Answer:
-0.017°c/km
Step-by-step explanation:
for the contour provided , to estimate the value of directional derivative of this temperature function at Dubbo, New South Wales in the direction of sydney.
to also find the units,
it is posible to find the directional derivative for the temperature by calculating the rate of change of temperature on an average. This is found in between points at which a straight line can be drawn in between cities that crosess the zone temperature.
to find the direction of sydney, the change in temperature is from 30 to 24 degrees. from the scale that is there, the distance between the two cities are 350km
thus,
24 -30/350
= -0.017deg/km
therefore the required value is -0.017°c/km
Answer:
You can use a calculator to divide 38,700 by 45,600; you get a decimal number slightly less than one then you can proceed to shift the decimal point two spaces toward the right and you have that as a percentage when your done.
Step-by-step explanation:
Answer: B
Step-by-step explanation:
Running at the same constant rate, 6 identical machines can produce a total of 270 bottles per minute. Since the machines are identical and running at the same constant rate, it means each of them as the same rate. The rate of each machine can produce would be determined by dividing the combined unit rate by 6. It becomes
270/6 = 45 bottles per minutes
The rate for 10 machines running at the same constant rate would be
10 × 45 = 450 bottles per minutes.
If the 10 machines produce 450 bottles per minutes, then,
In 4 minutes, the 10 machines will produce 4 × 450 = 1800 bottles
Answer:
A
Step-by-step:
a^2+ b^2 = c^2
if we try A
6^2+8^2 = 10^2 => 64+36 = 100
Volume is length x width x height.
Calculate the volume of each rectangle and add them together.
7.5 x 7.5 x 3.55 = 199.6875
7.5 x 3.55 x 3.55 = 94.51875
Volume = 94.51875 + 199.6875 = 294.21 cubic meters
