Use the simple interest formula to determine the missing value. p=?, r=6%, t=9 months, i=81

P = 1800

Step-by-step explanation:

The formula to calculate simple interest (I) is

I = ( note that time is in years ), thus

9 months = = = 0.75 years

Thus

81 = ( multiply both sides by 100 )

8100 = 4.5P ( divide both sides by 4.5 )

P = 1800

126.66 m²

step-by-step explanation:

the pertinent area formula is a = πr², where r is the radius.

here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
