Models are smaller than the real thing.

So if a house is 22 meters long, a model (like a Lego version) would be how long? The scale they give says 1cm (model length) = 4 meters (real length).

How many measures of 4 meters are in 22?

22/4 = 5 1/2, so the model would be 5.5 or 5 1/2 cm long.

Answer:

Rotations, Reflections

Step-by-step explanation:

This is going to be our answer because we know that a figure has some kind of rotation.

A rotation is when a shape can be rotated in some way. A reflection is a transformation representing a flip of a figure. Figures may be reflected in a point, a line, or a plane. When reflecting a figure in a line or in a point, the image is congruent to the preimage. A reflection map every point of a figure to an image across a fixed-line.

So our answer would be Rotations, Reflections!

What is the coefficient of the second term of the trinomial? (In other words, what is B?)

(3x − 1)^2 = 9x^2 −Bx + 1

In the blank, write what B equals. Use only numbers - no letters or spaces.

Answers

Answer:

b = 6

Step-by-step explanation:

Let's solve for b.

(3x−1)2=9x2−bx+1

Step 1: Flip the equation.

−bx+9x2+1=9x2−6x+1

Step 2: Add -9x^2 to both sides.

−bx+9x2+1+−9x2=9x2−6x+1+−9x2

−bx+1=−6x+1

Step 3: Add -1 to both sides.

−bx+1+−1=−6x+1+−1

−bx=−6x

Step 4: Divide both sides by -x.

b = 6

This is a question for geometry and its pretty hard.

Answers

Answer:

m EAD = 56

m EDA = 35

x = 4

Step-by-step explanation:

In a parallelogram, the diagonals bisect each other. This means that AE and EC are equal. To find x, simply set 2x + 3 = 11, and solve.

2x + 3 = 11

2x = 8

x = 4

Additionally, since the sides of a parallelogram are parallel, BC + AD are parallel, as are AB + DC. This make ECB + EAD and EBC + EDA opposite interior angles (have same measure). Thus, since we know ECB = 56 and EBC = 35, EAD also = 65 and EAD also = 35

The Correct Answer is 4!

Step-by-step explanation:

We know on triangle 1 that 2 of the sides are 2 and 4 and there a right angle, an angle that has 90 degrees

with this we can calculate the top angle to be 26.565 which combined on both sides is equal to 90, lust you will then have to subtract 90 minus 26.565 and you will get 63.435. Now that we know than the top angle is equal to 63.435, the 2nd angle is equal to 90 degrees which by the way resembles a right angle, and that 1 side of the 3 sides is 2 we can conclude though the triangle formula that...

Step-by-step explanation:

Please look at the attachment down below.

Hope this helped! :)

The  sum of three number is 35.

What is Square?

A square number is the result when a number has been multiplied by itself.

For example, 25 is a square number because it's 5 lots of 5, or 5 x 5.

Given:

if the number given is 9

9² - (9 - 1)² = 9² - 8²

                 = 81-64

                  = 17.

if the number given is 6.

6² - (6 - 1)² = 6² - 5²

                 = 36-25

                 = 11.

if the number given is 4.

4² - (4 - 1)²= 4² - 3²

                = 16-9

                = 7.

Thus, the sum of three number is

=17 + 11 + 7

= 35

Part A: 0.10x + 0.25 = 0.80 (dimes are 10 cents or 0.10 dollars, quarters are 0.25 dollars)
Part B: Plug in what you DO know and solve the one you DON’T:
0.10x + 0.25(2) = 0.80
0.10x + 0.50 = 0.80. Subtract 0.50 from both sides:
0.10x = 0.30 (Divide both sides by 0.10)
x = 3

A piece of paper is 0.1 millimeter thick. When folded, the paper is twice as thick.

Find both the explicit and recursive rule for this geometric sequence.

Answers

Answer:

sorry i am struggling the same

Step-by-step explanation:

2+2=4

The answers to each part are mentioned below.

What is geometric sequence? What is an exponential function? Differentiate between equation and expression?  geometric sequence : A geometric sequence is a special type of sequence where the ratio of every two successive terms is a constant. This ratio is known as a common ratio.function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.

Given is a piece of paper is 0.1 millimeter thick. When folded, the paper is twice as thick.

We can write the geometric sequence as -

0.1, 0.2, 0.4, 0.8 ......

The explicit formula for a geometric sequence is of the form -

        a{n} = arⁿ ⁻ ¹

        where [r] is the common ratio.

The recursive formula for a geometric sequence is of the form -a{n} = a{n - 1}r

For the geometric sequence -

0.1, 0.2, 0.4, 0.8 ......

The explicit formula will be : a{n} = (0.1)(2)ⁿ ⁻ ¹ The recursive formula will be : a{n} = 2a{n - 1}

If the paper is folded 7 times, we can write the thickness as -

y{7} = (0.1)(2)⁶ = (0.1) x (64) = 6.4

To surpass the Mount Everest, we can write -

8850 < (0.1)(2)ⁿ ⁻ ¹

(2)ⁿ ⁻ ¹ > 88500

(2)ⁿ/2 > 88500

(2)ⁿ > 177000

n log(2) > log(177000)

n > {5.25/log(2)}

n > 17.44

n > 18

Therefore, the answers to each part are mentioned above.

An hour before showtime only 105 people have a ride for a concert according to sales 95% of the people have yet to arrive how many tickets were sold for the concert explain

Answers

Given:

An hour before showtime only 105 people have arrived for a concert.

According to sales 95% of the people have yet to arrive.

To find:

The total number of tickets sold.

Solution:

Let x be the total number of tickets sold.

According to sales 95% of the people have yet to arrive.

[tex]100\%-95\%=5\%[/tex]

It means, only 5% people have arrived.

[tex]\dfrac{5}{100}x=105[/tex]

[tex]\dfrac{1}{20}x=105[/tex]

[tex]x=105\times 20[/tex]

[tex]x=2100[/tex]

Therefore, the total 2100 tickets were sold.

Consider sample data with x = 12 and s = 3. (a) Compute the coefficient of variation. % (b) Compute a 75% Chebyshev interval around the sample mean. Lower Limit Upper Limit

Answers

Answer: a) 25%

b) 75% Chebyshev interval around the sample mean=(6,18)

Step-by-step explanation:

Given: Sample mean: [tex]\overline{x}=12[/tex]

Sample standard deviation: s= 3

a) Coefficient of variation = [tex]\dfrac{s}{\overline{x}}\times100[/tex]

[tex]\\\\=\dfrac{3}{12}\times100\%=\dfrac{100\%}{4}\\\\=25\%[/tex]

b) According to the Chebychev's theorem,

75% of the population lies within 2 standard deviations from the sample mean.

i.e. 75% Chebyshev interval around the sample mean. = [tex](\overline{x}-2s,\ \overline{x}+2s)[/tex]

[tex]=(12-2(3),\ 12+2(3))\\\\=(6, 18)[/tex]

Hence, the 75% Chebyshev interval around the sample mean=(6,18)
