Three students need to produce a prime factorization of 48. Donna states that the first factors in the tree should be 6 and 8. L
Gennadij [26K]
If we start with 6 and 8, we can break 6 up into 2*3 and 8 into 2*2*2, thus getting a prime factorization of 2*2*2*2*3, or 2^4 *3.

If we begin with 4 and 12, 4 breaks into 2*2 and 12 into 2*2*3, so the prime factorization of 48 is still 2^4 *3.

The starting factors do not matter, since the answer comes out to be the same. There is exactly one correct answer- it doesn't matter how it's found.

Hope this helps! :)

A recipe for cookies calls for 3 1/4 cups of sugar. Amy has already put in 3 1/9 cups. How many more cups does she need to put i
sammy [17]
So 3 and 1/4 is equal to 4/4+4/4+4/4+1/4=13/4

so she put in 3 and 1/9 or 9/9+9/9+9/9+1/9 or 28/9

28/9+x=13/4
13/4-28/9=x

so we convert so that the bottom numbers are the same

a short cut is 3 and 1/4+x=3 and 1/9 
3 1/9+x=3 1/4
subtract 3 from both sides
1/9+x=1/4
subtract 1/4 from both sides
x=1/4-1/9
convert bottom number to same thing
1/9=4/36
1/4=9/36
x=9/36-4/36
x=5/36
5/36 cups

Find the reference angle for 404 degrees
Hitman42 [59]
It would have to be 44°. If you go around 360° nothing happens. So subtract 404°-360° and you get 44°. 44°<90° from the x-axis so we are done.

Please help! The question is in the pic!

Answer:

B. -x + 8

Step-by-step explanation:

Given expression

\dfrac{8-4(x-6)}{4}

Consider the numerator 8-4(x-6).

First, use distributive property:

8-4(x-6)=8-(4x-24)

Open the brackets:

8-(4x-24)=8-4x+24

Combine the like terms:

8-4x+24=(8+24)-4x=32-4x

Again use distributive property:

32-4x=4\cdot 8-4x=4(8-x)

Now, the expression is

\dfrac{4(8-x)}{4}=8-x\ \text{or}\ -x+8
