(13 points & to get BRAINLIEST, plz give a good explanation so I can improve)

Indications:
Ignore my work for number 1, I need help with number 2. I must submit before 11:59 and it would be really appreciated to get an explanation, not only the answers to the questions.

The answer is 3. The only common factor between the numbers is 3, because 15 is 3 times 5, while 9 is 3 times 3.

Answer:

Greatest common factor: 3

Step-by-step explanation:

Both 15 and 9 have a factor of 3, and that is the biggest number that they share. The answer doesn't have letters in it because y and n are not related.

Answer:

Step-by-step explanation:

y = k x X

7 = k x 2

7/2 = k...............1

hence y = 7/2x (substituting eq 1)

y = 21

therefore, x = 2y/7

x = 2 x 21

         7

x = 2 x 3

x = 6    

The required value of x is 6, when y =21 and y directly varies as x.

A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio.

Given that,

y directly varies as x,

Implies that,

y ∝ x

or y = k x         (1)

When x = 2 and y = 7, from equation (1)

7 = k × 2

k = 7 / 2

To find the value of x when y = 21,

Substitute values of k = 7 /2 and y = 21 in equation (1),

21 = (7 / 2) × x

3 × 2 = x

x = 6

The value of x when y = 21, is 6.

Step-by-step explanation:

Negative numbers are smaller the farther away they are from zero. Positive numbers get bigger the farther away from zero they go.

B.The weather pattern in City 2 is more consistent than the weather pattern in City 1

explanation:

Range and interquartile range (IQR) measures the spread of data. Range measure the overall spread and IQR measures spread in 50% of data.

Range is calculated by differencevof maximum and minimum value whereas IQR is calculated by difference of First quartile and third quartile.

Since, the range and IQR is less for City 2 as compared to City 1.

Thus ,weather pattern of City 2 is more consistent as compared to City 1.

Step-by-step explanation: I did it on my paper and it kind of took a long time

Answer:

1.) x = 30 ; 150°   2.) x = 30 ; 50°  3.) x = 40 ; 122°

Step-by-step explanation:

Each one of the problems revolves around vertical angles. Verticle angles are equal to each other.

1.)

5x = 3x + 60

2x = 60 (Subtracted 3x on both sides.)

x = 30 (Divided 2 on both sides.)

Know that we know the variable's value, time to find the angles.

5(30) = 3(30) + 60

150 = 150

This means the angles are 150°.

2.)

3x - 40 = x + 20

2x - 40 = 20

2x = 60

x = 30

3(30) - 40 = (30) + 20

90 - 40 = 50

50 = 50

This means the angles are 50°.

3.)

5x - 78 = 3x + 2

2x - 78 = 2

2x = 80

x = 40

5(40) - 78 = 3(40) + 2

122 = 122

This means the angles are 122°.

The value of x is 30° and the unknown angle is 150°.

We need to find the unknown angles from the given figure.

The vertical angles theorem or vertically opposite angles theorem states that two opposite vertical angles formed when two lines intersect each other are always equal (congruent) to each other.

From figure 1:

(5x)°=(3x+60)°

⇒5x-3x=60

⇒2x=60

⇒x=30

So, (5x)°=(3x+60)°=150°

From figure 2:

(3x-40)°=(x+20)°

⇒3x-x=60

⇒2x=60

⇒x=30

So, (3x-40)°=(x+20)°=50°

From figure 3:

(3x+2)°=(5x-78)°

⇒5x-3x=78+2

⇒2x=80

⇒x=40

So, (3x+2)°=(5x-78)°=122°

Therefore, the value of x is 30° and the unknown angle is 150°.

Answer:

Step-by-step explanation:

it would stay the same cause it can't be rounded to the hundredths place

The decimal number 113.04 rounded to the nearest hundredths place as 113.04.

The given decimal number is 113.04.

Rounding a number means the process of making a number simpler such that its value remains close to what it was. The result obtained after rounding off a number is less accurate, but easier to use. While rounding a number, we consider the place value of digits in a number.

To round 113.04 to the nearest hundredth consider the thousandths' value of 113.04, which is 0 and less than 5. Therefore, the hundredths' value of 113.04 remains 4.

Therefore, the decimal number 113.04 rounded to the nearest hundredths place as 113.04.

Answer:

10 [tex]\frac{1}{8}[/tex] = [tex]\frac{81}{8}[/tex]

Step-by-step explanation:

Given

(m - 10)(8m - 1) = 0

Equate each factor to zero and solve for m

m - 10 = 0 ⇒ m = 10

8m - 1 = 0 ⇒ 8m = 1 ⇒ m = [tex]\frac{1}{8}[/tex]

Thus sum of roots = 10 + [tex]\frac{1}{8}[/tex] = 10 [tex]\frac{1}{8}[/tex] = [tex]\frac{81}{8}[/tex]

A full circle is 360 degrees so half way would be 180 and since theyre parallel you know that you can use the 55 degrees up top to use in ur equation to find cfe

180-55=125

Can't be 45 because the angle on the other side is smaller than cfe and its 55 degrees and cfe has to be wider than 90 degrees because a right angle is 90 degrees and this angle noticeable goes past 90

Can't be 180 because the whole thing equals 180
