Answer: B) 0
Step-by-step explanation:
1. When you add complex numbers you must add the whole parts and then the imaginary parts.
2. One of the properties of complex numbers is called "Additive identity" which is represented by:
3. Then, for the complex number 
, you have:
4. Therefore, the answer is the option B.
Speed = distance / time
30 = d / 2.5
30 * 2.5 = d
75 = d
40 = d / 1.875
40 * 1.875 = d
75 = d
50 = d / 1.5
50 * 1.5 = d
75 = d
60 = d / 1.25
60 * 1.25 = d
75 = d
24 = 75 / time
time = 75/24
time = 3.125 hours
Answer:
Step-by-step explanation:
given that tonya charges 20$ monthly fee and 3$ per mile of her dog-walking service.
and beth does not charge any monthly fee but charges 5$ per mile of the dog walked in.
let x be the number of miles dog has walked in a month.
the amount tonya will charge on x miles = fixed monthly fee + number of miles * charge per mile = 20+3x
and the amount beth will charge on x miles = 0+ 5*x = 5x.
we are asked to find the x-value for which beth chargeable amount = tonya chargeable amount
that is 5x = 20+3x
5x-2x = 20
2x=20
x=
hence number of miles for which tonya and beth will charge the same amount is 10.
Answer:
The answer to your question is Superficial area = 144 + 36√3
Step-by-step explanation:
Process
1.- Calculate the area of the base
Area = base x height / 2
-Calculate the height using the Pythagorean theorem
h² = 12² - 6²
h² = 144 - 36
h² = 108
h = √108
108 2
54 2
27 3
9 3
3 3
1
h = 6√3
Area = 12 x 6√3/2
Area = 36√3 u²
2.- Calculate the area of the superficial 3 triangles
Area = base x height / 2
-Calculate the height using the Pythagorean theorem
h² = 10² - 6²
h² = 100 - 36
h² = 64
h = 8
Area = 12 x 8/2
Area = 48 u²
Total area = 3(48) + 36√3
= 144 + 36√3
47 = 50 - 3 or:
47 = Mean - 1 Standard deviation
For normal distribution it means that 4 bags represent 16 % of all samples.
4 bags ------ 16%
x bags ------ 100 %
---------------------------
4 * 100 = x * 16
16 x = 400
x = 400 : 16
x = 25
Answer: 25 bags were probably taken as samples.
