Remember
anything times 1=same thing and

x/x=1 where x=x
so
mutliply both fractions by what makes the bottom numbers 40
1/5
5 times what=40?
answer is 8
multily by 1 or 8/8
1/5 times 8/8=8/40

7/8
8 is bottom
8 times what is 40? answer is 5
multiply by 1 or 5/5
7/8 times 5/5=35/40
1/5=8/40
7/8=35/40
they are not equal

No because you multiply 1/5 by 8 ans you will get 8/40 mean while you got 7/8 and multiply that by 5 and you get 35/40 so the answer is no

The whole numbers from 10-12 are paired with their factors explain why this pairing doesnt describe a function

myrzilka [38]

Answer:

As given whole numbers from 10 - 12 are paired with their factors.

factor of ,10=1,2,5,10 → (10,1),(10,2),(10,5)(10,10)

factor of 11=1, 11 → (11,1),(11,11)

factor of 12=1,2,3,4,6,12→ (12,1),(12,2),(12,3),(12,4),(12,6),(12,12)

As we know for an ordered pair to be function Every element in the domain must have a unique image, i.e it can't have more than one image.

→ As element 10, have four images,which are 1,2,5,10 so it can,t be a function.

Similarly element 11 have two images 1,11 so it can't be a function.

Element 12 have six images 1,2,3,4,6,12, so it also can't be written as function.

The distance between the points (12,9) and (0,4) is A) 14 units B) 13 units C) 15 units D) 16 units

Juliette [100K]

Answer:

Option B 13 units is correct.

Step-by-step explanation:

The formula used to find distance between 2 points is:

$d(P1,P2)=\sqrt{(x_{2} -x_{1})^2 + (y_{2} -y_{1})^2 }$

x₁ = 12 x₂ = 0 y₁= 9 and y₂=4

Putting values in the formula:

$=\sqrt{(0-12)^2+(4-9)^2}\\=\sqrt{(-12)^2+(-5)^2}\\=\sqrt{144+25} \\=\sqrt{169} \\=13$

So, Option B 13 units is correct.

Answer:

$50 - d = $22.50

A prism is completely filled with 96 cubes that have edge length of 1/2 cm.

ch4aika [34]

I know this is kinda late, but...

You can solve this easily as long as you remember how to find the volume of a cube. v=a^3, when a means length. The length is 1/2 cm, or .5 cm.
So, v+.5^3, which equals .125 cm. Each cube has a that volume. Now, multiply that by how many actual cubes there are, 96.

96 * .125 = 12
