The answer is 56! How you do this, is you take 80, and you multiply it by 7. Then you divide that answer by 10. Then you have your answer! I’m really bad at math but I do know how to do that!
This is exponential decay which can be expressed as:
y=ab^t, y=final value, a=initial value, b=rate, t=time
In this case a=25000, r=(100-20)/100=0.8 so
y=25000(0.8^t), so in 4.5 years...
y=25000(0.8^4.5)
y≈$9158.93 (to nearest cent)
Answer:
its the last one
Step-by-step explanation:
Solution:
<u>We know that:</u>
<em>Since we are already given the base and the height, we can substitute them into the formula to find the area of the triangle.</em>
<u>Cancel out the "2" by dividing it by 18.</u>
<u>Simplify the multiplication.</u>
