1) count and mark so that you will have 50 blocks to work with. Shade 19 of those blocks. This will represent your fraction. To get the % divide 19/50= 0.38 move the decimal to the right two places and you will have 38%.

2) do the same count and mark off 20 blocks and shade 13. This represents the fraction. Divide 13/20 = 0.65. Move the decimal two places to the right and you will have 65%.

Answer:

$3 \: s$

Step-by-step explanation:

$y = - 16 {x}^{2} + 32x + 48 \\ 0 = \frac{ - 16 {x}^{2} + 32x + 48 }{ - 16} \\0 = {x}^{2} - 2x - 3 \\ 0= {x}^{2} - 3x + x - 3 \\ 0= x(x - 3) + 1(x - 3) \\0 = (x + 1)(x - 3) \\ \\ x + 1 = 0 \\ x = - 1 \\ x - 3 = 0 \\ x = 3$
