Please HELP WILL MARK BRAINLIEST 25 POINTS!!!!

The rectangle shown is dilated by a scale factor of 15.
What is the length of side A'B' and side B'D'?

Answer:

Step-by-step explanation:

For the first statement, we need to find the percentages of sold hats. The percentage of white hats sold was (120/200) * 100 = 60% and the percentage of black hats sold was (210/300) * 100 = 70%. The first statement is "The musical group sold 60% of the white hats and 70% of the black hats."

The second statement asks us to compare the 2 percentages, and since 70% > 60%, the statement would be "A greater percentage of black hats were sold." Hope this helps!

Answer:

  4.6

Step-by-step explanation:

There are a number of "improvement" techniques that can be used to improve an estimate of a solution to a polynomial. Some of them use the polynomial itself to form the iterator function.

There are a number of ways we can solve the given equation for x. Often, at least one of these will converge when used for improving the estimated value of x.

  x₁ = (x^3 -72)/6 . . . . . . . add 6x-72, divide by 6

  x₂ = 72/(x^2 -6) . . . . . . . factor out x and divide by its coefficient

  x₃ = ∛(72 +6x) . . . . . . . add 6x and take the cube root

The first two of these iterators tend to diverge. For x = 4.5, they give ...

  x₁ = (4.5³ -72)/6 = 3.1875

  x₂ = 72/(4.5² -6) = 5.0526

Both of these stray out of the given interval of [4, 5].

However, the third one tends to converge, so can give us a useful approximation in one iteration:

  x₃ = ∛(72 +6×4.5) ≈ ∛99 ≈ 4.6261

Applying this again, we get ...

  x ≈ ∛(72 +6·4.6261) ≈ 4.6378

The approximate root to 1 decimal place is 4.6.

Additional comment

One of the quickest converging iterators is that provided by Newton's method. For finding the solution to f(x) = 0, it uses ...

  x₁ = x -f(x)/f'(x) . . . . . . . where f'(x) is the first derivative

For this problem, we can define ...

  f(x) = x^3 -6x -72   ⇒   f'(x) = 3x^2 -6

  x₁ = x -(x^3 -6x -72)/(3x^2 -6) = (3x^3 -6x -x^3 +6x +72)/(3x^2 -6)

  x₁ = (2x^3 +72)/(3x^2 -6)

Then for x = 4.5, the "improved" solution is ...

  x₁ = (2(4.5³) +72)/(3(4.5²) -6)) = 254.25/54.75 = 339/73 ≈ 4.6438

A second iteration gives ...

  x ≈ 4.639026 . . . . accurate to 5 decimal places

With this iterator, the number of accurate decimal places tends to double with each iteration.

The domain of a graph is the possible input values the graph can take.

The domain of the graph is: [tex]\{10, 20, 30, 40, 50, 60, 70, 80, 90, 100\}[/tex]

The score (on the x-axis) represents the input values.

From the graph, we have:

This means that the domain of the graph is from 10 to 100

From the given options, (d) is correct;

Because it represents scores between 10 and 100 (inclusive)

Critical thinking? We're in trouble.  It's hard for me to tell what grade this is.

Stem and leaf is fine but let's just write out the data.

Rich: 35 37 41 42 43 44 45 48 50 55   n=10

Will: 42 43 44 44 46 47 47 48 49 50    n=10

Use measures of center and measures of variation ...

The three measures of center typically used are the mean, the median and the mode.

Rich's sum = 440 so Rich's mean = 440/10 = 44

Rich's middle values are 43 and 44 so Rich's median = 43.5

All Rich's scores are unique so he doesn't really have a mode.

Will's sum = 460, Will's mean = 460/10 = 46

Will's middle numbers are 46 and 47 so median 46.5

Will's data has two modes tied, 44 and 47.  

OK, so far these say Rich is a better golfer; he has lower mean and median scores than Will.  (Low score is better in golf.)

Let's look at measures of variation.  I'm guessing that they don't want to you calculate standard deviation.  So we'll do range and mean absolute deviation.

The range is max-min.

Rich's range is 55-35=20

Will's range is 50-42=8

Will is more consistent.

