2) What type of angle is 4 and 8?

I What is the special angle pair relationship between < 8 and < 4?

Angle 4 and angle 8 are also alternate interior angles. Alternate exterior angles: Pairs of exterior angles on opposite sides of the transversal. Angle 2 and angle 7 are alternate exterior angles.

3)Twos are generally thoughtful, people-oriented, and caring, while Threes are resourceful, energetic, and determined.

4) Do not use a protractor. Use the properties of straight and vertical angles to help you.

Solution

In a cyclic quadrilateral, opposite angles is supplementary.

=> 3x - 59 + 2x - 1 = 180

=> 5x - 60 = 180

=> 5x = 180 + 60

=> 5x = 240

=> x = 48

Angle A = 2(48) + 4 = 100

Also, A + C = 180

=> C = 180 - 100

=> C = 80

The value of x / y in the given equation will be -2 / 3. The correct option is B.

The new price after being marked up is less than initial price of $100.

The price of sweatshirt after discount = 100 - 40%×100

Converting percentage to fraction

The price of sweatshirt after discount = 100 - (40/100)×100

The price of sweatshirt after discount = 100 - 40

Performing subtraction

The price of sweatshirt after discount = $60

The marked up sale price = 60 + 40%×60

Converting percentage to fraction

The marked up sale price = 60 + (40/100)×60

Cancelling zero and performing multiplication

The marked up sale price = 60 + 24

because supplementary means sum of the angles is 180 degrees.

if the die were loaded so that the face with the 3 on it were twice as likely to come up as each of the other five faces, No , it does not  change the value of p(odd number) .

a) The sample space is the set of all possible outcomes. By definition, the elements of a set should not be repeated. Hence, the sample space S = {1, 2, 3}

However, the sample is not equiprobable because each element has different probabilities.

b) P(odd number) = number of odd digits / number of faces = 4/6=2/3

Note that the odd numbers are 1 (on three faces) and 3 (on one face).

c) The fact the die has been biased does not change the possible outcomes. It only changes the probability of getting any given number.

d) Because the 3-face has been loaded, this probability changes. In fact, it is calculated thus:

Let's assume the probability for 1 or 2 is . Then that of 3 is (because it is twice the others). The sum of probabilities must be 1.

x+x+x+x+x+2x=1

well, seems the Credit Card is the better deal monthly wise, though in the long run is a lot of dough.

A plan which would give Genesis the lowest monthly payment is the monthly payment on a bank loan would be $317.50.

Mathematically, the simple interest earned can be calculated by using this formula:

A = P(1 + rt)

Where: A represents the future value.

P represents the principal or original value.

r represents the interest rate.

t represents the time.

Now Substituting the given parameters into the formula, we have,

A = 9000[1 + (0.09 × 3)]

A = 9000[1 + 0.27]

A = 9000 × 1.27

Future value, A = $11,430.

Next, we will calculate the monthly payment over a period of 36 months as follows:

Monthly payment = Future value/Time

Monthly payment = 11,430/36

Monthly payment = $317.50.

Similarly, we will calculate the compound interest earned on the credit card :

A = 9000[1 + (0.18/12)]⁽¹² ˣ ⁷⁾

A = 9000[1 + 0.015]⁸⁴

A = 9000 × 1.015⁸⁴

A = 9000 × 3.49258954

Future value, A = $31,433.31.

Next, we will calculate the monthly payment over a period of 84 months as follows;

Monthly payment = Future value/Time

Monthly payment = 31,433.31/84

Monthly payment = $372.21.

In this context, A plan which would give Genesis the lowest monthly payment is the monthly payment on a bank loan would be $317.50.

