Step-by-step explanation:
Area of Figure
= Area of Parallelogram + Area of Semicircle
= (26)(13) + 0.5π(24/2)²
= 338 + 72π
= 564.2.
Step-by-step explanation:
The speed of sound has nothing to do with "sea level" and sound pressure and without the medium air there is no speed of sound. In SI units with dry air at 20°C (68°F), the speed of sound c is 343 meters per second (m/s). This also equates to 1235 km/h, 767 mph, 1125 feet per second (ft/s), or 666 knots.
Answer: 6!
Step-by-step explanation:
9 / 1.5 = 6. To make sure, 1.5 x 6 = 9
This shows that it is scaled up 6 times larger.
Answer:
2 hours
Step-by-step explanation:
first tap= 3hours
therefore work done is = 1/3
second tap= 6hours
therefore work done = 1/6
so, 1/3+ 1/6
=2/6 + 1/6
=3/6
=1/2
=2/1 hours
=2 hours
