4 friends are going to sit together in a roller-coaster car that has 4 seats, in how many different arrangements can they sit? (I've done this equation before, it's very simple)
4 people can go in the first seat
there are 3 left to pick for the nest
then, 2 left to pick for the last
then 1 for the final one
so there are 4 x 3 x 2 x 1 choices
Answer:
Multiplying by the height h we get
volume = π r 2 h
where:
π is Pi, approximately 3.142
r is the radius of the circular end of the cylinder
h height of the cylinder

I love algebra anyways
The ans is in the picture with the steps how i got it
(hope this helps can i plz have brainlist :D hehe)
Step-by-step explanation:
Hi there!
Tangent is a trigonometry ratio, and it is the value of the side opposite the angle over the side adjacent to the angle.
The side that is opposite angle B is side CA which is equal to 2.
The side that is adjacent to angle B is side CB which is equal to 1.
Therefore, the tangent ratio for angle B is 2/1.
(The adjacent side cannot be side BA because it is the hypotenuse.)
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer:
The correct answer is two triangles.
Step-by-step explanation:
In ▲ABC, a = 48.6, c = 41.7, C = 23°
.
Thus this information gives two distinct triangles.
The first triangle is an acute triangle in quadrant 1. The angle measures of this triangle are ∠A = 27.09° and ∠B = 129.91°. The lengths of the sides of this triangle are a = 48.6; b = 81.86; c = 41.7.
The second triangle is an obtuse triangle in quadrant 2. The angle measures of the other triangle are ∠A = 152.91° and ∠B = 4.09°. The lengths of the sides of this triangle are a = 48.6; b = 7.61 ; c = 41.7.
