Answer:
18.84 cm
Step-by-step explanation:
P = 2 × pi × r
= 2 × 3.14 × 3cm
= 6cm × 3.14
= 18.84 cm
The amount of sales (S) of statin in billions of dollars by 2017 is 34.5 billions
<h3>Linear equations</h3>
Linear equation are equation that has a leading degree of 1. Given the equation that represents Statins used to keep cholesterol in check and are a top-selling drug in the U.S.
S-1.5x = 6
where
S is the amount of sales
x is the number of years after 1998
By 2017, the total number of years is 19 years
Substitute
S = 1.5x + 6
S = 1.5(19) + 6
S = 28.5 + 6
S = 34.5
The amount of sales (S) of statin in billions of dollars by 2017 is 34.5 billions

Answer:
5/6 mile
Step-by-step explanation:
The formula for the area of a rectangle can be used with the given values to write an equation for the length of the farmland.
__
Here is the equation for the area of a rectangle.
A = LW . . . . . area is the product of length and width
When we fill in the area and width, we have ...
5/9 mi² = L(2/3 mi) . . . . . equation for the length of the farmland
Solving this equation gives ...
L = (5/9)/(2/3) mi . . . . . . . . divide by the coefficient of L
L = (5/9)/(6/9) mi = 5/6 mi . . . . . perform the division
The length of Sandra's farmland is 5/6 mile.
