Based on this parallel lines cut by a transversal, the true statements include the following:

B. m∠1 + m∠3 = 180 because they form a straight angle.

C. ∠3 ≅ ∠6 because they are alternate interior angles.

D. ∠1 and ∠6 are supplementary because ∠3 ≅ ∠6 and m∠1 + m∠3 = 180.

Parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and never meet.

The Alternate Interior Angles Theorem states that when two (2) parallel lines are cut through by a transversal, the alternate interior angles that are formed are congruent.

A supplementary angle can be defined as two (2) angles or arc whose sum is equal to 180 degrees (180°).

In conclusion, ∠1 and ∠6 are supplementary angles because ∠3 is congruent to ∠6 and m∠1 + m∠3 = 180 degrees as shown in the image attached below.

The statement that the set {-1, 0, 1} is closed under multiplication, is true and can be proven.

As per the question statement, we are provided with a set {-1, 0, 1}.

We are required to determine if the above mentioned set is closed under multiplication or not.

To solve this question, we simply need to verify if the products of every distinct combination of 2 elements from the concerned set, belongs to the set itself or not, i.e., if we take any two elements "x" and "y", say, from the set "Z", then, [(x*y) ∈ Z].

Here, [tex][(-1)*0]=0[/tex], i.e., belongs to set {-1, 0, 1}.

The number of infected people will reach 568 in approximately 4 weeks

Exponential equations are inverse of logarithmic equation and are represented by the equation below:

y = ab^x

where

a is the base value and x is the exponent

Given the equation that shows the number of infected people from an outbreak of the measles as:

y = 4(6)^t

If the number of infected people reach 568, hence;

568 = 4(6)^t

568/4 = 4(6)^t/4

6^t = 568/4

6^t = 142

Take the natural logarithm of both sides

ln(6^t) = ln142

t = ln142/ln6

There are 63 M&M's in the bag when all of them are added together.

16 out of 63 (16/63) were yellow.

5 out of 21 (5/21) were green. This answer is simplified. The original is 15/63.

1 out of 3 (1/3) were brown. This answer is simplified. The original is 21/63.

11 out of 63 (11/63) were red.

Tip:

To find the fraction of something, put the total on the bottom and the wanted portion on the top.

Example: 5 yellow and 10 red birds were in a cage. Which fraction were yellow?

We put the total of birds (5+10 = 15) on the bottom and the portion wanted ("5 yellow") on the top. The fraction is 5 out of 15 (5/15). This fraction can be simplified because 5 goes into 15 three times (5 x 3 = 15), so divide the fraction 5/15 by 3 to get 1/3. (5 goes into 5 one time.)

Max is going to have more money than Shawn at the end of the seven weeks from the calculations

We would first have to define x to be the point where the money that they have would be equal

This is the week that is referred to as x

Sean would have $20 + $2x

Max would have $5x

When both amounts are equal, we would have sean = max

= $20 + $2x = $5x

Take like terms

20 = 5x - 2x

20 = 3x

divide through by 3

x = 20 / 3

= 6.6667

Remember

In 7 weeks sean = 20 + 2x 7 = 34

max = 5 x 7 = 75

The set which represents whole numbers but are not natural numbers is:{0,1,2,3 }

Given, we have the following sets:

{₋2,₋3,₋4} = Integers

Negative numbers and all entire numbers are both considered integers. A number without a decimal or fractional element is known as an integer, which encompasses both positive and negative numbers, including zero.

{0,1,2,3} = whole numbers

Whole numbers refer to all natural numbers, including zero (0). We are aware that the term "natural numbers" refers to a group of counting numbers beginning with 1, 2, 3, and so forth. Simply said, a collection of numbers that are whole numbers are those that do not contain any fractions, decimals, or even negative integers. There are zeroes and a group of positive integers in it. whereas all positive integers from 1 to infinity are included in the number system, which also contains natural numbers, which are also used for counting. There is no zero included.

{√₋1 , √₋4 , √₋5 }= Irrational numbers

We are aware that the only numbers that cannot be stated in the form of p/q, where p and q are integers and q 0, are real numbers. For instance, the numbers √5, √3, and so on are irrational.

hence we get the set which represents whole numbers but not natural numbers is {0,1,2,,3,4}

I'll use x in place of θ

Let's isolate the sine term and then square both sides

3sin(x) + 4cos(x) = 5

3sin(x) = 5-4cos(x)

(3sin(x))^2 = ( 5-4cos(x) )^2

9sin^2(x) = 25-40cos(x)+16cos^2(x)

9sin^2(x) = 25-40cos(x)+16(1-sin^2(x))

9sin^2(x) = 25-40cos(x)+16-16sin^2(x)

9sin^2(x)+16sin^2(x) = 25-40cos(x)+16

25sin^2(x) = 41-40cos(x)

25(1-cos^2(x)) = 41-40cos(x)

25-25cos^2(x) = 41-40cos(x)

Now let w = cos(x), so we now have the following

25-25w^2 = 41-40w

25w^2-40w+41-25 = 0

25w^2-40w+16 = 0

(5w - 4)^2 = 0

5w-4 = 0

w = 4/5

Therefore cos(x) = 4/5

Use the pythagorean theorem or unit circle to find that if cos(x) = 4/5, then it leads to sin(x) = 3/5. This is exactly because of the 3-4-5 right triangle.

Then lastly,

tan(x) = sin(x)/cos(x)

tan(x) = sin(x)  ÷  cos(x)

tan(x) = (3/5)  ÷  (4/5)

tan(x) = (3/5)  *  (5/4)

tan(x) = (3*5)/(5*4)

tan(x) = 3/4

The simple interest, in two years at the rate of 1.2% is 880

In this case, we must calculate how much interest 2000 would earn compounded yearly over two years at a rate of 1.2.

I = 880 in interest earned

Annually, the system may be evaluated in terms of simple interest.

A = P(rt) for the first year, where r = 1.2 and t = 1.

Therefore;

A = 2000(1.2×1).

A = 2400.

As a result, the revised Principal amount for the second year is 2400.

As a result, A' = 2400 (1.21).

A' = 2880.

As a result, the sum owing after two years is 2880.

However, because the initial principal is $2,000,

The interest is defined as I = A' - P, or I = 2880 - 2000.

I = 880 as a result of interest.

Simple interest is computed as S.I. = P R T, where P = Principal, R = Annual Rate of Interest in %, and T = Time, commonly expressed as the number of years. The interest rate is expressed as a percentage r% and is written as r/100.

The principle is the money borrowed from the bank or invested at the outset. P represents the principal.

Rate: The rate of interest at which the principle amount is handed to someone for a specific period of time; the rate of interest can be 5%, 10%, or 13%, for example. R represents the interest rate.

Time is the length of time for which the primary amount is supplied to someone. T represents time.

The length of one side of the garage originally is 18.17 feet.

The length of one side of the garage now is 22.25 feet.

The percent increase is 22.4%.

A square is a quadrilateral with four sides of equal length. A square has two diagonals of equal length that intersect at right angles.

Given the area of a square, the length of one side can be determined by calculating the square root of the area.

Area of the square = length²

Length of one side of the square = √area

√330 = 18.17 ft

Area of the garage after it was increased : (1 + percentage increase) x initial area

(1 + 0.5) x 330

1.5 x 330 = 495 feet²

Length of the side of the garage after it is increased = √495 = 22.25 feet
