The area of a triangle ( one of the sides) is 1/2 x base x height
base = 16, height = 19
Area = 1/2 x 16 x 19 = 152 square units.
There are 4 sides: 152 * 4 = 608 square units
The area of the bottom square is 16 x 16 = 256 square units.
Total area = 608 + 256 = 864 square units.
The answer is D.
(x + 4) + (y - 5) = 7²
(x + 4) + (y - 5) = 49
It's always in this basic form.
Answer: b
Step-by-step explanation: because its 50/50
B(t) = 5000 * 2^(-0.05t)
<span>2000 = 5000 * 2^(-0.05t) , div by 5000 </span>
<span>0.4 = 2^(-0.05t) , ln on both sides => </span>
<span>ln0.4 = (-0.05t)* ln2 </span>
<span>(ln0.4)/ln2) /(-0.05) = t </span>
<span>t = 26.43 </span>
<span>After 27 years</span>
