Suppose there is a 1.2°F drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on

Nesterboy [21]

Answer: $49.7^{\circ}F$

Step-by-step explanation:

Given

The temperature on the ground is $56.9^{\circ}F$

temperature drop observed is $1.2^{\circ}F\ \text{per 1000 ft}$

The height of the plane is $6000\ ft$

The total increase in height per $1000\ ft$ is $6$ units

Temperature drop is

$\Rightarrow 1.2\times 6=7.2^{\circ}F$

The temperature at that altitude is

$\Rightarrow 56.9-7.2=49.7^{\circ}F$

If y varies directly as x and y=32 when x=4. find the constant of variation

Llana [10]

Answer:

k = 8

Step-by-step explanation:

Given that y varies directly as x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 32 when x = 4, then

32 = 4k ( divide both sides by 4 )

8 = k

Given that J is between H and K. If JK=3x-1, HJ=2x+4, and HK=12, find x and JK.

cricket20 [7]

Answer:

X=7

Step-by-step explanation:

HJ + JK = HK

3(X + 2) +(3X - 4) = 44

3X + 6 + 3X - 4 = 44

6X + 2 = 44

6X = 42

X = 7
