Answer:
3.93 per hour
Step-by-step explanation:
The first 4 hours is at 20 hours / 4 hours or 5 dollars an hours
The second line has a slope of 2.50 dollars an hour
But there is also a surcharge when you go over 4 hours
That is a 5 dollar flat rate at 4 hours
Assuming that we do not include the flat rate in the hourly calculation
4 hours * 5 dollar + 3 hours * 2.50 = 20+7.50
27.50 is the hourly charge
Divide by 7 hours
3.928571429
3.93 per hour
$3.50 per pound bc if you divide 7.70 by 2 1/5 that's what you get. You can double check my multiplying 3.50 by 2 1/5
Answer:
2 bags
Step-by-step explanation:
area of the yard= 35*55= 1925 ft²
1 bag covers 1240 ft²,
required number:
1925/1240= 1.55 ≈ 2 bags
so 2 bags needed to cover the area of the yard fully
The diameter is 30 cm, therefore the radius is 15 cm. The circumference of the tire is found by using the formula C = 2πr. C ≈ 2(3.14)(15) ≈ 94.2 cm. 5 km = 500,000 cm (5 x 1000 x 100). 500,000 ÷ 94.2 ≈ 5307.86 or about 5300 times (revolutions). (using π, instead of 3.14, I got 5305.16 revolutions)
