Answer:

The correct options are B, C and D.

Step-by-step explanation:

It is given that the figure is a Japanese art of paper folding. It means the figure have many lines of symmetry (i.e., AK, IO, CM and NF).

From the figure it is clear that HV is larger than GW, so segment HV and GW are not pairs of congruent segments.

Therefore option A is incorrect.

[tex]\overline{IJ}\cong \overline{LM}[/tex]        (AK is line of symmetry)

[tex]\overline{AB}\cong \overline{AP}[/tex]        (AK is line of symmetry)

[tex]\overline{BC}\cong \overline{PO}[/tex]        (AK is line of symmetry)

Therefore the correct options are B, C and D.

From the figure it is clear that PO is smaller than ON, so segment HV and GW are not pairs of congruent segments.

Therefore option E is incorrect.

The ratio for the expression "4 added to the difference of d minus 3" can be represented as: (d - 3) + 4.

Expression: "The difference of d minus 3"

This means subtracting 3 from d:

d - 3

Expression: "4 added to the difference of d minus 3"

Add 4 to the result of the previous expression:

(d - 3) + 4

This gives us the entire expression "4 added to the difference of d minus 3.":

(d - 3) + 4

Combine like terms:

d + 1

Therefore, the simplified form of the given expression is (d + 1).

Answer:

Step-by-step explanation:

The question is asking for a system of equations, which make explanations easy. :)

Define the variables. Setting [tex]x[/tex] to the number of clubhouse seats sold and [tex]y[/tex] to the number of grandstand seats sold will be sufficient. The "let statement[s]" will be:

The number of equations shall be no less than the number of variables for the solution to be unique. There are two variables. It will take at least two equations to find a unique solution.

Everyone at the race need a seat. The number clubhouse seats plus the number of grandstand seats shall be the same as the number people at the race. There were 36,000 people. Therefore the first equation shall be:

[tex]x + y = 36000[/tex].

Every clubhouse seat will add $12.00 to the receipt. [tex]x[/tex] clubhouse seats will add $[tex]12\;x[/tex] to the receipt. Similarly, [tex]y[/tex] grandstand seats will add $[tex]5\;y[/tex] to the receipt. The two values shall add up to $250,000.

Drop the dollar sign to get the second equation:

[tex]12\;x +5\;y =250000[/tex].

Hence the system:

[tex]\displaystyle \left\{\begin{aligned}& x + y = 36000 && \textcircled{\raisebox{-0.9pt}1}\\ & 12\;x + 5\;y = 250000 && \textcircled{\raisebox{-0.9pt}2}\end{aligned} \phantom{\small credit for the raisebox hack: tex[dot]stackexchange[dot]com/questions/7032/good-way-to-make-textcircled-numbers}[/tex].

Solve this system.

The first non-zero coefficient in equation [tex]\textcircled{\raisebox{-0.9pt}1}[/tex] is already one. That's the coefficient for [tex]x[/tex]. Use multiples of equation [tex]\textcircled{\raisebox{-0.9pt}1}[/tex] to get rid of [tex]x[/tex] in other equations (equation [tex]\textcircled{\raisebox{-0.9pt}2}[/tex] in this case.)

[tex]-12[/tex] times equation [tex]\textcircled{\raisebox{-0.9pt}1}[/tex] is

[tex]-12 \;x - 12\;y = -432000[/tex].

Add [tex]-12\times \textcircled{\raisebox{-0.9pt}1}[/tex] to [tex]\textcircled{\raisebox{-0.9pt}2}[/tex] to get:

[tex]0\;x + -7\;y = -182000[/tex].

Divide both sides by -7 to get:

[tex]y = 26000[/tex].

Add -1 times this equation to equation [tex]\textcircled{\raisebox{-0.9pt}1}[/tex] to get:

[tex]x = 10000[/tex].

That is:

[tex]\displaystyle \left\{\begin{aligned}&x = 10000\\&y = 26000\end{aligned}[/tex].

In other words,

ANSWER

(C) y

EXPLANATION

We have two equations:

The first one is

[tex]x + y = z...(1)[/tex]

The second equation is

[tex]y - z = x...(2)[/tex]

Let us make z the subject of this second equation:

[tex] \implies \: -x +y = z...(3)[/tex]

We now add equation (1) and (3) to get:

[tex](-x + x) + (y + y) = z + z[/tex]

We simplify to get:

[tex]0+2y= 2z[/tex]

[tex]2y= 2z[/tex]

Divide throu by 2.

