28.9

Step-by-step explanation:

Multiply the denominator by the number on the other side. This will give you 28.9 as t. To check your work, divide 28.9/8.5. This will give you 3.4.

Answer:

$x=0.75, y=-0.25$

Step-by-step explanation:

We can add the two equations to eliminate $y$ and solve for $x$ .

$x+y+x-y=0.5+1$

$2x=1.5$

$x=0.75$

Now, we can find for $y$ by using substitution:

$x+y=0.5$ (given)

$0.75+y=0.5$

$y=-0.25$

Hope this helps :)

A rectangular picture frame measures 63 cm by 63 cm. What is the perimeter or distance around the picture frame in meters? m

Natalija [7]

Hi!

We need the perimeter in meters, so we have to turn cm into m.
63 cm = 0.63 m

The perimeter is the sum of all side measures:
P = 0.63 + 0.63 + 0.63 + 0.63
P = 4 * 0.63
P = 2.52 m

How many 1/2 unit cubes can fit in a a prism with a volume of 6 cubic units

AlekseyPX

Answer:

48 cubes

Step-by-step explanation:

step 1

Find the volume of one 1/2 unit cube

The volume of the cube is given by

$V=b^3$

where

b is the length side of the cube

we have

$b=\frac{1}{2}\ units$

substitute

$V=(\frac{1}{2})^3$

$V=\frac{1}{8}\ units^3$

step 2

Divide the volume of the prism by the volume of one cube

$6:\frac{1}{8}=6(8)=48\ cubes$
