(05.01)Daisy is making an abstract painting with two triangles. The dimensions of the painting are shown below: Two triangles share the same height of 10 inches. One triangle has a base of 8 inches, and the other is 12 inches. The total area of the two triangles is square inches. Numerical Answers Expected! Answer for Blank 1:

The total area of the two triangles is 100 square inches.

Solution:

Area of one triangle:

Height = 10 inches

Base = 8 inches

Area of triangle =

                          = 40 square inches

Area of another triangle:

Height = 10 inches

Base = 12 inches

Area of triangle =

                          = 60 square inches

Total area of the two triangles = 40 square inches + 60 square inches

                                                  = 100 square inches

The total area of the two triangles is 100 square inches.

arithmetic sequence: a sequnce in which the diffrence between any two consecutive terms is the same

step-by-step explanation:

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
