Answer:
The effect of doubling all the dimensions of a triangular pyramid will have on the volume of the pyramid is to increase it by 8 times.
Step-by-step explanation:
i) volume of triangular pyramid = 
Area height
= (Base of triangle perpendicular height of triangle) height
ii) if we double all the dimensions then the three variables((Base of triangle, perpendicular height of triangle, height of pyramid) will be doubled
and the volume of the new pyramid will be 8 times that of the original one.
Answer:
Step-by-step explanation:
This is basically the same as the other question you posted, just with different variables!! make another proportion
252 dollars/18 hours = x dollars/7 hours
252/18 is 14, so
14 = x dollars/7 hours
multiply both sides by 7 to isolate x
98 dollars = x
so john will make $98 for 7 hours of work
Distance between swings and track is 10 in
10 ÷2 = 5
5 × 8 = 40 yards
the distance between track and backed ball court is 4 in
4 ÷ 2 = 2
2 × 8 = 16 yards.
Subtract the two totals.
40 - 16 = 24 yards.
The track 24 more yards than the swing
