the parallelogram in the image is a rectangle. There are two ways to tell this from the information given: The diagonals of a rectangle bisect each other, but the diagonals in the image do not bisect each other. The opposite sides of a rectangle are congruent, and the sides of the parallelogram in the image appear to be congruent.
The diagonals are perpendicular. In the image, one of the answer choices states that the diagonals are perpendicular, and this is the key giveaway. Diagonals of a rectangle are always perpendicular, so if a parallelogram has perpendicular diagonals, it must be a rectangle.
The diagonals are congruent. Another answer choice states that the diagonals are congruent. While this is also true for rectangles, it is not true for all parallelograms. So, while not all parallelograms with congruent diagonals are rectangles, all rectangles do have congruent diagonals.
Therefore, based on the information given in the image, we can conclude that the parallelogram is a rectangle.
Here are some additional properties of rectangles that you may find helpful:
Opposite sides of a rectangle are equal and parallel.
Opposite angles of a rectangle are equal.
All angles of a rectangle are right angles.
The diagonals of a rectangle bisect each other.

What are the characteristics of trapezoid ?
Answers
Answer:
"A trapezoid is a quadrilateral with two parallel sides and, usually, two nonparallel sides."
Step-by-step explanation:
"A trapezoid is a quadrilateral with two parallel sides and, usually, two nonparallel sides. A quadrilateral is a geometric shape that has four sides. Some specialized types of trapezoid are the parallelogram and the isosceles trapezoid.
The two parallel sides of a trapezoid are its bases while the legs are the nonparallel sides. Geometric analysis of a trapezoid includes calculating the height, median and area. The height of a trapezoid is a line segment that runs perpendicular to the bases. The median, or mid-segment, is a line that is parallel to the bases and connects the midpoints of each leg. The area is calculated with a formula using the lengths of each base and the height.
A parallelogram is usually defined as a trapezoid, although it has two pairs of parallel sides instead of just one. An isosceles trapezoid has congruent base angles and equal leg lengths."
A trapezoid is a four-sided polygon with one pair of parallel sides. Its key characteristics include parallel sides, supplementary adjacent angles, and specific area calculation. The median connects the midpoints of the legs, with a length that averages the bases.
A trapezoid is a four-sided polygon, also known as a quadrilateral, with one pair of opposite sides parallel. These parallel sides are known as the bases of the trapezoid, while the other two sides are called the legs.
Key Characteristics:
Parallel Sides: The most defining feature of a trapezoid is that it has exactly one pair of parallel sides.Angle Properties: The angles adjacent to each leg are supplementary, meaning they add up to 180 degrees.Area Calculation: The area of a trapezoid can be calculated using the formula A = 1/2 × (Base1 + Base2) × Height, where Base1 and Base2 are the lengths of the parallel sides, and Height is the perpendicular distance between them.Median: The median (or midsegment) of a trapezoid is a line segment that connects the midpoints of the legs, and its length is the average of the lengths of the bases.These characteristics are essential for identifying and working with trapezoids, especially in various mathematical problems and geometric constructions.

Find the surface area of the right square pyramid. Round your answer to the nearest hundredth. A 117.66 yd^2 B. 123.21 yd^2 C. 145.75 yd^2 D. 182.04 yd ^2
Answers
Answer: OPTION C
Step-by-step explanation:
Use the following formula:
[tex]SA=\frac{pl}{2}+B[/tex]
Where p is the perimeter of the base, l is the slant height and B is the area of the base.
The perimeter is:
[tex]p=4*s=4*5.3yd=21.2yd[/tex]
Where s is the side lenght
The slant height is given:
[tex]l=11.1yd[/tex]
The area of the base is:
[tex]B=s^2=(5.3yd)^2=28.09yd^2[/tex]
Where s is the side lenght
Substitute values. Then, the result is:
[tex]SA=\frac{(21.2yd)(11.1yd)}{2}+28.09yd^2)=145.75yd^2[/tex]
Answer:
The correct answer option is C. 145.75 yd^2.
Step-by-step explanation:
We are given a diagram of a right square pyramid with a slant height 11.1 yd, and base edge length 5.3 yd.
We know that the surface area of a right square pyramid is given by:
[tex]\frac{PI}{2} +B[/tex]
where P = perimeter of the base, I = slant height and B = base area.
Perimeter of base = [tex]4 \times 5.3[/tex] = 21.2 yd^2
Base Area = [tex]5.3^3[/tex] = 28.09 yd^2
Surface area of right square pyramid = [tex]\frac{21.2 \times 11.1 }{2} + 28.09[/tex] = 145.75 yd^2
In 2005, there were 12,300 students at college A, with a projected enrollment increase of 500 students per year. In the same year there were 18,550 students at college B with a projected enrollment decline of 750 students per year. According to these projections, when will the colleges have the same enrollment? What will the enrollment in each college at that time?
Answers
Answer: 5 years
14,800 students enrolled
Step-by-step explanation:
Let x represent the number of years and
Let y represent the number of students enrolled
College A: y = 12,300 + 500x
College B: y = 18,550 - 750x
Use substitution Method to solve:
12,300 + 500x = 18,550 - 750x
+750x +750x
12,300 + 1250x = 18,550
-12,300 -12,300
1250x = 6250
x = 5
Input x = 5 into one of the equations to solve for y.
y = 12,300 + 500x
= 12,300 + 500(5)
= 12,300 + 2500
= 14,800

