Answer:
<em>A) -3 + 9 + 4</em>
Step-by-step explanation:
We are given the following information: At 7:00 a.m., the temperature was -3°F. At 6:00 p.m., the temperature was 9°F greater than the temperature at 7:00 a.m. This means the temperature at 6:00 p.m. is calculated as -3 + 9.
We know this last temperature is 4°F less than the temperature at noon, thus the temperature at noon is calculated as -3 + 9 + 4
A) -3 + 9 + 4
Answer:
55.4 in³
Step-by-step explanation:
The formula for the volume of a pyramid can be found:
V =
, where B = area of the base and h = height of the pyramid
Since the base is a triangle, we need to use the formula for the area of a triangle:
A =
= 
Next, multiply the area of the base by the height of the pyramid:
17.67 x 9.4 = 166.098 ÷ 3 ≈ 55.4 in³
