Y varies inversely as x. When x=10, y=20. Find y when x=50
IgorC [24]

Answer:

y=100

Step-by-step explanation:

You can solve this by comparing the ratio.

The first set is 10:20 or 1:2 when simplified.

This can then be applied to the second set. If x=50, then 50 times 2 will give you the answer of 100.

dolphi86 [110]

Related diagram is attached below :

Answer:

No

Step-by-step explanation:

The height, h of the tent attached below can be obtained using Pythagoras rule, as the shape forms a right angle triangle.

Length of base , = 24 / 2 = 12 feets

Hypotenus = 15 feets

The height, h = √(hypotenus² - Base²)

h = √15² - 12²

h = √225 -144

h = √81

h = 9 feet

Tent shouldn't be rented as it is below 10 feets

Prove that 6(n+6)-(2n+3) is odd number for all n£N​
Mice21 [21]

Answer:

\begin{aligned}6(n+6)-(2n+3) & = 6n+36-2n-3\\& = 4n+33\\& = 4n + 32 + 1\\& = 2(2n+16) + 1\end{aligned}

Any number multiplied by 2 is even, therefore 2(2n + 16) is even.

If 2(2n + 16) is even, then adding 1 to this makes it odd.

Thus proving that the given expression is an odd number for all n \in \mathbb{N}
