Answer:

Note:
Three-tenths reapeating is 
Sample Response: There is a common ratio of 2/3 between the height of the ball at each bounce. So, the bounce heights form a geometric sequence: 27, 18, 12. Two-thirds of 12 is 8, so on the fourth bounce, the ball will reach a height of 8 feet.
Answer:
95 square meters
Step-by-step explanation:
I am answering this question assuming 19 is the base because it is the longest side on the triangle. (there is no picture provided)
The formula for area of triangle is base * height * 1/2
So 19 * 10 *1/2 is 95.
Answer:
w = -15
Step-by-step explanation:
-5w = 7 - 4w + 8
Grouping like terms together,
-5w+4w = 7+8
-w = 15
w = -15
