Answer:
About 30
Step-by-step explanation:
The value 239.63 rounds to 240
The value 7.51 rounds to 8
Divide 240 over 8 and we get 240/8 = 30
H is the altitude of a right triangle, so h²=AD*DC=(20-4)*4=64
h=√64=8
D is the correct answer.
The answer is 1:13 you have to divide
Answer:
12762.72 cubic meters
Step-by-step explanation:
The volume of a cylinder is denoted by the formula:
, where r is the radius and h is the height.
Here, we see that the height h = 11.5 m. We also see that the diameter is 37.6 meters. Since diameter = 2 * radius, we can divide this number by 2 to get the radius: r = 37.6/2 = 18.8 meters.
Now substitute these values into the equation:
cubic meters

Answer:
x = 10°
Step-by-step explanation:
ZA + ZB = 90°
50° + 4x = 90°
4x = 90° - 50°
4x = 40°
x = 10°
