Answer:
C
Step-by-step explanation:
Sine = opposite / hypotenuse
If we think of the hypotenuse =1, then sine(C) = x / 1 or just "x"
The sine (A) = adjacent / hypotenuse = y / 1 or just "y"
Answer:
21
Step-by-step explanation:
8 * 2 = 16
5 * 2 = 10
68 - 16 = 52 - 10 = 42.
The perimeter of the square is 42.
42 / 4 = 10.5. 10.5 is the length of a side.
10.5 * 2 = 21.
Well this is easier to look at when you turn them into decimals.
3/4 = 0.75
and..
4/5 = 0.8
0.8 is bigger than 0.75
So this means..
4/5 is bigger!!
Good Luck! :)
Answer:
At a rate of 5%.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
In this question:
Payment plan for $1500 means that 
$450 interest after 6 years means that 
We have to find the rate I. So




At a rate of 5%.
