Step-by-step explanation:
Answer:
x=21.35764429=21.4
Step-by-step explanation:
Take SOHCAHTOA
in this problem you're going to use SOH, which is sine= opposite/hypotenuse
sin31=11/x
Multiply by x as a way to isolate it
x(sin31)=11
divide my sin31 to isolate x
x=11/sin31
x=21.35764429
Answer:
the missing number is 84
Step-by-step explanation:
Let the missing number be represented by N. Then we have ...
7*3 = N*3/(4*3)
Canceling common factors on the right, we have ...
7*3 = N/4
Multiplying by 4 gives ...
4*7*3 = N = 84
The missing number is 84.
There are two ways to solve this problem. First, you can use the derived formula for geometric sequence which can be used to find any nth term of the sequence. Or, we can use the second easier way. Since we are given with the 700th term, and the asked is the 699th term, then that means,
(699th term)*(Common Ratio) = 700th term
699th term = 700th term/Common Ratio = 20/0.25 = <em>80</em>
