(x + -5) • -2 > 4 What is/are the number/s that x can be?

Scrat [10]

Answer:

x < 3

Step-by-step explanation:

Step 1 :

Equation at the end of step 1 :

-2 • (x - 5) - 4 > 0

Step 2 :

Step 3 :

Pulling out like terms :

3.1 Pull out like factors :

6 - 2x = -2 • (x - 3)

Equation at the end of step 3 :

-2 • (x - 3) > 0

Step 4 :

4.1 Divide both sides by -2

Remember to flip the inequality sign:

Solve Basic Inequality :

4.2 Add 3 to both sides

x < 3

Find the weight of the cast iron shape shown below at 0.26 pounds per cubic inch. (round to the nearest pound). The height of th

weqwewe [10]

Answer:

640 pounds

Step-by-step explanation:

The rest of the question is the attached figure

So, the total volume = V(cylinder ) + V(cone)

The volume of cylinder = π r² h

The volume of cone = π r² h/3

Both of the cylinder and the cone have the same diameter = 14 inches

So, the radius = 14/2 = 7 inches

The height of the cylinder is 13 inches and the height of the cone is 9 inches.

So, The volume of cylinder = π r² h = π * 7² * 13 = 2,001.2 in³

And The volume of cone = π r² h/3 = π * 7² * 9/3 = 461.8 in³

So, the total volume = 2,001.2 + 461.8 = 2,463 in³

So, the total weight = 0.26 pounds per cubic inch times the total volume

= 0.26 * 2463 = 640.38 pounds

= 640 pounds (to the nearest pound)
