Answer:
%
Step-by-step explanation:
Given: Jocelyn calculates that see will take 105 minutes to run 7 miles. She runs the distance in 84 minutes.
To find: Jillian’s percent error
Solution:
Actual time taken by Jocelyn to run 7 miles = 84 minutes
Approximate time taken by Jocelyn to run 7 miles = 105 minutes
Error = 
minutes
Percent error = error/(Actual time taken) × (100) = 
Answer:
Step-by-step explanation:
The first step is to determine the areas of the inner and the bigger circles.
The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
Considering the inner circle,
diameter = 148.4 cm
Radius = 3 inches
Area = 3.14 × 3² = 28.26 inches²
Considering the bigger circle,
Radius = 7 inches
Area = 3.14 × 7² = 153.86 inches²
The area between the bigger and inner circles is
153.86 - 28.26 = 125.6 inches²
Probability = number of favourable outcome/number of total outcome.
the probability you land inside the bigger circle but outside smaller circle is
125.6/153.86 = 0.82
B = 120 because it is in your sum
Answer:
30%
Step-by-step explanation:
Meagan completed 14/20 math problems. 14÷20 is 0.7
So she completed 70% of those math problems. The question is How many does she have left?
So she has 30% left to complete.
