Answer:
If the pitch is 1/3, the slope is <em>8:12</em>.
Step-by-step explanation:
Remember, slope is expressed as a ratio and in inches per foot. And pitch is a fraction derived by dividing the rise by the entire span.
Answer:
amplitude = 4
Step-by-step explanation:
the amplitude is the maximum subtract the minimum divided by 2
maximum = 1 and minimum = - 7
amplitude = 
= 
= 4
80
Step-by-step explanation:
5×6 = 30 and 30×8 = 240 divide that by three you get 80
Answer:
Step-by-step explanation:
1.
d - 27 = 45
add 27
d = 72
2.
h - 114 = 28
add 114
h = 142
3.
-4 + x = 15
add 4
x = 19
4.
-39 + g = 72
add 39
g = 111
If we set the unknown distance (in miles) as x, then we set up an equation according to the data, we can solve for x.
Time taken to go to resort : x/48
Time taken to return : x/40
Total time = x/48+x/40 = 11
Solve for x
common multiple between 48 and 40 = 240
so
5x/240 + 6x/240 = 11
(5x+6x)/240 = 11
11x = 11*240, => x=240
Distance from home to resort is 240 miles
