the sum of the 3 angles in a triangle is 180°

the third angle in both diagrams is right , that is 90° as they are the angle in a semicircle.

sum the 3 angles and equate to 180

90 + 16x + 40 + 11x - 4 = 180

27x + 126 = 180 ( subtract 126 from both sides )

27x = 54 ( divide both sides by 27 )

x = 2

90 + 6x + 18 + 3x + 27 = 180

9x + 135 = 180 ( subtract 135 from both sides )

9x = 45 ( divide both sides by 9 )

x = 5

A rope that is 6 meters long will be cut into 24 pieces that are all of the same
length. What will be the length of each piece, in centimeters?

Answers

Answer: I would say 4 centimeters

Step-by-step explanation: Well if 24 divided by 6 equals 4 then I would say 4

Based on the length of the rope and the number of pieces it is to be cut into, the length of each piece will be 25 cm long.

First covert the length of the rope to centimeters:

= 6 x 100

= 600 cm

The length of each piece will be:

= Length of rope / Number of pieces

= 600 / 24

= 25 cm

In conclusion, each piece will be 25 cm long.

Bromine is a diatomic molecule since it is typically found in groups of two.

What is the symbol to represent a chemical compound?

An element's one- or two-letter identification is known as a chemical symbol. O for oxygen, Zn for zinc, and Fe for iron are a few instances of chemical symbols. Symbols always start with a capital letter. Lowercase letters are used for the second letter in symbols with two letters.

A subscript appears after the atom to indicate how many of each kind there are. There is no number written if there is just one atom. The number is given as a subscript after the atom if there are multiples of a particular kind of atom.

Br represents the bromine. Bromine is a diatomic molecule and always needs to be bounded to something. Thus it is bounding to itself.

The expression for the perimeter of a square will be p = 4s.

How to calculate the perimeter?

The perimeter of a figure of shape can be gotten the total length of the boundary which the figure or the shape has. it's gotten by adding all the length that the shape has.

It should be noted that a square has four equals sides. The expressions for the perimeter of a square will be:

p = 4 × s.

p = 4s

where s = number of sides.

p = perimeter

For example if the side is 2cm. The perimeter will be calculated by multiplying 4 by the value of the sides. In this case, this will be calculated as:

= Value of sides × 4

= 2 × 4

1.The income of man increase in the ratio 7 : 8 . If the increase in his income is rs 4500 per month find his new income.

2.The ages of two sister are in the ratio 7 : 5 if the age of elder sister is 15 years 9 months, what is the age of younger sister.

Answers

The new income is new income.

Rs. 36000 per month. 6 years and 6 months.

What is the new income.?

Generally, To find the new income of the man, we can use the formula: New Income = Original Income + Increase in Income

Since the ratio of increase in income is 7:8, we can assume the original income to be 7x and the new income to be 8x.

The increase in income is given as Rs. 4500 per month, so we can set up the equation as:

8x = 7x + 4500

By solving for x, we get that

x = 4500.

Therefore, the new income of the man is

8x = 8 * 4500

= Rs. 36000 per month.

The ages of the two sisters are in the ratio 7:5. If the elder sister is 15 years 9 months old, we can assume her age in months to be

15*12 + 9 = 189 months.

Let's assume x be the age of younger sister in months.

So, according to the ratio 7:5, we can set up the equation as:

x = (5/12)*189

By solving this equation we get

x= 78.75 months, which is roughly 6 years and 6 months.

x = 11

Step-by-step explanation:

The two angles are consecutive interior angles so they add up to 180

13x -26 + 5x + 8 = 180

13x + 5x -26 + 8 = 180

18x - 18 = 180
18x = 180 + 18

18x = 198

x = 11

Answer:

y = 45/2

Step-by-step explanation:

Given:

y = 4x - 1 1/2

find the value of y when x=6

y = 4x - 1 1/2

Substitute x = 6 into the equation

y = 4(6) - 1 1/2

y = 24 - 1 1/2

** 1 1/2 = 3/2

y = 24 - 3/2

y = (48-3) / 2

y = 45/2

y = 45/2 when x = 6

Is 3 3 an additive inverse?

Answers

3 and -3 are additive inverses because 3 + (-3) = 0.

Therefore, -3 is the additive inverse of 3.

Additive Inverse:

The additive reciprocal/ Inverse of a number is its inverse. When a number is added to the additive reciprocal, both numbers sum to zero. A simple rule is to change positive numbers to negative numbers and vice versa. We know that 3+ (-3) =0. So -3 is the additive reciprocal of 3, and 3 is the additive reciprocal of -3.

If the sum of two real numbers is 0, each real number is said to be the additive reciprocal of the other real number. Therefore, R + (-R) = 0. where R is a real number. R and -R are the additive reciprocals of each other. Example: 3/4 + (-3/4) = 0. where 3/4 is the additive reciprocal of -3/4 and vice versa. This is an example of the additive reciprocal of a fraction.

We have room temperature water in a bucket. Adding 1 liter of hot water raises the temperature of the entire bucket by a certain amount. Then add another liter of cold water. Opposite temperature water in the bucket will cancel out, resulting in a bucket of room temperature water. The same rules apply when taking the additive reciprocal of a number. The additive inverse property applies to both real and complex numbers.
