=> x < 15+ 7

=> x< 22

What are the solutions of the compound inequality 2d + 3 ≤ –11 or 3d – 9 &gt; 15?
pentagon [3]

Step-by-step explanation:

1.

2d + 3 \leqslant  - 11 \\ 2d \leqslant  - 11 - 3 \\ 2d \leqslant  - 14 \\  \frac{2d}{2}  \leqslant  \frac{ - 14}{2}  \\ d \leqslant - 7

2.

3d - 9 > 15 \\ 3d > 15 + 9 \\ 3d > 24 \\  \frac{3d}{3}  >  \frac{24}{3}  \\ d = 8

Use the formula s = rwt to find the value of the
Vinil7 [7]

Answer:

π/36 sec-1

Step-by-step explanation:

From the question we are given the formula below

s = rwt ..........eqn(1)

Where s= π/3m, r=3 m, t= 4 sec

We were not given value of " w" which implies we are required to find out values of" w"

We can make " w " the subject of the formula from eqn(1)

s = rwt

w= s/(rt)........eqn(2)

Then substitute for the values in eqn(2)

w= (π/3m ) / ( 3m × 4 sec)

= π/36 sec-1

Hence, the value of the

missing variable is π/36 sec-1
