Answer:
It takes 27 minutes for the element to decay to 35 grams
Step-by-step explanation:
Given:
Initial amount = 790 grams
Final amount = 35 grams
Half life = 6 minutes
To find:
Time taken for the element to reduce into 35 grams = ?
Solutions
Time taken = 
On substituting the values given, Time taken
= 
= 
= 
= 26.97
= 27 minutes
Answer:
<u>The correct answer is 58.82 square meters of solar panels will be needed to supply 2 kilowatts</u>
Step-by-step explanation:
Solar cell energy supply = 34 watts per square meter
Therefore, 100 square meters will supply 3400 watts which is 3.4 kilowatts.
How many square meters of solar panels would you need to 2 kilowatts?
Total energy = 2 kilowatts = 2,000 watts
Number of square meters = Total energy/Solar cell energy supply
Number of square meters = 2,000/34
<u>Number of square meters = 58.82</u>
<u>It will be necessary 38.82 square meters of solar panels to supply 2 kilowatts</u>

Answer:
D) What is the number of gallons of water in a pool?
Step-by-step explanation:
A statistical question consists of varied responses and not just 1 specific answer. For example, the first 3 questions only have 1 specific answer each, while the last question can vary depending on the size of the pool.
Answer:
B.
Step-by-step explanation:
The graph that is going to show the function, has two parts: one for numbers equal or less than 3 and the other for numbers greater than 3
Then, for x≤3, the function is f(x) = 4. This is a constant so the graph is a horizontal line.
Additionally, for x>3, the function is f(x)=12x. This is a straight line with a positive slope.
So, the answer that follows these 2 conditions is B.
