3. A bicycle wheel has a diameter of 559 mm and has 32 equally spaced spokes. What is the approximate arc length, rounded to the nearest hundredth, between each spoke? Use 3.14 for (pi) . SHOW YOUR WORK!
If you show work along with correct answer, I will give brainliest.. PLEASE HELP
9514 1404 393
Answer:
54.85 mm
Step-by-step explanation:
The circumference of the wheel is given by ...
C = πd
C = (3.14)(559 mm) = 1755.26 mm
When this is divided into 32 equal arcs, each one of them is ...
(1755.26 mm)/32 = 54.851875 mm
Rounded to the nearest hundredth, the arc length is 54.85 mm.

Find the ten missing angles labeled in the diagram. Line a is parallel to line b. The measures of two angles are given.
Answer:
m∠3 = 112° m∠5 = 38° m∠6 = 68° m∠8 = 74°
You do the others
Step-by-step explanation:
Facts you need to solve this problem.
1. Vertical angles are congruent
2. Alternate interior angles are congruent when lines are parallel
3. Sum of the measures of the angles of a triangle is 180
4. Adjacent angles are supplementary when two lines intersect
m∠3 = 112° (Reason 1 above)
m∠6 = 180 - 112 = 68° (Reason 4)
m∠6 + m∠5 + 74 = 180° (Reason 3)
68 + m∠5 + 74 = 180
142 + m∠5 = 180
m∠5 = 38°
m∠8 = 74° (Reason 2)
That gives you a start, so I will let you find all the others. OK? I know you don't want to do that, but you need to be able to do this type of problem. Now, go for it!!

The length of the slant height is 29.68 centimeters.
What is Pythagoras theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
Given:
The radius, r, of the base is 16 cm.
The height, h, is 25 cm.
To find the length of slant height:
Using the Pythagorean theorem,
l = √(25)² + (16)²
l = 29.68 centimeters.

A sports memorabilia collector needs to create a display case to show her baseball cards
at a garage sale. She will create the case in the shape of a rectangular prism with no lid.
The box will be created by cutting square corners out of a piece of cardboard with
dimensions 40 inches by 60 inches. What equation should be used to maximize the
volume of the box?
Answer:
For a box of length L, width W, and height H, the volume is:
V = H*L*W
in this case, we have a piece of cardboard of dimensions 40in by 60 in.
If we cut squares of side length X in the corners and we fold the corners, we will have a height of X.
And we can define:
Length = 60in - X
Width = 40 in - X
Then the volume of the box will be:
V = X*(60in - X)*(40in - X)
V = X^3 - 100in*X^2 + 2400in^2*X
We want to maximize this, then we need to find the zero of the first derivative.
We have that:
V' = 3*X^2 - 2*100in*X + 2400in^2
V' = 3*X^2 - 200in*X + 2400in^2
This is the equation we will use to maximize the volume of the box, but let's not end here, let's complete the problem and find the value of X and the maximum volume.
We want to solve:
V' = 0 = 3*X^2 - 200in*X + 2400in^2
For X.
Then we can use Bhaskara's formula, we will get that the solutions are:
[tex]X = \frac{-(-200in) +-\sqrt{(-200in)^2 - 4*3*(2400in)} }{2*3} = \frac{200in +- 105.8in}{6}[/tex]
Then we have two possible solutions for X.
X = (200in + 105.8in)/6 = 50.97 in
But this is larger than the side of 40 in, so we can not cut this much, we can discard this option.
The other one is:
X = (200in - 105.8in)/3 = 15.7in
This seems correct.
Then the maximum volume of the box is:
V = 15.7in*(60in - 15.7in)*(40in - 15.7in) = 16,900.893 in^3