[tex] \frac{2y}{2} = \frac{2z}{2} [/tex]

[tex]y= z[/tex]

[tex] \therefore \: z = y[/tex]

The correct answer is C

Step-by-step answer:

Given:

5% annual interest (APR)

compounded daily

Principal = 500

Solution:

Since it is compounded daily, we first calculate the

daily rate =  5% / 365 = 0.05/365

After one year,

future value

= 500 ( 1 + 0.05/365)^365

= 525.634 (to the tenth of a cent)

note: sometimes a year is considered to be rounded to 360 days, or 366 days for a leap year, but there is practically no difference in the results for this problem.

Final answer:

To calculate the future value of a $500 deposit with a 5% annual interest rate compounded daily for one year, we use the compound interest formula. The resulting amount is approximately $525.64.

Explanation:

To calculate the value of a $500 deposit in a credit union that pays 5% annual interest compounded daily, we will use the formula for compound interest:

A = P(1 + (r/n))^(nt)

Where:

A = the amount of money accumulated after n years, including interest.

P = the principal amount (the initial amount of money).

r = the annual interest rate (decimal).

n = the number of times that interest is compounded per year.

t = the time the money is invested or borrowed for, in years.

Using the given information:

P = $500

r = 5% or 0.05 (as a decimal)

n = 365 (since the interest is compounded daily)

t = 1 year

Substituting the values into the formula:

A = 500(1 + (0.05/365))^(365*1)

After calculating, we get:

A ≈ $525.64

Therefore, the value of the $500 deposit at the end of one year with daily compounding at a 5% annual interest rate is approximately $525.64.

Answer:

B

Step-by-step explanation:

Ratio of sides = a : b , then

Ratio of volumes = a³ : b³

Here the ratio of volumes = 27 : 729, hence

Ratio of sides = [tex]\sqrt[3]{27}[/tex] : [tex]\sqrt[3]{729}[/tex] = 3 : 9

Ratio of sides = 3 : 9 = 1 : 3 ← in simplest form

Hence sides of larger cube are 3 times sides of smaller cube → B

Answer:

[tex]x=19[/tex]

Step-by-step explanation:

We have the following equation

[tex]3(x+6)=5(x-4)[/tex]

Notice that in this equation the variable that we want to find is x.

Then the equation for the variable x must be solved

After applying the distributive property and simplifying the equation Maria obtained the following result

[tex]19=x[/tex]

This is the same as:

[tex]x=19[/tex]

That means that the value of x for which equality is met is [tex]x = 19[/tex]. Therefore the solution of the equation is [tex]x = 19[/tex]

The third quartile is:

[tex]Q_3=29[/tex]

Step-by-step explanation:

First organize the data from lowest to highest

4, 5, 10, 12, 14, 16, 18, 20, 21, 21, 22, 22, 24, 26, 29, 29, 33, 34, 43, 44

Notice that we have a quantity of n = 20 data

Use the following formula to calculate the third quartile [tex]Q_3[/tex]

For a set of n data organized in the form:

[tex]x_1, x_2, x_3, ..., x_n[/tex]

The third quartile is  [tex]Q_3[/tex]:

[tex]Q_3=x_{\frac{3}{4}(n+1)}[/tex]

With n=20

[tex]Q_3=x_{\frac{3}{4}(20+1)}[/tex]

[tex]Q_3=x_{15.75}[/tex]

The third quartile is between [tex]x_{15}=29[/tex] and [tex]x_{16}=29[/tex]

Then

[tex]Q_3 =x_{15} + 0.75*(x_{16}- x_{15})[/tex]

[tex]Q_3 =29 + 0.75*(29- 29)\\\\Q_3 =29[/tex]

y=4

the values of x changes while the y doesn't so it's y=4

Answer:

[tex]y=4[/tex]

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

[tex]y=mx+b[/tex]

Where "m" is the slope and "b" is the y-intercept.

The equation of the line in Standard form is:

 [tex]Ax + By =C[/tex]

Where A, B, and C are integers.

