None of the options are sufficient to prove that ABCD quadrilateral is a kite.

what are quadrilaterals ?

Quadrilaterals are closed two-dimensional shapes with four straight sides and four angles. The word "quadrilateral" comes from the Latin words "quadri" which means "four" and "latus" which means "side". Some common examples of quadrilaterals include squares, rectangles, parallelograms, rhombuses, and trapezoids.

Each type of quadrilateral has its own unique set of properties and characteristics. For example, a rectangle has four right angles and opposite sides that are parallel and congruent. A parallelogram has opposite sides that are parallel and congruent, and opposite angles that are congruent. A rhombus has four congruent sides and opposite angles that are congruent.

According to the question:

Option A: OBC and DC being congruent only tells us that OBDC is a parallelogram, but it does not tell us anything about the other pair of adjacent sides, AB and BC.

Option B: OAC and DC being congruent only tells us that OACD is an isosceles trapezoid, but it does not tell us anything about the other pair of adjacent sides, AB and BC.

Option C: OAC and BC being congruent only tells us that OABC is a kite, but it does not tell us anything about the other pair of adjacent sides, AD and DC.

None of the options given are sufficient to prove that ABCD is a kite. To prove that ABCD is a kite that we need to show that two pairs of adjacent sides are congruent.

Therefore, none of the options are sufficient to prove that ABCD is a kite.

Answer:

Angle 1 = 115 degrees

Angle 2 = 65 degrees

Step-by-step explanation:

Angle 1: Same-side interior angle of Line 1

Angle 2: Same-side interior angle of Line 2

We know that the difference between the angles is 50 degrees. Since the angles are supplementary, we can write the equation:

Angle 1 + Angle 2 = 180

Now, we need to express the difference between the angles in terms of Angle 1 or Angle 2. We can choose either angle, so let's express it in terms of Angle 1:

Angle 1 - Angle 2 = 50

We can rewrite this equation as:

Angle 1 = 50 + Angle 2

Now substitute this expression for Angle 1 into the first equation:

(50 + Angle 2) + Angle 2 = 180

Combine like terms:

2Angle 2 + 50 = 180

Subtract 50 from both sides:

2Angle 2 = 130

Divide by 2:

Angle 2 = 65

Now substitute this value back into the equation for Angle 1:

Angle 1 = 50 + Angle 2

Angle 1 = 50 + 65

Angle 1 = 115

Therefore, the angles are as follows:

Angle 1 = 115 degrees

Angle 2 = 65 degrees

The number of regions created when constructing a Venn diagram with three overlapping sets is 8.

In a Venn diagram, each set is represented by a circle, and the overlapping regions represent the elements that belong to multiple sets.

When three sets overlap, there are different combinations of elements that can be present in each region.

For three sets, the number of regions can be calculated using the formula:

Number of Regions = 2^(Number of Sets)

In this case, since we have three sets, the formula becomes:

Number of Regions = 2^3 = 8

So, when constructing a Venn diagram with three overlapping sets, there will be a total of 8 regions formed.

Each region represents a unique combination of elements belonging to different sets.

These regions help visualize the relationships and intersections between the sets, providing a graphical representation of set theory concepts and aiding in analyzing data that falls into multiple categories.

Therefore, the correct answer is 8.

Car A: 3x + 6

Step-by-step explanation:

total: 7 (x+2)

Measurements need to be made every \(\frac{1}{2}\)times a month to find an overestimate and an underestimate for the number of pollutants that escaped during the first six months which differ by exactly 1 ton from each other.

Let's assume that measurements are made every 'x' time period. Then, the total number of measurements made in 6 months would be \(6/x\). Let's consider the scenario where an overestimate of the quantity of pollutants is made. In this case, the actual quantity of pollutants would be less than the estimated value. Let's assume the overestimate is 'O' tons.

Similarly, in the scenario where an underestimate is made, let's assume the actual quantity of pollutants is greater than the estimated value by 'U' tons.

Given that the difference between the overestimate and underestimate is 1 ton, we can write:\(O - U = 1\)

Now, we know that the total amount of pollutants that escaped during the first six months is constant. Let's assume the actual value of the quantity of pollutants that escaped during the first six months is 'Q' tons. Then, we can write\(Q = O + U + E\)

Here, E represents the estimation error, which is the difference between the actual quantity of pollutants that escaped and the estimated value. Since the overestimate is greater than the actual value, E is negative. Similarly, since the underestimate is less than the actual value, E is positive.

We can rewrite the above equation as:\(E = Q - O - U\)

Substituting the value of O - U = 1, we get:\(E = Q - (O + U)\)

We need to find the value of 'x' such that the absolute value of E is exactly 1 ton.

