Answer: a) 1.1962
after sig figs it’s 1.2
b) 0.4321
after sig figs it’s 0.43
Step-by-step explanation:
Calculation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 20 × 0.05 × 2 = 2
I = $ 2.00
The simple interest accumulated
on a principal of $ 20.00
at a rate of 5% per year
for 2 years is $ 2.00.
60.
let x be the number you're trying to solve.
(x/100)25 = 15
x/4 = 15
x = 15(4)
x = 60
Answer:
D 40,000nm
Step-by-step explanation: 1nm/10^-9m * 10^-6/1um = 10^3 nm/um
Therefore in 40 microns there are:
40um * 10^3 nm/um = 40 * 10^3 nm = 40,000 nm
The answer is C
I pretty sure
