Find the total of principal plus interest on a principle of $870 interest rate of 3% time is nine months

$38666.67

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3%/100 = 0.03 per year,

putting time into years for simplicity,

9 months ÷ 12 months/year = 0.75 years,

then, solving our equation

P = 870 / ( 0.03 × 0.75 ) = 38666.666666667

P = $ 38,666.67

The principal required to

accumulate interest of $ 870.00

on a rate of 3% per year for 0.75 years (9 months) is $ 38,666.67.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
