First, you calculate 10% of 2500, which is 250. Then, you multiple it by five because she borrowed it for FIVE years. The answer is C. :)
Answer:
16.67%
Step-by-step explanation:
9:54*100 =
( 9*100):54 =
900:54 = 16.67
Point slope form is the line through (a,b) with slope m is
y - b = m(x - a)
y - 8 = 5(x - 9)
y - 8 = 5x - 45
y = 5x - 37
Answer: y = 5x - 37
Take into account the length of the right side of the figure is 10. Moreover, x is the hypotenuse of a right triangle. To find the value of x, use the sine function:
cos 45 = opposite side/hypotenuse
cos 45 = 10/x solve for x
x = 10/cos 45
x = 10/0.707
x = 14.14
with the previous value of x, you can find y. Again, consider the right triangle right side. x is the hypotenuse. Use the Pythagorean theorem to find y:
x² = 10² + y² solve for y and replace x
y² = x² - 10²
y² = (14.14)² - 100
y² = 200 - 100
y² = 100 apply square root both sides
y = 10
Hence, the values of x and y are 14.14 and 10 respectively
