Answer:
3.2%
Step-by-step explanation:
The computation of the annual rate of interest is shown below:
As we know that
Simple interest = Principal × rate of interest × time period
($1,857.60 - $1,800) = $1,800 × rate of interest × 1
$57.60 = $1,800 × rate of interest × 1
So, the rate of interest is
= $57.60 ÷ $1,800 × 100
= 3.2%
Hence, the rate of interest on annual basis is 3.2%

Answer:
64= 39+x
Step-by-step explanation:
x represents the unknown or in this case the money made to get to 64
39 is what she started with and 64 is the final total
Answer: X=14
Step-by-step explanation:
An angle of depression is the angle of a slant to the upper horizontal line. The official definition is: <span>the </span>angle<span> formed by the line of sight and the horizontal plane for an object below the horizontal.
Thus, for this problem, we must use trigonometry. The tower is perpendicular to the upper horizontal and the ground, so after we draw a line connecting the points we get 90 - 63 = 27, which is one of the angles in the right triangle.
The other angles are ninety and 63. We wish to find the measure of the bottom of the triangle, so we use tangent which includes both legs.
Therefore, tan(27)=x/43. Plugging this into a calculator, we get roughly 21.9.
Hope this helped! It probably sounds a lot harder than it actually is without a picture.</span>
