1. Natasha invests £250 in a building society account. At the end of the year her account is
credited with 2% interest. How much interest had her £250 earned in the year?
Solution: Interest = 2% of £250
= 2/100 x £250
answer = £5
2. Alan invests £140 in an account that pays r% interest. After the first year he receives £4.20 interest. What is the value of r, the rate of interest?
r/100 x £140 = £4.20
r = 100 x 4.20 / 140
= 420/140
= 3%
So the interest rate is 3%
Answer:
B
Step-by-step explanation:
its hard to explain, but just trust me bro. lol.
The slope is 3. Hope that helped!
Elemantary school so
area=legnth times width
to get greatest area, make legnth as close to width as possible in measure
to get least area, make legnth as far away from width as possible in measure
perimiter=2 times legnth+2 times width=2 times (legnth+width)
18=2 times (legnth+width)
divide 2
9=legnth+width
find closest and farthest
1+9 is farthest
4+5 is closest
areas=legnth times with
1 times 9=9
4 times 5=20
differnce is subtract
20-9=11
answe is 11
(note I didn't use decimals since the user is supposedly in elemenatry school)
