Answer:
b) 20
Step-by-step explanation:
Here m∠C = 90, It is a right triangle.
So we can use the Pythagorean theorem.
b = √(c^2 - a^2)
Given: a =21 and c = 29. Now let's plug in these values in the above formula, we get
b = √(29)^2 - (21)^2
b = √(841 - 441)
b = √400
b = 20
Therefore, the side length b = 20.
Hope this will helpful.
Thank you.
Answer:
Step-by-step explanation:
The total resistance of two resistors wired in series is the sum of the two individual resistances: 33 ohms + 47 ohms = 80 ohms.
This is
(6(3)^-1 (-5)^0)^-3
= (6/3 * 1)^-3
= (2)^-3
= 1/8 Answer
Given:
Principal = $1290
Rate of simple interest = 4%
Time = 9 months
To find:
The interest and total saving in the account altogether.
Solution:
The formula for simple interest is
...(i)
where, P is principal, r is rate of interest and t is time in years.
We know that,




Putting P=1290, r=4 and t=0.75 in (i), we get



So, the simple interest is $38.70.
Total savings is

Therefore, the total amount in the account altogether is $1328.70.
