The proportion statement is 2/3. The missing angles are CK = 12, GN = 15 and GT = 9

Given that: Polygon ROCK ~  Polygon GNAT.

The symbol ~ means the polygons are similar to each other. That means the ratios of all their corresponding sides are the same. Thus:

CO/AN = 4/6 = 2/3 (This is the proportion statement)

We can also say CK/AT= 2/3 because the ratios of all their corresponding sides are the same

With this, we can determine  the missing sides:

CK/AT= 2/3     where AT = 18

CK/18= 2/3

CK = (18×2)/3 = 12

OR/GN = 2/3    where OR = 10

10/GN = 2/3

2GN = 10×3

2GN = 30

GN = 30/2 = 15

KR/GT = 2/3   where KR = 6

6/GT = 2/3

2GT = 6×3

2GT = 18

GT = 18/2 = 9

Therefore, the proportion statement is 2/3, and the missing angles are CK = 12, GN = 15 and GT = 9

No, they cannot construct a cube from the square pieces of foam board.

A square has four equal sides. When we multiply the length and width of a square to determine its area, we are essentially squaring one of its sides because they are the same.

A=s²

If we already know the area, we can work backward and take the square root to find the side:

√169=√s²

13=s

13 inches is the side length.

The length, breadth, and height of a cube are all equal. These three measurements are multiplied to determine a cube's volume; since they are equal, this essentially equals cubing the side length:

V=s³

The volume is 1728, so we have the following:

1728=s³

We take the cubed root and move backwards:

∛1728=∛s³

12=s

So, In order to construct a cube with the given volume 12 should be length of the side but the length of the square is 13 so it is not possible.

The annual premium of Susie's insurance company apply as a result of accident is $255 for an year. This is because the monthly insurance payment has been increased by $21.25.

What is Health insurance?

Health insurance or the medical insurance is an insurance which covers the whole or a part of the risk of a person which is incurring the medical expenses. Depending upon the health insurance plan, the risk is shared among many individuals.

Main body:

The increase in monthly insurance payment = $21.25

So, the annual increase in the premium amount paid by Susie will be:

Monthly increase in insurance payment × 12

(As there are 12 months in an year)

Based on the given parameters, the amount owed is $10865

The given parameters about the compound interest are

Principal Amount, P = $5300

Interest Rate, R = 8%

Time, t = 6 years

To calculate the amount owed, we make use of the following formula

A = P + CI

Where

Compound interest, CI = P(1 + R)^t - P

So, the equation becomes

A = P + P(1 + R)^t - P

Evaluate the like terms

A = P(1 + R)^t

In this question, the formula is given as

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

Where

n = 12, i.e compounded monthly

Substitute the known values in the above equation

A = 5300 * (1 + 8%/12)^(6*12)

Express 8% as decimal

A = 5300 * (1 + 0.08/12)^(6*12)

Evaluate the sum

A = 5300 * (1.01)^(6*12)

Evaluate the exponent

A = 5300 * 2.05

Evaluate the product

A = 10865

Hence, the value of the amount after 6 years is $10865

Using the given model, we can complete the expression

                       12 + 16 = 4 × (4 + 3).

What are the area of a rectangle and a square?

The area of a rectangle having length "l" and breadth "b" is

                 Area of a Rectangle = l × b.

The area of a square with side "a",

                 Area of a square = side².

Let the given expression be 12 + 16 =  x × (y + x)

For the given figure the area of the square which is displayed in pink portion can be expressed as

                   Area = y²

                      16 = y²

Taking square root on both sides, we get

                      y = 4.

Now for the red part, we get the length of the rectangle i.e., y = 4.

                   Area of a rectangle = length * breadth

                                            12 = 4 * x

                                             x = 3.

The given triangles DEF and LNM are similar "by the SSS similarity postulate"

As given in the question, for LNM:

∠N=90°, LN(base)=5 and MN(prependicular)=3

and for DEF:

∠E=90°, DE(base)=10 and MN(prependicular)=6

Two triangles are similar when all their corresponding angles are congruent.

So far we have ∠N≅∠E=90°

Now, for the remaining angles, we first compare ∠L and ∠D.

