Answer: They will mark it up 13.5$ to 58.5$
Step-by-step explanation:
45 x .3 = 13.5
45 + 13.5 = 58.5
Answer:
y = -2/3 x + 23/3
Explanation:
The general formula of the linear equation is:
y = mx + c
where:
m is the slope
c is the y-intercept
1- getting the slope:
We are given that the line we are looking for is parallel to the line
y = -2/3 x + 3
This means that the slope of the two lines are equal. Comparing the general formula with the given line, we would find that the slope of the given line is -2/3. This means that the slope of the line we are looking for is also -2/3
The equation of the line now becomes:
y = -2/3 x + c
2- getting the value of c:
To get the value of c, we will use a point that belongs to the line (7,3), substitute in the equation and solve for c as follows:
y = -2/3 x + c
3 = (-2/3)(7) + c
3 = -14/3 + c
c = 3 + 14/3
c = 23/3
Based on the above, the equation of the line we are looking for is:
y = -2/3 x + 23/3
Hope this helps :)
We have the following equation:
D = m / V
Where,
m: mass
V: volume
D: density.
The volume of the rectangular prism is:
V = (5) * (10) * (8)
V = 400 cm ^ 3
For Lead:
m = D * V
m = (11.36) * (400)
m = 4544 grams
For Iron:
m = D * V
m = (7.87) * (400)
m = 3148 grams
The difference of the masses is:
4544 - 3148 = 1396 grams
Answer:
The mass of the prism made of lead is 1396 grams than the one made of iron
