X + 2 = 12
subtract both sides by 2
x = 10
Diameter of the basketball rim = 18 inchesCircumference of the standard basketball = 30 inches
Area of circle = π r²
Basketball rim = 3.14 * (18/2)² = 3.14 * 9² = 3.14 * 81 = 254.34 in²
Circumference of a circle = 2 π r30 = 2 * 3.14 * rr = 30 / (2*3.14) = 30 / 6.28 = 4.78 inches
Standard basketball = 3.14 * (4.78)² = 3.14 * 22.85 = 71.75 in²
254.34 - 71.75 = 182.59 in²
Answer: 701
Step-by-step explanation:
A heptagon has 7 sides, therfore a regular heptagon will have 7 equal sides
n = 7 (number of sides)
s = 13.9 (length of each sides of the heptagon)
r = 14.4 (The apothem)
The area of the regular heptagon can be calculated by:
Area = ½ n × s × r
Area = ½ × 7 × 13.9 × 14.4
Area = 700.56 square units
To the nearest whole number, will be:
Area = 701 square units
Answer:
x + y =90
Step-by-step explanation:
So to find any angle in a complementary set you would subtract the angle given by 90.
Easy way to remember what complementary means is the C is like the curve of 9 in 90 and in supplementary the S is like half a 8 in 180.
Answer:
Step-by-step explanation:
Given a second order polynomial expressed by the following equation:
This polynomial has roots 
such that 
, given by the following formulas:
In this problem, the sum S of the solutions of a quadratic equation is:
So
They have the same denominators, so we can keep the denominators and sum the numerators.
