Mandy: $16.25
Jermey: $16.25 + $3.40 = $19.65
Lily: $19.65 x 2 = $39.30
For Lily you would take the total of Jermey and times it by 2.
Answer:
Unit rate: 21feet / 7seconds = 3 feet per second.
3 feet per second * 5 seconds = 15 feet
21 feet + 15 feet =36 feet
You are 36 feet from the surface.
Step-by-step explanation:
Answer: 5.14 cu in
Step-by-step explanation:
1/2 (π × d) + d, where d is the diameter of the semi
Perimeter = 1/2 (3.14 x 2) + 2
= 1/2 * 6.28 + 2
= 3.14 + 2

Answer: 24/25</h3>
====================================================
Explanation:
If sin(x) = 3/5, then cos(x) = 4/5 through the use of the trig identity
sin^2(x) + cos^2(x) = 1
This is assuming that x is in quadrant Q1.
Plug those values into the identity below and simplify.
sin(2x) = 2*sin(x)*cos(x)
sin(2x) = 2*(3/5)*(4/5)
sin(2x) = 24/25
