name the following triangle according to its angles and sides: 120 degrees, 35 degrees, 25 degrees
Final answer:
The triangle with angles of 120 degrees, 35 degrees, and 25 degrees is classified as an obtuse scalene triangle because it has one angle greater than 90 degrees and all angles of different measures.
Explanation:
To classify the triangle with angles of 120 degrees, 35 degrees, and 25 degrees, we first confirm that the sum of its angles is 180 degrees, which is true for any plane triangle. Given this sum, we can classify the triangle based on its angles and sides.
A triangle with one angle greater than 90 degrees is called an obtuse triangle, as it has an obtuse angle (greater than 90 degrees). Since this triangle has a 120-degree angle, it fits that definition. Furthermore, because all the angles are different, we can classify it as a scalene triangle, meaning all sides have different lengths. Therefore, the correct classification for this triangle is an obtuse scalene triangle.
A circular plate has circumference 34.5 inches. What is the area of this plate? Use 3.14 for pi.
To find the area of the plate, we first calculate the radius using the given circumference and then plug this into our formula to find the area. The calculated area of the plate is approximately 94.52 square inches.
Explanation:The student is asking for the area of a circular plate with a given circumference, using 3.14 for pi. The formula to calculate the area of a circle is A = πr². However, we only have the circumference, which allows us to find the radius using the formula C = 2πr, or rearranged to solve for r, r = C / (2π). Plugging in the given circumference of 34.5 inches, we find the radius to be 34.5 / (2 * 3.14) = 5.49 inches. Now, we can find the area by substitifying this value back into our area formula, A = πr², yielding A = (3.14) * (5.49²) ≈ 94.52 square inches.

To find the area of the circular plate having its circumference as 34.5 inches, we firstly calculate its radius using the formula r = Circumference/(2π) which gives approximately 5.49 inches. We then substitute the radius value in the formula for area of a circle (Area = πr²), yielding an area of approximately 94.52 square inches.
Explanation:In mathematics, the circumference of a circle is related to its radius through the formula: Circumference = 2πr.
Given that the circumference of the plate is 34.5 inches, and we use 3.14 for π, we first work out the radius by rearranging the formula like so: r = Circumference / (2π).
Substitute the given values: r = 34.5 inches / (2*3.14)
Do the calculation: r approximately equals 5.49 inches.
Next, use the formula for the area of the circle which is: Area = πr².
Substitute r: Area = 3.14 * (5.49 inches)²
Calculate: Area is approximately 94.52 square inches.

Find an equation for the inverse of the relation y=6x-3. Show how you found the inverse equation.
The inverse of the relation y=6x-3 is y = (x + 3) / 6.
To find an equation for the inverse of the relation y=6x-3, we need to follow a series of steps which involves swapping the variables, and then solving for the new y.
Start with the initial equation: y = 6x - 3.
Swap the variables x and y: x = 6y - 3.
Solve for y to find the inverse relation: Add 3 to both sides to get x + 3 = 6y, then divide both sides by 6 to isolate y, resulting in y = (x + 3) / 6.
Grace sureyed 60 random students in her school.Of these 14 said they enjoy watching Dancing with the star.A total of 570 students in the school. How many these are expected to enjoy dancing with the Stars?
Using the proportion of students who enjoy watching Dancing with the Stars from Grace's survey, we can estimate that approximately 133 students at her school are expected to enjoy the show.
Grace surveyed 60 random students at her school and found that 14 enjoy watching Dancing with the Stars. With a total of 570 students in the school, we can establish a proportion to estimate how many students school-wide might enjoy the show. We do this by setting up a ratio of students who enjoy the show to the total number of students surveyed and then use that ratio to estimate the number for the entire school population.
To calculate, we take the ratio from the survey (14/60) and apply it to the total student body (570) like so:
Determine the ratio of students who enjoy the show from the survey: 14 out of 60.Find what proportion that ratio represents: 14/60 = 0.2333 (rounded to four decimal places).Apply this proportion to the entire student population: 0.2333 * 570 = 133.01, which we round to 133 students expected to enjoy Dancing with the Stars.Therefore, approximately 133 students in Grace's school are expected to enjoy watching Dancing with the Stars.

Kurt bought a bike for $149.95. Eric bought a bike that had been $169.50 but was marked 1/5 off. How much less did Eric’s bike cost than Kurt’s?
After calculating the discount and subtracting it from the original price, Eric's bike cost $135.60, which is $14.35 less than Kurt's bike that cost $149.95.
To determine how much less Eric paid for his bike compared to Kurt's bike, we need to calculate the discount Eric received and subtract it from the original price of his bike. Then, we'll compare it to the price Kurt paid for his bike.
First, we calculate Eric's discount by multiplying the original price of the bike, $169.50, by 1/5 (which represents the 20% discount):
$169.50 times 15= $33.90.
Now, subtract this discount from the original price to find out how much Eric paid for the bike:
$169.50 - $33.90 = $135.60.
Finally, to find out how much less Eric's bike cost than Kurt's, we subtract the price Eric paid from the price Kurt paid:
$149.95 - $135.60 = $14.35.
Eric's bike cost $14.35 less than Kurt's.
