Answer:
0.7
Step-by-step explanation:
7 x 0.10
=> 7 x 0.1
=> 7 x 1/10
=> 7/10
=> 0.7
This is a geometric sequence of the form:
a(n)=(x+3)(-2x)^(n-1) because each term is -2x times the previous term...so
a(8)=(x+3)(-128x^7)
a(8)=-128x^8-384x^7
Answer:
screw this question
Step-by-step explanation:
To change from 15% to 25% he needs to add 10%.
If the solution is 50ml then he needs to add 10% which is 5ml... But if he adds 5 ml then the solution will be 55ml total, so that doesn't make sense. He has to take some of the solution that's not acid before adding the 5ml...
Answer:
$911.02
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 1.25%/100 = 0.0125 per year,
then, solving our equation
I = 845 × 0.0125 × 6.25 = 66.015625
I = $ 66.02
The simple interest accumulated
on a principal of $ 845.00
at a rate of 1.25% per year
for 6.25 years is $ 66.02.
