SOMEONE KNOW THIS, IS STUDY ISLAND Seraphina is driving two hours to visit her family. For the first hour, she traveled at a speed of 61 miles per hour. Then, in the second hour, she traveled at a speed of 66 miles per hour. What is the percentage increase of Seraphina's speed? If necessary, round to the nearest tenth of a percent

a is the correct

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

x equals 1

step-by-step explanation:

f(4)=f(×)

x=1

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
