Answer:
length of side of newly formed cube = 13.13cm
Step-by-step explanation:
the volume of the rectangular metal block (V)=
length (L) × width (B) × height (H)
=》V = 27 × 7 × 12
=》V = 2268 cubic cm
and if it is melted and casted into a metal cube, then the volume remains the same
so, volume of cube = 2268 cubic cm
now,
let the measures of sides of the cube formed be a
volume of cube (V) =
=》
=》
=》
Answer:
0i + 10j, or just 10j
Step-by-step explanation:
Vector u = <6, -4> and vector v = <12, 2>.
We are to find v - 2u, which is:
<12, 2> - 2<6, -4>. We combine x components and y components to obtain:
<12-12, 2+8>, or <0, 10>.
In terms of i and j, that'd be 0i + 10j, or just 10j.
Answer:
Step-by-step explanation:
Set this up as a proportion
20/8 = 15/vx Cross multiply
20*vx = 8 * 15
20 * vx = 120 Divide by 20
vx = 6
