The correct answer is C. (1, -3).
In the brackets, the first number
refers to x, and the second to y (like when you write coordinates).
So
we can check what is y ineach of the options and compare whether both of the sided of the equasion are equal:
A. 2x-5=-1, should be 11, false
B.
2x-5=4-9=-5, should be 1, false
C. 2x-5=2-5=-3, should be -3, correct
D.
2x-5=10-5=5, should be -5, false
Answer:
1,174.958 gallons
Step-by-step explanation:
Begin by finding the volume of the cylinder V= π x r² x h
V = 3.14 x 25 x 2 = 157.08
Then multiply 7.48 gallons per cubic foot
7.48 x 157.08 = 1,174.958 gallons
Answer:
-2 < x
Step-by-step explanation:
-6x - 16 < 2x
Add 6x to each side
-6x+6x - 16 < 2x+6x
-16 <8x
Divide by 8
-16/8 < 8x/8
-2 < x
Answer:
$360 I think
Step-by-step explanation:
240 <em>divided</em> by 2/3 = 360
I hope this helps, sorry if it isn't the right answer
The height and radius that will give us the smallest amount of paper, should have should have the perfect dimension, in that the diameter should be equal to the height. thus let the diameter be x, the height will be x and the radius will be x/2
thus the volume of the cone will be:
V=1/3πr^2h
=1/3*π*(x/2)^2*x
=0.262x^3
hence the value of x will be:
33=0.262x^3
x^3=125.95
x=(125.95)^(1/3)
x=5.0126=5.01 cm
thus the diameter=height=5.01cm