Rich's mean is 44, his scores are here; let's calculate absolute deviation:

Score    35 37 41 42 43 44 45 48 50 55

AbsDev  9   7    3  2   1   0     1   4   6 11

Rich's deviations add to 44 so his MAD is 4.4

Will's mean is 46

Score: 42 43 44 44 46 47 47 48 49 50

AbsDev 4  3  2    2  0    1   1     2    3   4

The sum is 22, Will's MAD is 2.2

Based on the measures of variation, Will is a more consistent golfer.  He's on average worse than Rich, but he always manages to stay pretty close to his average while Rich is all over the place.

Still I'd go with Rich for the tournament.

Use SOH CAH TOA

TanB=14.1/22.9

Answer:r*s = 168

Step-by-step explanation: (2x-1)(6x) = 12 x^2 - 6x

r(s(x)) = 2 (6x) - 1 = 12 x - 1

r(x) - s(x) = (2x-1) - 6x = -4x -1

r(x) = s(x) when 2x-1 = 6x or x = -1/4

r(4) = s(4) never

(r*s)(4) = 12 x^2 - 6 x = 12*16 - 24 =168

Answer:

the rectangle by 170 square inches, let me know if im right :)

Step-by-step explanation:

 Andrea is incorrect. Given 3 tiles will not fit together perfectly.

As shown in the picture,

If the tiles join perfectly at a point, sum of all angles around the joining point should be 360°.

Expression for the measure of the interior angle of a polygon,

Interior angle of a polygon = [tex]\frac{(n-2)\times 180^\circ}{n}[/tex]

Interior angle of a pentagon = [tex]\frac{(5-2)\times 180^\circ}{5}=108^\circ[/tex]

Interior angle of a hexagon = [tex]\frac{(6-2)\times 180^\circ}{6}=120^\circ[/tex]

Interior angle of an octagon = [tex]\frac{(8-2)\times 180^\circ}{8}=135^\circ[/tex]

To prove that the given tiles fit together perfectly → Sum of all the angles around the common point should be 360°

Sum of all interior angles = 108° + 120° + 135°

                                          = 363°

   Therefore, given tiles will not fit together perfectly.

Answer:

~49.9

Step-by-step explanation:

To get the mean, we must add all the numbers then divide by the amount of numbers there were.

42 + 45 + 58 + 63 + 52 + 42 + 47 = 349

Since we have 7 numbers we can do

349/7 ~ 49.9

Answer: 49.8 (50 if rounded to the nearest ones place)

Step-by-step explanation: First, let's put the number from greatest to least...and we also have to add all the numbers...

42 + 42 + 45 + 47 + 52 + 58 + 63 = 349

Lastly, we have to divide the total by how many numbers there are on the data set...there's 7

349 ÷ 7 = 49.8 (50 if rounded to the nearest ones place)

Therefore, the mean is 49.8 or 50, I hope this helps!

Answer:

Height of cylinder (h) = (4/3)R

Step-by-step explanation:

Given:

Radius of cylinder (r1) = R

Height of cylinder (h) = H

Radius of sphere (r2) = R

Volume of cylinder = volume of sphere

Find:

Height of cylinder (h) = H = ?

Computation:

[tex]Volume\ of\ cylinder = volume\ of\ sphere\\\\ \pi (r1)^2h =\frac{4}{3} \pi (r2)^3\\\\\pi (R)^2h =\frac{4}{3} \pi (R)^3\\\\ h=\frac{4}{3} (R)[/tex]

Answer:

[tex]y =\frac{2}{5}x[/tex]

Step-by-step explanation:

To find the equation, we need to use two points, which can be (0,0) and (5,2).

First, we find the slope

[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} } =\frac{2-0}{5-0}=\frac{2}{5}[/tex]

Therefore, the slope for the equation is 2/5.

Now, we use the point-slope formula to find the equation

[tex]y-y_{1} =m(x-x_{1} )\\y-0=\frac{2}{5}(x-0)\\y =\frac{2}{5}x[/tex]

Therefore, the equation that represents this situation is [tex]y =\frac{2}{5}x[/tex]

Answer:

4(x - 5)(x - 8)

Step-by-step explanation:

Given

4x² - 52x + 160 ← factor out 4 from each term

= 4(x² - 13x + 40) ← factor the quadratic

Consider the factors of the constant term (+ 40) which sum to give the coefficient of the x- term (- 13)

The factors are - 5 and - 8, since

- 5 × - 8 = + 40 and - 5 - 8 = - 13, thus

x² - 13x + 40 = (x - 5)(x - 8)

Then

4x² - 52x + 160 = 4(x - 5)(x - 8)
