60%; Since 1/5 is .2 or 20% and then multiply that by 3.
Answer:
3.14
Step-by-step explanation:
A=π*r^2
3.14*(2^2)
3.14*4
12.56/4 (because it's 1/4th a circle)
3.14.
The square root is between 187 and 188
A= 20x25 so the area is 500
To find the perimeter you have to add both the width and length x2 so it’s 20+25 =45
45x2=90
Answer: B
Begin by simplifying the given equation, so it's rearranged into standard form. Move all the terms onto one side, so they equal 0. This would result with
-3x-9=0. Quadratic formula is (-b±√(b²-4ac))/(2a). Standard form follow this variable format:
+bx+c. Use the numbers that correspond with each variable to substitute them into the quadratic formula. This would be
(-(-3)±√(-3²-4(4)(-9)/2(4).