We can find the slope of this line with this formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Given the points K(6, 4) and L(-6, 4), we get:

[tex]m=\frac{4-4}{-6-6}=0[/tex]

Substituting the value of "m" and the coordinates of any point on the line into the equation and solving for "b", you get:

[tex]4=0(6)+b\\b=4[/tex]

Therefore, the equation of this line is:

[tex]y=4[/tex]

Answer:

$7 000 was loaned at 10 % and

$10 500 was loaned at 14 %

Step-by-step explanation:

                 Let x = amount loaned at 10 %

Then 17 500 - x = amount loaned at 14 %

                0.10x = interest on 10 % loan

0.14(17 500 - x) = interest on 14 % loan

          2170.00 = total interest

[tex]\begin{array}{rcl}0.10x + 0.14(17 500 - x) & = & 2170.00\\0.10x + 2450 - 0.14x & = & 2170.00\\2450 - 0.04x & = & 2170.00\\-0.04x & = & -280\\\\x & = & \dfrac{-280}{-0.04}\\\\x & = & \mathbf{7000}\\\\\end{array}[/tex]

$7000 was loaned at 10 % and

$10 500 was loaned at 14 %

Check:

\[tex]\begin{array}{rcl}0.10\times 7000 + 0.14(17 500 - 7000) & = & 2170\\700 + 0.14(10 500) & = & 2170\\700 + 1470 & = & 2170\\2170 & = & 2170\\\end{array}[/tex]

Answer: Area of Square = 81m^2

Step-by-step explanation:

To find the area of a square you just need to know the side length on one side, and since we know that the perimeter is 36, and all sides of a square are equal we can divide 36/4, to get 9 is your side length.

Now to actually find the area you can just square your side length, so basically 9x9, which gives you 81, your answer!!

Answer:

Area = 81m^2

Step-by-step explanation:

Square has 4 equal sides so 36/4 =  9

9(9) = 81

Hope this helps :)

Answer:

Option B: 49 square units.

Step-by-step explanation:

The irregular polygon consists of a rhombus a square.

Area of rhombus = 0.5*(product of diagonals).

Area of square = length * length = l^2.

The diagonals of the rhombus measure 8 units and 6 units respectively. The diagram shows the length of half of the diagonals, so doubling both the lengths gives us the required lengths. The side of the square measures 5 units. Substituting all the information in the formula:

Total Area = Area of rhombus + Area of square.

Total Area = 0.5*8*6 + 5^2.

Total Area = 24 + 25

Total Area = 49 square units.

Therefore, Option B is the correct answer!!!

Answer: You will need 18 containers of 1-quart to fill the gearbox with 16.3 liters of oil.

Step-by-step explanation:

Knowing that you have 1-quart containers, you need to make the conversion from quarts to liters. This is:

[tex]1\ quart=0.946\ liters[/tex]

Now, since the gearbox holds 16.3 liters of oil, you can divide the volume of oil the gearbox holds by the volume of a container  (which is 0.946 liters or 1-quart) to calculate how many containers of 1-quart you will need to fill the gearbox with 16.3 liters of oil.

 [tex]number\ of\ containers=\frac{16.3\ liters}{0.946\ liters}=17.2[/tex]

Based on the result, you will need 18 containers of 1-quart to fill the gearbox with 16.3 liters of oil.

You will need 17 one-quart containers of oil to fill the 16.3-liter gearbox.

To determine how many 1-quart containers of oil you will need to fill the 16.3-liter gearbox, we can convert the 16.3 liters to quarts by using the conversion factor of 1 liter = 1.05668821 quarts. So, 16.3 liters would be approximately 17.229 quarts. Since each 1-quart container holds exactly 1 quart of oil, you will need 17 of the 1-quart containers to fill the gearbox with 16.3 liters of oil.

The word "climbing" has 8 letters, so there are [tex]8![/tex] permutations of all the letters.

Nevertheless, the letters are not unique: there are 2 I's. This means that, if we start from a given word and we exchange the positions of the two I's, we'd still get the same word. So, we have to divide the number of possible permutations by [tex]2![/tex], because for any given permutation there are two identical words, given by the interchange of the I's.

So, the number of possible words is

Answer:

see explanation

Step-by-step explanation:

Given

f(x) = 3x² - 6x + 1

To express in vertex form

f(x) = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Use the method of completing the square

The coefficient of the x² must be 1, so factor out 3

f(x) = 3(x² - 2x) + 1

add/subtract ( half the coefficient of the x- term )² to x² - 2x

f(x) = 3(x² + 2(- 1)x + 1 - 1) + 1

     = 3(x - 1)² - 3 + 1

     = 3(x - 1)² - 2 ← in vertex form

with vertex = (1, - 2)

To determine if vertex is a max/ min

• If a > 0 then minimum

• If a < 0 then maximum

here a = 3 > 0 ⇒ minimum at (1, - 2)

The minimum value is the y- coordinate of the vertex, that is

minimum value = - 2
