Answer:
-9 1/3
Step-by-step explanation:
Step 1. turn the the second fraction upside down which it then becomes a reciprocal
Step 2. then multiply the first fraction by that same reciprocal that you found
Step 3 simplify the fraction
Compound interest formula:
A = P(1+r/n)^nt
A ifs total amount
P = principal
r = interest rate
t = time
n = compound time
A = 2000(1+0.03/1)^4*1
A = $2,251.02
Answer:
5⁶⁴ = 152587890625⁴ bacteria's at 7 hours
Step-by-step explanation:
Simple..
it means the bacteria is increasing exponentially.
This is a geometric progression.
at 0 hrs = 0 bacteria
at 1 hr = 5 bacteria
at 2hr = 25 " = 5²
at 3hrs = 25 x 25 = 5² x 5² = 5⁴
at 4hrs = (25x25) x (25x25) = 5⁴x5⁴ = 5⁸
at 5hrs = (5⁸)² = 5⁸ˣ² = 5¹⁶
at 6 hrs = (5¹⁶)² = 5¹⁶ˣ²= 5³²
at 7 hrs = (5³²)² = 5³²ˣ² = 5⁶⁴
5⁶⁴ = 152587890625⁴
7(x+y) because their both factors of 7
