What you need to do is make each fraction into a decimal and then put them in order from least to greatest.
7/12=0.583
1/8= 0.125
5/16= 0.3125
5/6= 0.83
The order for this is 0.3125, 0.125, 0.583, and 0.83. So the answer is last option
Answer:
D. 108.4 mm
Step-by-step explanation:
Since the larger triangle is 4 times of the small triangle...
27.1 x 4 = 108.4 mm
a) The students who are members of both sets can be described by
... a ∩ b
b) The students who are members of a but not b can be described by
... a ∩ b'
c) The students who are members of one or both sets can be described by
... a ∪ b
d) The students who are not in one set or not in the other set can be described by
... a' ∪ b' . . . . = (a ∩ b)'
Answer:
Step-by-step explanation:
First I want to set up some variables.
S = sum
n = final term
ax = xth term, so a1 is the first term and an is the last one
d = common difference.
There are two formulas to find the sum, if you don't get how they were gotten I'd be happy to explain.
S = (n/2)(a1+an) = (n/2)(2a1+(n-1)d)
So, to find n we use the first one.
S = (n/2)(a1+an)
123 = (n/2)(8+33)
123 = (n/2)41
3 = n/2
6 = n
Now we can find d with the other one
S = (n/2)(2a1+(n-1)d)
123 = (6/2)(2*8+(6-1)d)
123 = 3(16+5d)
41 = 16+5d
25 = 5d
5 = d
so there are six terms and the common difference is 5.
The correct answer is b and c
