Answer:
16
Step-by-step explanation:
x = number of footballs he can order
22*x + 13 (shipping fee) = 277
22x = 264 Subtract 13 from both sides
x = 16 Divide both sides by 22
Our solution is 16 footballs
Answer:
g(x)=x2−x−6g(x)=x2-x-6
Set x2−x−6x2-x-6 equal to 00.
x2−x−6=0x2-x-6=0
Solve for xx.
Tap for fewer steps...
Factor x2−x−6x2-x-6 using the AC method.
Tap for more steps...
(x−3)(x+2)=0(x-3)(x+2)=0
If any individual factor on the left side of the equation is equal to 00, the entire expression will be equal to 00.
x−3=0x-3=0
x+2=0x+2=0
Set x−3x-3 equal to 00 and solve for xx.
Tap for more steps...
x=3x=3
Set x+2x+2 equal to 00 and solve for xx.
Tap for more steps...
x=−2x=-2
The final solution is all the values that make (x−3)(x+2)=0(x-3)(x+2)=0 true.
x=3,−2
Additive property of zero describes this number sentence.
The meaning of this property is that zero added to any whole number results into the number itself.
Answer: If perpendicular lines intersect, then they form right angles.
Step-by-step explanation:
You take the first part, "perpendicular lines intersect", and add the "if" to it. Then, you take the second part, "to form right angles", and add the "then" in front of it to get your answer, "If perpendicular lines intersect, then they form right angles."
Hope it helps! :)
Volume of the sphere = 3/4 pi r^3
The spheres radius is one third of the hemisphere's so radius of hemisphere = 3r
Volume of the hemisphere = 1/2 * 4/3 pi (3r)^3
= 2/3 * 27 pi r^3
= 18 pi r^3
So vol hemisphere / vol sphere = 18 pi r^3 / 4/3 pi r^3 = 18 * 3/4 = 13.5
Hemisphere is 13.5 times the volume of the sphere.
