Answer:

135

Step-by-step explanation:

if mK is 90 then mD is 60 and mS is 30. since the new point is in the middle of the triangle divide 60 and 30 by 2. Now mD is 30 and Ms is 15 so 30+15=45 so 180-45=135

120 cubes

Step-by-step explanation:

Find the volume of the prism and then divide it by the volume of one cube (which is 1/27 cm):

V = length*width*height = (5/3 cm)(4/3 cm)(2 cm) = 40/9 cm³.

Dividing this result by 1/27 yields

40 27 40*3

If a = b + 2, then (b - a)⁴ = ?

Hatshy [7]

Use substitution.

anywhere you see "a" , than you would plug in b + 2 in for it so....

(b - (b + 2)^4

now take the negative sign and distribute it "+"

so b - b is 0, than 0 - (-2) is -2.

so what is (-2)^4 ????? it would become positive 16
