Look at the picture.
The area of the trapezoid:
The area of the rectangle:
The area of figure:
∠W = 16.3°
In ΔVWX, v = 64 cm, w = 18 cm and x=63 cm. Find the measure of ∠W to the nearest degree.
From that above question, we are given 3 sides and we are to find the angle of one of the sides.
We solve using Cosine rule.
∠W = arc cos (v² + x²﹣w²/2vx)
∠W = arc cos (64² + 63² - 18² /2 × 64 × 63)
∠W = arc cos (0.9599454365)
∠W = 16.27137°
∠W = 16.3°
It is given that the bottle temperature begins at the freezer temperature of –16° C. Thus, the initial temperature is –16° C.
Now, sitting on the kitchen counter, the bottle temperature will go up a steady 9.6° C every hour. We need to know how many hours will it take to reach 20° C.
Let us assume that it will take "" hours to reach the required temperature. Then the equation that will guide this system will be a linear one as shown below:
Adding 16 to both sides we get:
Dividing both sides by 9.6 we get:
Thus it will take 3.75 hours (or 3 hours 45 minutes) for the bottle of maple syrup to reach a temperature of celsius.
i did really just add 12+2
hope it help :)
What is the arithmetic mean of the following numbers?<br>
8, 1, 2, 6, 1, 48, 1, 2, 6, 1, 4
7.3 if 48 is a number (I'm not sure if you meant 4,8 or 48)
4 if you meant 48 to be separate
Mean means average so you add up all the numbers then divide the answer by how many numbers there are, so 44/11=4
