Answer:
It includes it because with out it there will be no center and it wouldn't be right. And with out it ever equation wont be proportional
Step-by-step explanation:
I really hope this helps Im just saying what I think is the answer it is my fault if you get the answer wrong <3
Answer:
280000lb
Step-by-step explanation:
In this question, we shall be calculating the amount of carbon iv oxide prevented from entering the atmosphere.
Generally we know that 1kwh produces 1.37 lbs of Carbon iv oxide in the atmosphere
Now, using a 100 watt light bulb daily for 8 hours, for a year, the amount of Carbon iv oxide produced will be;
100 * 1.37 * 8 * 365 = 40040 lb
Using a 30 watt CFL for 8hrs/ day for a year, we have;
30 * 1.37 * 8 * 365 = 120012 lb
Now calculating the amount of CO2 prevented, we have 40040 - 120012 = 280028 lb = 280000 after rounding up
Okay, we can use the functions in parts 3 and 4 since we want to calculate how many points will be deducted for 3 falls and how many points are earned for 4 seconds on the rail trick.
Part 3 function:
He fell 3 times, so plug this in for 'x':
Multiply:
So he will receive a 4.8 point deduction for falling 3 times.
Part 4 function:
Where 'x' is the seconds he does the trick. He did it for 4 seconds, so let's plug that in for 'x':
Multiply:
Add:
So he will receive 38 points for the 4-second rail trick.
Answer:
16 square feet
Step-by-step explanation:
First, let's find how long each side of the cube is.
The volume of a cube is found by this formula, where s is a side of the cube:
We can take the cube root of both sides:
Just flipping it:
We know our volume is 64 cubic feet. Let's put that into our equation as V:
The cubic root of 64 is 4, since 4 * 4 * 4 = 64
Thus, each side of our cube is 4 feet.
Now, the area of a side of our cube is found using this formula:
Since we know s, we can easily find the area A by squaring it:
Answer: 16 square feet
Answer:
3
Step-by-step explanation:
Basically we need to find out whats the remainder of 1425 when you divide by 9.
1425/9 = 158 R3
R3 is 3 marbles left, so the answer is 3.
