Select the correct answer. what is the value of x in the triangle? an isosceles right triangle with two legs of length 10 and hypotenuse of length x a. b. c. d. e.
Answers
Answer:
[tex]10\sqrt{2}[/tex]
Explanation:
There is a diagram attached which models the situation.
Since the given triangle is right, we are able to use the Pythagorean Theorem, which states when a and b are the legs of a right triangle and c is the hypotenuse:
[tex]a^{2} + b^{2} = c^{2}[/tex]
We can plug in the given values. Since both legs have a value of ten, we can say:
[tex]10^{2} + 10^{2} = c^{2}\\100 + 100 = c^{2}\\200 = c^{2}\\c = \sqrt{200}[/tex]
We can split 200 into 100 x 2, and [tex]\sqrt{100 }[/tex] is 10, so [tex]\sqrt{200} = 10\sqrt{2}[/tex]
Another way to do this use the given of the triangle being isosceles right. In an isosceles right triangle, the hypotenuse is always [tex]\sqrt{2}[/tex] times the base. So a triangle with legs 10 would have a hypotenuse of [tex]10\sqrt{2}[/tex].

Suppose the length of an oarfish is normally distributed with a mean of 6.5 m and a standard deviation of 1.5 m. which group describes 16% of the oarfish population? select each correct answer.
Answers
Answer:
Explanation:
oarfish that are shorter than 5 m
Let x be the random variable representing the length of an oarfish. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = standard deviation
The given probability value is 16% = 0.16. From the normal distribution table, the z score corresponding to the probability value is - 0.99
This indicates that the sample mean is lower than the population mean
Therefore,
- 0.99 = (x - 6.5)/1.5
- 0.99 × 1.5 = x - 6.5
- 1.5 = x - 6.5
x = - 1.5 + 6.5
x = 5m
The correct answer is
oarfish that are shorter than 5 m

Answer 1) Decomposing (Electrolysis)
Explanation :
Hydrogen can be created by decomposing water. Electrolysis which is a method of passing electricity from the water and obtaining the products as hydrogen and oxygen is done by decomposition of water. The water molecule is broken down into its constituents.
Answer 2) Solar energy
Explanation :
If the activation energy is reduced, hydrogen can be produced with a renewable energy source. This renewable energy source is Solar energy.
Solar energy from the sun can be used to lower the energy of activation during the decomposition of water. Solar energy is a renewable energy source as it comes from the sun and is replenish-able unlike fuels which cannot be replenished. The solar energy can be collected and utilized for production of hydrogen.

The cross-sectional areas of a triangular prism and a right cylinder are congruent. the triangular prism has a height of 10 units, and the right cylinder has a height of 7 units. which conclusion can be made from the given information? the volume of the prism is half the volume of the cylinder. the volume of the prism is not equal to the volume of the cylinder. the volume of the prism is twice the volume of the cylinder. the volume of the prism is equal to the volume of the cylinder.
Answers
The volume of the right-angle prism and the right-cylinder shapes is not equal. Thus, option A is correct.
What is Volume?Volume is given as the scalar quantity that can measure the space occupied by a three-dimensional object.
The volume of the prism is given as:
Volume of prism = Area * Height
The volume of right cylinder is given as:
Volume of cylinder = Area * Height
The given two shapes are congruent to each other, thereby the area of the base of the prism and cylinder are equal. Substituting the height of both the shapes:
The volume of Prism = 10 Area
Volume of right cylinder = 7 Area
The ratio of the volume of both shapes gives:
Volume of Prism/ Volume of Cylinder = 10 Area/ 7 Area
Volume of Prism/ Volume of Cylinder = 1.42
Volume of Prism = 1.42 Volume of Cylinder
Thus, the volume of Prism is 1.42 times more than the volume of a cylinder. Hence, the volume of both shapes is not equal. Thus, option A is correct.

Of the 318 sophomores, 140 are taking algebra 2 and 102 are taking chemistry. of those that are taking chemistry, 76 are not taking algebra 2. if a sophomore is chosen at random, find the probability that they are taking algebra 2, if it is known that they take chemistry.
Answers
The probability that the sophomores are taking algebra 2 is equal to 0.63.
How to find the probability?In order to determine the probability that the sophomores are taking algebra 2, we would calculate the number of sophomores that takes algebra 2 but not chemistry and those that do not take chemistry.
For algebra 2 but not chemistry, we have:
Algebra 2 but not chemistry = 140 - 76
Algebra 2 but not chemistry = 64.
For those not taking chemistry, we have:
Not taking chemistry = 318 - 102
Not taking chemistry = 216.
Now, we can find the probability that the sophomores are taking algebra 2:
P(A) = 64/102
P(A) = 32/51
P(A) = 0.63.

A container with a fixed volume filled with hydrogen gas
Answers
Based on the calculations, the new temperature of this hydrogen gas at a fixed volume is equal to 258.72°C.
How to determine the new temperature?In order to calculate the new temperature of this hydrogen gas at a fixed volume, we would apply Gay Lussac's law.
Mathematically, Gay Lussac's law is given by this formula;
P α T
P = kT
Where:
P is the pressure.T is the temperature.k is the constant of proportionality.Given the following data:
Initial temperature = -104°C to K = 273 - 104 = 169 K.Final pressure = 71.8 kPa.Initial pressure = 225.9 kPa.Substituting the given parameters into the formula, we have;
[tex]\frac{P_1}{T_1} =\frac{P_2}{T_2} \\\\\frac{71.8}{169} =\frac{225.9}{T_2} \\\\71.8T_2 =38177.1\\\\T_2 = 38177.1/71.8[/tex]
T₂ = 372.5/0.96
New temperature = 531.72 K.
