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!!

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.

At a construction job for a museum there are 16 painters. Of these painters, 25% of them paint the interior of the museum. How many painters are painting the interior
Answer:
4 painters
Step-by-step explanation:
At a construction job for a museum there are 16 painters. Of these painters, 25% of them paint the interior of the museum. How many painters are painting the interior?
From the question:
Total number of painters = 16 painters
Percentage of painters that paint the interior = 25%
The number of painters painting the interior is calculated as:
25% of 16 painters
= 25/100 × 16 painters
= 4 painters
Therefore, the number of painters painting the interior = 4 painters

Subtract 1 4/8 from 5 since Maya used 1 4/8 lb:
5 - 1 4/8 = 3 4/8 or 3 1/2 lb of sugar
10x + 6 = -2x + 18 solve for x
Answer:
x=1
Step-by-step explanation:
10x + 6 = -2x + 18
add 2x to both sides
10x+6+2x =18
subtract 6 from both sides
10x+2x=18-6
add like terms
12x=12
divide by 12 on both sides
x=1

Find the perimeter of the following rectangle,
Write your answer as a mixed number in simplist form,
Be sure to include the correct unit in your answer.
[tex]perimeter = 2(3 \frac{1}{10}) + 2 (\frac{3}{4}) [/tex]
[tex]perimeter = \frac{31}{5} + \frac{3}{2} [/tex]
[tex]perimeter = \frac{62}{10} + \frac{15}{10} [/tex]
[tex]perimeter = \frac{77}{10} [/tex]
[tex]perimeter = 7 \frac{7}{10} [/tex]
The unit is just cm.
//
I might not be right. Double check to make sure. Hope that gives you a general idea of how to do it.
Answer:
Perimeter of rectangle =2(l+b)
=2(3*1/10+3/4)
=2(3/10+3/4) (lcm=40)
=2(12/40+30/40)
=2(42/40)
=42/20
= 21/10
=21/10 cm

Jane and Sali cycled along the same 63km route. Jane took 3.5 hours to cycle the 63km.
Sali started to cycle 4 minutes after Jane started to cycle.
Sali caught up with Jane when they had both cycled 30km.
Jane and Sali both cycled at constant speeds.
Work out Sali's speed in km/h.
Answer:
sali's speed was 18.75 km/h
Step-by-step explanation:
Jane took 3.5 hours to cycle the 63 km.
As, , so the speed of Jane will be:
Suppose, the speed of Sali is km/h
Sali caught up with Jane when they had both cycled 30 km.
So, the time required for Jane to cycle 30 km and the time required for Sali to cycle 30 km
Given that, Sali started to cycle 4 minutes or after Jane started to cycle. So, the equation will be.......

Brenda had 3/4 of a pizza. Her sister ate 1/2 of her pizza. How
much pizza did Brenda's sister eat?
her sister are two slices of pizza,
you multiply 1/2 to make it equivalent to 3/4 so once you multiply it should turn out to be 2/4 which means her sister ate 2 slices,lmk if 2 was an option.
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
A resteraunt buys 9 pounds of truffles.Suppose truffles cost 168$ per ounce. How much would the resteraunt pay for truffles
Answer:
$24,192
Step-by-step explanation:
Cost of truffles = $168 per ounce
Amount of truffles bought = 9 pounds
Amount to be paid for truffles :
Converting the amount of truffles bought to ounces :
1 pound = 16 ounces
Hence, total amount of truffles bought in ounces :
(16 * 9) = 144 ounces
Hence, amount it be paid :
144 * $168
= $24,192