Let's assume that the estimated value of Q is equal to the actual value of Q. In this case, we can write:\(Q = 2E\)

Substituting the value of E, we get:\(Q = 2(Q - (O + U))\)

Simplifying this, we get:\(O + U = Q/2\)

Substituting the value of Q = 12 (since we are considering the first 6 months), we get:\(O + U = 6\). Since we know that \(O - U = 1,\) we can solve for O and U to get:

\(O = 3.5U = 2.5\)

Now, substituting the values of O and U, we get:\(E = Q - (O + U) = 6 - (3.5 + 2.5) = 0\)

This implies that the estimated value of Q is equal to the actual value of Q, and there is no estimation error.

Using the elimination method, the price of one t-shirt is $30 and one key-chain is $11.

In the given question, Elizabeth's family went to NYC for their vacation.

At the gift shop on Liberty Island, Valerie bought three t-shirts and four key chains for $134, and Jennifer bought four t-shirts and five key chains for $175.

We have to find the price of each item.

Let the price of one t-shirt = $x

Let the price of one Key chain = $y

According to question

Price of three t-shirts and four key chains = $134

So the equation is

3x + 4y = $134……………….(1)

Also,

Price of four-shirts and five Key chains = $175

So the equation is

4x+5y = $175……………………..(2)

Now solving the equation using the elimination method.

Multiply Equation (1) by 5 and Equation (2) by 4, we get

15x+20y = 670....................(3)

16x+20y = 700......................(4)

Subtract equation 4 and 3, we get

x = 30

Now put the value of x in equation 1,

3*30 + 4y = $134

90+4y=$134

Subtract 90 on both side, we get;

4y = 44

Divide by 4 on both side, we get;

y = 11

Hence, the price of one t-shirt is $30 and one key-chain is $11.

Answer:

87.96 square inches

Step-by-step explanation:

The soup can is a cylinder, and we can find how many square inches the label will take up by finding the lateral surface area

Use the formula, LA = 2\(\pi\)rh

The diameter is 4 inches, so the radius is 2 inches

Plug in the radius and height into the formula, and solve:

LA = 2\(\pi\)rh

LA = 2\(\pi\)(2)(7)

LA = 28\(\pi\)

= 87.96

So, the label will take up approximately 87.96 square inches

The equation of the vectors are

35. y = (-1/2)x + 2

36. y = (1/2)x + 5/2

37. y = 2x + 3

38. y = (2/3)x - 52/3

Exercise 35:

P(2, 1)

v = i + 2j

To find the equation of the line passing through P and perpendicular to v, we need to determine the slope of the line. The slope of a line perpendicular to a vector is the negative reciprocal of the slope of the vector.

The vector v = i + 2j has a slope of 2/1 = 2. The negative reciprocal of 2 is -1/2. Therefore, the slope of the line perpendicular to v is -1/2.

Using the point-slope form of a line, we can write the equation of the line passing through P as follows:

y - y₁ = m(x - x₁)

Substituting the values of P(2, 1) and the slope (-1/2), we get:

y - 1 = (-1/2)(x - 2)

Simplifying the equation, we have:

y - 1 = (-1/2)x + 1

y = (-1/2)x + 2

Exercise 36:

P(-1, 2)

v = -2i - j

The slope of the vector v = -2/1 = -2. The negative reciprocal of -2 is 1/2.

Using the point-slope form, we can write the equation of the line passing through P(-1, 2) as:

y - 2 = (1/2)(x + 1)

Simplifying the equation, we have:

y - 2 = (1/2)x + 1/2

y = (1/2)x + 5/2

Exercise 37:

P(-2, -7)

v = -2i + j

The slope of the vector v = 1/(-2) = -1/2. The negative reciprocal of -1/2 is 2.

Using the point-slope form, the equation of the line passing through P(-2, -7) is:

y - (-7) = 2(x - (-2))

Simplifying the equation, we have:

y + 7 = 2(x + 2)

y = 2x + 3

Exercise 38:

P(11, 10)

v = 2i - 3j

The slope of the vector v = -3/2. The negative reciprocal of -3/2 is 2/3.

Using the point-slope form, the equation of the line passing through P(11, 10) is:

y - 10 = (2/3)(x - 11)

Simplifying the equation, we have:

y - 10 = (2/3)x - 22/3

The total number of tasks Terrence completed. By substituting the value of 'x' with the number of tasks Terrence completed

The factor 'x' in the expression '90x - 20' represents the total number of tasks that Terrence completed in the game.

To understand why, let's break down the given information. It states that Shelly and Terrence completed a different number of tasks. Shelly earned 90 points on each task, so the total number of tasks she completed is not represented by 'x'.

On the other hand, Terrence's total points were 20 less than Shelly's total. This means that Terrence's total points can be calculated by subtracting 20 from Shelly's total points. Since Shelly earned 90 points on each task, her total points would be 90 multiplied by the number of tasks she completed.

So, the expression '90x - 20' represents Terrence's total points in the game, where 'x' represents the total number of tasks that Terrence completed. By substituting the value of 'x' with the number of tasks Terrence completed, we can calculate his total points.

Therefore, the correct answer is: The total number of tasks Terrence completed.
