Answer:

37.\bar{2}\textdegree C

Step-by-step explanation:

<em>The formula for converting °F to °C is: </em>

<em></em>(\textdegree F -32) \frac{5}{9}=\textdegree C<em></em>

<em></em>

We are given the temperature of 99°F.

=====================================

(99\textdegree F -32) \frac{5}{9}=\textdegree C\\\rule{150}{0.5}\\(67) \frac{5}{9}= \textdegree C\\\\\boxed{37.\bar{2} = \textdegree C}

=====================================

<em>Diane's temperature in Celsius is 37.22...°C.</em>

<em></em>

The 2 is recurring.

=====================================

<em>Hope this helps! </em>

A woman 5 ft tall walks at the rate of 7.5 ft/sec away from a streetlight that is 10 ft above the ground. At what rate is the ti
lesya [120]
Height of the woman = 5 ft
Rate at which the woman is walking = 7.5 ft/sec
Let us assume the length of the shadow = s
Le us assume the <span>distance of the woman's feet from the base of the streetlight = x
</span>Then
s/5 = (s + x)/12
12s = 5s + 5x
7s = 5x
s = (5/7)x
Now let us differentiate with respect to t
ds/dt = (5/7)(dx/dt)
We already know that dx/dt = 7/2 ft/sec
Then
ds/dt = (5/7) * (7/2)
        = (5/2)
        = 2.5 ft/sec
From the above deduction, it can be easily concluded that the rate at which the tip of her shadow is moving is 2.5 ft/sec.

What is the greatest number of rectangles 6cm x 4cm that can be cut from a piece of metal measures 16 cm x 20 cm?
Dominik [7]
Answer:

The greatest number of rectangles that can be cut from the piece of metal = 12

Explanation:

The dimension of the piece of metal = 16cm x 20cm

That is:

Length of the piece of metal = 20 cm

Width of the piece of metal = 16 cm

The dimension of the rectangle = 6cm x 4cm

Length of the rectangle = 6cm

Width of the rectangle = 4cm

The diagram below illustrates how the rectangles can be cut from the piece of metal

Considering the diagrams drawn above, and counting the rectangles formed, we can conclude that the greatest number of rectangles will be cut using the approach on the left, hence the greatest number of rectangles that can be cut is 12
