Answer:

$94.24

Step-by-step explanation:

Given :

Diameter of circular slab = 18feet

Thickness of slab = 3 inches ; inches to ft = 3 /12 = 0.25 feets

Volume of slab = πd²t/4 = (π*18²*0.25) / 4 = 63.6 ft³

1 cubic yard = 27 feet

Volume in yard = 63.6 / 27 = 2.356 yd³

Concrete = $40 per yd³

Cost = $40 * 2.356 = $94.24

\\\\\\
g(x)=-(x+3)^2+1\impliedby f(x)\qquad \qquad f(-1.5)=-[(-1.5)+3]^2+1

and surely you know how much that is.

What is the value of x ?
Setler79 [48]

Answer:

19

Step-by-step explanation:

When you have a straight line with a transversal, the two angles are equal to 180 degrees

180=123+3x ---> subtract 123 to the other side

57=3x ---> divide by 3

x=57/3

x=19

Solve 16x + 8 > 12x+ 20.
MrRa [10]

Answer:

x > 3

Step-by-step explanation:

16x + 8 > 12x + 20 <== subtract 12x from both sides

- 12x      - 12x

4x + 8 > 20 <== subtract 8 from both sides

    - 8     - 8

4x > 12 <== divide both sides by 4

/4     /4

x > 3

This means that x is any value that is greater (bigger) than 3.

Hope this helps!
