Answer:
A
Step-by-step explanation:
In geometry (or math in general), when you do a reflection, rotation, or translation the size or length of the lines don't change. Think about it this way: if I have a log and I bring it into the bathroom with me (don't ask why idk) and hold it up in from of the mirror, what will happen? It will look the same length (and people will think I'm crazy for bringing a log into the restroom with me... but I digress).
Hi- I'm not sure what they mean by place value. But hopefully this helps.
A: Lee needs 370 pencils and wants to buy them by the box. There are 10 in a box so we need to divide 370 by 10.
370/10= 37
So he would need to buy 37 boxes
B: A carton has 10 boxes and each box has 10 pencils so first we need to find out how many pencils are in a carton:
10*10=100
To get 370 pencils, Lee would have to buy 4 cartons totaling 400 pencils

See explanation below
Step-by-step explanation:
<em>R(x,y) means x and y are related</em> according to previous established relation.
For example R(x,y) could be “x<y” if x, y are integer numbers, or R(x,y) could be “x and y are friends” if x and y are people.
<em>The set which x and y belongs to, need not be the same.</em>
<em>∀x∀y R(x, y) means: for every x in a set S and every y in a set T, x and y are related.
</em>
The logical conector “and” is commutative, that is to say, the sentence “for every x in a set S and every y in a set T x and y are related” is the same as “for every y in a set T and every x in a set S x and y are related”.
This last sentence is ∀y∀x R(x, y).
So, they are the same thing.
Answer:
Step-by-step explanation:
Let’s break this apart.
Box= 12cm x 8cm x 6cm
Cube= 2cm x 2cm x 2cm
How many cubes fit in the box?
calculate the volume of the box. To do this, multiply the length by the width by the height (L x W x H)
12 x 8 x 6 = 576cm cubed
2. Calculate the volume of the cube. Once again we multiply L x W x H
2 x 2 x 2 = 8cm cubed
3. Next we divide the volume of the box by the volume of the cube
576 / 8 = 72 cubes
Therefore, it would take 72 cubes to fill a box.
