Answer:
5/8
Step-by-step explanation:
The area of the smaller circles is proportional to the square of the ratio of their diameters. The two smallest circles have diameters equal to 1/4 the diameter of the largest circle. Hence their areas are (1/4)^2 = 1/16 of that of the largest circle.
Similarly, the medium circle has a diameter half that of the largest circle, so its area is (1/2)^2 = 1/4 of the are of the largest circle.
The smaller circles subtract 2×1/16 +1/4 = 3/8 of the area of the largest circle. Then the shading is 1-3/8 = 5/8 of the area of the largest circle.
An integer that would work is 14 so -3 + 14 = -11
Answer:
Current price index number = 455
Step-by-step explanation:
Given:
Current cost of gasoline = $2.58 per gallon
1975 price of gasoline = 56.7 Cents = 56.7 / 100 = $0.567 per gallon
Find:
Current price index number = ?
Computation:
Current price index number = (Current cost / Reference cost) 100
Current price index number = ($2.58 / $0.567)100
Current price index number = (4.55)100
Current price index number = 455
Answer:
2 and 5
Point and line.
Step-by-step explanation:
In geometry, there are many terms and jargons Mathematicians make use of.
Angle is one of the term used in geometry which depicts any form of inclination.
Segment is also use to analyze and to solve many questions.
Lines are used to join one segment or the other.
Point and ray are also used but are majorly used in optics
Asking that Which of the following do not have precise definitions in geometry.
The best answer are point and line.
Because there is no specific definition for the two variables.
