Answer: 3
Step-by-step explanation: the answer is 3 believe me
-3, 15, -75, 375,…
×5 ×5 ×5
aⁿ = a₁rⁿ⁻¹
aⁿ = 3(5)ⁿ⁻¹
a₅ = -1875
a₆ = 9375
a₇ = -46875
First, I solve the equation: 5^7+5^6...
I got 93750
--
The divisibility rules of 6 are:
- It must be divisible by 2
- It must be divisible by 3
So, let's check if 93750 is divisible by 2 first.
It's in even number which automatically means that it is divisible by 2.
No odd numbers are divisible by 2

Now let's check if it is divisible by 3 second.
The divisibility rules of 3 are:
- The digits added must be divisible by 3
So, 9 + 3 + 7 + 5 + 0 = 17
17 is NOT divisible by 3.

Therefore, your equation is not divisible by 6!
Answer:
is the probability that the piston chosen from Machine 1 is satisfactory and the piston chosen from Machine 2 is unsatisfactory
Step-by-step explanation:
The two events are independent of each other.
Hence the probability of choosing satisfactory piston from Machine 1 and unsatisfactory piston from Machine 2 is equal probability of choosing satisfactory piston from Machine 1 + probability of choosing unsatisfactory piston from Machine 2
Substituting the given values we get
Probability of choosing satisfactory piston from Machine 1 and unsatisfactory piston from Machine 2 =
=
=
Answer:
33.2444...
Step-by-step explanation:
The rate of charge is $22 per 90 feet, so first we need to find out how many feet the perimeter takes up. To find the perimeter, we distribute 2 to both sides will adding them. 2(20 + 38) The 2 is there since that only covers 2 out of the 4 lines of a rectangle. Now we do the math as mentioned. 2(30 + 38)
The answer to that would be 136 feet. Now to figure out the cost, we use 22 to see how many 90's can fit into 136 so we can get the rate needed, which is (1.511111..). Thats how many times 90 goes into it, and for every 90 feet, we pay $22, So now we multiply 1.51111 by 22 to get the answer. (33.244444)
