3 1/8 + 1 2/5 = 4 21/40 because the least common denominator is 40. So 5x8=40 and 2x8=16. Then 8x5=40 and 1x5=5. Next you add the numerators and get 21/40. And last but not least you add the whole numbers to get a final answer of 4 21/40
The compound interest is given by:
A=p(1+r/100)^n
where;
A=amount
p=principle
r=rate
n=time
therefore the time taken for Felicia's money to double will be:
350=175(1+4/100)^n
350/175=1.04^n
2=1.04^n
therefore introducing natural longs we get:
ln2=nln1.04
n=(ln2)/(ln1.04)
n=17.7 years
The answer is 17.7 years
160,000 is the longest bridge in China and 70,000 long bridge in china
Solution:
<u>We know that:</u>
- The base angles are equivalent.
<u>This means that:</u>
- This triangle is an isosceles triangle.
- The legs of the triangle are equivalent.
<em>Let's use Pythagoras theorem to find z.</em>
<u>Finding z using Pythagoras theorem.</u>
Thus, the value of z is 8.
