Answer:
.016 kilometers
Step-by-step explanation:
A kilometer is 1000 meters. Divide the length of the markers by 1000 (16/1000) and you get the answer of .016 kilometers.
Linear means in a straight line, non linear n o line
Answer:
=3x+2
Step-by-step explanation:
Let's simplify step-by-step.
6x+1−(3x−1)
Distribute the Negative Sign:
=6x+1+−1(3x−1)
=6x+1+−1(3x)+(−1)(−1)
=6x+1+−3x+1
Combine Like Terms:
=6x+1+−3x+1
=(6x+−3x)+(1+1)
=3x+2
Let's simplify step-by-step.
6x+1−(3x−1)
Distribute the Negative Sign:
=6x+1+−1(3x−1)
=6x+1+−1(3x)+(−1)(−1)
=6x+1+−3x+1
Combine Like Terms:
=6x+1+−3x+1
=(6x+−3x)+(1+1)
Answer:
55 meters squared
Step-by-step explanation:
SA = sum of all the areas of the sides
The pyramid has four faces, which we have to add together:
SA = 3(long face area) + base area
Area of a triangle = 1/2 base * height
Area of the base = 1/2 * 3.5 * 4 = 7 meters squared
Area of a long face = 1/2 * 8 * 4 = 16 meters squared
Coming back to our surface area formula, we can plug those areas in:
SA = 3(long face area) + base area
= 3(16) + 7 = <u>55 meters squared</u>
Answer:
area = 28.26 in²
Step-by-step explanation:
area = 3²(π) = 9(3.14) = 28.26 in²
