2 answers:

Surface area and volume are calculated for any three-dimensional geometrical shape. The surface area of any given object is the area or region occupied by the surface of the object. Whereas volume is the amount of space available in an object.

Answer: The Surface Area is a sum total of Area of the planes that form a surface/shape while Volume is the space enclosed within a figure/shape/surface.

The Surface Area is a 2-Dimensional concept with units m², cm² or mm² where as Volume is a 3-Dimensional concept with m³, cm³ or mm³ as units.

A bag contains 5 gold marbles, 10 silver marbles, and 26 black marbles. The rules of the game are as follows: You randomly selec

Answer:

You will most likely lose $1 from playing this game

Step-by-step explanation:

So lets look at the info they gave us...

Gold-$5 (We have 5)

Silver-$2 (We have 10)

Black-$0 (We have 26)

Total Marbles: 41

So now we can find the probability of us picking each color and we will use the color with the highest probability to make the logical assumption of what our profits or loss will be, let's go!

So the chances of us picking gold will be 5/41 because there are only five in the entire batch of 41 marbles, so that seems pretty low

The chances of us picking a silver marble is 10/41 which is pretty decent, we have about a 25% chance, we'll keep that one in mind.

The chances of us picking a black marble is 26/41, which is over 50 percent! We are going to use this color because the probability of us choosing it is over TWICE the probability of the other colors combined!

Now we need to refocus on what the question is asking, "What is the expected profit or loss if you play this game?"

Well we now know that we are expected to pick a black marble, which is worth nothing according to the info they gave us.

Thus, we can make a conclusion that since we earn nothing, and we pay $1 to play the game, we will lose $1.

Hope I helped!!!! :)

1. Factor and simplify: cos² xcsc² x-cos²xcot² x

Vera_Pavlovna [14]

Answer:

Cos² x

Step-by-step explanation:

<h3>Trigonometry:</h3>

$\sf Cos^2 \ x *Csc^2 \ x-Cos^2 \ x *Cot^2 \ x = Cos^2 \ x (Csc^2 \ x - Cot^2 \ x)$

$\sf = Cos^2 \ x \left(\dfrac{1}{Sin^2 \ x} - \dfrac{Cos^2 \ x}{Sin^2 \ x}\right)\\\\= Cos^2 \ x \left(\dfrac{1-Cos^2 \ x}{Sin^2 \ x}\right)\\\\\boxed{\bf Indentity: \ 1 - Cos^2 \ x = Sin^2 \ x}\\\\\\= Cos^2 \ x \left(\dfrac{Sin^2 \ x}{Sin^2 \ x}\right)\\\\= Cos^2 \ x$

laila [671]

Answer:

13 weeks

Given that :

Cost of new tub = $312

Planned saving per week = $24

The number of weeks he'll have to save in other to be able to afford the tub can be obtained using the relation :

Number of weeks = cost of new tub / weekly saving

Number of weeks = $312 / $24

Number of weeks = 13 weeks
