Based on the prices of the six grocery items if their prices are rounded off to the nearest dollar, the estimated total cost of the grocery items is  $42

<h3>What is the estimated total cost?</h3>

First, round off the costs to the nearest dollar:

$0.27 = $1.00

$12.36 ⇒ $12.00

$6.35 ⇒ $6.00

$2.59 ⇒ $3.00

$9.71 ⇒ $10.00

$9.54 ⇒ $10.00

The estimated cost is therefore:

= 1 + 12 + 6 + 3 + 10 + 10

= $42

If your front lawn is 17.0 feet wide and 20.0 feet long, and each square foot of lawn accumulates 1050 new snowflakes every minu
Alexus [3.1K]

Answer: 42.84 kg

Step-by-step explanation: Lawn is 17 ft x 20 ft.

Its area is S = 17 x 20 = 340 ft²

Each ft² of lawn accumulates 1050 snowflakes/min, 1ft² = 1050 s.f./min.

As 1 hour has 60 min, the lawn accumulates 63000/hour →

1050 x 60 = 63000

1ft² = 63000s.f./hour

This way, 340 ft² of lawn will accumulate 21,420,000 s.f/hour →

340 x 63000 = 21420000

As 1 snowflake has 2mg,  21,420,000 will have 42,840,000 mg.

As 1kg = 1,000,000 mg

42,840,000/1,000,000 = 42.84 kg
