4) 1 mi/6min * 60 min/1h = 1/10 mi/h = 0.1 mi/h
5) 175 mi *1 h/50 mi = 3.5 h
6) Mr. Smith - 9 min -from school to the park.
Mr. McNeil walks twice as fast, that means if s is a speed of Mr. Smith,
then 2s is a speed of Mr. McNeil.
Distance from school to the park = 9*s, distance from school to the park and back = 2*9*s.
Time= Distance/Speed
For Mr. McNeil:
Time from school to the park and back= distance from school to the park and back/ speed of Mr. McNeil = 2*9*s/2s = 9 min.
Answer:
8 times
Step-by-step explanation:
3/4 n = 6
Multiply each side by 4/3 to isolate n
4/3 * 3/4 n = 6*4/3
n = 8
Answer:
x = 1.723
Step-by-step explanation:
The zeros of a function f(x) are the points where the function crosses the x-axis. At these points, the function will have a value of zero, that is;
f(x) = 0
We simply graph the function and determine the points where it crosses the x-axis. From the attachment, f(x) crosses the x-axis at;
x = 1.723
First, we need to make a function out of the table. This function will be in slope-intercept form. The function is y = 30x so in 11 minutes Machine J will make 330 candies. In 11 minutes Machine K will make 286. subtract 286 from 330 to get 44. Machine J will make 44 more candies than machine K in 11 minutes.
