Answer:
The volume of the tank is 1235ft³
Step-by-step explanation:
To calculate the volume of a cylinder we have to use the following formula:
v = volume
h = height = 13ft
π = 3.14
r = radius = 5.5ft
v = (π * r²) * h
we replace the unknowns with the values we know
v = (3.14 * (5.5ft)²) * 13ft
v = (3.14 * 30.25ft²) * 13ft
v = 94.985ft² * 13ft
v = 1234.805ft³
Round to the nearest whole number
v = 1234.805ft³ = v = 1235ft³
Answer:
12a - 6b
Step-by-step explanation:
Given
8a + 3b + 4a - 9b ← collect like terms
= (8a + 4b) + (3b - 9b)
= 12a + (- 6b)
= 12a - 6b

Answer:
1: x=y-3 linear equation : y=x+3
2:y=-2x-3 linear equation : y=-2x-3
3: -4y+6 =2 linear equation : y=2-6/-4 ⇒ y=1
4:2/3 x-1/3y=2 , linear equation : y=2x-6
-1/3 y=2-2/3 x
y=-6+2x
13: 5x+25=y² not linear
y = √5x+25
14 : 8+y=4x linear y=4x-8
15: 9xy-6x=7 not linear
16: 4y²+9=-4 ⇒ y²=-4/4 -9/4 ⇒y=√-1-2.25 ⇒y=√-3.25 not linear
17: 12x=7y-10y linear : y=12x/-3 ⇒ y=-4x
18:y=4x+x linear y=5x