Answers
The repeated subtraction of 8 from 32 until reaching 0 can be represented by the division equation 32 ÷ 8 = 4, showing the number of times 8 is subtracted from 32.
Explanation:The student is performing repeated subtraction of the same number, which can also be represented by a division equation. The repeated subtraction mentioned:
32 take away 8 is 2424 take away 8 is 1616 take away 8 is 88 take away 8 is 0Shows that 32 is being subtracted by 8 until it reaches 0, and this process happens four times. Thus, we can convert this series of subtractions into a division equation: 32 ÷ 8 = 4. This equation means that you can subtract 8 from 32 four times before reaching zero, which is equivalent to dividing 32 by 8.

30000 equals how many ones
Answers
The number 30,000 is made up of 30,000 individual ones. This basic mathematical concept helps understand the scale of numbers and aid in quick approximations. It can be compared to estimating powers of 10 for mental calculations.
Explanation:The question '30000 equals how many ones' can be interpreted as asking how many single units there are in 30,000. This is a basic math concept dealing with place value and integer understanding. Each individual unit is a 'one', and therefore, in 30,000, there are 30,000 of these individual units, each one contributing to the total value of the number. In other words, 30,000 is comprised of 30,000 ones.
To relate this to practical applications, consider the example where the square root of 10 is roughly estimated as 3, because 3³ (which is 3 x 3 x 3) equals 27, which is near to 10² (100), giving us an approximation that is useful for mental calculations. Similarly, the basic concept of powers of 10 can be applied here, with 10³ being 1,000, hence 30 x 10³ being 30,000. So, when you're working with large numbers like 30,000, knowing that it is made up of 30,000 ones can help you understand its scale and make quick approximations in everyday calculations.
How do mathematical graphs help us better understand our world
Answers
Answer:
because they help us better analyze data
Step-by-step explanation:
we can see a lot of data on one small thing such as a graph, so we can easily graph data from many years on one graph
Graphs in mathematics help us visually represent equations and display data, allowing us to understand patterns, trends, and relationships between variables.
Explanation:Graphs are an important tool in mathematics as they help us better understand our world by visually representing equations and displaying data. Graphs can show the relationship between different variables, such as in a line graph where one variable is plotted on the horizontal axis and another on the vertical axis. They can also represent data using bar graphs or pie graphs, which help us compare and interpret numerical information.
For example, if we want to analyze the temperature changes throughout a year, we can plot the temperature on the vertical axis and the months on the horizontal axis. By connecting the data points, we can see patterns and trends, such as variations in temperature during different seasons.
In addition, graphs allow us to make predictions and draw conclusions based on the data presented. By analyzing the shape and slope of a graph, we can determine the rate of change, identify maximum and minimum values, and make predictions about future outcomes.
What is the measure of ∠W, rounded to the nearest degree?
19°
32°
56°
71°
Answers
71°
Step-by-step explanation:This is an isosceles triangle because it has two sides with lengths, hence the angles opposite the equal sides are also equal, that is ∠U = ∠V.
So we can say that:
∠U = ∠V = α
∠W = β
Since the internal angles of a triangle add up to 180 degrees, then:
α + α + β = 180
2α + β = 180
β = 180 - 2α
Using the law of sine:
[tex]\frac{35}{sin\beta} =\frac{30}{sin\alpha} \\ \\ \frac{35}{sin(180 - 2\alpha)} =\frac{30}{sin\alpha} \\ \\ \\ From \ Properties: \\ \\ sin(180-2\alpha)=sin(180)cos2\alpha-sin2\alpha cos(180) \\ \\ = -sin2\alpha(-1)=sin2\alpha \\ \\ Also: \\ \\ sin2\alpha=2sin\alpha cos\alpha[/tex]
Therefore:
[tex]\frac{35}{2sin\alpha cos\alpha} =\frac{30}{sin\alpha} \\ \\ \therefore \frac{35}{60}=cos\alpha \\ \\ \alpha=cos^{-1}(\frac{7}{12})=54.31^{\circ}[/tex]
But we want to know ∠W = β, therefore:
[tex]\beta = 180 - 2\alpha \\ \\ \beta =180-2(54.31)=71.37^{\circ}[/tex]
And rounded to the nearest degree:
∠W = 71°
