It’s BD because it need to be the opposite ray and this one is the opposite ray so yes this is it
X = - 1/2
In other way is x = -0.2 , x = -5^-1
Answer: 461.60 is the volume of liquid the tank can hold.
Step-by-step explanation:
We were given;
Height H = 9 ft
Diameter D = 14 ft
Pie π = 3.14
We will make use the formula of volume of a cone to get volume of water the tank can hold because it is said that the tank is in the shape of a cone
So
V = 1/3 * πr2h
First we need to find our radius r
Radius = 1/2 of diameter = 14/2 = 7
So using the formula
V = 1/3 * πr2h
V = 1/3 (3.14 * 7² * 9)
V = (3.14 * 49 * 9)/3
V = 1384.74 / 3
V = 461.58 = 461.60 (nearest ten)
y = -x + 1/3
+ x + x
--------------------------
x + y = 1/3
2 and 3 are both parallel because both slopes are m=3/5, which equal slopes-parallel lines
