She paid $30 bucks total.
Answer:
see below
Step-by-step explanation:
The ratio of terms that are two terms apart (s4 and s6) is the square of the common ratio:
s6/s4 = r^2
r = √(8/18)
r = 2/3 . . . . . matches choices A and C
__
Using the formula for the general term, we now know enough to find the first term:
sn = s1·r^(n-1)
s4 = s1·(2/3)^(4-1)
Using s4 = 18 and multiplying by (2/3)^-3, we get ...
18·(2/3)^-3 = s1 = 18·27/8
s1 = 243/4 . . . . . matches choice A
Answer:
Step-by-step explanation:
Let the invested amount is x
- Interest rate is r = 5% simple = 0.05 times
- Time is t = 3 years
- Interest amount I = AED. 450
<u>Using the interest formula and solving for x:</u>
- P*r*t = I
- x*0.05*3 = 450
- 0.15x = 450
- x = 450/0.15
- x = 3000
The amount invested is AED 3000
Answer:
The equation means x times 4 x 8.
Step-by-step explanation:
a dot means multiplication and in PEMDAS things in parenthesis should be done first so that is the simplified version of the equation.
