The formula for the volume of a cone is: V = PI x r^2 x h/3
Using the provided dimensions:
V = 3.14 x 2.5^2 x 4/3
V = 26.2 cubic inches.
The answer is C. C=-1
-4(-1)= 4 a negative times a negative is positive
4+5 is 9
28% of 49 is 13.72. So subtract that from 49 and you get 35.28. 35.28 is the price after the sale
Answer: -1
Step-by-step explanation:
− 0.25(−8+12) = -0.25 x 4 =-1
Answer:
x = 2
Step-by-step explanation:
(x² logₓ27) log₉x = x + 4
Use change of base formula.
x² (log 27 / log x) (log x / log 9) = x + 4
Simplify.
x² (log 27 / log 9) = x + 4
x² (log 3³ / log 3²) = x + 4
x² (3 log 3 / (2 log 3)) = x + 4
x² (3 / 2) = x + 4
3x² = 2x + 8
3x² − 2x − 8 = 0
(x − 2) (3x + 4) = 0
x = 2 or -4/3
Since x > 0, x = 2.
