Simple interest is given by the formula a = p + p r t a = p + p r t . where a a is the balance of the account after t t years, and p p is the starting principal invested at an annual percentage rate of r r , expressed as a decimal. dustin is investing money into a savings account that pays 5% simple interest, and plans to leave it there for 10 years. determine what dustin needs to deposit now in order to have a balance of $20,000 in his savings account after 10 years. dustin will have to invest $ now in order to have a balance of $20,000 in his savings account after 10 years. round your answer to the nearest dollar.

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.
