Answer:
Front, 60, back 60, right, 30, left, 30. And the triangle's surface area is 15 + 15 = 30, And 20 / 2 = 10. SO the surface area is 190 cm^2
Step-by-step explanation:
Positive integer: 2
2*2 = 4
4 + 6 = 10
10/2 = 5
5-2 = 3
Answer: It will take about 77 years (76.8 years).
Step-by-step explanation: Time is given by the equation: N=No.e^kt. You know that the concentration has to be 15% from the original so N=15 and No=100. To determine k, you have to look at the half-life. k=ln(0.5)/half-life time. For 28 years, k=-0.0247. Replacing it back into the N=No.e^kt equation, the answer will be 76.8 years.
