vampirchik [111]

Answer:

Volume, V=3052.08\ ft^3

Step-by-step explanation:

It is given that,

Diameter of spherical boulder is 18 ft

Weight of spherical boulder is 8 tons.

We need to find the volume of spherical boulder. The formula of the volume of sphere is given by :

V=\dfrac{4}{3}\pi r^3

r is radius of spherical boulder, r = 9 ft

Substituting all values in above formula :

V=\dfrac{4}{3}\times 3.14\times (9)^3\\\\V=3052.08\ ft^3

The volume of spherical boulder is 3052.08\ ft^3.

A clothing store offers customers a holiday sale of 20% off the price of x items. A customer then has an additional 15% off coup
aleksandr82 [10.1K]

Finding the equivalent multiplier, it is found that the function for the final price is:

P(x) = 0.68x.

-------------------------------------------

  • There is a holiday sale of 20% off the price of x, thus 0.8x is paid, as 1 - 0.2 = 0.8.
  • Additionally, there is a coupon of 15% off, thus, 0.85 of 0.8x is paid.
  • The equivalent multiplier is:

0.85(0.8) = 0.68

  • Thus, the function for the final price is:

P(x) = 0.68x
