Answer:
1256 cm
Step-by-step explanation:
First we must find the perimeter, because the perimeter is equal to 1 revolution.
The perimeter of any circle is Pi(Diameter)
3.14*20
62.8 cm is the perimeter of the bike wheel.
Because the perimeter is basically a revolution, we can multiply 62.8 by 20 to get:
1256 cm
Answer:
48
Step-by-step explanation:
If the follows triangle congruence, you look at the two triangles given.
Triangle XYZ is equiangular due to it's 3 congruent angles.
Since Triangle XYZ is equiangular, that means it is also equilateral, meaning each side is congruent.
This means that side XY and Side ZY are equal to XZ and therefore
XY = 11 and ZY = 11.
Then we look at Triangle WXZ. Triangle WXZ has two congruent base angles, meaning it's an isosceles triangle.
By the converse of the isosceles triangle theorem, if 2 angles of a triangle are congruent then the sides opposite those angles are congruent.
This means XZ and WZ are congruent to each other, meaning XZ = WZ.
Since XZ= 11, that means WZ = 11.
Now we have all outside side lengths and we can find the perimeter.
Perimeter = WX + WZ + ZY + XY.
(substitute known values of sides)
11+11+11+15= Perimeter
33+15 = Perimeter
48 = Perimeter

Answer:
t = 1/2 ÷ 1/4
t = 2 hours
Step-by-step explanation:
Time spent watching movies = 1/2 of an hour
This accounts for 1/4 of the total time thei spend at mount rushmore.
1/2 = 1/4t
Where t = total time they spent at mount rushmore (hours)
1/2 = 1/4t
Determine the equation to find t
t = 1/2 ÷ 1/4
= 1/2 × 4/1
= 4 / 2
= 2
t = 2 hours
Correct! 12 is a multiple of 6 and 8 is a multiple of 4.
