42:125, 42/125 or 42 to 125
The answer is -5(x+6y+10)
Answer:
132mm
Step-by-step explanation:
all triangles= 96
formula= bh.5=sa
work= 6 x 8 = 48 x .5 = 24 24x4=96
Square= 36
formula= bh = sa
work= 6 x 6 = 36
Adding= 36 + 96 = 132
Also can you give brainliest to all of your questions bc it really hard to get brainliest and it be really nice you can choose who i dont really care but just please do it it helps a lot
That is an arithmetic sequence of the form:
a(n)=2n-1
Now the sum of an arithmetic sequence is just the average of the first and last terms times the number of terms...
We know the first term is 1, let's find the last term...
a(1000)=2(1000)-1=1999
So the sum of that sequence is:
1000(1999+1)/2
1,000,000
4 electrons will be on the second energy level. Only 2 can go on the first energy level, and only 4 can go on the second energy level. There will be 1 electron on the 3rd energy level.
