Estimate a 15% tip on a dinner bill of $38.65 by first rounding the bill amount to the nearest ten dollars.

$5.81

Step-by-step explanation:

First, we round off the dinner bill of $38.65 to the nearest ten dollars, since 0.65 is greater than 0.5 benchmark for approximation, we round up. Therefore, 38.65 to the nearest tenth means we remove the last digit of the decimal= $38.7

15% tip on a dinner bill of $38.7 =

15/100 × 38.7

0.15 x 38.7= $5.805

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²

apex answer is: true.
