Answer:

2) The amount of paper it takes to wrap a gift

3) Painting a wooden box on all sides

5) The amount of aluminum it takes to make a soda can

Step-by-step explanation:

Volume is how much something can hold, and were looking for the "Surface Area". So, It can't be "The amount of water held in a paper cup in the shape of a cone", "The amount of water a rectangular swimming pool will hold", and Filling a sand box with sand" because these are finding the volume.

Have a great day! :D

Answer:

C. 342

Step-by-step explanation:

This year, 150% of last year's tickets were sold.

Last year, 228 tickets were sold.

150% as a fraction is 150/100

To find the amount of tickets sold this year, we take the 150/100 and multiply it by 228:

150/100*228= 342 tickets

Which is the first step in solving<br> X-2 = 2?

Vanyuwa [196]

Answer:

The first step is to find a number that when subtracted from 2 gives you 2.

Step-by-step explanation:

The algebraic part of this problem would be to add the -2 (adding 2 to both sides) to both sides, so

first x-2=2, then x-2(+2)=2(+2) which would give us,

x=4

*note: the parenthesis are just to show that we are adding the 2, to make it more understandable.

What additional information do you need to prove NOP=QSR?

Lorico [155]

After careful consideration i think I have an answer...
So if you notice, These two triangles are a reflection of each other.
Now even though these two triangles equal one another, we still have to consider the fact that they are different. (one side is the opposite of another)
So lets just name all the sides that equal each other.
∠N = ∠Q
NO = QS
QR = NP
PO = SR
∠S = ∠O
∠P = ∠R

(by the way i'm going to be saying {the reflective side} every time i want to refer to the side with the two lines :P) - so bare with me.

So therefore this would mean that ∠P = ∠S would be false, since one angle is from the side that is reflected and the other isn't. Makes sense?

So lets look over at the answers...

A.) PN = SQ
For this answer choice, PN is on the non reflective side, while SQ is on the reflective side. Soooo... This answer choice is wrong.

B.) NO = QR
NO is part of the unreflective side, while QR is part of the reflective side.
Therefore this answer is wrong. They must be part of the same side.

C.) ∠P = ∠S
∠P is on the unreflective side, while angle ∠S is on the reflective side.
There fore this answer is also wrong.

D.) ∠O = ∠S
Now ∠O is on the reflective side while ∠S is on the reflective as well.
There fore this answer is correct .

YOUR ANSWER IS.
D.) ∠O = ∠S
