Answer:
Hi there!
Your answer is:
the number is 68
Step-by-step explanation:
(18-n) /2 = -25
×2
(18-n) = -50
-18
-n = -68
/-1
n= 68
Plug it back in!
(18-68) /2 = -25 ???
-50/2 = -25 ✓✓✓
Hope this helps
For the sake of it c=x
13.50+9x=36
36-13.50=22.5
9x=22.5
22.5/9=2.5
X=2.5
4. all for angles need to equal 360
90 +90 + 42 = 222
360-222 = 138
y = 138 degrees
x - 42 degrees
6. x = arctan(8/4) = 63.43 degrees ( round as needed)
y = 16 / tan(63) = 8.15 ( round as needed)
Answer: volume = 309.4 cubic meter
Step-by-step explanation:
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
Where
h represents the height of the cylinder.
r represents the radius of the cylinder.
π is a constant whose value is 3.14
From the information given
Height = 2.1 meters
Diameter of circular base = 13.7 meters.
Radius = diameter/2 = 13.7/2 = 6.85
Therefore,
Volume = 3.14 × 6.85² × 2.1 =
309.4 cubic meter to the nearest tenth
