The puzzle is
1+1(4)
2+2(3)
etc
so 4+1 = 8
Answer:B or C
Step-by-step explanation:
Answer:
The rate of change was 3.5 degrees / h.
Step-by-step explanation:
In order to calculate the rate of change we need to divide the variation of temperature by the variation of time. Since the time is given to us in a 12 h format (am/pm), we first need to convert it to 24 h. To do that we sum the time that is "pm" by 12, we have:
time2 = 3 + 12 = 15
Therefore the rate of change in temperature is:
rate = variation of temp / variation of time
rate = (temp final - temp init) / (time final - time init)
rate = (82 - 54) / (15 - 7) = 28 / 8 = 3.5 degrees / h
The rate of change was 3.5 degrees / h.
We compute for the surface area of the triangular prism by the adding the areas of the bases and the sides. There are two triangles and the areas will be,
A = 2 (1/2)(9 cm)(12 cm) = 108 cm²
There are three sides which are in rectangular shape.
A1 = (10)(12) = 120 cm²
A2 = (10)(9) = 90 cm²
A3 = (10)(15) = 150 cm²
The sum of these areas is 468 cm².
