Find the measure of an interior angle of a regular dodecagon(12-sided polygon). Hint: Sum = (n-2)180
Answers
Step-by-step explanation:
Sum of interior angles in a polygon = 180°(n - 2).
Size of interior angle in a regular polygon
= 180° - 360°/n
= 180° - 360°/12
= 180° - 30°
= 150°.

AB and BC form a right angle at point B. If A= (-3,-1) and B = (4,4), what is the equation of BC?
A. x+3y= 16
B. 2x+y= 12
C. -7x - 5y=-48
D. 7x-5y= 48
Answers
Answer: We have then:
y-yo = m (x-x0)
m = (y2-y1) / (x2-x1)
m = (4 - (- 1)) / (4 - (- 3))
m = 5/7
We choose an ordered pair:
(xo, yo) = (4, 4)
Substituting:
y-4 = (5/7) (x-4)
y = (5/7) x-20/7 + 4
7y = 5x - 20 + 28
7y = 5x + 8
y = (5/7) x + 8/7
The equation of the perpendicular line is:
-7x - 5y = -48
Answer:
the equation of BC is:
(C) -7x - 5y = -48

In the diagram. PQ is parallel to BC.
APB and AQC are straight lines.
PQ = 8 cm, BC = 10 cm and AB = 9 cm.
Calculate PB
Answers
Answer:
PB = 1.8
Step-by-step explanation:
PQ = 8 cm, BC = 10 cm and AB = 9 cm
∆ABC is similar to ∆APQ.
Therefore:
[tex] \frac{AB}{AP} = \frac{BC}{PQ} [/tex]
Plug in the values
[tex] \frac{9}{AP} = \frac{10}{8} [/tex]
Cross multiply
AP × 10 = 8 × 9
AP × 10 = 72
Divide both sides by 10
AP = 7.2
PB = AB - AP
PB = 9 - 7.2
PB = 1.8

A jewelry store is having a going out of busniess sale. All merchandise is marked 40% off the reguler price. The regualr price of a watch is $59.95. Find the amount of the discount and the sale price.
Answers
Answer:
Amount of the Discount: $23.98
Sale Price: $35.97
Step-by-step explanation:
In order to calculate the discount we first need to turn this percentage into a decimal by dividing it by 100. Once we have it in decimal form we subtract that value from 1. Finally, we multiply this new decimal by the original price in order to obtain the sale price like so...
40 / 100 = 0.40
1 - 0.40 = 0.60
0.60 * 59.95 = 35.97
Now we have the sale price which is $35.97 now we can subtract this value from the original price to calculate the amount of the discount.
59.95 - 35.97 = 23.98

carmen has a bag of p peaches. she adds 10 peaches to the bag. then she shares all the peaches equally among 5 friends.write an expression that represents the number of peaches each friend receives. show your work.
Answers
Answer:
Step-by-step explanation:
We start with 10 peaches. Divided with 5 friends. So an equation would be 10÷5= 2. Each friend got 2 peaches.
The expression that represents the number of peaches each friend receives will be (p + 10)/5.
What is the value of the expression?When the relevant components and basic processes of a numerical method are given values, the expression's result is the result of the computation it depicts.
Carmen possesses a bag of p peaches. She stuffs the bag with ten peaches. Then the number of peaches will be given as.
⇒ p + 10
Then she divides the peaches evenly among five companions. Then the number of peaches will be given as,
⇒ (p + 10) / 5
The expression that represents the number of peaches each friend receives will be (p + 10)/5.
