In a 30-60-90 triangle, The short leg measures 45 inches. Find the EXACT perimeter of the triangle. (HINT exact means DO NOT ROUND)

If 25% of y is 30, what is 60% of y?

What is the best approximation for the area of a circle with a radius of 4 m ? use 3.14 to approximate pi

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
