X > 1 because you just add the 7 to the other side.
To transform the left side of the equation into the right side under the interval (0 < θ < π/2), the missing trigonometric identity to complete the equation is cos2 θ = 1- sin2 θ. This is a trigonometric identity specifically under the <span>Pythagorean Identities</span>
Answer:
A
Step-by-step explanation:
Find the common factors between the 2:
2πr + 4πrh
2 (πr+2πrh)
2πr (1 + 2h)
Answer:
C) 160
Step-by-step explanation:
Set up a proportion:
= 
Cross multiply and solve for x:
15x = 3600
x = 240
This means in 400 marbles, 240 are purple.
To find how many are not purple, subtract 240 from 400:
400 - 240
= 160 marbles
So, 160 marbles are not purple
