of rectangle J is 440, what is the area of rectangle K? I need this today

Hunter-Best [27]

Answer:

$Area = 27.5$

Step-by-step explanation:

Given

$J_{Area} = 440$

$J_{Width} = 22$

$K_{Width} = 5.5$

<em>See attachment</em>

Required

Determine the area of K

First, we need to calculate the length of the rectangle J

$J_{Length} * J_{Width} = J_{Area}$

This gives:

$J_{Length} * 22 = 440$

Divide both sides by 22

$\frac{J_{Length} * 22}{22} = \frac{440}{22}$

$J_{Length} = 20$

So, the length of the rectangle J is 20.

Since both shapes are similar, then:

$J_{Length} : J_{Width} = K_{Length} : `K_{Width}$

Substitute the known values:

$20 : 22 = K_{Length} : `5.5$

Express as fraction:

$\frac{20 }{ 22 }= \frac{K_{Length} }{ `5.5}$

Make Length, the subject of formula

$K_{Length} = \frac{5.5 * 20}{22}$

$K_{Length} = \frac{110}{22}$

$K_{Length} = 5$

The area of K is:

$Area = K_{Length} * K_{Width$

$Area = 5.5 * 5$

$Area = 27.5$

lbvjy [14]

Answer:

On a coordinate plane, a curve starts in quadrant 3 and then increases into quadrant 1. It crosses the y-axis at (0, negative 2) and crosses the x-axis at (1.5, 0)

Step-by-step explanation:

The attached graph is an example of the square root function scaled and translated.

_____

No transformation of the square root curve will turn it into a parabola or into two curves.

The recipe for Perfect Purple Water says, "Mix 8 ml of blue water with 3 ml of red water." Jada mixes 24 ml of blue water with 9

cluponka [151]

Answer:Jada will get same shade as Perfect Purple Water

Step-by-step explanation:

STEP 1

To get the right recipe for Perfect purple water, every new mixture must have an equivalent ratio as the ideal mixture

The ideal mixture is given as

8ml blue water and 3 ml red water.

Step 2

Andre mixes 16ml blue water with 9ml red water

$\frac{8ml}{3ml}$ is not equivalent to $\frac{16ml}{9ml}$

Because dividing Andre's mixture by a common value will not give the equivalent ratio of the ideal recipe

$\frac{16ml}{9ml}$ $\frac{/}{/}$ $\frac{3}{3}$ = $\frac{5.3ml}{3ml}$

Jada mixes 24ml blue water with 9ml red water

$\frac{8ml}{3ml}$ is equivalent to $\frac{24ml}{9ml}$

Because dividing Jada's mixture by a common value gives the equivalent ratio of the ideal recipe

$\frac{24ml}{9ml}$ $\frac{/}{/}$ $\frac{3}{3}$ = $\frac{8ml}{3ml}$

This shows that Jada got the right recipe and will get same shade as Perfect Purple Water but in a higher quantity, 3 times the right recipe for Perfect Purple Water
