Answer: To solve such problems we need to know about Trigonometry.
Trigonometric functions
where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.
The value of x is 5√3.
Explanation: Given to us,
the base for the triangle, AB = 5 units,
Hypotenuse for the triangle, BC = 10 units,
∠B = 60°,
Solution
The question can be solved in two ways,
1. Using the Pythagoras theorem,
According to Pythagoras theorem,
substituting the values,
2. using the trigonometric function for ∠B,
for ∠B in ΔABC,
substituting the values,
we know that value of tan(60°) is √3,
Hence, the value of x is 5√3.
Element m reacts with oxygen to form an oxide with the formula mo. When mo is dissolved in water, the resulting solution is basic. Element m could be ________
Answer:
Ca (Calcium)
Explanation:
Calcium is a positive ion with a charge of 2+. The metal is also an alkali earth metal since the oxide MO is basic when dissolved in water.
In light of the preceding circumstances;
The metal is not arsenic since arsenic is a metalloid with the oxides As2O3 and As3O5, which are amphoteric (reactive as both, a base and/or acid) and acidic in nature, respectively.
Because it is a metalloid, the metal is not germanium, and even though germanium oxide has the formula GeO2, it is amphoteric.
Because chlorine is a non-metal, the metal is not chlorine.
Because calcium oxide has the formula CaO and calcium is an alkaline earth metal, the metal is unmistakably calcium.
Because selenium is anon-meal and its oxide has the formula Se02 and is acidic, the metal is not selenium.
Use a distributive property to rewrite the expression. then simplify the expression. a(b − 8)
Answer:
[tex]ab-8a[/tex]
Explanation:
Given the following question:
[tex]a(b-8)[/tex]
To apply the distributive property to an expression we have to multiply all terms within the paratheses by the terms outside the paratheses.
[tex]a(b-8)[/tex]
[tex]a\timesb=ab[/tex]
[tex]8\times a=8a[/tex]
[tex]ab-8a[/tex]
Your answer is "ab - 8a."
Hope this helps.
Answer:
ab-8a the answer simplified. (multiple using distributive property)
Now, imagine that port chester decides to crack down on motorists who park illegally by increasing the number of officers issuing parking tickets (thus, raising the probability of a ticket). If the cost of a ticket is $100, and the opportunity cost for the average driver of searching for parking is $25, which of the following probabilities would make the average person stop parking illegally? assume that people will not park illegally if the expected value of doing so is negative. Check all that apply
Assuming that people will not park illegally if the expected value of doing so is negative, the probability that a person could stop illegally parking would be 26% and 31%.
How to find the expected value?It is necessary to carry out the calculation, which is given by the following formula:
Expected value = P(x) × nApplying the values in the formula, we find the values:
= -(100 x 26%) + 25 = -(100 x 31%) + 25= -1$ = -$6Therefore, the 26% and 31% probabilities are the negative probabilities.
This is an incomplete question, and the other alternatives are:
A. 26%
B. 31%
C. 23%

You push an object initially at rest across a frictionless floor
t = t₀ / 2
Explanation:
In this exercise we must use Newton's second law
F = m a
a = F / m
now we can use kinematics
as in object part of rest (v₀ = 0)
v =a t₀
t₀ = v / a
these results are with the first experiment
now repeat the experiment, but F = 2F₀
a = 2F₀ / m = 2 a₀
v = 2 a₀ t
t = v / 2a₀
t = t₀ / 2

The reaction 2mg(s)+o2(g)→2mgo(s) is highly spontaneous. A classmate calculates the entropy change for this reaction and obtains a large negative value for δs∘
Since there is a decrease in entropy owing to the solid product hence a large negative change in entropy is obtained.
What is entropy?The term entropy is the degree of disorder of a system. This question is incomplete but I will try to approach it in a general way. The equation of the reaction is; 2Mg(s) + O2(g)→2MgO(s).
We can see that in the reaction, the product of the process is a solid. Since a solid is rigidly arranged hence the entropy is largely decreased and a large negative change in entropy is obtained.

When 5 grams of kcl are dissolved in 50. Grams of water at 25°c, the resulting mixture can be described as
Answer:
3. Homogenous and unsaturated
Explanation:
Since your given information mentions 50 grams of solvent and 5 grams of solute, you must double each amount because "
Table G Solubility Curves" in the Regents Chemistry Reference Table notates curves based off of 100 g samples of water. Therefore, you must look for how soluble 10 grams of KCl is in 100 grams of water at 25 degrees Celsius.
As the picture shows, 10 grams of KCl is well below the curve for saturation, meaning that the solution is undersaturated.
As for the second part of the answer, we can tell that the solution is homogenous (of uniform composition) because there is no possibility of the salt, KCl, falling out of solution and making the mixture heterogenous (of mixed composition).
Putting all of those ideas together, we can tell that the answer to this question is:
3. Homogenous and unsaturated
