Here's the rule you need to know
in order to answer this question:
1 full circle ==> 360 degrees .
Got that ?
Now you could set up a proportion:
(30 degrees) / (0.01 second) = (360 degrees) / (time for full period)
Cross-multiply the proportion:
(30°) · (period) = (360°) · (0.01 sec)
Divide each side by (30°) : Period = (360° · 0.01 sec) / (30°)
= (3.6° · sec) / (30°)
= (3.6 / 30) sec
= 0.12 sec .
___________________________________
Another way to look at it:
30° takes 0.01 second
60° takes 0.02 second
90° takes 0.03 second
120° takes 0.04 second
150° takes 0.05 second
180° takes 0.06 second
210° takes 0.07 second
240° takes 0.08 second
270° takes 0.09 second
300° takes 0.10 second
330° takes 0.11 second
360° takes 0.12 second
Answer:
the answer is 45.6 kg = 45600 g
Answer
Given,
Average speed of Malcolm and Ravi = 260 km/h
Let speed of the Malcolm be X and speed of the Ravi Y.
From the given statement
....(i)
....(ii)
Adding both the equations
3 X = 600
X = 200 km/h
Putting value in equation (i)
Y = 520 - 200
Y = 320 Km/h
Speed of Malcolm = 200 Km/h
Speed of Ravi = 320 Km/h
1) The area of a circle is given by
where r is the radius of the circle. In this problem, we are told that the area is
so we can rearrange the previous equation to calculate the radius:
And now we can find the circumference, by using the formula:
Therefore, the correct answer is D. 75.3984 meters.
2) The volume of a cube is given by:
where L is the length of the edge. In this problem, L=6 cm, therefore the volume of the cube is
and so, the correct answer is A. 216 cu. cm.
By definition, photosynthesis is the process made by green plants, algae and some other forms of bacteria to make their own food by converting carbon dioxide and water into glucose.
So how important is photosynthesis to plants? It is as important as how humans need food in order to survive. Plants also need food and energy to survive and grow.
Not only food is the important matter to be addressed when it comes to photosynthesis. It is also important for plants' cellular respiration. These processes are constantly made by plants throughout their entire life.
