When Priscilla was born her parents put $8000 into a college fund account that earns 9% simple interest. Find the total amount in the account after 18 years

P is the principal amount, $8000.00.

r is the interest rate, 9% per year, or in decimal form, 9/100=0.09.

t is the time involved, 18year(s) time periods.

So, t is 18year time periods.

To find the simple interest, we multiply 8000 × 0.09 × 18 to get that:

The interest is: $12960.00

∠1≅∠2 by the alternate exterior angles theorem.

step-by-step explanation:

given, a ∥ b and ∠1 ≅ ∠3 .we have to prove that e ∥ f

we know that ∠1≅∠3 and that a || b because they are given. we see that by the alternate exterior angles theorem. therefore, ∠2≅∠3 by the transitive property. so, we can conclude that e || f by the converse alternate exterior angles theorem.

we have to fill the missing statement.

transitivity property states that if a = b and b = c, then a = c.

now, given ∠1≅∠3 and by transitivity property ∠2≅∠3 .

hence, to apply transitivity property one angle must be common which is not in result after applying this property which is ∠1.

the only options in which ∠1 is present are ∠1 and ∠2, ∠1 and ∠4

∠1 and ∠4 is not possible ∵ after applying transitivity we didn't get ∠4.

hence, the missing statement is ∠1≅∠2.

so, ∠1≅∠2 by the alternate exterior angles theorem.

the aswere is the one with all 8's and the second one is with the 10,8 and 6
