Step-by-step explanation:
<h3>
The complete exercise is: "Dan spends 
of his wages on rent and 
on food. if he makes £396 per week, how much money does he have left?"</h3>
Let be "x" the amount of money Dan has left.
You know that he spends on rent. You calcualte this amount of money by multiplying £396 by . Then:
In order to find the amount of money he spent on foord, you must multiple £396 by . Then:
Therefore, the amount of money Dan has left is:
A) A = 20,000 [Principle] * (0.05 [Interest] * 4 [Number of years]) = $4,000 interest
b) A = 20,000 [Principle] * (0.05 [Interest] * 2 [Number of years]) = $2,000 interest
It would be a 90%. In the calculator 18 is what percent of 20.
Answer:
3,4,5 forms a right triangle
1,2 ,9 does not form a triangle
Step-by-step explanation:
Three side lengths that will form a triangle
3,4,5
This is a Pythagorean triple. It forms a right triangle
3^2 +4^2 = 5^2
9+16=25
25=25
Three side lengths that will not form a triangle
1,2 9
The sum of the two smaller sides must be greater then the third
1+2 < 9 not greater
