Answer:
they are both scalene triangles

Explanation:
I added the given lengths of each triangle and then subtracted the sum from the perimeter

so for example;
18.2 + 13 = 31.2
50.7 - 31.2 = 19.5

18.2, 13, 19.5 are not equal

none of the sides of the triangle are equal therefore making the triangle a scalene triangle.

a scalene triangle is when no sides of a triangle are equal. an isosceles triangle is when two sides are equal and one is a different length. and an equilateral triangle is when all sides of the triangles are equal.

i used the same formula for the second problem. 11.2 + 12 = 23.3 then 31.2 - 23.2 = 8

11.2, 12, and 8 are not equal

Find the real solutions of the equations 7x to the fourth =56. Round your answers to two decimal places. Explain.

The equation 7x^4 = 56 can be rewritten as x^4 = 8. To find the real solutions of the equation, we take the fourth root of both sides:

What does a math equation mean?

Algebraically speaking, an equation is a statement that shows the equality of two mathematical expressions. For instance, the two equations 3x + 5 and 14, which are separated by the 'equal' sign, make up the equation 3x + 5 = 14.

x = ∛8 = 2.

So the real solutions of the equation are x = 2.

Note: since the fourth root of 8 is 2, we can check that the equation holds true. i.e 7*2^4 = 56

In circle O, FG=40 RS=37 OP=19 FG is perpendicular OP, and RS is perpendicular to OQ A. 27.2 B. 18.5 C. 19 D. 20.5

Answers

Answer: In order to solve this problem, you should use the Pythagorean theorem. Since FG is perpendicular to OP, and OP and OQ are radii of the same circle, then triangle OFG is a right triangle. Similarly, triangle ORS is also a right triangle. By using the Pythagorean theorem, you can find that:

OF = sqrt(OP^2 + FG^2) = sqrt(19^2 + 40^2) = sqrt(361 + 1600) = sqrt(1961)

and

OS = sqrt(OQ^2 + RS^2) = sqrt(19^2 + 37^2) = sqrt(361 + 1369) = sqrt(1740)

Therefore, the length of the segment connecting the feet of the altitudes is:

OF + OS = sqrt(1961) + sqrt(1740) = 27.2

So the answer is A. 27.2

there?

Please answer both.

Answers

The number of points Jim scored is 15 points.

The number of cars given the ratio of car to boat is 140 cars

How to solve algebraic expression?

Number of points Kevin has = xNumber of points Jim has = 8 + xTotal points = 22

Total points = Number of points Kevin has + Number of points Jim has

22 = x + (8 + x)

22 = x + 8 + x

22 = 2x + 8

22 - 8 = 2x

14 = 2x

divide both sides 2

x = 14/2

x = 7

Number of points Jim has = 8 + x

= 8 + 7

= 15 points

Part B:

Boat : car

2 : 5 = 56 : x

2/5 = 56/x

cross product

2 × x = 56 × 5

2x = 280

divide both sides by 2

x = 280/2

x = 140

Therefore, the number of points Jim scored is 15 points and the number of cars is 140

thermal expansion goes to zero at T approaches zero. By definition, the volume coefficient of thermal expansion is: beta

Answers

Yes, the coefficient of thermal expansion goes to zero at T approaches zero.The coefficient of thermal expansion is defined as the fractional change in volume per unit change in temperature.

The coefficient of thermal expansion is defined as the fractional change in volume per unit change in temperature. It is calculated by taking the derivative of volume with respect to temperature. Mathematically, it is expressed as β = (1/V) (dV/dT). As the temperature approaches zero, the change in volume (dV) will also approach zero, and thus the coefficient of thermal expansion (β) will approach zero as well.

The complete question : thermal expansion goes to zero at T approaches zero. By definition, the volume coefficient of thermal expansion is: beta = (1/V) (dV/dT). So, as T approaches zero, (dV/dT) approaches zero, and thus beta approaches zero.

Answers

The concept given is Sampling, which selects the group that you will actually collect data from in your research. The answer is option B, ​True; because it is often the case that the individuals who volunteer do not accurately represent the population.

Sampling is the selection of a subset of individualities from within a statistical population to estimate the characteristics of the whole population. Statisticians essay to collect samples that are representative of the population in question.

Frequently, voluntary response samples oversample people who have strong opinions and under-sample people who do not watch important about the content of the check. Therefore consequences from a voluntary response sample aren't as secure as conclusions grounded on an arbitrary sample of the entire population under consideration.

Volunteer slice doesn't induce a representative sample, so, thus, would not be the favored choice of experimenters who were keen to be suitable to generalize their data to the whole population.

A point rotating -90° about the origin will have its x-coordinate become its y-coordinate and its y-coordinate become its negative x-coordinate.

What is the area of triangle if sides are 9cm 12cm and 15cm *?

Answers

The area of the triangle is 54 square cm.

To find the area of a triangle, we can use Heron's Formula, which states that the area of a triangle is equal to the √ (s * (s-a) * (s-b) * (s-c)), where s is the semi-perimeter of the triangle and a, b, and c are the sides of the triangle.

Step 1: Find the semi-perimeter of the triangle. s = (9 + 12 + 15) / 2 = 21 / 2 = 10.5

Step 2: Substitute the semi-perimeter and the sides of the triangle into Heron's Formula.

Area =  √(10.5 × (10.5 - 9) × (10.5 - 12) × (10.5 - 15))

Step 3: Simplify the equation.

Area = √ (10.5 × 1.5 × -1.5 × -4.5)

Step 4: Perform the square root.

Area = √ -94.5 = 54 square cm.

Area = 54 square cm.

Answers

The 100th prime number is 541.

Therefore the answer is 541.

Prime numbers are numbers that are divisible by only 1 and themselves. They are considered to be the "building blocks" of the natural numbers, and are important in number theory and other branches of mathematics.

Prime numbers are fundamental for number theory and have a lot of applications in cryptography, coding theory, and other areas of mathematics.

The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29. The primes continue indefinitely, with no repeating pattern or predictable distribution. Finding the nth prime number is not an easy task, it requires knowledge of number theory and a lot of computational power.

In general, the nth prime number grows faster than any polynomial in n. The 100th prime number is larger than the 100th Fibonacci number (which is about 354) and smaller than the 100th triangular number (which is about 5050).
