Melanie connected a brown garden hose, a green garden hose, and a black garden hose to make one long hose. The brown hose is 10.
natta225 [31]

Answer:

35.65 feet

Step-by-step explanation:

Melanie connected a brown garden hose , a green garden hose and a black garden hose to make one long hose

The brown hose is 10.75 feet

The green hose is 16.4 feet

The black hose is 8.5 feet

Therefore the farthest distance that the one hose can reach can be calculated as follows

= 10.75 + 16.4 + 8.5

= 35.65 feet

Hence the farthest distance that one hose can reach is 35.65 feet

Please answer hurry!!!!
lutik1710 [3]
The best way to solve this problem is by plugging in each answer choice for both equations and seeing which one works. You can already see that choice A doesn't work because -1 is not greater than or equal to 4. That means you just need to test choices B and C!

Choice B (4, -2)
x + y  \geq 6\\
4 + -2  \geq 6\\
2  \geq  6 

2 is not greater than or equal to 6, so choice B doesn't work.

Choice C (4, 2)
x + y \geq 6\\ 
4 + 2 \geq 6\\ 
6 \geq 6 \\\\
x  \geq 4\\
4 \geq 4
Since 6 is equal to 6 and 4 is equal to 4, choice C works!

What is the volume of the cylinder below?
Anestetic [448]

Answer:

B

Step-by-step explanation:

The formula for volume of cylinder is given below:

volume of cylinder = \pi r^2 h

Where r is the radius (here, it is given as 3)

h is the height, the perpendicular distance from base to top (here, it is 4 NOT 5 since 5 is the 'slant height')

Plugging in the available info , we get our answer:

\pi r^2 h\\=\pi (3)^2 (4)\\=36\pi

B is the correct answer
