Step-by-step explanation:
See attached
As we see this is a polygon with sides of AB=BC=AE and CD=DE
- Sides AB=BC=AE equal to 8
- Sides CD=DE =
= 5
Area is the sum of areas of a square ABCE with side 8 and a triangle CDE with base of 8 and height of 3:
- Area = 8*8 + 1/2*8*3 = 64 + 12 = 76
- Perimeter = 8*3 + 5*2 = 24 + 10 = 34
Answer:
1000 times greater
Step-by-step explanation:
9.6 * 10^-2 / 9.6 * 10^-5
= (9.6 / 9.6) * (10^-2 / 10^-5)
= 1 * 10^(-2 -( -5))
= 10^3
= 1000
Answer:
- Melissa: 30
- Ryan: 23
- Chau: 69
Step-by-step explanation:
Let r represent the number of messages Ryan sent. Then Chau sent 3r and Melissa sent r+7. Their total was ...
(r+7) +(r) +(3r) = 122
5r +7 = 122 . . . . . collect terms
5r = 115 . . . . . . . . subtract 7
r = 23 . . . . . . . . . . divide by 5
Ryan sent 23, Melissa sent 30, and Chau sent 69 text messages.
