Speed = 60.8 miles per hour.
Answer:
.......
Step-by-step explanation:
Jahlan, simple interest means that interest is paid every year on the original $4000.
To find 2% of 4000, you multiply 4000(.02) = $80.
Since the interest is the same, 3(80) = $240.
Answer:
2 metre
Step-by-step explanation:
let the width around the field be x metre
then (16+2x)(10+2x)-16×10=120
160+32x+20x+4x²-160=120
4x²+52x-120=0
or x²+13x-30=0
x²+15x-2x-30=0
x(x+15)-2(x+15)=0
(x+15)(x-2)=0
either x+15=0,
x=-15 (Rejected being negative)
or x-2=0
x=2 metre
The answer is 5 7/12, here's why:
First convert the mixed numbers into improper fractions to make it simpler to deal with.
1 5/12 = 17/12
4 1/6 = 25/6
Now make them equivalent.
17/12 can stay the same,
25/6 can become 50/12
Now it's just 17/12 + 50/12
Just add the numerators!
17/12 + 50/12 = 67/12
All we have to do from here is simplify 67/12.
12 goes into 67 5 times, with a remainder of 7.
5 becomes the whole number, and our fraction is the remainder (7) over 12.
So 67/12 = 5 7/12.
This is as simplified as the answer can get.
Hope this helps!
