Answer:

(d) AE = (32√6)/3

Step-by-step explanation:

The side length ratios in a 30-60-90 triangle are 1 : √3 : 2. In a 45-45-90 triangle, they are 1 : 1 : √2.

So, we have the side length ratios ...

CE : CD = 2 : √3

BE : CE = √2 : 1

AE : BE = 2 : √3

Then the ratio AE : CE is ...

$\dfrac{AE}{CD}=\dfrac{2}{\sqrt{3}}\cdot\dfrac{\sqrt{2}}{1}\cdot\dfrac{2}{\sqrt{3}}=\dfrac{4\sqrt{2}}{3}$

Multiplying by the length of CD, we have ...

AE = (8√3)(4√2)/3

AE = (32√6)/3 . . . . . matches the last choice

A particular shade of paint is made by mixing 5 parts red paint and 7 parts blue paint. To make this shade, Shannon mixed 12 qua

SSSSS [86.1K]

<u>Answer:</u>

No, Shannon didn’t mix the correct shade

<u>Explanation: </u>

Ratio required for the shade Red : Blue = 5 : 7

The ratio formed of Shannon must be equal to the above standard ratio

But Shannon’s ratio which was mixed for red and blue is

= Red : Blue

= 8 : 12

= 2 : 3, which is not equal to 5 : 7.

Therefore it is proved that Shannon mixing does not matches with the required mixing ratio which is 5:7.

Answer:

g=12

Step-by-step explanation:

4(2y)=24

8y=24

$y = \frac{24}{8}$

y=3

${4y}^{2} = yg$

Since we know the value of y we substitude

${4 \times 3}^{2} = 3g$

36=3g

g=12

Answer:

( 6, pi/6)

Step-by-step explanation:

( 3 sqrt(3), 3)

To get r we use x^2 + y ^2 = r^2

( 3 sqrt(3) )^2 + 3^2 = r^2

9 *3 +9 = r^2

27+9 = r^2

36 = r^2

Taking the square root of each side

sqrt(36) = sqrt(r^2)

6 =r

Now we need to find theta

tan theta = y/x

tan theta = 3 / 3 sqrt(3)

tan theta = 1/ sqrt(3)

Taking the inverse tan of each side

tan ^-1 ( tan theta) = tan ^ -1 ( 1/ sqrt(3))

theta = pi /6
