Answer:
B
Step-by-step explanation:
Same here, we do a quick switcharoo on the variables first,
28°
a triangle = 180°
180°-140°= 40°
180°-68°= 112°
180°-112°-40°= 28°
Answer:
D
Step-by-step explanation:
This is exponential growth, and to my understanding, the format goes:
<em>initial amount (percent growth/ decay)^time</em>
percent growth = (<em>decimal percent + 1)</em>
<em>percent decay = (1 - decimal percent) </em>
Your equation:
1500(1.02)^t
Using the above format, 1500 appears to be the initial amount, which increases by 2% per annum.
i think
340 is the total after the two transactions