The volume of the pile based on the width, height, and length of the pile can be found to be 1.43 m³

The volume of the pile can be found by the formula:

= Length x Width x Height

From the question, the dimensions of the pile are:

Length = 110 cm

Width = 100 cm

Height = 130 cm

The volume is:

= 110 x 100 x 130

= 1,430,000 cm³

Converted to meters gives:

= 1,430,000 / 1,000,000

= 1.43 m³

Answer:

4 m and 62.5 cm

Step-by-step explanation:

1 meter = 100 cm

So 18m and 50 cm = 18 x 100 + 50 cm = 1850 cm

If it is going to be divided into 4 equal parts, each part = 1850/4 = 462.5 cm

462.5 cm = 462.5/ 100 = 4 m and 0.625 m

0.625m = 0.625 x 100 = 62.5 cm

So each piece is 4 m and 62.5 cm

The height of the arch is about 6.71 feet when measured from its base at a distance of one foot.

This is further explained below.

Generally, An ellipse is a collection of points whose distances from a fixed point (focus) or fixed line (directrix) is constant and less than 1.

Depending on whether the transverse axis is horizontal or vertical, we may construct an equation for the ellipse. The main axis is located along the transverse axis. The ellipse may be represented using the following equations:

[tex]\begin{aligned}&\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1 \\&\frac{(y-k)^2}{a^2}+\frac{(x-h)^2}{b^2}=1\end{aligned}[/tex]

An elliptical arch is described as having a center height of 9 feet and a width of 6 feet. The precise height of the arch from the base has to be determined.

[tex]\frac{(y-k)^2}{a^2}+\frac{(x-h)^2}{b^2}=1[/tex]

The center (h, k) is where the graph is since we centered it at the origin (0,0). We only need to enter the numbers into the equation at this point.

[tex]\begin{aligned}\frac{(y-0)^2}{9^2}+\frac{(x-0)^2}{3^2} &=1 \\\frac{y^2}{81}+\frac{x^2}{9} &=1\end{aligned}[/tex]

Since we divided the arch in half, 0 [tex]\leq[/tex] 9 in this instance. All that is left to do is calculate the arch's height in feet from the base.

The height of 1 foot from each end of the arch must thus be determined. The locations of the arch's ends are x=-3 and x=3. Here, we have a choice between the two. We may choose x=3-1=2 for this. Therefore, all that is left to do is enter x=2 in our usual form and work out the value of y that results.

[tex]\frac{y^2}{81}+\frac{(2)^2}{9}=1[/tex]

y^2+36=81

y^2+36-36=81-36

y=3√5

Therefore, the height of the arch at 1ft from the base is 3 √5ft or approximately 6.71ft

1. The constant of proportionality when Ana runs 3/4 mile in 6 minutes is 0.125.

2. The missing value in the table will be 7.5 miles and 8.75 miles.

It should be noted that the constant of proportionality simply illustrates the ratio of two given values that have a proportional relationship.

1. In this case, Ana runs 3/4 mile in 6 minutes. Therefore, the constant of proportionality will be:

y = kx

where y = distance

x = time

3/4 = 6x

0.75 = 6k

Divide

k = 0.75 / 6

k = 0.125

The constant of proportionality is 0.125.

2. The missing value in the table will be:

y = kx

when x = 60.

y = 60 × 0.125 = 7.5 miles.

y = kx

The mean and the standard deviation for the population of products produced with this process are 2.0 and 0.3329

The population mean is given by

ц = [tex]\frac{L+U}{2}[/tex]

where L and U are the two given boundaries

Here, L = 1.9 and U = 2.1

⇒ ц = [tex]\frac{1.9+2.1}{2}[/tex]

⇒ ц = 2.0

Now, the z value when p =5%, from z table of probability will be

z = -1.645

Standard Deviation denoted by σ is a measure of how dispersed the data is in relation to the mean.

The Standard Deviation can be calculated by the z-score which is given as:

z = (x-ц) / (σ / [tex]\sqrt{n}[/tex])

where z is the Standard score, x is observed value, ц is mean of the sample, σ is standard deviation and n is sample size

-1.645 = (1.9 - 2.0) / (σ / [tex]\sqrt{30}[/tex])

-1.645 × (σ / [tex]\sqrt{30}[/tex]) = -0.1

1.645 × (σ / 5.477) = 0.1

To find the acres of field we can plant per pound of seed, we simply divide both sides of the equation by 107.
