I'm pretty sure it is C. 45 because compass and straightedge is a right angle or an acute angle and 45 is less than a right angle
Answer:
Step-by-step explanation:
c^2=a^2+b^2-2abcosC
cosC= (a^2+b^2-c^2)/(2ab)
C=arccos[(a^2+b^2-c^2)/(2ab)]
C=arccos(90^2+55^2-50^2)/(2(90)55)
C=arccos(8625)/(9900)
C=29.4 degrees
Answer:
b. interest rate per period
Step-by-step explanation:
We know that
Annual interest rate is APR or (r)
Po is initial amount
n is number of periods
t is time in years
A is the amount after t years
so,
i is the interest rate per period
Hence ,
answer is
i is the interest rate per period
The first step to solve this question is to find out what 5/6 of 54000 is. So we multiply 5/6 by 54000. Why? Because there's the word "of" and "of" is usually associated in multiplication. So:
5/6 × 54000 = 45000.
So now we know that 5/6 of 54000 is 45000. So it means that she needs 45000 from senior citizens. But the question doesn't stop there, it also asks us to solve for the amount of votes she needs to win other than senior citizens.
Now we know that 45000 seniors need to vote for her we subtract 45000 to the total amount which is 54000.
54000 - 45000 is 9000.
So it means that she needs 9000 voters other than senior citizens to win the election for city council.
