Answer:
12
Step-by-step explanation:
you can pack one pack in 20 min
there are three 20 min in one hour
multiply three times the four hours and you get 12
Answer:
Step-by-step explanation:
y-1 = (-6/5)(x+5)
Answer: 6.416%
Step-by-step explanation:
The percentage error formula is given by :-
Given : The estimated weight of a substance = 475 mg
The actual weight of the substance = 445 mg
Then,
Hence, the percentage error in the first weighing. = 6.416%
From the latter, we obtain the equation 1 radian = (180π)o . This leads us to the rule to convert radian measure to degree measure. To convert from radians to degrees, multiply the radians by 180°π radians .
Answer:
y=2x+3
Step-by-step explanation:
Hi there!
We want to write the equation of the line
We are given that the y-intercept of the line is (0,3) and that the line also goes through the point (2,7)
There are many ways to write the equation of the line, but the most common way is slope-intercept form, which is given as y=mx+b, where m is the slope and b is the y intercept
The value of b is actually the value of y in the point making point of the y intercept
In this case, that point would be 3
So the value of b in this case is 3
Substitute 3 as b into the equation:
y=mx+3
Now we need to find m
As the equation passes through the point (2,7), we can use it to help solve for the value of m
Substitute 2 as x and 7 as y into the equation:
7=2m+3
Subtract 3 from both sides
4=2m
Divide both sides by 2
m=2
Substitute 2 as m into the equation:
y=2x+3
Hope this helps!
