Answer:

\(12\sqrt{2}\sqrt[4]{5}\)

or

\(25.38\)

Step-by-step explanation:

We are given:

\(AB = \sqrt{ 48}\\\\BC = 2\sqrt{30}\\\\AC = 2\sqrt{18}\\\\\)

Simplify each square root to the lowest radical:
\(\sqrt{ 48} = \sqrt{16 \cdot 3} = \sqrt{16}\cdot \sqrt{3} = 4 \sqrt{3}\\\\2\sqrt{30} = 2 \sqrt{3 \cdot 10} = 2 \sqrt{3} \sqrt{10}\\\\2\sqrt{18} = 2 \sqrt{9 \cdot 2 } = 2 \sqrt{9} \cdot \sqrt{2} = 2 \cdot 3\sqrt{2} = 6\sqrt{2}\\\\\)

Multiplying all three:
\(4 \sqrt{3} \times 2 \sqrt{3} \sqrt{10} \times 3\sqrt{2}\)

First multiply all terms not under square root:

4 x 2 x 6 = 48

Then multiply all the radicals which are the same:

\(\sqrt{3} \times \sqrt{3}{\sqrt{10} \times \sqrt{2}\)

\(\sqrt{10} = \sqrt{2}\sqrt{5}\)

This works out to
\(\sqrt{3}{\sqrt{3}\sqrt{2}\sqrt{5}\sqrt{2}\)

Rearranging the radicals
\(\sqrt{3}\sqrt{3}\sqrt{2}{\sqrt{2}\sqrt{5} = (\sqrt{3})^2 \cdot (\sqrt{2})^2 \cdot \sqrt{5}\\\\= 3 \cdot 2 \cdot \sqrt{5}\\\\= 6 \sqrt{5}\\\\\)

Multiplying by 48, the value we got by multiplication of the terms not under square root we get this value as:
\(48 \times 6\sqrt{5}\)

\(= 288\sqrt{5}\)

= 643.98757

This is equal to \(AB \cdot BC \cdot AC = A^2B^2C^2 = (ABC)^2\)

 \(ABC = \sqrt{288\sqrt{5}} \\\\\sqrt{288} = \sqrt{144 \cdot 2} = 12 \sqrt{2}\)

\(\sqrt{\sqrt{5}} = \sqrt[4]{5}\)

ABC = \(12\sqrt{2}\sqrt[4]{5}\)

In decimal this would be

\(\sqrt{643.98757} = 25.37691 \approx 25.38\)

The probability that 72% or more of the women in the sample have been on a diet is, 0.1736.

What is probability?

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is.

As given a sample survey interviews an SRS of 209 college women. suppose that 69% of all college women have been on a diet within the last 12 months.

p = 0.69

1 - p = 0.31

n = 209

μp = p = 0.69

σp = √(p(1-p))/n = √(0.69*0.31)/209 = 0.03199

= 1 - p(p < 0.72)

= 1 - p((p - μp) / σp < (0.72 - 0.69) / 0.03199)

= 1 - p(z < 0.94)

= 1 - 0.8264

= 0.1736

Hence, the probability is 0.1736.

Answer:

(A)a translation 5 units down and 2 units to the right followed by a reflection across the y-axis

Step-by-step explanation:

If a point is reflected across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite.

Triangle LMN has points (2, 1), (1, 1), (1, 3).

Triangle L'M'N' has points (-4,-4), (-3,-4), (-3,-2).

From the given options:

Option A: A translation 5 units down and 2 units to the right followed by a reflection across the y-axis

Given the points: (2, 1), (1, 1), (1, 3) of Triangle LMN

Therefore, the sequence of transformation in Option A produces Triangle L'M'N'.

Answer:Which sequence of transformations produces

TriangleL'M'N' from TriangleLMN?

a reflection across the y-axis followed by a translation 5 units down and 2 units right

a translation 5 units down and 2 units to the left followed by a reflection across the y-axis

no sequence of transformations

the answer is ''A'' a translation 5 units down and 2 units to the right followed by a reflection across the y-axis.

The angle postulate that best defined angles CAB and CAD is; Supplementary Angles

We know that there are different angle postulates such as Corresponding angles, complementary angles, supplementary angles and others.

Now, in this case we want to find the angle theorem that best describes angles CAB and CAD. Now, from the given image, it is clear that both angles form a straight line and we know that the sum of angles on a straight line equals 180 degrees.

Since both angles sum up to 180 degrees and we know that these angles are defined as supplementary angles which are linear pairs.

Answer:

X = 6

Step-by-step explanation:

17 - 5 = 12

12/2 = 6

hope this helps...

Answer:

6

Step-by-step explanation:

Find x

Try to get x by itself

2x + 5 = 17

subtract 5 on both sides

2×+5(-5)=17(-5)

by subtracting 5 from its opposite, it turns to 0

now we are left with

2x=12

Next we need to divide

2x is like 2(x) which is multiplication

the inverse is division

when we divide, whatever u do to one side u do to the other

2x/2=12/2

×=12/2

we finally got x by itself

we can break 12/2 even further by dividing and you'd get

×= 6

The amount of rain the city received in July is r = 2.5 inches

Given data ,

City received 3/4 inch of rain on July 31

Now , it represents 3/10 of the total amount of rain this to received in July

So , the equation is represented as A

Now , the value of A is

( 3/10 )r = 3/4

Multiply by 10 on both sides , we get

3r = 30/4

Divide by 3 on both sides , we get

r = 30/12

r = 2.5 inches

Hence , the city received 2.5 inches of rain

The percent increase is 56%

The percent increase if the airline charges an additional $50 baggage fee with the new ticket price is 76%

The formula for determining percent increase is expressed as;

Percent increase = x₂ - x₁/x₁  × 100/ 1

Where;

Now, substitute the values, we have;

Percent increase = $320 - $210/$210  × 100/ 1

Find the difference

Percent increase = $110/$210  × 100/ 1

Percent increase = 0. 52  × 100/ 1

Multiply through

Percent increase = 52%

If there is an increase of $50

Percent increase = $370-210/210 × 100/ 1

= 160/210 × 100/ 1

= 76%

Hence, the values are 52% and 76% respectively,

The correct statements regarding the sides of the triangle are given as follows:

GE > FG > EF.

The side lengths of the triangle are ranked according to the rate established by the law of sines, which states that the ratio between the sine of the angles and the opposite side lengths for the triangle are equal, that is:

sin(a)/A = sin(b)/B = sin(c)/C.

The angles for this problem are given as follows:

The greater than the angles, the higher the value of the side, hence, to keep the ratios constant, we have that:
