Answer:
The sixth number in series is 13.
Step-by-step explanation:
Given series : 3, -6, 12, 4, 20, ?
The pattern followed by the series is:
The first number = 3
Second number = 3 - 9 = - 6
Third number = - 6 + (9 ×2) = -6 + 18 = 12
Fourth number = 12 - 8 = 4
Fifth number = 4 + (8 ×2) = 20
Sixth number = 20 - 7 = 13
Seventh number = 13 + (7 ×2) = 13 + 14 = 27 and so on.
So as per the above pattern, the sixth number in the series is 13.
Answer:
Step-by-step explanation:
Let x represent the length of the shorter base in inches. Then the longer base has length x+6. The area of the trapezoid is given by the formula ...
A = (1/2)(b1 +b2)h
Filling in the values we know, we have ...
48 = (1/2)(x +(x+6))(6)
16 = 2x +6 . . . . . divide by 3
10 = 2x . . . . . . . . subtract 6
5 = x . . . . . . . . . . divide by 2
(x+6) = 11 . . . . . . find the longer base
The lengths of the bases are 5 inches and 11 inches. We found them by solving an equation relating area to base length.
The answer is 91.44 meters
Every point on a line satisfies the equation of that line.
If two lines intersect at one point, that point is a point on both lines, so it must satisfy both lines. Since two different lines can intersect at most at one point, that point is the only point that makes the two equations true.
