1. 75 x 42 x 3
= 9450 cm2
2. total volume = 75 x 42 x 48
= 151200 cm2
Speed of fly-by-night airplane is 617.5 miles per hour
<em><u>Solution:</u></em>
Given that,
The max speed of a fly-by-night airplane is 346 miles faster than a soaring wing airplane
Let "x" be the speed of saoring wing airplane
Then,
Speed of fly-by-night airplane = 346 + x
The sum of their speeds is 889 miles per hour
Therefore,
speed of saoring wing airplane + speed of fly-by-night airplane = 889
x + 346 + x = 889
2x + 346 = 889
2x = 889 - 346
2x = 543
x = 271.5
Thus speed of fly-by-night airplane = 346 + x = 346 + 271.5 = 617.5
Thus speed of fly-by-night airplane is 617.5 miles per hour
The STQ is obtuse i think that’s it?
Answer:
640 ft^3
Step-by-step explanation:
In this case we must divide the area into two parts, in the prism and in the pyramid, the sum of the volume of these parts would be the total volume
However
for the volume of the prism it would be the multiplication of the three sides, that is:
8 * 8 * 9 = 576
i.e. 576 ft ^ 3
For the pyramid, the formula is the multiplication of the area of the base by the height divided by 3, we know that the area of the base is 8 * 8 and that the height is 3, therefore:
8 * 8 * 3/3 = 64
64 ft ^ 3 is the volume of the pyramid
The total would be:
576 + 64 = 640
Total volume would be 640 ft ^ 3
