Answer:
A. $58.50, B. $80
Step-by-step explanation:
mark up percentage 
x 100
30 x 45 = 100SP - 4500
5850 = 100SP
Store Price > therefore, $ 58.50
A. $58.50
<em>Actual Price :</em>
130 AP = 10400 - 100AP
AP > $80
B. $80
Sin^-1(5/13) = 22.6
sin(22.6/2) = 0.196
The number of buckets is directly proportional to the area and the thickness of the wall and inversely proportional to the amount of paint. Mathematically, we can write:
n = k · (a · t) / p
where k is the proportionality constant which we do not know.
We can calculate k with the given data: 5 2-gallon buckets, area of 100 square feet and thickness 3 inches:
k = (n · p) / (<span>a · t)
= (5 </span>· 2) / (100 · 3) = 0.0333
Now that we know the constant, we can calculate the area that can be painted with 8 2-gallon buckets if the thickness is 6 inches:
a = (n · p) / (k<span> · t)
= (8 </span>· 2) / (0.0333 · 6)
= 80 ft²
Please, note that we made sure to have the exact same units of measurements than the previous case.
Therefore, the correct answer is an area of 80 ft².
Answer:
No
Step-by-step explanation:
Ratio of areas = (Ratio of diameters)²
Ratio of areas = 2² = 4
Answer:
3x^3-18x^2+26x-8
Step-by-step explanation:
(x-4)(3x^2-6x+2)
3x^3-6x^2+2x-12x^2+24x-8
