Answer: the hourly cost of renting a power washer is $5
the hourly cost of renting a generator is $10
Step-by-step explanation:
Let x represent the hourly cost of renting a power washer.
Let y represent the hourly cost of renting a generator.
On his first job, he used each piece of equipment for 6 hours which cost $90. This means that
6x + 6y = 90 - - - - - - - - 1
On his second job, he used the power washer for 4 hours and the generator for 8 which cost $100. This means that
4x + 8y = 100 - - - - - - - - - - 2
Multiplying equation 1 by 4 and equation 2 by 6, it becomes
24x + 24y = 360
24x + 48y = 600
Subtracting, it becomes
- 24y = - 240
y = - 240/-24 = 10
Substituting y = 10 into equation 1, it becomes
6x + 6 × 10 = 90
6x + 60 = 90
6x = 90 - 60 = 30
x = 30/6 = 5
The percent uncertainty in the volume of a spherical beach
ball whose radius is r = 5.94 +- 0.04 is about +- 0.00027 cubic units. This was
solve using the formula of a volume, V = (4/3)piR^3 where R is the uncertainty

The word problem is based on division ratio so u have to divide by five so 100 divided by five is 20 meaning the collector has to sell 20 band posters.
To answer this question, you need to find the area of the divided land that the farmer want. Since it was a square with 1/4 mile length then the area would be:
1/4 mile * 1/4 mile= 1/16 miles square.
Then you can divide the total area of land the farmer buys, with the area of divided land. The calculation would be: (1/2 square miles) / (1/16 square miles)= 16/2=8 pieces of field
Answer:
I would buy the 2000 Toyota Tundra. Yes it is the most expensive, but it is the newest so it should require less expense money for problems, it is a manual transmission 6 cylinder so it should get better gas mileage, and it has fewer miles. The rankings of these trucks are not provided, however a Toyota tundra is considered to be a workhorse in the truck. If this is an opinion question, that's my choice.
