82+ 90+78+100 = 350
Tim wants to have a test average of 90% on all of his 6 tests then
90 x 6 = 540

540 - 350 = 190

 the average of Tim’s next two tests = 190 / 2 = 95

Anni [7]

The loan proceeds will be given as follows:
A=P(1+r/100)^n
Plugging the values we obtain
n=4 months=
A=1000(1+12/3*100)^1
A=$1040
hence the proceeds will be:
1040-1000=$40

1.08t can be written as (1.081/12)12t to give the approximate equivalent monthly interest rate based on an annual rate of 8%. Us

kobusy [5.1K]

Because t is given in years and 1.08 = 1 + 0.08, the annual percent increase
is 8%.
To find the monthly percent increase that gives an 8% annual increase,
use the fact that
t = $\frac{1}{12} * 12 t$ 
and the properties of exponents to rewrite the
model in a form that reveals the monthly growth rate.

$1.08^{t} 
= 1.08^{(1/12)(12t)} 
= (1.08^{1/12}) ^{12t} 
= 1.0064634^{12t}$
