Answer: She invest 41500 at 7% interest and 900 at 11% interest.
Step-by-step explanation:
Formula for simple interest = 
Let 
Simple interest by first investment = 
Simple interest by second investment = 
As per given,
Total interest = $204
Hence, she invest 41500 at 7% interest and 900 at 11% interest.
Answer:
Step-by-step explanation:
Formula
Area = 1/2 (b1 + b2)*h
Givens
b1 = 11 m
b2 = 13 m
Area = 96
h = ?
Solution
96 = 1/2 (11 + 13) * h Multiply by 2 Combine the bases as well.
96*2 = (24) * h Divide by 24
96*2/24 = h Multiply by 2 and divide by 24
h = 8
Answer:
what is the question u are asking?
The first one is 52 because if you toke 80 and subtract it by28 it will give you x witch is 52 s=52
we are given the expression csc (2 pi / 3 ) and is asked to evaluate the expression. According to the trigonometric identities, the inverse of cosecant (CSC) is sine (sin) function. hence using the calculator in radians mode, sin 2pi/3 is equal to 2/sqrt 3. Taking the reciprocal of the answer, the final answer is 2 sqrt3 over 3.
