Answer:
B is the correct answer :))
because she's doing the math so that there are 40 plants in each row. So, she's trying to figure out how many rows she will need. When she does the math for 40 plants in each row, she ends up with 193 rows, and 25 corn plants left over
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
when there are exponents with same bases multiplied by each other, keep the base and add the exponents
4^(3)+4^(5)=4^8
4^8 is D in this question

Answer:
<em>The voltage at the middle source is</em> 
Step-by-step explanation:
<u>Voltage Sources in Series</u>
When two or more voltage sources are connected in series, the total voltage is the sum of the individual voltages of each source.
The figure shown has three voltage sources of values:
The sum of these voltages is:
Operating:
We know the total voltage is 
, thus:
Equating the real parts and the imaginary parts independently:
4+a=6
1+b=-3
Solving each equation:
a = 2
b = -4
The voltage at the middle source is
To solve, first let’s define regrouping:<span>
<span>=> Regrouping involves carrying and borrowing during subtraction and addition of the given numbers.
So let us have the non-regrouping decimal number:
=> 8.4
Next, the other regrouping decimal
=> 5.7
So now let us show how it becomes 14.1:
8.4
+5.7
14.1
Starting from the right, 4 + 7 is equal 11, so bring down 1 and carry 1. Now 8+5 = 13, but 13 + carry 1 = 14
<span>Thus, the answer is 14.1</span></span></span>
