Lee's shoe size would be a 9
9 6 6
Range = biggest value - smallest value
9-6 = 3
Answer:
20 m
Step-by-step explanation:
The distance from the top car to the bottom car is equal to the diameter of the wheel. The diameter is 40 m, and that is twice the radius. The radius of the Ferris wheel is (40 m)/2 = 20 m.
Answer:
Width of the rectangular banner is
ft.
Step-by-step explanation:
Area of the rectangular banner =
square feet
=
square feet
Area of rectangle is given by,
Area = Length × Width
Length of the banner =
feet
From the formula,

W = 
= 
= 
=
ft
Therefore, width of the rectangular banner is
ft
I think instead of "conjunction" it should say "conjecture"
Anyways, draw out a quadrilateral (see figure 1 attached). It can be any figure with 4 sides. Label the angles as A, B, C and D. The conjecture to prove is that A+B+C+D = 360. In other words, the sum of the four angles of any quadrilateral is always 360 degrees.
Draw a segment from A to C. This segment will cut the quadrilateral into two triangles. Re-label angle A to angle E and F. Do the same for angle C (label it G and H). Essentially, angle A = E+F and angle C = G+H.
See figure 2. Notice how I've color-coded things. The blue angles correspond to one triangle while the red angles correspond to the other triangle.
Since we know that three angles of a triangle always add to 180, we can say
B+G+E = 180
F+D+H = 180
Add the two equations (add left side separately; do the same for the right side)
Doing so leads to
B+G+E+F+D+H = 180+180
(E+F) + B + (G+H) + D = 360
A+B+C+D = 360
Which proves the conjecture
A reference angle is formed by the terminal side and the horizontal axis (aka x axis). Replace each "access" with "axis" as those are typos. By definition, a reference angle is between 0 and 90 degrees so the angle is always acute.
Answer: Choice B
