Answer:
40
Step-by-step explanation:
if you used cross products you'd pair 8 with 100 and n with 20
That written out would be 8(100)=20n
8(100)=800
800=20n
Divide on both sides
800/20=40
20/20 (cancels out)
Therefore n=40
The area is 113.1m If you want to double check go on google and look up surface area of a sphere. A calculator will come up. Hope this helped.
Answer: 34 meters.
Step-by-step explanation;
Step One. Find the value of the width. Use an equation with w representing the width and the two values you already have. 9 meters x w = 72 square meters.
Step Two. Solve for width. This is w = 8.
Step Three. Use the value for width in a perimeter formula to calculate the perimeter; 9(2) + 8(2). <em>This is 34 meters for perimeter</em>.
Let h = Hannah's age.
Hannah is older than her sibling, and their ages are consecutive odd integers. Therefore, h = an odd number and the sibling's age = h-2.
The sum of their ages is 92, therefore
h + (h-2) = 92
2h - 2 = 92
2h = 94
h = 47 years
Answer:
The equation to find Hannah's age is 2h - 2 = 92.
This yields Hannah's age as 47 years.
