A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees
Area of a triangle = 1/2 x base x height
the perimeter of a triangle = sum of the side lengths
A right angled triangle has a 90 degree angle and two other sides that sum up to 90 degrees. this makes the sum of angles 180 degrees

A new shopping mall is considering setting up an information desk manned by one employee. Based upon information obtained from similar information desks, it is believed that people will arrive at the desk at a rate of 20 per hour. It takes an average of 2 minutes to answer a question. It is assumed that the arrivals follow a Poisson distribution and answer times are exponentially distributed. Assume that the information desk employee in Problem 1 earns $10 per hour. The cost of waiting time, in terms of customer unhappiness with the mall, is $12 per hour of time spent waiting in line. Find the total expected costs over an 8-hour day
Answers
Answer:
tsc = 8*1*10 = $80
twc = 8*20*0.0667*12 = $128.06
tc = 80 + 128.06 = $208.06
Step-by-step explanation:
To find the total expected costs for an 8 hour period, first you must find the total service costs (tsc) and the total waiting costs (twc) as the two costs are what make up the total cost (tc).
Total service cost = (the number of channels)(cost per channel)
tsc = m*Cs
There is only 1 employee so the number of channels is 1.
The cost for this channel is $10 per hour, so 10 * 8 hours in the day.
Total waiting cost = (total time spent waiting by all arrivals)(cost of waiting)
twc = (number of arrivals)(average wait per arrival) Cw
The number arrivals is at the rate of 20 per hour.
The average wait per arrival was found as Wq previously.
Wq = 20/(30*(30-20)) = 0.0667 hours
The cost of waiting (Cw) is the $12 per hour multiplied by the 8 hour day.
Total Expected Cost for an 8 hour day is the sum of the total service cost plus the total waiting cost.

[tex]in \: this \: shape \: you \: have \: two \: pieces \: one \: square \: ad \: half \: of \: circle \\ area \: of \: circle = 12 \times 12 = 144 \\ area \: of \: hafl \: of \: circle = 12 \times 12 \times 0.25 \times 3.14 = 113.04 \\ whole \: area = 144 + 113.04 = 257.04[/tex]
Answer: E. 200.5 ft
so first you’d find the area of the square which is 12 x 12 = 144 (area = length x width)
next, find the radius of the semi circle which is 12 divided by 2 (because we used the measurements from the square and the diameter is 12 and radius is half of diameter)
pretend your solving for a full circle and then divide it by 2 to get the answer for the semi circle since a semi circle is half of a circle (formula for circle A = pi r^2)
area of circle = 113.04 divided by 2 to get semi circle = 56.5
then add both areas together
56.52 + 144 = 200.5

* By definition, the sum of the interior angles of a triangle is 180 degrees.
* Keeping this in mind, you have:
As you can see, the sum of the other two angles must be 108 degrees, then, let's add the angles given in each option:
A) 9°+9°=18
B) 26°+46°=72°
C)53°+55°=108°
D)72°+108°=180°
*Therefore, the answer is option C.
5.is "B"
A triangle is called a right triangle when one of it's angles measures 90°.
We have been given the second angle as 14°.
The angles in a triangle add up to 180°.
∴ letting the third angle to be X;
X + 14° + 90° = 180°
X + 104° = 180°
X = 180° - 104°
= 76°
7. the answer is "B"
A = 41 * 14 / 2
A = 574 / 2
A = 287 cm²
So, the area of the trapezoid is 287 cm².
9. is "B"
Area = base x height
Or 356.25=14.25 x Height
Dividing both sides by 14.25
Height =25inches
.Height of the parallelogram is 25 inches. the answer is "B"
10.is "B"

Write 3.5 times 4 using words ?
Answers
Answer:
three point five multiplied by four
Step-by-step explanation:
To write 3.5 times 4 using words, we can say:
"Three point five times four."
We know that, "Three point five" refers to the number 3.5, which is a decimal number.
In words, we read the decimal point as "point."
"Times" indicates multiplication.
When we say "times" between two numbers, it means we are multiplying them together.
"Four" represents the number 4, which is the second number in the multiplication.
so, we have, all together, "Three point five times four" means we are multiplying the decimal number 3.5 by the whole number 4.
The result of this multiplication is 14 because 3.5 times 4 equals 14.
