If factors are only rounded up, then the estimate is an overestimate. If factors are only rounded down, then the estimate is an underestimate. When some factors are rounded up and some are rounded down, it is harder to tell whether the estimate is an overestimate or an underestimate.
Answer:
2.5/5V
Step-by-step explanation:
Given the expression for hang time t = 5Vh
A kite sailor has a hang time of 2.5 secs
Height of the kite’s sailor’s jump = ?
Therefore 2.5 = 5Vh
Divide both sides by 5V
2.5/5V = h
h = 2.5/5V

Answer: 39 untits 2
Step-by-step explanation:
Hi, to answer this question, first we have to calculate the perimeter (sum of sides) of the triangle:
Perimeter: 7+6+9.22 = 22.22 units
Then we have to apply the circumference (C) formula:
C = π x diameter
Since C = perimeter of the triangle:
22.22 = 3.14 d
22.22 /3.14 =d
7.08 = d
Finally, we apply the next formula:
Area of a circle = π (d/2)^2
Replacing:
A = 3.14 (7.08/2)^2 = 39.30 units2 = 39 units 2
