Answer:
y = 1/2x - 2
Step-by-step explanation:
use formula y = mx + c
m = gradient
c = y intercept
If y varies directly with x, means that they can be modeled by a linear equation, lets choose a line with 0 y intercept, that is:
y = mx + b
y = mx
where m is the slope of the line, now we plug in the data we have:
y = mx
20/3 = m(30)
solving for m:
m = (20/3)(1/30)
m = 20/90
m = 2/9
so the line equation, or function modeling the y and x relationship is:
y = (2/9)x
Answer:
About 90.73 meters/min.
Step-by-step explanation:
Dimensional analysis is done by multiplying the wanted unit over the current unit in equal measure, or the other way around.
First, we will convert feet to meters, using that 1 ft = .4048 m.
32ft/6.45sec * .3048m/1ft = 32/6.45sec * .3048m = 9.7536m/6.45 sec.
Second, we convert seconds to minutes, using that 60 sec = 1 min.
9.7536m/6.45sec * 60sec/1min = 9.7536*60m/6.45min ≈ 90.7311627m/min.

Answer:
Amount of peanut butter each student get = 533.34 gram (Approx.)
Step-by-step explanation:
Given:
Amount of peanut butter Mr black has = 32 kg
Total number of students = 60 students
Find:
Amount of peanut butter each student get
Computation:
Amount of peanut butter Mr black has = 32 kg
Amount of peanut butter Mr black has = 32 x 1,000 gram
Amount of peanut butter Mr black has = 32,000 gram
Amount of peanut butter each student get = Amount of peanut butter Mr black has / Total number of students
Amount of peanut butter each student get = 32,000 / 60
Amount of peanut butter each student get = 533.33
Amount of peanut butter each student get = 533.34 gram (Approx.)
