Answer:

7 different cubes

Step-by-step explanation:

Given: Alejandro has 64-centimeter cubes.

We know, cube is three dimentional solid object

Now, using 64 centimeter cubes to build cubes with  different side lengths.

∴ Finding the different possible 3 multiple(dimention) of 64 to know the number of cubes.

64= 64\times 1\times 1

64= 32\times 2\times 1\\64= 16\times 4\times 1\\64= 16\times 2\times 2\\64= 8\times 8\times 1\\64= 8\times 4\times 2\\64= 4\times 4\times 4

Hence, we can have 7 different cubes with 64 cm cubes.

H(4 1/2, -3 1/4) x (3 3/4, -1 3/4) what the midpoint of hx
shtirl [24]

Answer:

(3 7/8, 2 3/4)

Step-by-step explanation:

To find the midpoint, the formula is (x1-x2)/2 and (y1-y2)/2. So, in this case, our x1 is 4 1/2 and our x2 is -3 1/4. Subtract x2 from x1 and you will get 7 3/4. Then, divide by 2 to get 3 7/8. This is our x-coordinate.

Our y1 is 3 3/4 and our y2 is -1 3/4. Subtract y2 from y1 to get 5 1/2. Then divide by two to get 2 3/4. This is our y-coordinate.

Now we have our x and y coordinates.

(3 7/8, 2 3/4)

Explain how the commutative property of addition,the Associative property of addition and mental math can help you find 75.2+(57
4vir4ik [10]

Answer: The sum of 75.2+(57.376+24.8) is 157.376.

Explanation:

The commutative property of addition states that,

a+b=b+a

The associative property of addition states that,

a+(b+c)=(a+b)+a

The given expression is 75.2+(57.376+24.8).

First use commutative property of addition in the parenthesis.

75.2+(57.376+24.8)=75.2+(24.8+57.376)

Now use associative property of addition.

75.2+(24.8+57.376)=(75.2+24.8)+57.376

Now simplify the expression,

(75.2+24.8)+57.376=100+57.376

(75.2+24.8)+57.376=157.376

Therefore, the sum of 75.2+(57.376+24.8) is 157.376.
