They are all (SAS)side angle side except for the bottom right one. This is because the question does not give the little ticks to show that one side is the same as the other. It is not good enough to assume they are congruent without proof.
The sum of 3,748 and 3,242 is 6,990.
Answer:
8%
Step-by-step explanation:
So we have two investments. The first is 500 with an interest rate of x while 2000 has an interest rate of x+.005 (.005 is .5 %),
annual interest means it gets interest once a year, it then says in total, after one year, so one time getting interest he gets 210 total, so in total the money is 500 + 2000 + 210. So let's set up an equation with all this
500x + 2000(x+.005) = 2710
500x + 2000x + 10 = 2710
2500x = 2700
x = 1.08
So that means we multiply 500 by 1.08, which represents 8% and 2000 by 1.085. But the question is just asking for the interest rate for 500 so the answer is 8%
