Answer:
29
Step-by-step explanation:
30 - (2 - 4) ÷ (-2)
= 30 - (-2) ÷ (-2)
= 30 - 1
= 29
We're comparing 8.76 x 10^6 and 8.76 x 10^2
When multiplying numbers with same base but different powers, the result is that base and the powers added together.
Therefore:
8.76 x 10^6 can be written as: 8.76 x 10^2 x 10^4
Now, comparing the two numbers, we will find that 8.76 x 10^6 is 10^4 times greater than 8.76 x 10^2
P = potato C = corn
3P + 4C = $40
5P + 2C = $34
Multiply -2 to the 2nd equation to get
-10P - 4C = -68
Add it to the 1st equation
3P + 4C = 40
-10P - 4C = -68
-----------------------
-7P = -28
Solve for P
P = $4
Substitute 4 into P(potato) to find what C(corn) is
Answer: First Option : Sₙ= n/2(a₁ + aₙ)
Step-by-step explanation:
The nth partial sum of an arithmetic sequence or the sum of the first n terms of the arithmetic series can be defined as the sum of a finite number of term in an arithmetic sequence.
It is calculated using the formula:
Sₙ= n/2(a₁ + aₙ)
Where :
a₁ = First term
aₙ = last term
n = number of terms
