Answer: 3/16
Step-by-step explanation: To multiply fractions, first multiply across the numerators and then multiply across the denominators.
×
= ?
15 × 1 = 15
20 × 4 = 80
can be reduced by dividing both the numerator and denominator by the Greatest Common Factor which is 5.
15 ÷ 5 = 3
80 ÷ 5 = 16
Therefore,
×

Answer is :
cos⁻¹[(-1-4√7)/(√17, √8) = 173.33° ≈ 173°
Answer: A) $120,953
Step-by-step explanation:
The formula to calculate the compound amount (semi-annually):-
, where P is principal amount , r is rate of interest and n is the number of time periods.
Given : Principal amount : P= $90,000
Rate of interest : 6% per annum = 0.06 per annum
Time period : n= 5 years

Hence, the ABC will have $ 120,953 in the account after five years if interest is reinvested.
Answer:
20%
Step-by-step explanation:
In the graph, there is a cycle of increasing and decreasing. First, the original circle increases by 25% into the new, larger circle. Then, the circle does back to its original size. So, to solve we can assign a value to the smaller circle, increase it by 25%, and then find what percentage brings this back to the original value.
It is easiest to assign the value of 100 because it is easy to work with. So, let's say the smaller circle is 100; this increased by 25% is 125. The next step is to find what percentage of 125 brings us back to 100. There are multiple ways to do this such as guess and check or proportions/fractions. Either way, the correct percentage is 20%. If you decrease 125 by 20% you get the correct value of 100. This means that the missing number must be 20%.
