Answer:
53/5 = 10 3/5
Step-by-step explanation:
convert both to fraction
7x5 + 1 = 36
3x5 + 2 = 17
36 + 17 = 53
actually you could have just added
7 + 3 = 10
1 + 2 = 3 for the fraction
A. Divide number of people in the shop by total people walking by:
66/125 = 0.528 = 0.53
B. Divide people who bought something by total people walking by:
21/125 = 0.168 = 0.17
d. 66 -21 = 45 people don’t buy anything.
45/66 = 0.68
Answer: x=2
Isolate the variable by dividing each side by the factors that don't contain variables.
Answer:
V = (s^3)/6 (Answer B )
Step-by-step explanation:
If the length of a side of the base is s, then the height of the pyramid is half that, or s/2.
The volume of a pyramid with a square base and base side length S and height H is V = (1/3)(S^2)(H).
In this case, the formula is V = (1/3)(s^2)(s/2), or V = (s^3)/6 (Answer B)
Answer:
Step-by-step explanation:
you are given the law of sines, in the question, so i'm guessing you don't get "law of sines" ???
some times I think people might just be lazy and they don't try, but I can understand if you really don't get "law of sines' b/c it is kinda abstract.
Any way here is how you solve this problem and please ask if you don't understand about something I do to solve this. Ask about it if you don't get it. :)
Sin(45) / c = Sin(45) / 3
now algebraically solve for c
3* Sin(45) / Sin(45) = c
if you're thinking the answer is 3 you're right.
indecently , if you didn't notice, this is an isosceles triangle and they do have the same length legs. so you know that x = 3 right away from that, but, it's good to understand Law of Sines as well. :)
