The answer I think is (c) 3
It’s A. 10 feet is 10/3 yards and if you multiply that by 4 you get 40/3. Simplify the fraction and you get 13 1/3
The slope of line T is -1/5, because perpendicular lines have opposite reciprocal slopes, meaning the opposite sign (positive or negative) and flipped (whole number becomes a fraction).
Answer:
Step-by-step explanation:
square-based pyramid:
volume V = (⅓)b²h
= (⅓)7²·16
≅ 261.3 ft³
:::::
Can't help with question 3. I haven't learned triangle-based pyramids.
:::::
cone:
volume V = ⅓πr²h
= ⅓π17²·20
= 6052.8 yd³
:::::
can't help with question 7. Never did this kind of pyramid.
Plug the x in :)
3(2) + 8
6 + 8
=14
