Hi there!
To find the surface area, we need to find the area of all of the faces. The triangle face = 4 x 6, and the rectangular faces = 2(5 x 12) + 1(6 x 12). All we are doing is simply finding the area of each face and adding it together. The area of the triangles = 24, and the area of the rectangles = 192. Then, add the two values to get 216cm^2.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
The answer would be 140° or D because supplementary means the angles add up to 180°. Therefore, 180°-40°=140°
Answer:
CA = Q·CL +I +P
Step-by-step explanation:
Multiply by the denominator, then add the opposite of all terms that are not CA.
Here is the solution for the given problem above.
The formula for getting the distance is distance = rate x time.
Given that the rate is 0.12miles/minute and the time is 9 minutes, we simply substitute the values to the formula.
So distance = 0.12miles/minute x 9 minutes and we get 1.08 miles. So the distance that she can walk for 9 minutes is 1.08 miles. Hope this answers the question.