From Pythagoras' theorem, we get:

For triangle LNM

[tex]LM^{2}=MN^{2}+LN^{2}\\LM=\sqrt{3^{2}+5^{2}}\\LM=\sqrt{34}[/tex]

For triangle DEF

[tex]DF^{2}=EF^{2}+DE^{2}\\DF=\sqrt{6^{2}+10^{2}}\\DF=\sqrt{136}\\DF=2\sqrt{34}[/tex]

Now we have all sides for both triangles and we compare the ratio of corresponding sides;

Side 1: LN:DE = 5:10 = 1:2

Side 2: MN:FE = 3:6 = 1:2

Side 3: LM:DF = [tex]\sqrt{34}[/tex]:[tex]2\sqrt{34}[/tex] = 1:2

As all three ratios are the same, by SSS similarity postulate, we can deduce that triangles LNM and DEF are similar.

Explanation:

[tex]\frac{3}{4}[/tex] (< = >) [tex]\frac{33}{40}[/tex]

To figure this out, you want both fractions to have the same denominator. So, you would find the GCF (Greatest Common Factor).

The GCF for 4 and 40 would be 40 because 4 * 10 = 40 and 40 * 1 = 40.

To make the whole fraction have the denominator 40, you have to multiply the numerator and the denominator by 10.

[tex]\frac{3}{4} = \frac{30}{40}[/tex]

So,

[tex]\frac{30}{40} < \frac{33}{40}[/tex]

or

[tex]\frac{3}{4} < \frac{33}{40}[/tex]

The end behavior of the function is as x → -∞, f(x) → -∞ and s x → +∞, f(x) → +∞.

The nature of the value when the function parameter gets closer to +∞ and - ∞ is the end behavior of a function. The term with the highest degree determines how a polynomial function will behave in the end.

Look at the polynomial function's leading term to identify its final behavior. The leading term will dominate the graph because it has the highest power and will therefore grow much more quickly than the other terms as x gets very large or very small.

The given function is f(x) = 7x⁷ + 12x⁵ - 6x³ + 2x - 18

120 pints of first mixture and 20 pints of second mixture need to make 140 pints new mixture that 70% pure fruit juice.

Let we have to mix existing mixture in x,y respectively in amount to make the new mix of 70% purity.

Given that the first type is 65% pure.

So the pure juice = 65x/100

Given the second type is 100% pure.

So amount of pure juice in it = 100y/100

So the amount of pure juice in new mix = 65x/100+100y/100 = (65x+100y)/100

So the total amount of new mix = x+y

According to question,

((65x+100y)/100)/(x+y) = 70/100

(13x+20y)/(20x+20y) = 7/10

(13x+20y)/(2x+2y) = 7

13x+20y = 14x+14y

14x-13x = 20y-14y

x = 6y

x:y = 6:1

So we have to mix the existing mixture in 6:1 ratio.

So to make 140 pints of new mix need,

first mix = 140*(6/(6+1)) = 140* (6/7) = 120

second mix = 140*(1/(6+1)) = 140*(1/7) = 20

Hence 120 pints of first mixture and 20 pints of second mixture need to make 140 pints new mixture that 70% pure fruit juice.

The equation of slope intercept form is  y =−4x+24

An intercept is a y-axis point through which the slope of a line passes. It is the y-coordinate of a y-axis point at which a straight line or a curve intersects. This is represented by the straight-line equation y = mx+c, where m is the slope and c is the y-intercept.

Given m = -4 and point)-3, -12)

One way to write a line's equation is in slope-intercept form, which looks like this:

y = mx+b

m = slope

b = y-intercept (where the line crosses the y-axis)

The problem has already been given

m = −4

x=-3

y=-12

Normally, the equation of a line is left with x and y being variables, and m and b having values. Since we do not have a value for b, we will plug all those numbers in and solve.

When those are substituted, the equation should look like this.

-12=(4)(-3)+b

-12=12+b

24=b

So the line's equation would be:

y=−4x+24

And this is your equation graphed. Notice how the line crosses the y-axis at 24, and that the slope is −4, just like the equation says.

Probability of an event = Number of women in class/total number of students in the class

(More to know: probability of an event can be equal to 1 or less than 1.)

Total number of students in the class = 27+32
