Answer:
<h2>
Average speed is 15km/h</h2>
Step-by-step explanation:
Step one:
given data:
total distance =7.5km
time taken= 30 min= 0.5 hours
we know that the average speed is the average distance divided by time taken
Step two:
mathematically expressed as
speed=distance/time
substituting we have
speed=7.5/0.5
speed=15km/hour
Hence the average speed is 15km/h

Answer:
16. x = 11
17. x = 4
Step-by-step explanation:
The triangles of interest are congruent, so corresponding parts have the same measure.
__
16. 2x+2 = x+13
x = 11 . . . . . . . . . subtract x+2 from both sides
__
17. 4x+4 = 3x+8
x = 4 . . . . . . . . . subtract 3x+4 from both sides

Answer:
987 cubic foot
Step-by-step explanation:
we need to find the volume of each of them.
container A = πr²h
=22/7*(10)² * 10
=22/7 * 100 *10
= 22000/7 cubic feet
container B
=πr²h
=22/7 *7*7*14
= 22*7*14
= 2156 cubic foot
22000/7 - 2156 (to find empty space volume)
= 22000- 15092/7
= 6908/7
=986.85... ≈ 987 cubic foot.
