I'll use arithmetic series to find it.
First two-digit number divisible by 3 is 12, last such number is 99. Every 3rd number is divisible by 3.
So,
<u>There are 30 such numbers.</u>
Yes because if you graph it, it will pass the vertical line test
C.) 5, Using P.E.M.D.A.S you have to multiply first, so replacing the variable X with 5, it should look like this: (6*5) -3=27. 6*5 is 30, 30 subtracted by 3 is 27.
Answer: 65000$ worth of things
This is edited, because I got it backwards last time.
We need to make 2500, but she only makes 4% of whatever she sells.
That means the equation is
2500 = 0.04x
Now, we just need to divide both sides by 0.04 and we get 65000.
Sorry for the confusion.
Answer:
1/5, 1/6, 1/7, 1/8
Step-by-step explanation:
The formula for the sequence is (n+3)!/ (n+4)!
The first terms uses n=1
a1 = (1+3)!/ (1+4)! = 4!/5! = (4*3*2*1)/(5*4*3*2*1) = 1/5
The first terms uses n=2
a2 = (2+3)!/ (2+4)! = 5!/6! = (5*4*3*2*1)/(6*5*4*3*2*1) = 1/6
The first terms uses n=3
a3 = (3+3)!/ (3+4)! = 6!/7! = (6*5*4*3*2*1)/(7*6*5*4*3*2*1) = 1/7
The first terms uses n=4
a4 = (4+3)!/ (4+4)! = 7!/8! = (7*6*5*4*3*2*1)/(8*7*6*5*4*3*2*1) = 1/8
