Answer:
B
Step-by-step explanation:
We can use the law of cosinse:
= 
− 2ab cos(C)
Suppose the two sides are a and b, and the angle betweent them is C.
= 
− 2*3*4 cos(60)
We can simplify this to get =25-12=13
c=
Answer choice B

Answer:
There are 96 large tents and 60 small tents
Step-by-step explanation:
Here, we want to calculate the number of tents of each sizes there
Let the number of 6-boys tent be s and the number of 4-boys tent be f
6s + 4f = 816 ••••••(i)
Ratio of large to small ( ratio of s to f)
8:5 = s/f
8/5 = s/f
8f = 5s
f = 5s/8 ••••(ii)
Substitute ii into i
6s + 4(5s/8) = 816
6s + 5s/2 = 816
Multiply through by 2
12s + 5s = 1,632
17s = 1632
s = 1632/17
s = 96
f = 5s/8
f = (5 * 96)/8 = 60
Answer:
If you see the top and bottom of the figures are getting smaller by two, so for A its getting smaller by two, and for B it will just be a solid set of four lines
Step-by-step explanation: make sure you put it in you own words
(-79.54) / (-9.7) = <span>8.2
Steps:
