A dolphin swims 665,280 feet in 3 hours. Use the formula dart, where d represents distance, r represents rate, and t represents
barxatty [35]

Step-by-step explanation:

a) r=d/t ( same as formula of speed)

b) r= 665280/3=221760 feet/hr

c) distance in miles = 665280/5280= 126

so r=126/3 = 42 miles/hr

d) i think using miles makes more sense cz using feet will result in greater number of values so there is a greater chance of human error

Which one is larger and why 12 x 3/7 or 6 x 3/7
Serggg [28]

Answer:12 x 3/7 is larger than 6 x 3/7.

12x3/7=36/7 while 6x3/7=18/7 since both fractions 36/7 and 18/7 have the same denominators, to know which is larger we just check the numerator,the fraction with the largest numerator is largest which is 36/7

Step-by-step explanation:

12x3/7=(12x3)/7=36/7

6x3/7=(6x3)/7=18/7

36/7 is larger than 18/7

Write the linear equation given two points (-6, 8) and (3, -7). *
horrorfan [7]

\bf (\stackrel{x_1}{-6}~,~\stackrel{y_1}{8})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{-7}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-7}-\stackrel{y1}{8}}}{\underset{run} {\underset{x_2}{3}-\underset{x_1}{(-6)}}}\implies \cfrac{-15}{3+6}\implies \cfrac{-15}{9}\implies -\cfrac{5}{3}

\bf \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{8}=\stackrel{m}{-\cfrac{5}{3}}[x-\stackrel{x_1}{(-6)}]\implies y-8=-\cfrac{5}{3}(x+6) \\\\\\ y-8=-\cfrac{5}{3}x-10\implies y = -\cfrac{5}{3}x-2

Your friend says that 14.5% is equivilent to 14.5
SCORPION-xisa [38]
14.5% = 0.145 = 145/1000

14.5 = 14500/1000

<span>So 14.5% is a hundredth the size of 14.5, so they are not equal and the friend is incorrect.</span>
