Answer:
equivalent i think
Step-by-step explanation:
Selling Price = $145
Charge on first $25 is 5.25%
5.25% of $25 =

Charge on rest is 3.25%
rest amount = $145 - $25 = $120
3.25% of $120 =

Using the
solver function of the calculator, we can find the roots of the polynomial.
x1
= 9.72484
x2 = −5.36242+8.74882i
x3 = −5.36242−8.74882i

Since
dimension cannot be imaginary, therefore the height of the cylindrical hole is
9.72 mm.
Calculating
for radius r:
r
= 9.72 mm – 8 mm
r
= 1.72 mm
The
volume of cylinder is given as:
V
= π r^2 h
V
= π (1.72)^2 (9.72)
<span>V
= 90.34 mm^3</span></span>
Answer:
1) £ 30
2) 80 , £ 720
Step-by-step explanation:
1) marked price = £60
discount = 50%
discount price = 50/100 x 60 = 30
Selling price = 60 - 30 =£ 30
2) marked price = £800
discount = 10%
discount price = 10/100 x 800 = 80
Selling price = 800 - 80 =£ 720
I hope im right!
