For what values of x and y must each figure be a parallelogram?
Need help please, and explanation.

Answers

Answer 1

Answer:

y = 30

x = 60

Step-by-step explanation:

4y and 2y are consecutive angles, which means they are equal to 180° when added together

that is the same with x and (5x - 180)

to solve, you set the equations to 180

solving:

4y + 2y = 180

6y = 180

y = 30

x + 5x - 180 = 180

6x = 360

x = 60

Write two expressions for the perimeter of a square explain what information is in one of your expression that is not in the other

Answers

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

= 8cm

if AB||EF and EF||CD, then find the value of x.

Answers

Answer:

x = 40°

Step-by-step explanation:

∠ FEC and ∠ ECD are same- side interior angles and sum to 180° , that is

150° + y = 180° ( subtract 150° from both sides )

y = 30°

∠ BCD and ∠ ABCare alternate angles and are congruent , so

x + y = 70° , that is

x + 30° = 70° ( subtract 30° from both sides )

x = 40°

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.

Help me please I don't know it

Answers

Answer:

Step-by-step explanation:

Method 1(Algebra):

m - 14 = 51

Add 14 to both sides of the equation.

m - 14 + 14 = 51 + 14

Combine like terms.

m = 65

Method 2:

m - 14 = 51

Move negative fourteen(- 14) to the other side of the equation. Because we moved it, it is now positive fourteen( + 14)

m = 51 + 14

Combine like terms.

m = 65

What is the diameter of B?
With explanation. No links.

Answers

B = (5/9)A
C = (1/2)(A+B)
C = (1/2)(A+(5/9)A)
C=(5/18)A

A + B + C = 91
A + (5/9)A + (5/18)A = 91

(33/18)A = 91

A = 49 + 7/11

B = (5/9)A

B = (5/9)(539/11)

If you simplify(x^3/x/x)^3, what power rules do you need to simplify it? a. Addition Rule and Power of a Power Rule b. Subtraction rule and Power of a Power. c. Division Rule and Power of a Power Rule d. Power of a Product Rule and Power of a Power Rule e. None of these choices

Answers

Answer:

. c. Division Rule and Power of a Power Rule

Step-by-step explanation:

(x^3/x/x)^3

=(x³/x/x)³

First we need to solve the brackets. Anything written in the fraction form a/b/c can be written as a*c/b.

Similarly (x³/x/x)³ can be written as (x*x³/x)³

Solving further the x can be cancelled by x leaving x³ behind.

(x³)³

Now applying the Power of a Power Rule

x³*³= x⁹

First the division rule and then the power rule is applied.

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.

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.
