HELP 1)The number of hours it takes for a block of ice to melt varies inversely as the temperature. If it takes 2 hours for a square
inch of ice to melt at 65º, find the constant
of variation.
2) The cost per person to rent a mountain
cabin is inversely proportional to the number
of people who share the rent. If 5 people
share and it costs $36 per person, find the
constant of variation.
3) The width of a rectangle varies inversely with
its length. If the width is 4 when the length is
12, find the width when the length is 16.
4) The pitch of a musical note varies inversely
as its wavelength. If the tone has a pitch of
440 vibrations per second and a
wavelength of 2.4 feet, find the pitch of a
note that has a wavelength of 1.6 feet.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
