Tom is painting a fence 100 feet long. He starts at the West end of the fence and paints at a rate of 5 feet per hour. After 2 hours, Huck joins Tom and begins painting from the East end of the fence at a rate of 8 feet per hour. After 2 hours of the two boys painting at the same time, Tom leaves Huck to finish the job by himself.
Answers
Answer: 26 feet
Step-by-step explanation:
They have completed 26 feet in total I don’t really understand the question because I don’t understand what I am supposed to answer so I am kinda guessing on this one. Sorry if I am wrong
Answer:
6 hours
Step-by-step explanation:
distance=rate×time (or d=rt)to determine the total length of the fence Tom paints.
d=(5)(4)
d=20 feet
Subtracting this from the total length of the fence 100 feet gives the length of the fence Tom will NOT paint: 100−20=80 feet. If Huck finishes the job, he will paint that 80 feet of the fence. Using d=rt, we can determine how long this will take Huck to do:
80=8(t)
t=10 hours.
If Huck works 10 hours and Tom works 4 hours, he works 6 more hours than Tom.
Electronic devices are made from renewable resources. True or false
Answers
Answer:
It is false.
Explanation:
Non Renewable resources are resources whose existence is limited. After consumption, they can never be regenerated or "renewed". For example, coal or oil are nonrenewable resources because we can never use them again and their amount on the Earth is limited. On the other hand, we have solar or wind energy which we can use unlimitedly again and again and we won`t reduce its amount. That is why is that called renewable.
Electric devices
-Electronic devices are components for controlling the flow of electrical currents for the purpose of information processing and system control. Prominent examples include transistors and diodes. Electronic devices are usually small and can be grouped together into packages called integrated circuits.
Renewable resources
-A renewable resource is one that can be used repeatedly and does not run out because it is naturally replaced. A renewable resource, essentially, has an endless supply such as solar energy, wind energy, and geothermal pressure.
Answer:
true
Step-by-step explanation:
Power electronics as a key element. Most renewable energy technologies only provide a certain voltage and current density (depending upon the load) to the power converter. The power converter must then adjust the voltage available from the fuel cell to a voltage high enough to operate the load.
An average fly has a mass of 0.048 grams. An average ant has a mass of 3.12 x 10^-3grams
Would 3.99 million flies or 47,000.000 ants have a greater mass?
Approxmately how much greater, in grams, would the greater mass be? Justity your answers Respond in the space provided
Answers
Answer:
the flies have a greater mass
Step-by-step explanation:
First, we should solve 10^-3 = 0.001 "for the ants" it is NOT negative now 0.001 times 3.12=0.00312 to find the total fly mass we should just multiply 0.048 times 3990000=191520 and for the ants 0.00312 times 47million=146640 so now the answer would be that the flies has a greater mass
Answer:
the flight have greater mass

Sal built a card table with a top area of 900 square inches. What is the length, in inches, of one side of the table?
Answers
30
Explanation:
It’s pretty simple actually, you just need to get the square root of 900 by seeing what two equal numbers give you 900. The answer in this scenario would be 30 since 30x30 would give you 900. Since it is a square all sides are equal and your answer would only be 30.
Hope this helped you :)
Answer: 30 inches is the length of the sides.
Step-by-step explanation: Card tables are square. So you can take √900 = 30

Which equation represents a proportional relationship?
1. y = 7x – 3
2. y = 150x
3. y = 21/x
4. y = 2x + 1
Answers
Equation 2. [tex]y = 150x[/tex] represents a proportional relationship.
Here [tex]y=150x[/tex]
On rearranging we get, [tex]\frac{y}{x} =150[/tex]
Or, [tex]\frac{x}{y} =\frac{1}{150}[/tex]
Or, [tex]x:y=1:150[/tex]
from above expression we can say now equation 2 represents a proportional relationship and the other equations cannot show the proportional relationship.
Hence Equation 2. [tex]y = 150x[/tex] represents a proportional relationship.
