Does the point (25,75) lie on a straight line y=3x. How do you know that
Answers
you know this because when you look at the point (25,75) you should automatically think (x,y) where "x" is what you plug in to the line to get "y" which is your output.
so that being said if you plug in 25 ...
y= 3(25)
you want your answer to be 75. if it is then this point exist on the line if it isnt then it does not exist on this line.
in this case 3*25 does in fact equal 75 so the point (25,75) exist on the line y=3x

sphere with the radius of 9: 3/4(pi)9^3 = 3053.63
sphere with the radius of 6: 3/4(pi)6^3 = 904.78
the difference: 2148.85
Volume of a sphere=(4/3)πr³
Difference of the volumes of the spheres=(4/3)πr₁³ - (4/3)πr₂³=(4/3)π(r₁³-r₂³)
Data:
r₁=9 ft
r₂=6 ft
then :
Difference of the volumes of the spheres=4/3π[(9 ft)³ - (6 ft)³]=(4/3)π(513 ft³)=
≈2148.85 ft³.
Answer: 2148.85 ft³

First part:
The triangle would look like a triangle only if the third side is 7 inches.
The third side could be 6 inches, but then all 3 sides would lie on a straight
line, and you couldn't tell that it's a triangle.
The third side can't be 4 inches or 5 inches, because it would be too short
to join the ends of the first 2 sides.
Second part:
If the angles are supplementary, that means that
they add up to 180° .
Let's addum up:
10x + 70° = 180°
Subtract 70° from each side: 10x = 110°
Divide each side by 10: x = 11°
