Answer:
The total interest earned at the end of the year was $ 820, and the interest generated by the total deposited was 10.25%.
Step-by-step explanation:
Given that last year, Manuel deposited $ 7000 into an account that paid 11% interest per year and $ 1000 into an account that paid 5% interest per year, and no withdrawals were made from the accounts, to determine what was the total interest earned at the end of year and what was the percent interest for the total deposited, the following calculations must be performed:
7000 x 0.11 + 1000 x 0.05 = X
770 + 50 = X
820 = X
8000 = 100
820 = X
820 x 100/8000 = X
82,000 / 8,000 = X
10.25 = X
Therefore, the total interest earned at the end of the year was $ 820, and the interest generated by the total deposited was 10.25%.
The answer is no because the problem has no solution. Hope this helps
<h2>
Answer:</h2>
The values of sinθ and tanθ are:
and
<h2>
Step-by-step explanation:</h2>
It is given that:
where
i.e. the angle θ lie in the second quadrant.
Also, we know that in the second quadrant sine and cosecant function is positive.
whereas cosine,secant, tangent and cotangent functions are negative.
Now, we know that:
i.e. here
Hence, we have:
Also,
Now, on rationalizing we have:
Since these are similar triangles you can use any two corresponding sides to figure out the scale factor.
Use the bottom side. Going from the first triangle to the second the scale factor is:
15/9 = 5/3
