Answer:

$\boxed {\tt -4 \textdegree \ per \ hour }$

Step-by-step explanation:

This question asks us to find the average rate of change in temperature per hour.

Therefore, we must divide the temperature change by the hours.

$rate \ of \ change =\frac{temperature \ change}{hours}$

The temperature dropped 24 degrees in 6 hours. Since it dropped, the change was negative.

$temperature \ change = -24 \textdegree \\hours = 6 \ hours$

Substitute the values into the formula.

$rate \ of \ change =\frac{-24 \textdegree}{6 \ hours}$

Divide.

$rate \ of \ change = - 4 \textdegree / hour$

The average change in temperature was -4° per hour. The temperature dropped 4 degrees each hour.

The function h (d) = 2d + 4.3 relates the height (h) of the water in a fountain in feet to the diameter (d) of the pipe carrying

mezya [45]

Answer:

h(1.5) = 7.3 ft

h(10.3) = 24.9 ft

Step-by-step explanation:

Given the function h(d) = 2d + 4.3,

where:

h = height of the water in a fountain (in feet)

d = diameter of the pipe carrying the water (in inches)

Substitute the input value of d = 1.5, into the function:

h(1.5) = 2(1.5) + 4.3

h(1.5) = 3 + 4.3

h(1.5) = 7 feet

The height of the water in a fountain is 7 feet when the diameter of the pipe is 1.5 inches.

Substitute the input value of d = 10.3, into the function:

h(10.3) = 2(10.3) + 4.3

h(10.3) = 20.6 + 4.3

h(10.3) = 24.9 feet

The height of the water in a fountain is 24.9 feet when the diameter of the pipe is 10.3 inches.

<h3>Context of the solutions to h(1.5) and h(10.3):</h3>

The solutions to both functions show the relationship between the diameter of the pipe to the height of the water in a fountain. The height of the water in fountain increases relative to the diameter of the pipe. In other words, as the diameter or the size of the pipe increases or widens, the height of the water in a fountain also increases.

If the perimeter of Triangle XYZ is 56 cm, what is the perimeter of Triangle ABC?

Troyanec [42]

Answer:

28 cm

Step-by-step explanation:

Triangle ABC is obtained by joining the mid points of the sides of triangle XYZ.

So, perimeter of triangle ABC will be equal to half of the perimeter of triangle XYZ.

$P(\triangle ABC) = \frac{1}{2} \times P(\triangle XYZ)$
