Subtract 32 to both sides to the equation becomes -5x^2 + 7x + 9 = 0.
To solve this equation, we can use the quadratic formula. The quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -7 ± √(7^2 - 4(-5)(9)) ] / ( 2(-5) )
x = [ -7 ± √(49 - (-180) ) ] / ( -10 )
x = [ -7 ± √(229) ] / ( -10)
x = [ -7 ± sqrt(229) ] / ( -10 )
x = 7/10 ± -sqrt(229)/10
The answers are 7/10 + sqrt(229)/10 and 7/10 - sqrt(229)/10.
A gallon of that ice cream would be 10.99, so 2 1/2 would be 20.10.
Break everything into 8ths.
50% = 1/2=4/8
4/8+1/8=5/8
the remaining distance is 8/8-5/8. so 3/8, not 1/4
Arc length = (πrθ)/180 [r=radius, θ=central angle, π≈3.14]
arc length = (3.14 * 15 * 60)/180 = 3.14 * 5 = 15.7 cm
to do this you would need to shade in 7 out of the 10 rows going horizontally or vertically it doesnt really matter as long as u shade in 7 rows of them
