0.5*0.5*0.5= 0.125 the volume of one cube
so 0.125* 45 (the total amount of cubes) is 5.625

The answer is 22.5 because the total area is 45 if you count it, and it says each is 1/2.

1/2 * 45 = 22.5.

Help please! I'm just uncertain about what d is.

zalisa [80]

Answer:

Part a) $180\°$

Part b) $180\°$

Part c) $180\°$

Part d) Angle $3$

Part e) Angle $3$

Step-by-step explanation:

we know that

If two angles are supplementary

then

their sum is equal to $180\°$

In this problem

angle 1 and angle 2 are supplementary, and angle 2 and angle 3 are supplementary

$m$ --------> equation A

$m$ --------> equation B

equate equation A and equation B

$m$

Subtract $m$ both sides

$m$

therefore

m<1≅m<3
