Answer:

The volume (density) of cement that will be needed to cover this hollow pipe is:

= 50,000 kg/m³

Step-by-step explanation:

Length of a cylindrical pipe = 5m

Width of the cylindrical pipe = 4m

Depth of the cylindrical pipe = 2.5m

The cubic meters of the cylindrical pipe = 5 * 4 * 2.5 = 50m³

1 cubic meter is equal to 1,000 kilogram

Therefore, the volume (density) of cement that will be needed to cover this hollow pipe is:

= 50 * 1,000

= 50,000 kg/m³

Jerry has just purchased his first home for $190,000. He put down a 20 percent down payment of $38,000 and took out a 5 percent
shepuryov [24]

Answer:

$66.67

Step-by-step explanation:

The calculation of first monthly mortgage payment is amortization is given below:-

Amount borrowed = Purchase first home cost - Down payment

= $190,000 - $38,000

= $152,000

Annual interest = ($152,000 × 5%) ÷ 12

= $7,600 ÷ 12

= $633.33 per month

Now,

First monthly payment = Mortgage payment - Annual interest

= $700 - $633.33

= $66.67

Hence, we simply applied the above formula.
