Answer:
$420
Step-by-step explanation:
The formula for simple interest is i = prt, where p is the principal, r is the annual interest rate expressed as a decimal fraction, and t is the number of years.
Here p = $2,000, r = 0.07 and t = 3 yr, and so
i = ($2,000)(0.07)(3) = $420 was the amount of interest earned.
Answer: x=-4
Step-by-step explanation:
Since the lines are parallel they have the same angle so you can set them equal to each other.
x+54=50
x=50-54
x=-4
The longest side of a triangle is always opposite the largest angle of a triangle.
If the smallest angle of the triangle is 20 degrees, then the shortest side is opposite to it. Using this information, we can form the equality
20/100(longest leg/biggest angle) = x/20(shortest leg/smallest angle)
We can cross multiply this to get 400 = 100x. From here it is a simple "find x" and the shortest side is 4 feet.
Answer:
42 meters
Step-by-step explanation:
As ΔONM ≅ ΔXYW therefore, YW=NM=42
The correct answer is the total area of all the surfaces.
A solid is a three-dimensional shape. These shapes will have multiple surfaces or curved surfaces. To find the surface area, you would need to find the area of all the surfaces.
