Answer:
The geometric sequence is 27,9,3,1,1/3, 1/9,1/27 ....
Step-by-step explanation:
We have given the 5th term a5 = 1/3
Constant ratio r= 1/3
a5 = a 1 * r^4
1/3= a1 * (1/3)^4
1/3 = a1* 1/81
a1= 1/3 : 1/81
We can solve it as:
a1 = 1/3 * 81
a1= 27
Thus the geometric sequence is 27,9,3,1,1/3, 1/9,1/27 ....
Answer: 6 inches
Step-by-step explanation:
15 divided by 2.5 is 6 inches.
Answer:
see below
Step-by-step explanation:
As with many multiple-choice questions, the appropriate choices can often be determined with a simple test. Here, you only need to look at the values of the constants. (Those are ringed in blue.)
Answer:
I'm kind of confused what the question is asking. If they are asking for an expression to represent JL then the answer is 14x -32. If they want to know the distance between J and L then the answer is 66
Step-by-step explanation:
First I set the 2 equations equal to each other (5x-2 = 9x -30) and solved this to get x =7. (ANSWER ONE)
Next I plugged 7 into one of the equations (in this case either one will work bc JK and KL are the same distance. so I plugged 7 into the first one ( 5(7) -2 ) and I got 33. This means the distance of JK (and KL since they are equal) is 33.
Next I multiplied 33 by 2 since JL is JK and KL combined ( JK and KL are both 33 and therefore adding them together (multiplying 33×2) will give you the length of JL) and I got 66 (ANSWER 2)
Sorry if this is super confusing
Answer:
40 days saw either rain or high winds
Step-by-step explanation:
We solve this question using Venn sets.
I am going to say that:
Set A: Rain
Set B: High winds.
18 days saw rain
This means that
29 days saw high winds
This means that
7 days saw both rain and high winds.
This means that
How many days saw either rain or high winds?
This is
Sp
40 days saw either rain or high winds
