Aresearch student measured the age of an ice layer at 70 m depth as 425 years. the accepted value reported is 427 years. what is the percent error of students value?

0.47%.

Step-by-step explanation:

We have been given that a research student measured the age of an ice layer at 70 m depth as 425 years. The accepted value reported is 427 years.

We will use error percent formula to solve our given problem.

Rounding to two decimal places:

Therefore, the percent error of students value is approximately 0.47%.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
