The answer is 20/3 first you set a variable x and 30x=200 divid both side by 30 and get the final answer
First one:
cos(A)=AC/AB=3/4.24
cos(B)=BC/AB=3/4.24
Cos(A)/cos(B)=AC/AB / (BC/AB) = AC/AB * AB/BC = AC/BC=3/3=1
Second one:
To solve this problem, we have to ASSUME AFE is a straight line, i.e. angle EFB is 90 degrees. (this is not explicitly given).
If that's the case, AE is a transversal of parallel lines AB and DE.
And Angle A is congruent to angle E (alternate interior angles).
Therefore sin(A)=sin(E)=0.5

Hi there! The answer is B.

Subtract 6r from both sides.

Divide both sides of the inequality by -1. Remember that dividing by a negative makes the sign flip.

Therefore, the solution must be bigger than or equal to 8. From the given solution set, the answer is B. {8, 9, 10}

Answer:
mold
Step-by-step explanation:
Male betta fish will place the eggs into a bubble nest, which he will create. The baby betta fish will hatch in about three days. As they hatch, male betta fish will watch and remain under the bubble nest, catching any eggs that fall out. Once hatched, the babies are called "fry" and are very tiny.
