Non of the lines are the same, the equations are dependent linear equations.
The area is the what fills the shape and the circumference is the outline or perimeter. The circumference is mainly used for circles.
Hope that helps!!!!!
Just plug in the 30° into that equation.
<span>A(30°) = 16sin(30°)(cos(30°) + 1) </span>
<span> = 16(1/2)(1 + √3/2) </span>
<span> = Approx 14.9 in² </span>
<span>So A is the answer. </span>
Answer:
B) 1/2
Step-by-step explanation:
If Ethan rolls a 6 sided number cube, the probability that he gets a number less than 4 is 1/2.
Less than 4: 3,2, or 1.
3 is half of 6.
Therefore it is 1/2 or 50%
Ok, so if you’re saying -18=r-3, then first you need to add 3 to each side so you can move the 3 with the -18 so you can isolate r. (Leave it by itself). So now your equation is -18+3=r. Next, combine like terms, so do -18+3, which is -15. Now you have -15=r, so r is equal to -15.
