Let the width of the field be represented by x.
since the length is two times as long as the width, the length of the field is 2x.
perimeter of field = 6x = 300 feet
x = 50 feet
hence, width,x = 50 feet
length, 2x = 100 feet
Answer:
The simple interest for 4 months = Rs 240
Step-by-step explanation:
formula:-
simple interest I = [PNR]/100
P - Principle amount
N - Number of years
R - Rate of interest
It is given that, $7,800 at 9.25% for 4 months
<u>To find the simple interest for 1 year</u>
I = [PNR]/100
I = [7800*1*9.25]/100 = 721.5
<u>To find the simple interest for 4 months</u>
4 months = (1 year )/3
4 months interest = 721.5/3 =240.5 ≈ 240
Therefore the simple interest for 4 months = Rs 240
<h2><u>Part A:</u></h2>
Let's denote no of seats in first row with r1 , second row with r2.....and so on.
r1=5
Since next row will have 10 additional row each time when we move to next row,
So,
r2=5+10=15
r3=15+10=25
<u>Using the terms r1,r2 and r3 , we can find explicit formula</u>
r1=5=5+0=5+0×10=5+(1-1)×10
r2=15=5+10=5+(2-1)×10
r3=25=5+20=5+(3-1)×10
<u>So for nth row,</u>
rn=5+(n-1)×10
Since 5=r1 and 10=common difference (d)
rn=r1+(n-1)d
Since 'a' is a convention term for 1st term,
<h3>
<u>⇒</u><u>rn=a+(n-1)d</u></h3>
which is an explicit formula to find no of seats in any given row.
<h2><u>Part B:</u></h2>
Using above explicit formula, we can calculate no of seats in 7th row,
r7=5+(7-1)×10
r7=5+(7-1)×10 =5+6×10
r7=5+(7-1)×10 =5+6×10 =65
which is the no of seats in 7th row.

Actually, it is 40 mph. Unless you mean he goes to the store in half an hour and back in another half. Just clarify the wording.
