Hello!

Because the three sides of the triangle have equal lengths, we can confirm that the image above represents an equilateral triangle. An equilateral triangle is a triangle whose three sides are the same length and whose three angles are the same measure. We know that the three angles of a triangle must always add to a sum of 180 degrees. With this knowledge, we can create the following equation (let “x” represent the measure of each angle):

x + x + x = 180

Combine like terms:

3x = 180

Divide both sides fo the equation by 3:

x = 60

We have now proven that all three angles of ΔABC have a measure of 60 degrees. Therfore, ∠C must have a measure of 60 degrees.

I hope this helps!

Among fatal plane crashes that occurred during the past 55 years, 415 were due to pilot error, 96 were due to other human err

azamat

Answer:

Relative frequency:

$\text{Pilot error}=415/1370=0.30\\\\\text{Other human error}=96/1370=0.07\\\\\text{Weather}=169/1370=0.12\\\\\text{Mechanical problems}=622/1370=0.45\\\\\text{Sabotage}=68/1370=0.05\\\\$

The most serious threat to aviation safety is, according to this data, "mechanical failures". It can be improved by more rigorous inspection and better maintenance policies and execution.

Step-by-step explanation:

We have the data for fatal plane crashes. The sum of plane crashes is

We can calculate the relative frequency as:

$\text{Pilot error}=415/1370=0.30\\\\\text{Other human error}=96/1370=0.07\\\\\text{Weather}=169/1370=0.12\\\\\text{Mechanical problems}=622/1370=0.45\\\\\text{Sabotage}=68/1370=0.05\\\\$

We can see that the most frequent cause is "mechanical problems", with a relative frequency of 0.45.

Linda took a math test and got 68 correct answers and 12 incorrect answers. What is the percentage of incorrect answers

iogann1982 [59]

Answer:

Approximately $17.6$ percent

Step-by-step explanation:

To find a percentage, take the part, divide it by the whole, and multiply that quotient by 100. As an algebraic expression, that would be $\frac{part}{whole}*100$ .

In this case, the part is $12$ and the whole is $68$ . Therefore, our answer is $\frac{12}{68}*100\approx17.6$ percent. Hope this helps!

a restaurant can seat 100 people . it has booths that seat 4 people and tables that seat 6 people.so far , 5 of the booths are f

Natasha2012 [34]

Is this the whole question? If so, this how I found my answer(I do not know if this is the answer 100% and I won't and can't take credit for the answer being incorrect. It is your choice to go with my answer, thank you.):

A restaurant can seat 100 people. Okay, the capacity is 100. Got it. It has booths that seat 4 people. Okay! So I am going to represent B"Booths" as "B". A variable. B = 4. Okay, let's continue. And, it has tables that seat 6 people. I will represent "Tables" as T. So, T = 6!

Alllrighty then, let's get to the nit and grit..

B = 4 T = 6

In the last sentence, it says, 5 of the booths are full, what expression matches the situation? Well, it's ONLY asking for the expression, so that's all we'll give.

We don't need the "table" variable because it's asking about the booths so, bye bye tables. B = 4, and 5 of them are full. We would have to do B(5) or B * 5. B equals 4 so 4 * 5 which equals 20. The expressions we could use are:

B(5) = 20
or
4 * 5 = 20
or
20 = 4 * 5 = B(5)

I hope this answer helps you out! Bye! :)
