Answer:
You just need to multiply everything in the correct square
Answer:
the amount borrowed is ≅ $527
Step-by-step explanation:
Given that;
simple interest rate r = 180% p.a
Let the amount borrowed (principal) be $x.
time t = 4 weeks = 28 days
= 28/365 year
= 0.0767 year
we all know that :
![Simple \ \ interest = \dfrac{P*r*t}{100}](https://tex.z-dn.net/?f=Simple%20%5C%20%5C%20%20interest%20%3D%20%5Cdfrac%7BP%2Ar%2At%7D%7B100%7D)
![Simple \ \ interest = \dfrac{x*180*0.0767}{100}](https://tex.z-dn.net/?f=Simple%20%5C%20%5C%20%20interest%20%3D%20%5Cdfrac%7Bx%2A180%2A0.0767%7D%7B100%7D)
Simple interest = 0.13806x
Total amount to be paid after 4 weeks= Interest+Principal
= x + 0.13806x
= 1.13806x
Thus;
1.13806x = $600
x = $600/ 1.13806
x = $527.21
Hence; the amount borrowed is ≅ $527
The answer would be add 13 because
12 + 13 would be 25, 25 + 13 would be 38. Hope this helps
Answer:
d) 3
Step-by-step explanation:
7x+4=25
7x=21
X=3
The value of cos(A+B) is 36/325.
<h3>What is Trigonometry?</h3>
The branch of mathematics concerned with specific functions of angles and their application to calculations.
Given:
cos(A)=−5/13
sin(B)=7/25
Now Using identity,
sin²A + cos² A= 1
sin A= √1 - cos² A
sin A = √1- 25/169
sin A= √144/169
sin A= 12/13
Again,
sin²B + cos² B= 1
cos B= √1 - sin² B
cos B = √1- 49/625
cos B= √576/625
cos B= -24/25
Now,
cos (A +B) = cos A cos B - sin A sin B.
= -5/13* (-24/25) - 12/13* 7/25
= 120/325 - 84/325
= 36/325
Hence, the value of cos (A + B) is 36/325.
