Answer:
1 and 3 are the only ones that have one solution. basically, when dealing with system of equations there can be one of three answers- one solution, infinitely many solutions, or no solution. Using elimination or substitution to solve each system of equation will give you the answer.
Step-by-step explanation:
i hope this helps :)
The amount A that Patrik will cash is given by the compound interest formula:
A = C (1 + i)ⁿ
where:
C = initial amount of money
i = interest, written as a decimal number
n = number of periods
In our case, the interest is compoundend quarterly, but we have a time in years. Therefore, we need to transform years in quarters:
n = 15×4 = 60
Now, we can apply the formula:
A = 400·(1 + 0.035)⁶⁰
= 3151.24$
Hence, the correct answer is B) 3151.24$
Answer is 136. first we would find the area of the 2 triangles, formula is 1/2bh. which would give you 12, since there is 2 triangles would be 24. then you would find the area of the 3 rectangles around it which are 42, 35 and 35.
Triangle RTS is a right triangle and QTP is also a right triangle
look for the little square in the corners of a right triangle
The number is 825
66*100/8=825
