Since the distance is 3.667km and the time is 1/3 of an hour (20 minutes) we take the distance and divide it with time 3.667/20 thus the answer is
0.183 km/hr
Answer:
240, 1800, 2040
Step-by-step explanation:
First find the surface area of the shape - base = 3 x 15 x 2 + 40 x 15 + 40 x 3 x 2 = 930 m ^2
Now find the area of base = 40 x 15 = 600
Now, the cost of painting = 10 pounds for 25 m^2. SO here cost = 600 / 25 x 10 = 24 x 10 = 240 pounds.
Now cost of tiles = 600 x 3 = 1800
Total cost = 1800 +240 = 2040
Hi!
To answer this, simply add all of the values together to get the final answer.
12.99 + 20.99 + 66.49 + 12.06 = 112.53
The answer is 112.53
Hope this helps! :)
Answer:
23˚
Step-by-step explanation:
If x = 10, then angle VYZ = 157 by basic algebra. Knowing that VYZ and WYZ are supplementary angles, we can do 180-157 to find angle WYZ. 180-157 = 23˚
For this case we have that by definition, the arc length of a circle is given by:
![AL = \frac {x * 2 \pi * r} {360}](https://tex.z-dn.net/?f=AL%20%3D%20%5Cfrac%20%7Bx%20%2A%202%20%5Cpi%20%2A%20r%7D%20%7B360%7D)
Where:
x: Represents the angle between JM. According to the figure we have that x = 90 degrees.
![r = \frac {16.4} {2} = 8.2](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%20%7B16.4%7D%20%7B2%7D%20%3D%208.2)
So:
![AL = \frac {90 * 2 \pi * 8.2} {360}\\AL = \frac {90 * 2 * 3.14 * 8.2} {360}\\AL = 12.874](https://tex.z-dn.net/?f=AL%20%3D%20%5Cfrac%20%7B90%20%2A%202%20%5Cpi%20%2A%208.2%7D%20%7B360%7D%5C%5CAL%20%3D%20%5Cfrac%20%7B90%20%2A%202%20%2A%203.14%20%2A%208.2%7D%20%7B360%7D%5C%5CAL%20%3D%2012.874)
